Dry land fish culture system

Abstract

The invention discloses a dry land fish culture system which comprises a dry land pond, a green fodder planting pond and a clean water pond. The green fodder planting pond is communicated with the dry land pond, and the clean water pond is communicated with the green fodder planting pond. The water in the clean water pond flows to the dry land pond, the water in the dry land pond flows to the green fodder planting pond, the water in the green fodder pond flows to the clean water pond, and water circulation is formed. The dry land fish culture system has the advantages that the system is fast in water change, less prone to bacterial reproduction, low in ammonia and nitrogen content and high in dissolved oxygen amount in the water, the water flows continuously, and growth of grass carp is benefited; the system can be built on dry land and unrestricted by strict natural conditions; the system is low in total required fish culture water amount and worthy of popularization.

Description

technical field [0001] The invention relates to the field of fish farming systems, in particular to a dryland fish farming system. Background technique [0002] Grass carp has a simple feeding habit, a wide range of bait sources, rapid growth, high yield, fat and tender meat, and delicious taste. It is often used as the main stocking object for pond farming and lakes, reservoirs, and rivers. Since 1958, when the technology of artificial induced labor and fertilization and hatching was successful, the source of fry and fingerlings is easy, and it has become the main intensive breeding target in my country. For high-density grass carp intensive culture ponds, the main thing is to maintain good and stable water quality, and focus on preventing anoxic flooding and preventing fish bodies from being injured by net fishing. [0003] As the saying goes, fish first raises water! Raising good water quality is a necessary condition for raising good fish. In the traditional fish farm...

AI Technical Summary

Problems solved by technology

In the traditional fish farming method, the water in the pond takes a long time to change, and a variety of bacteria multiply in the water, which leads to the water quality is easy to deteriorate. Grass carp grows in such water quality and it is easy to get sick, which ultimately affects the production.

In addition, traditional fish farming methods rely on specific natural conditions such as lakes, rivers, reservoirs, ponds, etc., and have low yields

The water used in the traditional fish farming method is mixed with a large amount of fish feed and fish feces, which will lead to a rapid increase in the ammonia nitrogen content in the water, which is not conducive to the growth of grass carp. If it is directly discharged, it will pollute the external water source

[0004] At present, grass carp weighing more than 8 catties is in short supply all over the country, and traditional fish farming methods are difficult to breed successfully on a large scale, resulting in a shortage in the market and unable to meet people's daily needs
