Problems solved by technology

The feed utilization rate is low and the feed coefficient is large, which will lead to more residual bait deposition, resulting in eutrophication of aquaculture water, high nitrogen and phosphorus discharge, heavy pollution of cage waters, frequent fish diseases, and decreased survival rate. The production is reduced, and the cost of farming per unit of fi

Abstract

The invention discloses floating full-ripened pellet feed for marine fishes, and a preparation method thereof. The floating all-ripened pellet feed has the density of not greater than 1 and the ripened degree of 100 percent. The preparation method comprises: taking brown fishmeal, blood globulin powder, cottonseed kernel protein powder, flour, wheat, non-transgenic soybean meal, rapeseed meal, cassava pieces, mineral premix, vitamin premix, monocalcium phosphate, fish oil, calcium propionate, oligosaccharide as raw materials; proportioning the raw materials according to part by weight to form feed base material; using double-shaft extrusion full-ripening expansion machine to adjust quality under the steam pressure between 0.4 and 0.5 MPa, at the humidity between 19 and 23 percent and at the temperature between 85 and 90 DEG C; and ripening the obtained product for 90 to 120 seconds, wherein the expansion parameters of an extruder are as follows: a ripening temperature of 180 DEG C, the chamber pressure between 22 and 28 atm and a screw speed of 450 to 550 r/min. The feed has the advantages of low density, full-ripened property, all destroyed anti-nutritional factors, high stability in water and small feed coefficient.

Description

technical field [0001] The invention relates to a feed for seawater fish, in particular to a buoyant fully matured granular feed for seawater fish and a preparation method thereof. Background technique [0002] With the application of marine cage culture and supporting technologies, the marine fish farming industry has developed rapidly, such as large yellow croaker, American red croaker, black catfish, perch and white fish, etc., and the number of seawater cages in the country has reached nearly one million boxes. At present, seawater fish farming is generally fed with chilled miscellaneous fish, and hard pellet feed is also used. Feeding chilled miscellaneous fish has a higher unit fish breeding cost, low utilization rate, more residual bait, and a feed coefficient greater than 7. . Hard pellet feed is generally produced by ring die pressing pellets under the condition that the curing temperature is not higher than 135°C and the cavity pressure is 3.8-4.2 atm. Hard pellet...
