Description

Technical Field

[0001] The present invention relates to the technical field of fish shape and weight, and particularly relates to a portable method and system for collecting fish shape and weight information. Background Art

[0002] In the research of fishery resources, scientific researchers also need a large amount of accurate fish shape and weight data for population structure analysis, ecosystem assessment, and the formulation of species protection strategies. However, the existing fish information collection methods have significant defects. Traditional manual measurement methods, such as using a ruler to measure body length and a caliper to measure body width, are not only cumbersome and inefficient but also prone to measurement errors due to human operation. Especially when measuring fish with irregular shapes, the errors are more obvious. Therefore, it is necessary to analyze a portable method and system for collecting fish shape and weight information.

[0003] The prior art, such as an invention patent application with the publication number of CN116862417A, discloses an Internet of Things-based aquaculture monitoring system. Water quality is one of the key factors for successful aquaculture. In aquaculture, measuring the water quality of a single layer cannot control the water quality of the entire farm. This invention divides the water area and detects the water quality at different depth layers, greatly improving the accuracy and reliability of the water quality detection results, and thus being more conducive to water quality regulation, providing a reliable basis for subsequent aquaculture.

[0004] The prior art for a portable method and system for collecting fish shape and weight information can meet the basic requirements, but there are also some potential defects and challenges, which are specifically reflected in the following aspects: First, in the prior art, the analysis of the growth compliance index of the shape of each fish in the aquaculture area and the growth compliance index of the weight of each fish in the aquaculture area is not deep enough. Without understanding the growth laws of fish shape and weight, it is difficult to judge whether the breeding density is appropriate. If the density is too high, the activity space of fish is limited, the growth rate slows down, and the risk of disease transmission increases. If the density is too low, the breeding space is wasted, the breeding output is reduced, the goodness of the fish growth environment is reduced, the breeding loss is increased, and the lack of timely corresponding treatment measures leads to the spread of diseases and pollution of water quality, which is not conducive to the healthy growth and development of fish.

[0005] Second, the attention to the growth status index of each fish in the aquaculture area is not high, and the judgment of whether the growth status of each fish is abnormal is lacking. As a result, the accuracy of the survival environment index of each fish in the aquaculture area is reduced, affecting the environment for fish growth, and thus affecting the creation of more suitable survival and growth conditions for fish, inhibiting fish growth, reducing the breeding output and quality, further affecting the breeding environment, increasing the problems of slow growth or death of fish caused by unsuitable environment, and increasing the breeding cost. Summary of the Invention

[0006] The object of the present invention is to provide a portable method and system for collecting fish shape and weight information, which solves the problems existing in the background technology.

[0012] Furthermore, the shape growth compliance index of each fish in the aquaculture area is as follows. The specific analysis method is: Based on the obtained shape data of each fish in the aquaculture area, where the shape data includes the spinal curvature deviation value, the number of scale shedding, the amount of mucus, and the gloss value at each growth stage, and extracting from the database the compliance value range of spinal curvature, the compliance range of the number of scale shedding, the compliance range of the amount of mucus, and the compliance value range of gloss for each growth stage of each fish in the aquaculture area, and then analyzing the shape growth compliance index of each fish in the aquaculture area.

[0015] Furthermore, for the spatial influence value of each fish in the aquaculture area, the specific analysis method is as follows: Based on the obtained survival space data of each fish in the aquaculture area, where the spatial data includes: the breeding density of each fish, extract the appropriate breeding density difference of each fish from the database, perform a difference process on the breeding density of each fish in the aquaculture area to obtain the breeding density difference of each fish in the aquaculture area, and analyze the spatial influence value of each fish in the aquaculture area.

[0017] Furthermore, for the growth state index of each fish in the aquaculture area, the specific calculation formula is:

[0018] Furthermore, for judging whether the growth state of each fish is abnormal, the specific analysis method is as follows: Based on the obtained growth state index of each fish in the aquaculture area, compare the growth state index of each fish in the aquaculture area with the growth state index threshold of each fish in the aquaculture area extracted from the database. If the growth state index of a certain fish in the aquaculture area is less than the growth state index threshold of each fish in the aquaculture area, it indicates that the growth state of this fish is in an abnormal state, and the survival environment data of each fish is collected , denoted as the The growth anomaly status data of fish The safety interval of growth anomaly status data of fish in the aquaculture area .

When the survival environment index of each fish in the aquaculture area is greater than or equal to the survival environment index threshold of each fish in the aquaculture area, the fish in the aquaculture area is recorded as each normal fish.

A method for collecting information on the shape and weight of portable fish, characterized in that, The specific analysis method for evaluating the living environment index of various fish in the aquaculture area and performing environmental improvement processing is as follows: Based on the obtained survival environment data of each fish species, where the survival environment data includes feeding frequency, planktonic times, and gill filament integrity value, and extracting from the database the intervals that the feeding frequency, planktonic times, and gill filament integrity value of each fish species in the aquaculture area conform to, and then analyzing the survival environment index of each fish species in the aquaculture area, and its specific calculation formula is: , Denoted as the th growth anomaly data of the th fish species in the aquaculture area, Denoted as the safety interval of the th growth anomaly data in the aquaculture area, ; When the survival environment index of each fish in the aquaculture area is less than the survival environment index threshold of each fish in the aquaculture area, the fish in the aquaculture area is recorded as each risk fish, and the set of each risk fish in the aquaculture area is obtained through analysis. When the survival environment index of each fish in the aquaculture area is greater than or equal to the survival environment index threshold of each fish in the aquaculture area, the fish in the aquaculture area is recorded as each normal fish. When the shape growth compliance index of each fish in the aquaculture area is -1, the fish in the aquaculture area is recorded as each normal fish, and the set of each normal fish in the aquaculture area is obtained through analysis; Extract the set of suitable regulated water environment indicators for each risk fish set and each normal fish set in the aquaculture area from the database, and predict the set of water environment regulation parameters in the aquaculture area. Among them, the set of water environment regulation parameters includes the regulation intervals of each water environment indicator.

10. A system for implementing a portable fish shape and weight information acquisition method according to any one of claims 1-9, characterized in that, Including: Shape measurement and analysis module: Record the three-dimensional shapes of each fish in the aquaculture area through a depth camera, use image analysis software to import the images of each fish collected, and through the measurement tools in the software, combined with the scale on the background board, identify each stage of each fish in the aquaculture area to obtain the shape data of each fish in the aquaculture area, and then analyze the shape growth compliance index of each fish in the aquaculture area; Weight collection and analysis module: Record the weights of each fish in the aquaculture area through a weighing system, and obtain the weight influence data of each fish in the aquaculture area through a detection platform, and then evaluate the weight growth compliance index of each fish in the aquaculture area; Data processing module: Based on the obtained shape growth compliance index of each fish in the aquaculture area and the weight growth compliance index of each fish in the aquaculture area, evaluate the growth state index of each fish in the aquaculture area, and judge whether the growth state of each fish is abnormal. If it is abnormal, obtain the growth abnormality condition data of each fish, evaluate the survival environment index of each fish in the aquaculture area, and perform environmental improvement processing.
