Juvenile gobiocypris rarus feed and preparation method thereof

Abstract

The invention discloses a juvenile gobiocypris rarus feed and a preparation method thereof. The juvenile gobiocypris rarus feed is prepared from fish meal, dextrin, a mineral substance mixture, soybean oil, a vitamin mixture, cellulose, spiral seaweed powder and a binding agent in a certain proportion. The preparation method comprises the following steps: 1, crushing raw materials; 2, respectively weighing the fish meal, the dextrin, the mineral substance mixture, the soybean oil, the vitamin mixture, the cellulose, the spiral seaweed powder and the binding agent; 3, uniformly the weighed fish meal, the dextrin and the cellulose; 4, mixing the mineral substance mixture, the vitamin mixture and the spiral seaweed powder, and continuously mixing; 5, adding the soybean oil for mixing; 6, adding the binding agent in water, mixing to prepare an emulsion, adding a mixture, and mixing; and 7, preparing the mixture into granules by using a granulating machine to obtain a granular feed. The juvenile gobiocypris rarus feed is reasonable in formula, and convenient to use; the survival rate of the juvenile gobiocypris rarus feed can reach above 98 percent, the requirement of daily growth of the juvenile gobiocypris rarus is met, the quantity of pathogenic microorganisms carried by live baits is reduced, and the quality uniformity of the juvenile gobiocypris rarus as an experimental animal is improved.

Description

technical field [0001] The invention relates to a fish feed, more specifically to a feed for young gobiocypris rarus, a small carp fish, and a preparation method for the feed for the rare gobiocypris rarus. Background technique [0002] Rare gobi ( Gobiocypris rarus Ye et Fu) belongs to the family Cyprinidae, the subfamily of cyprinidae, the genus of genus cyprinus, the common name is Jinbai Niang, and the English name is Rare Minnow. It is a small carnivorous fish unique to my country. "Cao Wenxuan, Wang Jianwei, 2003. Rare gobi—a new fish experimental animal. Experimental animal science and management, S1:96-99" comprehensively described the research on A large number of studies have been carried out on the rare gobi carp, including distribution area, living habits, morphological characteristics, karyotype, isozyme, growth, development and reproduction, etc. Rare gobi crucian carp is small in size (adult fish 3-8cm), short maturation period (4 months old can reach sexua...

AI Technical Summary

Problems solved by technology

[0004] There are few studies on the bait of rare gobi crucian carp, "Study on the food intake of rare gobi crucian carp to Culex larvae", "Journal of Hydrobiology", Wang Jianwei, 1993 , 17: 290-292 proposed the active feeding of rare gobi crucian carp on Culex larvae, and the food intake is relatively large; "Study on the biochemical composition of rare gobi carp and its feed", "Journal of Hydrobiology", Wu Zhiqiang et al., 1999, In 23:697-699, the biochemical composition of rare goblin carp live bait water earthworms and some artificial feeds was determined, and the biochemical composition of muscle and gonads of rare goblin carp under different bait conditions were studied, including water, protein, fat, ash, The results show that water earthworms can guarantee the normal growth and reproduction needs of the rare goby carp, but the artificial feed used here is a commercial feed for juvenile soft-shelled turtles, and its nutritional composition needs to be adjusted for the rare goblin carp. Perfect; "Research on the Effects of Artificial Feeds on the Reproduction of Rare Scorpio", "Sichuan Animals", Wu Zhiqiang et al., 2001, 20:174-176, used water earthworms and 4 kinds of artificial compound feeds with high protein levels to improve the reproductive nutrition of rare Scorpio. Research is needed. Although the rare gobi can carry out reproductive activities when fed with artificial compound feed, it is difficult to achieve the effect of feeding with water worms, and the spawning interval is longer or the number of eggs is lower.

In summary, so far, no studies have been conducted on the formulation of a complete artificial diet for the growth of rare gobi juveniles
