Method for breeding Australian freshwater lobsters

Abstract

The invention discloses a method for breeding Australian freshwater lobsters. The method is characterized by comprising the following steps of building a lobster pond, and selecting a place which is great in air circulation and free of pollution sources, faces the sun and has convenient irrigation and drainage conditions; cleaning and disinfecting the pond, wherein quick lime and water are used for cleaning the lobster pond, and the consumption of the mixture is 100 kg per mu; conducting stocking of young lobsters, wherein the specification of the young lobsters is 2-4 cm, and the density of stocking is 6,000-8,000 per mu; putting baits, wherein the baits are put once in the morning and evening every day, the feeding amount accounts for 5-10% of the weight of the lobsters, and the feedingamount in the evening accounts for 70-80% of the total feeding amount of the whole day; managing the lobster pond, wherein checking and patrols need to be carried out frequently at the ordinary time,and aquatic plants on the bottom of the pond are supplemented in time; conducting disease prevention and control, wherein prevention and control are carried out mainly, and disinfection of the body surfaces of lobster bodies is the most important work during disease prevention and control in order to prevent pathogens from being brought into the pond; checking whether or not purse nets around thepond are firm enough at the regular time; conducting harvesting, wherein stocking and harvesting are conducted in the same year. Lobsters bred according to the method are large in size, fat, rich in nutrient and high in growth speed, yield and survival rate.

Description

technical field [0001] The invention relates to a method for cultivating lobsters, in particular to a method for cultivating Australian freshwater lobsters. Background technique [0002] Australian freshwater lobster is native to Australia and lives in fresh water. It looks like a lobster in the sea, so it gets its name. Its body color is green or brownish green, and there is a bright red and soft membranous band on the outer side of the first claw of the male adult shrimp, which is extremely gorgeous. It is also called red claw shrimp and red claw shrimp. Originally a wild shrimp, artificial breeding began in 1971. It is currently one of the best freshwater shrimps in the world. [0003] In recent years, the Australian freshwater lobster farming industry has developed rapidly. However, the high-density farming model makes the ecosystem structure of the farming environment single and weak in resistance.

Problems solved by technology

[0003] In recent years, the Australian freshwater lobster farming industry has developed rapidly. However, the high-density farming model makes the ecosystem structure of the farming environment single and weak in resistance, which can easily lead to deterioration of water quality and frequent occurrence of shrimp diseases, which eventually lead to a large number of shrimp deaths and low survival rates.

In order to improve the survival rate, people use a lot of chemicals and antibiotics. Although the survival rate of shrimp has been improved to a certain extent, the negative effects of these drugs are also very obvious, not only changing the normal composition of shrimp intestinal flora, It leads to the imbalance of the micro-ecological environment in the intestinal tract, and also makes the drug remain in the organism, which hinders the healthy development of the pollution-free aquaculture industry
