Culture method of lobsterling

Abstract

The invention discloses a culture method of lobsterling. The culture method includes the steps of 1), preparation of a culture pond; 2), treatment of the culture pond; 3), releasing of young seedlings; 4), feeding; 5), cooperative use of calcium supplement products; 6), capturing of adult lobsterling. Compared with the prior art, the culture method has the advantages that various links of the pond, seedling releasing quantity, water quality, capturing and the like are reasonably controlled, damage to the lobsterling by natural enemies, bacterial and the like can be reduced greatly, the survival rate of the lobsterling is high, high growth speed and high yield are achieved, and economic benefit is further improved; calcium is added in the shell-removing period, needs of the shell-removing period are supplemented, and slow production due to lack of the calcium is avoided; feeding amount and feeding time are arranged reasonably, and fodder is mainly fed in the afternoon; the fodder of thelobsterling is assuredly utilized maximumly, waste is avoided, and on the other hand, the fact that water quality is affected due to too much fodder left is avoided.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating crayfish. Background technique [0002] Crayfish are delicious due to various methods, and they are shuttled in the small streets of major cities, so the annual consumption is very large, so more and better quality crayfish is needed. During the growth process of crayfish, crayfish are often easily infected with diseases due to a large amount of feed. At the same time, due to the untimely cultivation of aquatic plants during breeding, a large amount of feed needs to be put in, resulting in a decline in the physical fitness of crayfish and prolonging the growth of crayfish. cycle, resulting in slower accumulation of crayfish meat, but also reduces economic benefits. [0003] For aquaculture species, especially crayfish species, the changes in growth form, the development of organs and tubes, and the regeneration of severed limbs must be completed thro...

And often and unreasonably put in calcium, can not meet the needs of lobsters, or cause a waste of calcium

[0004] Furthermore, because crayfish have a strong tolerance to polluted environments, in order to save farming costs, most farmers do not pay attention to the breeding environment of crayfish. Zinc, lead, cadmium and mercury exceed the standard by more than 150 times, and the crayfish itself has a strong ability to accumulate heavy metals, resulting in a large number of bacteria, parasites and heavy metals in the cultured crayfish, which do not meet the healthy food standards
