Ecological breeding method for mixed breeding of gold saddle rabbitfish and giant freshwater prawns

Abstract

The invention relates to an ecological breeding method for mixed breeding of gold saddle rabbitfish and giant freshwater prawns. The ecological breeding method comprises the steps that 1, pond cleaning is performed before water inflowing, pond drying in the sun is performed for 14-16 days, and then water inflowing begins, wherein the salinity of a water body is 3-8; 2, the gold saddle rabbitfish and the giant freshwater prawns are bred in a breeding pond in a mixed mode, wherein the density of the gold saddle rabbitfish is 2500-2600 per mu, and the density of the giant freshwater prawns is 50000-5200p per mu; a seawater floating mixed feed and a giant freshwater prawn feed are fed respectively every day in month before the breeding process; only the seawater floating mixed feed is fed after one month of breeding. By adopting the breeding method, the gold saddle rabbitfish survival rate can be up to 85%, the yield of the gold saddle rabbitfish per mu is up to 192 kg, the yield of the giant freshwater prawn per mu is up to 200 kg, bred giant freshwater prawns are large and few get ill, a breeding effect is remarkable, and the ecological breeding method has a good application prospect.

Description

technical field

[0001] The invention belongs to the field of aquaculture, and in particular relates to an ecological culture method for polyculture of S. rosenbergii and Macrobrachium rosenbergii. Background technique

[0002] Dianbasketfish is a rare marine omnivorous fish with delicious meat, high protein content, and rich polyunsaturated fatty acids, which is deeply loved by consumers. Point basket fish has strong adaptability and strong tolerance to salinity and temperature, and can be cultured in most areas south of the Yangtze River in my country. After a certain degree of salinity domestication, the basketfish can also be cultured in brackish water. Basket fish likes to eat large algae such as prolifera. It has a mixed diet and a short food chain, which can reduce the investment in aquaculture, which is conducive to the improvement of the breeding environment. Sustained development has far-reaching significance. my country has carried out aquaculture of dangling fi...

Embodiment 1

[0016] (1) The breeding pond is an earthen pond of 2 mu, and each pond is equipped with an impeller aerator with a power of 3KW. Before entering the water, use 20 catties of bleaching powder to clear the pond. After 15 days of drying, the pond starts to enter the water. The water source is the filtered water from the outer pond, and the salinity of the water body is 3-8.

[0017] (2) Polyculture of S. rosenbergii and Macrobrachium rosenbergii with an initial body length of 4.16 cm was carried out in the breeding pond. Feed seawater floating compound feed and Macrobrachium rosenbergii shrimp feed every day for a month, respectively, at 6:00 in the morning and 16:00 in the afternoon. The daily feeding amount is 5% of the respective body weight of the fish and shrimp, and the feeding situation is observed. Increase or decrease in moderation according to the eating situation. After one month of breeding, only seawater floating compound feed was fed, which were fed at 6:00 in the ...
