Problems solved by technology

[0004] At present, the taste of tilapia fed with artificial concentrated feed is worse than that of naturally grown fish, with loose meat and reduced umami taste, while fish fed with pure green feed has a longer growth cycle and cannot meet market demand
When tilapia is raised alone, the species is single, the pond space and bait are not fully utilized, and the efficiency is low. When it is mixed, it is necessary to choose a reasonable species and quantity, which is in line with the ecological cycle of the pond.

Abstract

The invention discloses an efficient fish-shrimp mixed cultivation method using strain feeding. The method includes the steps of firstly, performing Infrastructure preparation and pond cleaning and preparation; secondly, cultivating water; thirdly, adding fish fry and shrimp seeds; fourthly, feeding bait; fifthly harvesting. The method has the advantages that the strain feeding of the pond water is improved by strain feeding, pond space and bait utilization rate are increased, and high cultivation condition controllability and cultivation procedure standardization are achieved; extremely higheconomic benefits are increased, the survival rate of fish cultivated by the method reaches up to more than 86%, shrimp survival rate reaches up to more than 82%, and the net benefit of the fish and shrimps reaches up to 15000yuan / mu.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-efficiency fish and shrimp polyculture method for strain support. Background technique [0002] Tilapia is commonly known as Nanyang crucian carp, African crucian carp, non-crucian carp, Vietnamese fish, Nanyang crucian carp, etc. Originally refers to the species of Oreochromis mossambicus with Mozambique as the model place of origin: Mozambique Oreochromis mossambicus (scientific name: Oreochromis mossambicus), now it is the genera of Oreochromis and Oreochromis in the family Cichlidae. The common common name; in English, it is collectively called Tilapia. Now it is a freshwater farmed fish cultivated by key scientific research in the world's aquaculture industry, and it is known as one of the main sources of animal protein in the future. They usually live in fresh water, but can also live in salt water with different salinity content, and can also survive in shallo...
