Problems solved by technology

This approach mainly has two disadvantages: one, it is easy to cause adverse effects on the external water environment
Our city is located on the shore of Taihu Lake and Gehu Lake. Most of the water intake or drainage of fish ponds come directly or indirectly from the above two lakes. Sustained and Healthy Development of Aquatic Industry in Our City
2. The taste of commercial fish is not good
There are three reasons for the poor taste: first, the pond water quality is poor, ammonia nitrogen, nitrite, and toxic and harmful algae and other substances are high, and the commercial fish sludge produced has a strong fishy smell, which affects consumer demand; second, the whole process Pellet feed is fed, and the structure of the feed variety is too single, which leads to unsavory taste; third, in order to reduce the cost of breeding and increase the rate of return on bait, most farmers do not implement the regulations on the repair period of fish medicines, and they are ready to market at any time, let alone before the market. Slimming treatment is adopted, resulting in loose meat and poor taste of commercial fish

Embodiment Construction

[0019] The invention provides a method for producing high-quality long-breasted catfish based on ecological simulation, comprising the following steps:

[0020] (a) Pond selection: build a rectangular or square fish pond with an area of ​​8-10 mu and a water depth of 2-2.5m. The pond is regular and the bottom of the pond is flat. It has water inlet and drainage facilities and is equipped with 1 cultivator and 2-3 submersible pumps. ;

[0021] (b) Environmental simulation: According to the hydrological characteristics of the middle and lower reaches of the Yangtze River, simulate the similar ecological environment of the natural waters of the Yangtze River, rationally adjust and gradually transform, so that the cultured species can gradually adapt to the environment;

[0022] (c) Stocking: Select seedlings from the same source for stocking, and the selected seedlings are neat in size, strong in physique, bright in color, healthy and lively, free of disease, injury, and parasite...

Abstract

The invention provides a method of producing a high-quality long-snout catfish based on ecological simulation, which comprises the following specific steps of pond selection, environment simulation, stocking, field training, aquaculture management, and fishing and coming to the market. Through adopting the above method, a role of enhancing the quality of the long-snout catfish is played, environmental safety is ensured, consumption needs are met, and high economic benefits can also be obtained.

Description

technical field [0001] The patent of the present invention relates to the technical field of agricultural aquaculture, in particular to a method for producing high-quality long-snout catfish based on ecological simulation. Background technique [0002] As the costs of pond rent, feed, and labor increase, most farmers usually adopt high-density intensive farming and feeding a large amount of artificial compound feed to obtain high yield and high efficiency in order to maintain the efficiency of farming. This approach mainly has two disadvantages: one, it is easy to cause adverse effects on the external water environment. In recent years, the country, provinces and cities have intensified their efforts in water environment governance, banned and shut down many high-polluting enterprises, and dealt with a considerable number of relevant responsible persons. Our city is located on the shore of Taihu Lake and Gehu Lake. Most of the water intake or drainage of fish ponds come dir...
