Sugpo prawn larva breeding method

Abstract

The invention discloses a sugpo prawn larva breeding method, which comprises the following steps of: (1) preparing bdellovibrio bacteriovorus plasma liquid; (2) pouring the bdellovibrio bacteriovorus plasma liquid into a nursery pond, wherein the bdellovibrio bacteriovorus plasma content of seawater is more than 101pfu/mL and aeration is carried out for 5 to 12h; (3) pouring the nauplius larvae of the sugpo prawns into the nursery pond at the density of 60,000 to 120,000/m<3>; and (4) regularly feeding bait into the nursery pond in a breeding process, and pouring the bdellovibrio bacteriovorus plasma liquid at the concentration of over 10pfu/mL into a nursery pond at an interval of at least 5 days every time after the nauplius larvae are poured into the nursery pond, wherein the young sugpo prawns can be obtained after the prawn larvae have been developed for 15 days or the body lengths of the prawn larvae are more than 1cm. In the invention, by water quality treatment and by pouring the bdellovibrio bacteriovorus plasma liquid into the bait and adopting scientific breeding management, the water exchange times during the breeding process can be effectively reduced and even water is not required to be exchanged, so that the yield of the young prawns is improved and the survival rate and immunity of the young prawns are improved.

Description

technical field [0001] The invention belongs to the technical field of prawn breeding and seedling cultivation, and relates to raising prawn seedlings of Penaeus monodon by using Bdellovibrio bructoria plastid liquid, so as to purify water quality, improve the breeding environment, improve the survival rate of seedling raising and the immunity of shrimp seedlings, and meet the requirements of energy saving and emission reduction Methods. Background technique [0002] Penaeus monodon (Penaeus monodon) is commonly known as ghost shrimp, grass shrimp, flower shrimp, bamboo prawn, monodon prawn, bovine prawn, and the Food and Agriculture Organization of the United Nations is commonly known as tiger prawn. Because of its strong adaptability, fast growth and large individual size, it has become an important breeding object in the world, ranking first in the production of farmed shrimp.

AI Technical Summary

Problems solved by technology

[0003] In the past ten years, the intensive and high-density Penaeus monodon aquaculture industry in my country has developed rapidly. However, with the expansion of the aquaculture scale, various problems have become increasingly serious, such as malnutrition, antibiotic abuse caused by increased diseases, and aquaculture water pollution. etc., have become the limiting factors for the sustainable development of the shrimp industry

In the process of raising Penaeus monodon seedlings, larval diseases often occur. In recent years, due to environmental pollution in the sea area and unstable water quality near the shore, the breeding of Penaeus monodon often results in large-scale production reduction due to outbreaks of shrimp diseases.
