Fish culturing feed additive with cuttlefish internal as main material

Abstract

The present invention provides one kind of fish feed additive and its production process. The fish feed additive has ink fish organ as main material and is suitable for raising sea water fishes, especially prawn. It can balance nutrients, provide prawn with feasible energy and amino acids, and provide proper amount of chlesterol to promote growth of prawn during desquamation. During the production, fresh ink fish organ as main material is fermented naturally or enzyme fermented via adding composite lactic acid bacteria, which is obtained through culture and propagation in composite fruit juice or molasses, as fermentation promoter. Higher protein contained in ink fish organ is decomposed, so as to produce fish feed additive containing rich amino acids and unsaturated fatty acid.

Description

technical field [0001] The invention relates to a feed additive for fish farming and a manufacturing method thereof. The feed additive for fish farming uses cuttlefish viscera as the main raw material and is applied to fish culture on the surface of sea water, especially when added to shrimp feed, not only can the nutrients be balanced , can also supply the high energy and amino acid needed for the growth of shrimp, and supply the right amount of cholesterol in the process of peeling the shrimp to promote the growth of the shrimp. Background technique [0002] In the past, squid viscera were mainly used as feed additives for shrimp and fish through the following processing techniques. [0003] That is, put the collected squid viscera in an iron kettle, heat it with steam to above 120°C, boil it for about 3 hours or more to evaporate the water, separate the fat part by concentrating and heating, extract it as squid liver oil, and the remaining paste The product is called squ...

AI Technical Summary

Problems solved by technology

[0010] (e) The production process is very complicated and requires high investment in facility fees, which consumes a lot of time and costs and increases production costs

[0011] As mentioned above, the previous feed additives made mainly of cuttlefish viscera were not suitable for fish farming, especially for the rapid growth of shrimp, due to a large number of problems in the heating and concentration process.
