Problems solved by technology

[0003] However, the winter is dominated by cloudy weather, the photosynthesis of algae is not strong, and the dissolved oxygen in the pond is insufficient. Most of the harmful bacteria in the pond are anaerobic bacteria. When the dissolved oxygen in the pond is insufficient, the anaerobic bacteria will multiply in large numbers, causing the pond Substrate deterioration, vannamei physical decline, prone to disease
At the same time, under low temperature stress, the feed intake of Penaeus vannamei slows down, resulting in some feed being dissolved and wasted in the water. The enzyme activity in the Penaeus vannamei body decreases, resulting in an increase in the feed coefficient. The increasingly serious pollution leads to the frequent occurrence of diseases, which seriously plague the healthy development of the aquaculture industry, seriously restrict the low-temperature production of Penaeus vannamei, and hinder the further development of the Penaeus vannamei aquaculture industry

Abstract

The invention relates to aquaculture feed, in particular to litopenaeus vannamei compound feed special for winter shed cultivation and a preparation method of the feed. The feed comprises a protein source raw material, a fat source raw material, a sugar source raw material, an antioxidant, a phagostimulant, composite vitamin and composite mineral salt. The invention provides the litopenaeus vannamei compound feed special for winter shed cultivation and the preparation method of the feed, with the advantages of high survival rate, high growth speed, high stability in water, high ingestion speed, convenience for use and low environmental pollution, so as to solve the problems of low growth speed, serious disease, low survival rate and the like of the litopenaeus vannamei during winter shed cultivation at low temperature and promote the healthy development of the litopenaeus vannamei cultivation industry.

Description

technical field [0001] The invention relates to an aquaculture feed, in particular to a compound feed for Penaeus vannamei specially used for aquaculture in a winter shed and a preparation method thereof. Background technique [0002] Shrimp is one of the most popular seafood products. Shrimp farming has brought good economic benefits to fish farmers. Penaeus vannamei has become a conventionally farmed species due to its fast growth, short breeding cycle and high population yield. However, because Penaeus vannamei is native to the tropical regions of Central and South America, its cold resistance is low, and the lethal water temperature is only 9°C. Therefore, the cultivation of Penaeus vannamei is limited by temperature conditions. Most of the fish farmers in our country use open-air ponds to breed Penaeus vannamei, which is obviously restricted by temperature. Now, shrimp farmers in some areas of my country, such as in Zhuhai, Guangdong, Zhongshan, and Xiaoshan, Zhejiang...
