Static fish culture system

Abstract

The invention discloses a static fish culture system. The system comprises a closeable space, wherein an ambient temperature adjusting device, a square static fish pond and a fish pond oxygenation device are arranged in the closeable space; a temperature sensor and a water temperature adjusting device are arranged in the static fish pond, so that the water temperature in the fish pond is kept at 5-10 DEG C; the fish pond oxygenation device comprises an ozone oxygenation device and an air oxygenation device, the output end of the fish pond oxygenation device is connected with an oxygen deliverypipe vertically arranged downwards on the inner side wall of the fish pond, the oxygen delivery pipe is provided with a one-way valve I allowing flowing from top to bottom, the bottom end of the oxygen delivery pipe is connected with air distribution pipes provided with air holes, aeration discs are arranged at the air holes, at least five air distribution pipes are arranged and mutually communicated, four of the air distribution pipes are arranged on the inner side wall of the fish pond in a square shape, the other air distribution pipes are parallel and evenly distributed, and the two endsof the other air distribution pipes are vertically communicated with the opposite sides of the two parallel air distribution pipes. The system has simple structure, can provide a static environment for live fish to be sold, and can keep the live fish fresh and healthy.

Description

technical field [0001] The invention relates to the technical field of breeding equipment, in particular to a static fish farming system. Background technique [0002] Selling live fresh fish generally is that live fresh fish is put into fishpond and rests and waits to sell. The temperature and dissolved oxygen in the fish pond will directly affect the freshness and health of fresh fish, and affect the loss of fresh fish. The fresh fish sold in the market are generally freshwater fish such as grass carp, crucian carp, etc. Within a certain range, the fish are more active when the temperature is high, and they will stop eating and be quiet when the temperature is low, but the weight of the fish will be reduced if the temperature is too low. Generally, the suitable dissolved oxygen value for fish is above 3 mg / L. When the dissolved oxygen value in water is less than 3 mg / L, the fish will not eat and stop growing; when it is less than 2 mg / L, the fish will float their heads; ...

Problems solved by technology

The temperature and dissolved oxygen in the fish pond will directly affect the freshness and health of fresh fish, and affect the loss of fresh fish

The fresh fish sold in the market are generally freshwater fish such as grass carp and crucian carp. Within a certain range, when the temperature is high, the fish will be more active, and when the temperature is low, they will stop eating and be quieter, but if the temperature is too low, the fish will lose weight
