High-density organic shrimp culturing technology

Abstract

A high-density organic shrimp culturing technology comprises the followings steps of (1) pouring water into a culturing pond, adding biological bacteria-resistant agent and starting an oxygen machine, (2) placing No.1 biological agent, No.2 biological agent and No.3 biological agent into the water, (3) extracting diatom water in the culturing pond to prepare a shrimp sprout test, (4) extracting diatom water in the culturing pond after salinity comparison is right and placing the shrimp sprouts into a container for 10 minutes to determine motility of the shrimp sprouts, (5) first opening a bottom culturing machine before the shrimp sprouts are placed into the culturing pond, then stopping the circulating oxygen machine, (6) feeding fodder for 15 days, (7) processing a spare culturing pond according to the (1) and (2) steps before developed seedlings are placed into the spare culturing pond, (8) after water processing, extracting diatom water in the spare culturing pond to prepare a shrimp sprout test to determine whether motility of the shrimp sprouts is normal after 10 minutes' preparing test and then placing the shrimp sprouts into the pond, (9) during developed seedlings culturing, maintaining the culturing water body between diatom water and green alga water, and at a long-term diatom water state. The fodder fed during the culturing is mainly wheat and beans for the first month and animal protein after the first month.

Description

technical field [0001] The invention belongs to the technical field of shrimp farming, and in particular relates to a high-density organic shrimp farming technology. Background technique [0002] In recent years, shrimp has become the aquaculture product with the most stable sales price in the aquaculture industry. As long as the farm receives a certain percentage of goods, it can make stable profits. In order to pursue profits, many farmers have continuously increased the amount of stocking in the breeding process. High-density breeding has caused farmers to face problems such as germ damage. Facing more germ problems, farms began to use drugs. During the breeding process, more than 200 kinds of drugs are used, including Chinese herbal medicines, chemicals, hormones and countless antibiotics. Every farm starts to use drugs to prevent or control germs from the first day of stocking. There are at least 20 kinds of drugs used in the harvest, so the harvested shrimp will have ...

Problems solved by technology

[0004] Whether it is medium-density or high-density farming, the traditional method of shrimp farming is to change a lot of water, use various drugs, antibiotics, hormones, high-protein feed, etc. These traditional methods will cause deterioration of the water environment. Drug treatment will eventually become the use of drugs to raise shrimps, and the cycle will turn into using drugs to raise viruses, and the viruses will undergo a large number of water changes to cause regional cross-infection, making it almost impossible to breed in many areas
