Problems solved by technology

[0003] The purpose of the present invention is to make up for the fact that the existing seawater cultured prawn feed cannot meet the changes in the physiological functions and nutritional requirements of Penaeus vannamei cultured in low-salinity waters, resulting in low aquaculture output, poor aquaculture quality, and ecological imbalance in aquaculture waters. Insufficiency of existence, providing a low-salinity cultured Penaeus vannamei environment-friendly compound feed

Embodiment Construction

[0020] Weigh 35kg of red fish meal, 11kg of soybean meal, 7kg of peanut bran, 3kg of meat and bone meal, 6kg of shrimp bran, 6.7kg of cotton meal, 5kg of squid offal powder, 23kg of high-gluten flour, 1.5kg of soybean lecithin, 0.4kg of choline chloride, Vitamin C-phosphate 0.1kg, calcium dihydrogen phosphate 0.8kg, compound multidimensional 0.2kg and compound mineral salt 0.3kg, crush these raw materials through an 80-mesh sieve, add 1kg of sea fish oil, then mix well, and then pass through the conventional prawn feed The production line is granulated to obtain the environment-friendly compound feed for cultured Penaeus vannamei with low salinity. The compound multidimensional and compound mineral salts used in this compound feed are disclosed substances (see Cheng et al., "Aquaculture" Aquaculture (2006) sponsored by the Netherlands, 251: 472-483; Cheng et al., "Aquaculture Nutrition" sponsored by Norway "Aquaculture Nutrition (2005), 11:385-393).

Abstract

The present invention relates to an environment-protecting type mixed feed for making low-salinity culture of Fanna prawn. The raw material composition of said feed includes (by wt%) 20-40% of red-fish powder, 10-20% of soybean dregs, 7-16% of peanut shell meal, 3-8% of bone powder, 5-10% of shrimp bran, 4-10% of cotton seed cake, 4-10% of cuttle-fish guts powder, 18-25% of glutenous flour, 1.0-2.0% of soybean lecithin, 1.0-2.0% of sea-fish oil, 0.2-0.5% of choline chloride, 0.05-0.1% of vitamin C-organic phosphate, 0.5-1.0% of calcium dihydrogen phosphate, 0.2-0.5% of compound polyvitamin and 0.3-1.5% of compound mineral salt. Said feed is high in conversion rate, 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 an environment-friendly compound feed for breeding Penaeus vannamei with low salinity. 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 Pen...
