Scatophagus argus and macrobrachium rosenbergii intercropping overwintering mode

Abstract

The invention relates to a scatophagus argus and macrobrachium rosenbergii intercropping overwintering mode. The scatophagus argus and macrobrachium rosenbergii intercropping overwintering mode adopts a macrobrachium rosenbergii overwintering pond and is characterized in that scatophagus argus is intercropped in the pond; before stocking, the interior of the pond is washed and cleaned; an inflation head is placed in the pond for continuously inflating, effective water level is 1m, and a transparent plastic film covers the entrance of the pond; fresh water is adopted, subjected to primary precipitation by virtue of the pond and secondary precipitation by virtue of a reservoir and preheated and then is applied in the pond; a circular heating hot water pipe is also paved at the bottom of the overwintering pond, a water inlet pipe in the pond is sheathed by a 60-mesh bolting silk mesh for filtering, water is changed every 7-10 days, water changing temperature difference is controlled to be + / -1 DEG C, temperature is controlled to be 20-22 DEG C and synchronously raised at a rate of 0.5 DEG C per day before breeding of macrobrachium rosenbergii, the temperature is stabilized for 15-20 days when the temperature is raised to 25 DEG C, and then the temperature is raised for a second time until the temperature is raised to 29 DEG C; the pond is reversed once every month; bait is thrown once in the morning and evening respectively, compound bait is adopted for feeding in the morning, fresh and alive trash fish meat paste or snail meat is used for feeding in the evening, and a scatophagus argus extruded feed is supplemented; and pollution is absorbed once everyday, and water quality indexes comprise that dissolved oxygen is more than 5mg / L and pH value is 7.5-8.5.

Description

technical field [0001] The invention relates to the overwintering culture of money fish, in particular to the technology of using Macrobrachium rosenbergii to nest and raise money fish in overwintering ponds to solve the problem of money fish overwintering. Background technique [0002] Money fish (Scatophagus argus), commonly known as golden drum fish, belongs to Perciformes, Perciformes, Scatophagidae and Scatophagus. It is an omnivorous fish that likes to eat algae, organic debris, arthropods and Small fish and other fresh bait, the adult fish body length is about 30cm, native to the brackish and fresh water of river estuaries in Indonesia, the Philippines, Thailand and other places, also found in the estuaries of rivers in southern my country, because of its beautiful shape and color It is beautiful, gentle in temperament and delicious in meat quality. It is a rare seawater economic fish with ornamental and edible value. It can be cultured in seawater, brackish water and ...

AI Technical Summary

Problems solved by technology

The suitable temperature range of money fish is 16-40°C. If the temperature is lower than 12°C, it will start to die. Therefore, to promote the breeding of this fish in the surrounding areas of Shanghai, we must consider the supporting facilities for overwintering, and independent heating and overwintering equipment will waste energy and water quality. The utilization rate is not high, the parasitic diseases such as small melon worms are easy to occur, and frequent medicinal bath treatment is required, and the cost of overwintering is high.
