Production method for floating fish feed

Abstract

The invention discloses a production method for floating fish feed. The production method comprises the following production steps: firstly, adopting the following raw materials in percentage by weight: 10 percent of corn, 20 percent of cornstalk, 10 percent of soybean powder, 10 percent of wheat bran, 10 percent of fishbone dust, 30 percent of cassava meal and 10 percent of lard oil; secondly, pulverizing the corn into particles with the diameters of 1-2mm; thirdly, crushing the cornstalk into crushed particles with the diameters of below 1mm; fourthly, uniformly mixing the crushed corn particles, the crushed cornstalk particles, the soybean powder, the wheat bran and the fishbone dust to form mixed feed; fifthly, mixing the cassava meal and the lard oil, heating the mixture and 3 times of water and stirring to obtain cooked thin paste liquid; sixthly, uniformly stirring the cooked thin paste liquid and the mixed feed to obtain wet mixed feed; eighthly, drying the wet mixed feed to obtain the floating fish feed.

Description

technical field [0001] The invention relates to a method for making feed for floating water fish, which belongs to the technical field of breeding. Background technique [0002] In our country, fish farming is an important part of aquaculture. Fish culture can be divided into pond culture and pen culture. The density and quantity of pond culture are limited by water quality, and the water needs to be changed frequently. Pen aquaculture is to use a net to circle a certain volume of water in rivers and lakes for aquaculture. The water quality of pen aquaculture is better. However, due to the fluidity of water, it is difficult to raise fish in pen aquaculture, and the running water is easy to wash away the feed. Or sink into the lower net circle and cause waste. Therefore, the quality of fish feed should be large and buoyant. The general raw materials for making fish feed are made by pressing a fluffy plant object with starch or soybean powder, so that the feed can have grea...

Problems solved by technology

But because Peng Song shape plant is generally the stem of some plants, as stalk, timber, forage etc., the granule after these materials pulverizes is difficult to be bonded with starch or bean flour, is bonded in workshop with pressure exactly, but Once put into the water, it is quickly dissolved and dispersed by the water before the fish can swallow it, causing a lot of waste
