Additive premix for high-salinity cultured pennaus vannamei feed

Abstract

The invention discloses an additive premix for a high-salinity cultured pennaus vannamei feed. The premix comprises composite vitamins and composite trace elements, wherein the composite vitamins and the composite trace elements are mixed in a ratio of 1: (2-4) to prepare the premix, and 20 to 30kg of the premix is added in every ton of the pennaus vannamei feed. The additive premix of the high-salinity cultured pennaus vannamei feed is stable in raw material source, high in nutrition value, capable of meeting the needs of high-salinity cultured pennaus vannamei on vitamins and trace elements, is safe, efficient and free of toxic and side effects if used for a long time; the vitamins and the trace elements in the premix for the pennaus vannamei feed are prepared separately, and therefore the relative stability of physicochemical properties among the various nutrients is ensured and a high biological value is achieved; the additive premix for the high-salinity cultured pennaus vannamei feed is capable of remarkably enhancing the immune function and the anti-stress ability of pennaus vannamei in a high-salinity culture environment, and the cultured pennaus vannamei grows fast, is high in feed conversion rate, is full of vitality, has a bright body colour, and is high in survival rate.

Description

technical field [0001] The invention relates to a shrimp feed additive premix, in particular to a high salinity cultured Penaeus vannamei feed additive premix. Background technique [0002] Vannamei prawns ( Litopenaeus vannamei ), commonly known as Penaeus vannamei, is a hygrosaline crustacean native to the Americas. This species has quickly become an upstart in the world's aquaculture industry due to its large aquaculture output, high meat yield, ease of intensive farming, and delicious meat quality. The output has been ranked first in the world's shrimp production for nearly ten years. The cultivation area and production of Penaeus vannamei in my country have also expanded rapidly in the past decade. The aquaculture area in China has reached several hundred thousand mu, and the aquaculture output has reached more than 1 million tons. It is the largest country in the world of shrimp farming and export. In view of its hygrosaline biological habit, the cultivation of Penae...

Problems solved by technology

Although there are many studies and reports on the nutrition and feed additive premix of Penaeus vannamei, most of these reports are concentrated in low-salinity aquaculture environment (salinity 0.5‰-5‰) and medium-low salinity aquaculture environment (salt 5‰-20‰), while there are few research reports and data in high salinity breeding environment (salinity 20‰-35‰)

Under high-salinity aquaculture environment, the stress effect caused by changes in the salinity and mineral element content of the aquaculture water will lead to changes in the physiological activity, immune function and nutritional requirements of Penaeus vannamei. Seriously affect its survival rate, aquaculture output and muscle quality, and then affect the output and product quality of the high-salinity cultured Penaeus vannamei aquaculture industry, thereby affecting the sustainable development of my country's prawn aquaculture industry and the improvement of people's living standards
