Problems solved by technology

[0005] The compound feed for juvenile turbot of the present invention has the following characteristics: 1. It can meet all the nutritional needs of juvenile turbot (2-10cm) under artificial breeding conditions; 2. The feed has good palatability, high feed conversion rate, 3. The feed has good stability in water; 4. Juvenile turbot grows fast and has a high survival rate; 5. The raw materials used in the compound feed are easy to obtain and low in cost; the production process is simple, thus effectively It solves the feed problem of artificial breeding of turbot and is beneficial to environmental protection

Embodiment Construction

[0006] Weigh 32kg of white fish meal, 18kg of Peruvian red fish meal, 6.5kg of spirulina powder, 5kg of soybean protein concentrate, 8kg of squid meal, 3kg of beer yeast, 22kg of high-gluten flour, 1kg of soybean lecithin, 0.5kg of cholesterol, 2.5kg of sea fish oil, chlorine Choline 0.3kg, sea fish liver tonic 0.2kg, compound multidimensional 0.4kg, compound mineral salt 0.6kg. These raw materials, except sea fish oil and cholesterol, are pre-crushed and passed through a 120-mesh sieve, and then all raw materials are mixed evenly by a twin-shaft paddle mixer; Size adjustment feed particle size), dehydration, cooling, namely made the turbot juvenile compound feed. Complex multidimensional and complex mineral salts for use in the present invention are known (see Schuhmacher et al., Aquaculture (1997), 151:15-28).

[0007] From April 20th to May 20th, 2004, in Laizhou, Rongcheng, Shandong and other places, the juvenile turbot was cultured for 30 days with the feed of the presen...

Abstract

A composite feed for the young turbot is prepared from 14 raw materials including anabarilius powder, spirulina powder, concentrated soybean protein, squid powder, beer yeast, soybean lecithin, etc. Its advantages are rich nutrients, high conversion rate, high growth speed, and less pollution to water.

Description

technical field [0001] The invention relates to a feed, in particular to a compound feed for juvenile turbot. Background technique [0002] Turbot is a rare and valuable marine economic fish. In recent years, large-scale artificial breeding has begun in northern my country. The fish grows fast, has good meat quality and high nutritional value. It is very popular among consumers and has a good market prospect. At present, my country has successfully mastered the technology of fully artificial seedling breeding and full-cycle breeding of turbot, but due to the imperfect nutritional demand parameters, high-quality full-price compound feed has not been developed, especially the formula for juvenile turbot. The quality of the feed is even lower, seriously affecting the supply of large-scale fish species, thereby limiting the scale of turbot farming to a large extent. Contents of the invention [0003] The purpose of the present invention is to provide a kind of turbot juvenile...
