Embodiment Construction

[0006] Weigh 22kg of α-starch; 35kg of Peruvian red fish meal; 14kg of soybean meal; 10kg of second meal; 5kg of squid viscera powder; Sea fish liver strengthening agent 0.5kg; β-glucan 0.3kg; compound multidimensional 0.5kg; compound mineral salt 0.7kg. All the above-mentioned raw materials except seawater fish oil are crushed through a 80-mesh sieve, and then all the raw materials are mixed uniformly, which is the concentrated feed for adult turbot of the present invention. The concentrated feed is mixed with fresh miscellaneous fish in a weight ratio of 1:2, beaten by a machine to make wet pellet feed (the particle size of the feed is determined according to the size of the fish body), and stored in a freezer at -20°C. 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 to November in 2004, adult turbot fish were cultured with the feed of the present inven...

Abstract

The concentrated feed for adult turbot consists of: alpha-starch 20-25 wt%, Peru red fish meal 30-40 wt%, soybean dregs 10-20 wt%, wheat flour 5-12 wt%, squid bowel powder 5-10 wt%, animal bone meal 5-10 wt%, beer yeast 3-7 wt%, and other seven kinds of material. The feed of the present invention has the features of: capacity of providing adult turbot under artificially raising with all the nutrients, good taste, high feed conversion rate, high stability in water, functions of promoting the growth of adult turbot and raising it disease resistance and survival rate, low cost, etc.

Description

technical field [0001] The invention relates to a feed, in particular to a concentrated feed for turbot adult fish. 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. Now my country has successfully mastered the fully artificial nursery technology and full-cycle breeding technology of turbot. During the growth period of turbot, wet pellet feed (concentrated feed plus fresh miscellaneous fish beating and pelleting) is a commonly used bait, but the formula of concentrated feed used in making wet pellet feed is unscientific, resulting in The nutrition is not comprehensive, the stability of the feed in water is poor, the feed efficiency is low, the breeding cost is high, and it is easy to pollute the water quality, which is not c...
