The invention discloses a coreius coreius intensive cultivation method based on interspecific competition. The method comprises the following steps: S1, setting an industrial running water cultivation environment; s2, selection and stocking of coreius gigas parents; S3, domestication of the coreius gigas parents; s4, artificial feed selection and adaptation; s5, introducing bottom exogenous species such as myxocyprinus asiaticus to remove residual feed; s6, cold water slow ingestion type fishes such as acipenser schrenckii are introduced; and S7, water temperature rising control. By accurately controlling the culture environment, introducing bottom-layer species such as myxocyprinus asiaticus to remove residual feed and introducing cold water fishes such as acipenser schrenckii, the inter-species competition pressure is increased, the food snatching desire of coreius guichenoti parents is promoted, nutrition intake is increased, gonad development is promoted, meanwhile, a good ecological system is formed, the sustainability of the whole system is enhanced, and the survival rate of coreius guichenoti is increased. According to the comprehensive advantages in coreius guichenoti parent cultivation, the cultivation efficiency and economic benefits are improved, ecological balance and sustainable development can be achieved, and powerful support is provided for future aquaculture.

A method for cave cultivation of procambarus clarkia seedlings, comprising the following steps: rice field selection, rice planting, parent shrimp preparation before stocking, parent shrimp stocking, parent shrimp cultivation, stress cave digging and cave entering, field drying, rice harvesting, rice stubble green-up, cave cultivation, induced cave exiting and cage catching; wherein the rice field selection is to select a rice field with sufficient water source and convenient irrigation and drainage, the relative two sides of the field have height difference, the field ridge is reinforced and has a mouse, frog and snake prevention iron fence, and a polyethylene net is surrounded along the inner side of the field ridge; the parent shrimp stocking is to stock female parent shrimp with ovary maturity of stage III, and the female to male ratio is 1:1; the parent shrimp cultivation comprises feed feeding, water quality control and daily management; the stress cave digging and cave entering is to drain water; the rice harvesting is after the field drying; the rice stubble green-up is to keep shallow water to promote growth after the rice harvesting until new grass seedlings are generated; the cave cultivation is to regularly pour horse race water rich in food; and the induced cave exiting is to induce by water injection and feed feeding. The cave cultivation method can improve the survival rate of the seedlings and the parent shrimp.

The invention belongs to the technical field of fish and soft-shelled turtle polyculture control, and discloses a fish and soft-shelled turtle polyculture stocking parameter determination method and device. The determination method comprises the following steps: firstly, obtaining a culture target label of fish and turtle polyculture and corresponding historical stocking parameters; screening stocking parameter information corresponding to each breeding target label, and constructing a linear prediction model and a nonlinear prediction model corresponding to each breeding target label; further optimizing to obtain an optimized prediction model; and when a breeding target instruction input by a user is received, analyzing the breeding target instruction to determine a corresponding breeding optimization target and optimization prediction model so as to output optimized stocking parameters corresponding to the breeding target instruction. According to the determination method, key stocking parameters of economic benefits and ecological effects of fish and turtle polyculture can be accurately determined, great significance is achieved for reducing the culture cost and improving the culture benefits, and meanwhile optimization of the internal structure of a culture system, reduction of carbon emission and formation of a healthy and low-consumption ecological culture mode are facilitated.

The utility model relates to the technical field of ecological stocking of aquatic animals, in particular to an ecological river and lake gastropod three-dimensional stocking structure and a stocking method. The stocking structure comprises a spiral fixing base and is composed of a spiral structure, a top cover, a base and a feeding channel, the feeding channel is formed in the axial center of the spiral structure, a plurality of holes are formed in the peripheral wall of the feeding channel and communicated with the spiral structure, and the two ends of the feeding channel are detachably connected with the top cover and the base respectively; the plurality of spiral fixing bases can be transversely or longitudinally spliced and combined; and the mesh enclosure is detachably mounted on the periphery of the spiral fixing base and wraps the spiral structure. The stocking structure is suitable for most ecological rivers and lakes, the detachable structure is convenient to use, and the activity space of the gastropods is increased. Through scientific structural design, stocking site selection and daily management, efficient and eco-friendly gastropod stocking is achieved, and sustainable development of species resource quantity recovery and ecological restoration is achieved.

This invention discloses a factory-scale recirculating aquaculture system (RAS) for the large-spined loach. The method specifically includes the following aspects: selection and pretreatment of the rearing pond, arrangement of habitat units, setting up feeding facilities, operation of the recirculating aquaculture system, and stocking and management of fry. The habitat unit consists of large-diameter and small-diameter pipes; multiple small-diameter pipes are evenly placed and fixed within each large-diameter pipe, with the axis of the small-diameter pipes parallel to the axis of the large-diameter pipes. The feeding facilities consist of multiple liftable feeding platforms evenly placed along the wall of a 6m diameter land-based circular rearing pond. This factory-scale RAS method, which provides a suitable habitat for the large-spined loach, adapts to its feeding habits, optimizes recirculating aquaculture system operating parameters, quantifies rearing density, and manages feeding, has significant practical implications and promotional value for overcoming the technical bottlenecks in large-scale large-spined loach farming and promoting the sustainable development of the industry.
