[0020] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0021] Based on this, this application proposes a marine ranch management method based on a release strategy, such as Figure 1 As shown, the method may include the following steps:

[0022] S10. Obtain multiple habitat suitability indexes corresponding to multiple target species of the target marine ranch, energy flow relationship data of multiple target species, current ecological capacity of multiple target species, and marine dynamic environment data. Among them, generalized additive models (GAM) are used to select variable factors for each target species, and the weight analysis of the factors is performed through the boosting regression tree model (BRT), and a habitat suitability index (HSI) model is constructed to evaluate the habitat suitability index of the target marine ranch. In this embodiment, the target species of the marine ranch can include algae, shellfish, fish, shrimps and crabs, etc. Some species are species sown when the marine ranch is built, such as algae, and some species can be species for cyclic release, such as shellfish, shrimps and crabs.

[0023] The biological resource survey data and consumer biological food data of the target marine ranch can be determined by investigating the species of the marine ranch, as well as the wild species information corresponding to the target species, other species information with the target species in the food web relationship, and the marine ranch environmental data corresponding to the target species, wherein the marine ranch environmental data includes seawater quality, marine sediments, plankton, fishery resources, benthic organisms, and artificial reef biological attachment. The energy flow relationship of the target species is constructed based on the investigated biological resources, food web, etc. In this embodiment, the energy flow relationship includes the types of target species at each trophic level and the feeding and competition relationship between each target species.

[0024] The ocean dynamic environment data may include the surface, middle and deep seawater flow data of the marine ranch and its surrounding waters, for example, the flow data of the surface layer due to wind, tides, etc., the flow data of the middle and deep layers due to ocean currents, and the flow data of the surface, middle and deep layers due to convection, etc.

[0025] S20. Determine an initial release strategy for at least one target species in the target marine ranch based on the habitat suitability index and the current ecological capacity, wherein the release strategy includes at least the release timing, release size and release quantity.

[0026] By calculating the suitability index of the target species in the target marine ranch, the abundance of resources related to the target species in the target marine ranch is determined. Then, the influence of the number of target species released on the habitat suitability index is determined to reversely constrain the maximum number of target species released. Therefore, the reasonable number of target species released can be determined by the habitat suitability index and the current ecological capacity.

[0027] In order to obtain the appropriate release size and release timing, the ecological capacity (i.e. current ecological capacity) and growth characteristics of the wild population corresponding to the target species must also be considered. For example, at least two factors need to be considered for the release size and release timing. For the release size, since the competitiveness of the released species is weaker than that of wild species of the same size, the release size should be slightly larger than that of the wild species. In addition, the consideration of the release timing requires the abundance of the food source of the species after release.

[0028] Exemplarily, the initial release strategy for the target species of the target marine ranch determined based on the habitat suitability index and the current ecological capacity includes: obtaining growth change data of wild species corresponding to the target species, information on other species that have a food web relationship with the target species, and marine ranch environmental data corresponding to the target species, and determining the release quantity of the target species based on the current ecological capacity of the wild species and the marine ranch environmental data; predicting the growth change data of the target species based on the other species information to determine the predicted growth change data of the target species; determining the release size and release timing of the target species based on the predicted growth change data of the target species and the corresponding growth change data of the wild species; and using the release quantity, the release size, and the release timing as the initial release strategy.

[0029] In this embodiment, the target species is the swimming crab trituberculate as an example, and the relationship between the released swimming crab trituberculate and the wild population is often the following:

[0030] In terms of feeding competition: the adaptability of released swimming crabs to the environment is much worse than that of wild populations. Therefore, the competitiveness of released swimming crabs of the same size is much smaller than that of wild populations. However, too large a release size will also form reverse competition with wild populations, resulting in a decrease in the competitiveness of wild populations. Therefore, it is necessary to adjust the release size and release time based on the current number and size of wild populations.

[0031] In terms of predation: the released swimming crabs face the same predators as the wild populations during the larval stage. Properly increasing the total population of swimming crabs is conducive to improving the proliferation effect of releasing swimming crabs.

[0032] At the genetic level: since the released juveniles are bred from a limited number of parents, whose genetic composition is relatively similar, large-scale release may lead to changes in population gene frequency, loss of genetic diversity, and decreased genetic fitness. Therefore, it is necessary to further limit the number of releases through genetic factors.

[0033] In this embodiment, environmental factors, as well as the food source quantity of the swimming crab, the food competitors of the swimming crab and the predators of the swimming crab were evaluated based on the habitat suitability index.

[0034] The current vitality of the wild population is evaluated by environmental factors determined by the habitat suitability index, and the first competitiveness of the wild population and the second competitiveness of the released population are evaluated based on the food source and current vitality of the three-spotted swimming crab in the target area. Based on the first competitiveness and the second competitiveness, the release size of the released population that achieves the same competitiveness as the wild population is determined. In one embodiment, the relationship between the release size and the size of the wild population can also be determined based on a preset coefficient. For example, the size of the wild population can be 80%-90% of the release size, and its feeding competitiveness is equivalent.

[0035] To determine the timing of release, we can first determine multiple candidate time periods through the habitat suitability index, and then determine the wild population size at each preset growth node through the growth characteristics of the wild population, select the candidate preset growth node corresponding to the appropriate wild population size, and take the time period where the candidate preset growth node overlaps with the candidate time period as the release time.

[0036] In another embodiment, it is also necessary to consider the different effects of food sources of the target species to be released at different times. When predicting the growth change data of the target species based on the information of other species and determining the predicted growth change data of the target species, the first key prey species information of the target species in the seedling stage and the second key prey species information of the target species in the mature stage can be obtained, taking into account the different food sources at different times; the competing species information of the target species is obtained; the growth change data of the target species is predicted based on the growth characteristics of the first key prey species information and the second key prey species information and the competing species information to determine the predicted growth change data of the target species.

[0037] Exemplary, taking the swimming crab of three tubercles as an example, the swimming crab of three tubercles is one of the omnivorous animals, generally taking shellfish, miscellaneous fish, miscellaneous shrimps, etc. as food sources, in addition, the tender shoots of algae and aquatic plants are also used as part of the food sources, and the food sources of the swimming crab of three tubercles are different in different growth stages. In the seedling stage of the swimming crab of three tubercles, it is an omnivorous phenomenon, mainly feeding on small individuals such as plankton, and after entering the adult stage, it mainly takes shellfish, miscellaneous fish, etc. as the main food sources. Therefore, in this embodiment, the distribution of the first key prey species information of the target species in the seedling stage and the second key prey species information of the target species in the mature stage, such as reproduction, growth, and maturity, can be used to determine the abundance of food sources in the target sea area, and then it can be used as one of the predictive factors of the growth change data of the target species, so as to more accurately predict the growth change data of the target species.

[0038] Similarly, the growth information and quantity of the target species' competing species and predator species are also used as one of the predictive factors for the growth change data of the target species, so as to more accurately predict the growth change data of the target species.

[0039] S30. Obtain an ecosystem evaluation result of the target marine ranch after release using the initial release strategy, and based on the ecosystem evaluation result and the ocean dynamic environment data, perform an ecological evaluation of the target marine ranch for each target species within the growth cycle, to obtain a dynamic ecological evaluation result of the target marine ranch based on the initial release strategy.

[0040] After release, the biological community of the marine ranch will change, and the ecological environment will also change. Therefore, in this embodiment, an ecosystem evaluation is performed on the target marine ranch after release according to the initial release strategy. In this embodiment, the health status of the ecological environment of the target marine ranch after release can be evaluated, and the stability of the ecosystem can also be evaluated.

[0041] Exemplarily, at least one target species is released into the target marine ranch with an initial release strategy, and after the release, dynamic ecological environment data of the target marine ranch during the growth cycle of the target species is dynamically acquired; an ecological assessment is performed on the dynamic ecological environment data to determine the health status evaluation results and ecosystem stability evaluation results of the target marine ranch.

[0042] In this embodiment, the biome index method can be used to conduct a health assessment on the ecological environment data of the target marine ranch after release to determine the health status evaluation result of the target marine ranch; the biome index method includes the AMBI index method and the IBI index method; the ecosystem model method is used to conduct a stability assessment on the ecological environment data to determine the ecosystem stability evaluation result of the target marine ranch. At least one of the health status evaluation result and the ecosystem stability evaluation result is used as the ecosystem evaluation result of the marine ranch after release.

[0043] Among them, the AMBI index method can use the relative abundance of disturbance-sensitive organisms, the relative abundance of disturbance-insensitive organisms, the relative abundance of disturbance-tolerant organisms, the relative abundance of second-order opportunity species, and the relative abundance of first-order opportunity species to evaluate the health status. The evaluation system of the IBI index method is constructed by analyzing the species composition, diversity, and functional structure of various communities in the target marine ranch. The index value evaluates the integrity of the biological community under study from a temporal and spatial perspective.

[0044] As a relatively open water ecosystem, marine ranches exchange water with adjacent water ecosystems. Therefore, when using the biome indicator method to conduct health assessments on ecological environmental data and using the ecosystem model method to conduct stability assessments on ecological environmental data, ocean dynamic data must also be considered. Therefore, ocean dynamic data is used to calculate the material exchange and replenishment of the marine ranch system through water exchange, and the changes in the biome in the target sea area are determined through real-time material exchange, which are then mapped to the AMBI index and the IBI index. The health status assessment and the ecosystem stability assessment are adjusted to obtain the comprehensive ecological evaluation results.

[0045] In this embodiment, the real-time water exchange data between the target marine ranch and the adjacent water ecology is determined based on the marine dynamic environment data; the health status evaluation result and the ecosystem stability evaluation result are dynamically adjusted based on the real-time water exchange data to obtain the dynamic ecological evaluation result. In this embodiment, water exchange may directly bring energy supplementation, such as the supplementation of primary productivity and secondary productivity, and may also bring supplementation of direct food sources of target species. Water exchange may also bring supplementation of nutrients, thereby driving the supplementation of primary productivity and secondary productivity. In this embodiment, the energy / material supplementation of the target marine ranch can be evaluated by the marine dynamic environment data. Exemplarily, an evaluation model can be constructed with marine dynamic environment data as input and energy supplementation of the target area (including direct or indirect productivity supplementation and direct food source supplementation of target species) as output. The evaluation model can be constructed with a machine learning model or a deep learning model, such as a support vector machine model, a CNN network, etc., and a training set is constructed through historical data for training. After the training is completed, the energy / material supplementation of the target marine ranch is evaluated or predicted. After obtaining the evaluation or prediction results, the impact coefficient of the real-time water exchange data on each trophic level in the ecosystem in the target marine ranch is determined based on the material replenishment amount; the health status evaluation result and the ecosystem stability evaluation result are dynamically adjusted based on the impact coefficient to obtain the dynamic ecological evaluation result.

[0046] S40. Construct an Ecopath energy flow model corresponding to the target marine ranch using a plurality of the target species as functional populations of the target marine ranch, and utilize the Ecopath energy flow model to evaluate the aquaculture carrying capacity based on the energy flow relationship data, dynamic ecological evaluation results and the marine dynamic environment data to obtain the aquaculture carrying capacity of the target marine ranch.

[0047] Among them, the Ecopath energy flow model is constructed based on the Ecopath model, which is a mass balance model based on the ecosystem approach. According to the theory of trophic dynamics, the input and output of materials or energy of a biological functional group in the ecosystem are balanced, that is, productivity is equal to the sum of predation deaths, biological accumulation, catch, migration and other deaths.

[0048] In this embodiment, multiple target species in the target marine ranch are used as functional populations to construct 13 to 50 functional groups. Through the types of target species at each trophic level and the feeding and competition relationship between each target species, each channel of energy flow from organic matter through primary production, secondary production to top predators in the target marine ranch is determined to ensure that the functional groups defined based on the target species can cover the entire energy flow process of the target marine ranch. At the same time, since the marine ranch is a relatively open water ecosystem, the water exchange between the marine ranch and the adjacent water ecosystem has the effect of replenishing material energy on the target marine ranch system. With the accumulation of time, in some areas with large water exchange, the cumulative amount of energy replenishment brought by water exchange may have a greater impact on the transfer of energy in the food web. Therefore, in the embodiment, by considering the cumulative water exchange data of the water exchange determined by the marine dynamic environment data during the growth period of the target species, and then evaluating the impact of the cumulative energy replenishment of the target marine ranch on the energy flow in the food web, the marine ranch biocapacity can be more accurately evaluated.

[0049] In this embodiment, the Ecopath energy flow model is used to evaluate the biocarrying capacity of the target species based on the energy flow relationship data; the ocean dynamic environment data and the cumulative water exchange data between the target marine ranch and the adjacent water ecology during the growth period of the target species are used; the cumulative energy replenishment of the target marine ranch is evaluated based on the cumulative water exchange data; and the aquaculture carrying capacity is corrected based on the material energy replenishment. Among them, the biocarrying capacity of the marine ranch is the maximum biomass that can sustain the survival of a population or group in the marine ranch area. In the Ecopath model, it can be expressed as the maximum biocarrying capacity level of a target population that has not significantly changed the main energy flow and food web structure of the ecosystem after a large number of biological functional groups are introduced, and then the aquaculture carrying capacity corresponding to the released species or farmed species is determined in the biocarrying capacity.

[0050] S50. Perform ecological management based on the aquaculture carrying capacity to obtain an ecological management strategy for the target marine ranch. In this embodiment, the maximum release rate and the maximum sustainable yield of the target marine ranch are evaluated based on the aquaculture carrying capacity, and an ecological management strategy is formulated based on the maximum release rate and the maximum sustainable yield.

[0051] Among them, the initial release strategy of the target species of the marine ranch is adjusted based on the aquaculture carrying capacity. Specifically, the maximum release density of the target species to be released is estimated based on the ecological capacity and survival rate of the target species to be released in the target marine ranch. The difference between the aquaculture carrying capacity and the existing population of the target species to be released is its release capacity. The total mortality rate and target weight of the target species to be released for reproduction are obtained based on the production research data, and the maximum reproduction density of the target species for reproduction is estimated accordingly.

[0052] In the present application, the initial release strategy of the target species to be released is determined based on the current ecological and environmental data such as the habitat suitability index of the target species in the target marine ranch, energy flow relationship data, and the ecological capacity of the target species. After the release is carried out according to the initial release strategy, the ecosystem evaluation results after the release and the ocean dynamic environment data during the growth cycle of the target species are obtained in real time to determine the dynamic ecological evaluation results based on the initial release strategy. Based on the dynamic ecological evaluation results, the Ecopath energy flow model is used to evaluate the aquaculture carrying capacity of the target marine ranch, and then a marine management strategy is constructed that can achieve both aquaculture (release) and ecological benefits.

[0053] In one embodiment, after each release, the effect of the current release is evaluated, and the next release strategy is adjusted based on the evaluation results, so that the release strategy of the target species is more and more reasonable through a cyclic adjustment. In this embodiment, the first actual ecological environment data after release at the maximum release rate is obtained; the second actual ecological environment data after fishing at the maximum sustainable yield is obtained; the first actual ecological environment data and the second actual ecological environment data are ecologically evaluated to determine the actual health status evaluation result and the actual ecosystem stability evaluation result of the target marine ranch. Specifically, the evaluation can be made with reference to the methods for health status evaluation and ecosystem stability evaluation in the above embodiments. The maximum release rate and the maximum sustainable yield are dynamically adjusted based on the actual health status evaluation results and the actual ecosystem stability evaluation results. In order to achieve the initial release strategy, ecological evaluation and biocapacity evaluation using the ecological environment data, energy flow data and marine dynamic environment data of the target marine ranch on the basis of the initial ecological management strategy, and adjust the initial ecological management strategy based on the evaluation results, thereby realizing a self-driven, self-discovered and self-evolving marine ranch ecology.

[0057] The first evaluation module 203 is used to obtain the ecosystem evaluation result of the target marine ranch after the initial release strategy is used, and to perform ecological evaluation on the target marine ranch of each target species in the growth cycle based on the ecosystem evaluation result and the marine dynamic environment data, so as to obtain the dynamic ecological evaluation result of the target marine ranch based on the initial release strategy;

[0058] The second evaluation module 204 is used to construct an Ecopath energy flow model corresponding to the target marine ranch using the plurality of target species as functional populations of the target marine ranch, and to evaluate the aquaculture carrying capacity based on the energy flow relationship data, the dynamic ecological evaluation results and the marine dynamic environment data using the Ecopath energy flow model to obtain the aquaculture carrying capacity of the target marine ranch;

[0059] The management strategy determination module 205 is used to perform ecological management based on the aquaculture carrying capacity to obtain an ecological management strategy for the target marine ranch.
