Embodiment 1

[0006] Embodiment 1: Adopt Macrobrachium rosenbergii overwintering pond, in the pool, Macrobrachium rosenbergii is stocked in a suitable place according to conventional density 20-25 tails / ㎡ and routine wintering management, nests the parents of goldfish in the pool, nests and raises density 2-3 tails / ㎡; Before putting in a suitable place to breed , the pool is filled with water, completely dissolved with 20ppm of bleaching powder, sprinkled over the whole pool, soaked for 2-3 days, drained, washed, and dried for more than 48 hours before use; place an inflatable head in the pool of 0.5-1 / ㎡, use The Roots blower is continuously inflated for 24 hours. The air volume is based on the uniform water splash on the water surface. The effective water level is 1m. The pool mouth is covered with a light-transmitting plastic film. From the local freshwater river, with a salinity of 1.7‰, it is used after the first-stage sedimentation in the pond and the second-stage sedimentation in the r...

Embodiment 2

[0007] Embodiment 2: adopt Macrobrachium rosenbergii overwintering pond, in the pool, Macrobrachium rosenbergii is stocked in a suitable place according to conventional density 20-25 tails / ㎡ and routine wintering management, nests and raises money fish fingerling in the pond, nests and breeds density 5-10 tails / ㎡; Put in a suitable place to breed Before, the pool is full of water, completely dissolved with 20ppm of bleaching powder, sprinkled on the whole pool, soaked for 2-3 days, drained, washed, and dried for more than 48 hours before use; place an inflatable head in the pool of 0.5-1 / ㎡, Use a Roots blower to continuously inflate air for 24 hours. The air volume is based on the uniform water splash on the water surface. The effective water level is 1m. The pool mouth is covered with a light-transmitting plastic film, which is mainly used for heat preservation and shading to create a quiet environment for fish and shrimp; It is taken from the local freshwater river with a sal...

Embodiment 3

[0008] Embodiment three: 20 square meters of rectangular cement ponds in the wintering shed using roof insulation boards, 1.2m deep; it is characterized in that before fish and shrimp are put, the cement pond is filled with water and then sprinkled with 20ppm bleach solution in the whole pond, soaked for 2-3 days Drain, wash and dry for more than 48 hours before adding water. The effective water level is 1m. 8-10 inflatable heads are placed in the pool, and the Roots blower is used to inflate continuously for 24 hours. 500 giant macrobrachium parents, 50-100 golden fish per pond; cover the pond mouth with light-transmitting plastic film; use fresh water throughout the process, control the temperature at 20-22°C, and manage the macrobrachium rosenbergii overwintering: measure the temperature once a day in the morning and evening, during the day Heating, the heating method is: hot water circulates in the "U"-shaped pipe at the bottom of each reservoir and the wintering pool; the ...

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 ...
