Method for improving environment of penaeus penicillatus nursery pond

Abstract

The invention discloses a method for improving the environment of a penaeus penicillatus nursery pond and belongs to the technical field of fishery. The method comprises the following steps of 1) preparing an environment improver, namely uniformly mixing 4 to 9 parts of cellulose, 5 to 10 parts of protease, 20 to 30 parts of bacillus subtilis, 10 to 20 parts of bifidobacterium, 40 to 50 parts of fresh willow leaf powder, 5 to 10 parts of sodium bromide and 3 to 8 parts of calcium peroxide, wherein the fresh willow leaf powder is prepared by drying and crushing fresh willow leaves; 2) binding fresh willow twigs into bundles, putting the bundles onto the bottom of the nursery pond, and replacing once every month; 3) scattering the environment improver into the nursery pond in a using amount of 1-2kg of environment improver in 30-60 cubic meters of nursery pond, and scattering 2-3 times every month. According to the method for improving the environment of the penaeus penicillatus nursery pond, growth and propagation of pathogenic microorganisms are prohibited, the ecological environment of aquatic water is quickly restored, diseases and sudden death of penaeus penicillatus are effectively prevented, and the yield and the quality of the penaeus penicillatus are improved.

Description

technical field [0001] The invention belongs to the technical field of fishery, and in particular relates to an environment improvement method for nursery ponds of Penaeus villosa. Background technique [0002] The water quality at the bottom of the penaeus villosa nursery pond is prone to deterioration due to the deposition of organic matter, which often causes hypoxia and affects the survival of cultured animals at the bottom, especially for benthic cultured animals such as shrimp and crabs. The bottom of the pond is the main living place, and harmful substances at the bottom of the pond Accumulation often leads to the fleeing and even death of the long-haired prawns; traditional methods such as changing water and increasing oxygen have poor effect on improving the water quality environment at the bottom of the pond. Microbial preparations are generally splashed on the water surface and cannot reach the bottom of the pond. The improvement effect of the environment is not v...
