Plectropomus leopardus adult feed and preparation method thereof

Abstract

The invention discloses a plectropomus leopardus adult feed. The fish feed is prepared from the following components in parts by weight of 500-520 parts of super red fish meal, 140-160 parts of shrimppowder, 30-70 parts of starch, 90-96 parts of common flour, 20-40 parts of corn protein powder, 80-100 parts of fish oil and 74-80 parts of nutrients. The prepared materials are mixed with a double-shaft paddle high-efficiency mixer, the mixed materials are smashed, the crushed materials are pelletized through a bulking machine, then the product is taken out from a pelleter and then is sent intoa circulating box dryer for drying, the dried product is sent into a rolling shaft type countercurrent cooler for cooling, and next, the cooled product is quantitatively packaged and sewn and packagedand labeled automatically. By adoption of the technical scheme, the effect of increasing the red color of the fish body can be promoted, the red increasing speed is high, the feeding is strong, the growth speed is high, and the fish body digestion and absorption are strong.

Description

technical field [0001] The invention relates to a method for preparing a fish feed product, in particular to a method for preparing a fish feed for Dongxing spot, belonging to the field of aquatic feed processing. Background technique [0002] Eastern star spot, a kind of fish of the genus Gillidae, has a bright color and is very suitable for keeping in a mixed tank of ferocious fish. The eastern star spot is a very ferocious predator and will swallow any fish it can swallow. Will eat ornamental shrimp and other crustaceans. Unlike cannonball fish, eastern starfish will swallow their prey whole instead of biting, and will not harass fish they cannot swallow. They can be mixed with other species of eastern starfish, but will Fighting with other East Star Spots, the food includes all kinds of sea fish, squid, shellfish and shrimp. It needs to provide some live food frequently, and enough nutrition will maintain its color. [0003] For example, the patent document with the app...

AI Technical Summary

Problems solved by technology

[0003] For example, the patent document with the application number CN201610938463.1 discloses the extruded and sinking compound feed for adult fish of the eastern star group. The feed provided in this patent cannot exist in water for a long time, and the adult fish feed in water is dissolved in a short time Faster speed leads to faster loss of nutrients in the adult fish feed, and the fish cannot eat in time, so the growth of the fish is slower

[0004] Most of the existing feeds are buoyant feeds and semi-sinking feeds, but the eastern starfish tends to eat food suspended in the water body, and generally does not eat sinking feeds

[0005] The current semi-sinkable feed has poor water resistance and is suspended in water for a short time, resulting in the loss of nutrients in the feed and affecting the absorption of fish

[0006] In the prior art, the addition of hormones to adult fish feed is serious, resulting in low quality fish meat, and cannot make the fish body reddened.
