Low-cost and high-efficiency aristichthys nobilis pond culture method using plankton for feeding

Abstract

The invention provides a low-cost and high-efficiency aristichthys nobilis pond culture method with plankton for feeding, which comprises the following steps: by adopting a pond main culture mode of aristichthys nobilis, intercepting a 1 / 3 water surface in the pond by using a net to specially serve as a breeding and culturing area of plankton, separating an aristichthys nobilis culture area from a plankton breeding area, and separating the aristichthys nobilis culture area from the plankton breeding area; the breeding capacity of the zooplanktons is greatly improved, the zooplanktons can continuously flow to the bighead carp breeding area through the meshes to be ingested by the bighead carps when reaching a certain density, organic fertilizer is frequently applied to the plankton breeding and culturing area, the quantity of the planktons is continuously bred to the maximum extent, and therefore the yield of the bighead carps is increased; the water quality is regulated and controlled through methods such as a microbial preparation and the like, so that space bacterial phase balance and excellent water quality for fish survival are ensured, fish diseases are reduced, meanwhile, water body exchange is reduced, water sources are saved, pollution emission and energy consumption are reduced, and the quality of commercial fish is improved.

Description

technical field [0001] The invention relates to the field of pond culture of bighead carp, in particular to a low-cost and high-efficiency method for cultivating bighead carp in a pond fed by plankton. Background technique [0002] In recent years, the price of grass carp has continued to slump, the cost of feed is high, the efficiency of farming is low, and even losses have caused loss of confidence in grass carp farming, while the price of bighead carp has risen steadily in recent years. Secondly, in recent years, lakes, reservoirs, rivers, etc. Fish farming has been banned in the local area, and the production of bighead carp has dropped significantly, resulting in a shortage of bighead carp in the market and high prices. However, there are some shortcomings in the existing bighead carp breeding process that need to be innovated. The first is the growth rate of bighead carp. Fast, with natural plankton as food, but in the process of the existing bighead carp pond culture ...

[0002] In recent years, the price of grass carp has continued to slump, the cost of feed is high, the efficiency of farming is low, and even losses have caused loss of confidence in grass carp farming, while the price of bighead carp has risen steadily in recent years. Secondly, in recent years, lakes, reservoirs, rivers, etc. Fish farming has been banned in the local area, and the output of bighead carp has dropped significantly, resulting in a shortage of bighead carp in the market and high prices. However, there are some shortcomings in the existing bighead carp breeding process that need to be innovated. The first is the growth rate of bighead carp. Fast, with natural plankton as food, but in the process of the existing bighead carp pond culture method, the plankton is quickly preyed on by the bighead carp in the pond, which leads to the inability of the plankton to reproduce sustainably and quickly , resulting in the lack of food and slow growth of bighead carp in aquaculture. Therefore, we have made innovations and proposed a low-cost and high-efficiency method of feeding bighead carp with plankton in ponds
