Preparation method of water-insoluble feed for fishes, shrimps and crabs

Abstract

The invention discloses a preparation method of a water-insoluble feed for fishes, shrimps and crabs, wherein the water-insoluble feed is prepared from the following feed raw materials: 10-30% of fish powder, 10-30% of shrimp powder, 10-30% of peanut powder, 10-30% of bean powder, 1-5% of milk powder, 0.1-0.5% of vanillin, and 0-0.4% of preservative. The preparation method specifically comprises: (1) preparing raw material mixing powder; (2) preparing a binder; (3) mixing the feed mixing powder and the starch binder; and (4) granulating, and drying. According to the present invention, the preparation method is suitable for the preparation by aquaculture users and fancy fish breeding enthusiasts, and is suitable for industrial large-scale production; and the storage time of the feed in the water can be freely adjusted through the binder adding amount and the stirring time, such that the water deterioration caused by the excessive bait capable of being completely taken by fishes, shrimps and crabs can be prevented.

Description

technical field [0001] The invention relates to a feed, in particular to a method for preparing a water-insoluble fish, shrimp and crab feed. Background technique [0002] The feed for feeding aquatic fish, shrimp and crab is divided into two categories: natural live bait feed and artificial feed. The former are mainly larvae of some aquatic insects, fleas and so on. The latter is mainly a granular feed suitable for various growth periods of aquatic organisms prepared from various feed materials through modern granulation processes. The difficulty in making artificial feed is that it is easy to disintegrate and dissolve in water. If the amount of feeding is too much at one time, it will quickly cause a large number of bacteria in the breeding pond, and the water quality will deteriorate extremely, resulting in a large number of deaths of fish, shrimp and crabs. Contents of the invention [0003] The purpose of this invention is to provide a kind of water-insoluble fish, ...
