Problems solved by technology

Although much research has been done on Penaeus vannamei in mariculture, however, farming research in freshwater conditions is relatively new and uncharted territory
The low-salinity aquaculture environment is due to the stress effect caused by changes in the salinity and mineral element content of the aquaculture water, resulting in changes in the physiological activity, immune function, and nutritional requirements of Penaeus vannamei. At the same time, it is more sensitive to the toxic effects of physical and chemical water quality. If things go on like this, it will inevitably lead to serious consequences such as low aquaculture output, poor aquaculture quality and ecological imbalance in aquaculture waters, which will most affect the market competitiveness and sustainable development of freshwater aquaculture Penaeus vannamei

Embodiment Construction

[0037] This additive premix needs to prepare compound vitamins and compound minerals separately. The compound vitamins are formulated as follows (based on the amount added per ton of feed). Accurately calculate the active ingredient content of each raw material and accurately weigh vitamin A 40g, vitamin D 25g, vitamin E 150g, vitamin K3 40g, vitamin B1 40g, vitamin B2 40g, vitamin B6 50g, vitamin B12 6g, niacin 70g, calcium pantothenate 50g, folic acid 8g, biotin 30g, inositol 200g, vitamin C ester 800g, carnitine 100g, antioxidant 150g, antifungal agent 400g, Bacillus subtilis 1200g, immune polysaccharide 1000g, dehullin 300g, bran 301g, the order of feeding is to put the bran first, then add the other raw materials mentioned above, mix well Rear packaging label.

[0038] The compound minerals are prepared as follows (based on the amount added per ton of feed): According to the accurate calculation of the active ingredient content of each raw material, accurately weigh 8500g...

Abstract

The present invention belongs to the field of aquaculture feed technology, in particular, it relates to an additive premixed material for low-salinity culture of Fanna prawn. Said additive premixed material is composed of vitamin complex and compound mineral matter. Said additive premixed material can be added into prawn feed, and said feed can raise immunity of prawn, and can promote quick growth of prawn, its conversion rate is high and its feed coefficient is 0.9-1.3.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a low-salinity cultured Penaeus vannamei additive premix. Background technique [0002] Vannamei shrimp (Litopenaeus vannamei), commonly known as Penaeus vannamei, is a euryhaline crustacean native to the Americas. This species has quickly become a popular aquaculture industry due to its large output, high meat yield, easy intensive farming, and delicious meat. Its output has been ranking first in the world's shrimp output for nearly ten years. In view of its eurosalinity (0.5--4.0), Penaeus vannamei not only spreads all over the seawater areas of coastal provinces, but even has a certain freshwater aquaculture market in the interior. Statistics in 2003 showed that the output of Penaeus vannamei in low-salinity (0--5) culture (that is, freshwater culture) in my country accounted for about 50% of the total. Although much has been done on Penaeus vannamei in mariculture ...
