AI Technical Summary

Problems solved by technology

However, due to the lack of systematic and in-depth work of research institutes and bait manufacturers in the development of low salinity, autumn and winter Litopenaeus vannamei baits, most of the current Litopenaeus vannamei baits used by farmers cannot meet the requirements of low salinity, autumn and winter breeding. The physiological and nutritional requirements of Litopenaeus vannamei under different conditions, the market lacks a special bait suitable for low-salinity, autumn and winter culture of Litopenaeus vannamei
Moreover, under the condition of completely relying on the existing bait, only 30-40% of the total bait fed is used to increase the body weight of Litopenaeus vannamei, and the rest is discharged into the water in the form of excrement, residual bait or feces , leading to serious pollution of the breeding itself, and the fertilizers, disinfectants, antibiotics and other drugs put in during the breeding process also aggravated the self-pollution of the farming, which became a bottleneck affecting the upgrading of low-salinity culture of Litopenaeus vannamei

Abstract

The invention relates to an ecological bait for the low salinity ecological cultivation of Lito penaeus vannamei in autumn and winter, which is prepared from the following raw materials (by weight ratio): basic nourishing constituents 85-95%, pharmaceutical constituents 1-5%, enzyme constituents 3-10%. The invention also provides the process for preparing the bait.

Description

technical field [0001] The invention relates to a breeding bait, in particular to an ecological bait suitable for the cultivation of Litopenaeus vannamei in low-salinity autumn and winter. The invention also relates to a preparation method of the ecological bait. Background technique [0002] In recent years, due to the deteriorating coastal aquaculture environment, frequent outbreaks of Litopenaeus vannamei farming diseases; many scholars believe that low-salinity culture of Litopenaeus vannamei is not only an effective method to control outbreaks of epidemic diseases, but also effectively utilizes salinization. Therefore, culture of Litopenaeus vannamei in low-salinity water ponds has become popular in many countries. However, in some parts of northern my country, due to seasonal changes or unstable weather in nature, they often encounter irregular or / and long-term low temperatures, which often make the cultured Litopenaeus vannamei, especially the low-salinity cultured V...
