Running water fish culture system

Abstract

The invention discloses a running water fish culture system. The system comprises a running water fish culture unit, a manure waste conversion fertilizer preparation unit and a tail water environmental protection control unit, wherein fish manure and residual feed can be converted into an organic agricultural fertilizer through the manure waste conversion fertilizer preparation unit and the tail water environmental protection control unit, and culture tail water is purified and converted into clean water suitable for culture to return to the system for recycle, thereby increasing the recyclingrate of manure waste and tail water to improve the environmental protection property of fish culture and reduce the culture cost. Moreover, the running water fish culture unit can achieve no-dead-angle manure removing, no-dead-angle water changing, no-dead-angle heating, no-dead-angle PH value adjustment, no-dead-angle aeration and no-dead-angle medicine mixing of a pool body by arranging a manure waste removing mechanism, a water exchange mechanism, a water temperature adjustment mechanism, a pH value adjustment mechanism, a dissolved oxygen amount adjustment mechanism, a medicine mixing mechanism, a feed spreading mechanism and an adult fish harvesting mechanism, the fish culture environment is comprehensively controlled, and the yield of fish culture is increased.

Description

technical field [0001] The invention relates to the technical fields of aquaculture and environmental protection, and more specifically relates to a living water fish farming system, which is suitable for high-density living water culture of freshwater fish and sea fish. Background technique [0002] Fish is an indispensable and important food material in people's life. Natural raw fish can no longer meet the daily needs of people's life. Artificial breeding has become the main way for human beings to obtain fish food. Among them, the proportion of living water and high-density freshwater fish farming (including seawater) in the production capacity of the same industry is increasing, showing a trend towards large-scale, intensive, systematic and industrialized farming. With progress, the quality of farmed fish will be better and better, production costs will be lower and lower, environmental hazards will be smaller and smaller, and the proportion of production capacity will ...

AI Technical Summary

Problems solved by technology

[0004] ① Serious environmental pollution: part of the fish feces and residual feed produced by high-density fish farming in traditional ponds, ponds, and cages are taken away by running water, and most of them sink to the bottom. Environmental water body

[0005] ② No water temperature control function: The growth of various fish species has different requirements for the temperature of the aquaculture water body. The water body temperature is an important condition for determining the breeding cycle, feed amount and disease degree. However, the existing process schemes generally have no water body temperature adjustment mechanism;

[0006] ③No dissolved oxygen control function: The dissolved oxygen content in water is the basic condition for fish growth, and the existing technology generally uses air compression type and mechanical impact type oxygenator to oxygenate, which cannot fundamentally solve the dissolved oxygen content in ponds and ponds. and uniformity issues;

[0007] ④ No pH control function: The growth of various fish species has different requirements for the pH of the cultured water. The pH of the water is an important condition for determining the breeding cycle, feed amount and disease degree. The existing process generally adopts simple methods such as spraying lime powder Adjustment, there is no complete and efficient water pH adjustment mechanism;

[0008] ⑤ High cost of breeding: fish feces, residual feed fermentation, and mildew lead to deterioration of the water body environment, which is the main cause of fish disease and death. At the same time, a large number of prevention and treatment drugs further deteriorate the water body environment. Increased cycle time, increased feeding volume, increased feed costs and drug costs;

[0009] ⑥ No drug mixing mechanism: In the process of fish farming, a certain amount of disease prevention and treatment drugs will be applied according to the situation, while the traditional technology dilutes the drugs with water and sprinkles them directly on the surface of the aquaculture water body, and slowly merges with the water body without dispersing High concentration potions of are very harmful to fish and ineffective
