Mantis shrimp mixed feed and preparation method thereof

Abstract

The invention discloses a mantis shrimp mixed feed which is prepared from the following raw materials in parts by weight: 25-30 parts of fish meal, 10-15 parts of bean pulp, 9-11 parts of peanut meal, 5-7 parts of beer yeast, 10-15 parts of maize puffing powder, 7-10 parts of shrimp shell powder, 0.1-0.3 part of choline chloride, 0.1-0.2 part of unshelling element, 1-2 parts of monocalcium phosphate, 0.3-0.5 part of licorice powder, 0.5-1 part of chitosan, 1-1.5 parts of fish oil, 0.1-0.3 part of dehydrogenation sodium acetate, 0.2-0.4 part of sodium humate, 0.3-0.5 part of complex enzyme, 0.2-0.3 part of complex vitamin, 2.2-2.5 parts of complex mineral salt, 0.2-0.4 part of a complex binder and 1-3 part of a complex phagostimulant. The mantis shrimp mixed feed is designed aiming at biochemical structures and nutritional requirements of mantis shrimps, and is reasonable in formula, easy to digest and absorb, high in utilization and beneficial to the survival and the growth of the mantis shrimps. The invention also discloses a preparation method of the mantis shrimp mixed feed. The preparation method comprises the following steps: (1) weighing materials; (2) premixing; (3) stirring the materials; (4) tempering and palletizing; and (5) drying and packaging. The preparation method is simple in process steps, low in cost, low in feed nutrient loss and suitable for being used in industrialized mass production.

Description

technical field [0001] The invention relates to a compound feed, in particular to a mantis shrimp compound feed and a preparation method thereof. [0002] Background technique [0003] Mantis shrimp, commonly known as shrimp crawler, mantis shrimp, shrimp spring and so on. Belonging to the phylum Arthropoda, Crustacea, Stomatopoda, and Mantisidae. Mantis shrimps are widely distributed, delicious and nutritious, and are favored by consumers. With the improvement of people's living standards, consumers' demand for living mantis shrimps is increasing day by day, and fishing mantis shrimps from the sea is far from meeting the market demand. Therefore, artificial breeding of mantis shrimps has broad development prospects. With the in-depth study of mantis shrimp artificial breeding technology and the development of breeding technology, the mantis shrimp farming industry has developed rapidly, the scale of breeding has been continuously expanded, and the output has been continu...

Problems solved by technology

Up to now, the feed used in mantis shrimp farming is mainly natural small fish, shrimp and shellfish, etc., while natural biological bait not only destroys marine fishery resources, but also has limited resources, cannot guarantee timely and sufficient supply, is inconvenient to use (needs to be frozen), and is nutritious. The structure is single, and it is easy to rot and decompose after feeding, which will spoil the water quality and cause the disease to spread. It is difficult to adapt to the growing demand for bait for mantis shrimp farming.

Although a small number of farmers have tried to make their own compound feeds for mantis shrimps, the results are not satisfactory. The main reason is that they have not designed and screened a reasonable feed formula according to the nutritional needs of mantis shrimps, resulting in slow growth of mantis shrimps. Severe cases can even cause death without moulting
