Fish feed using euphausia superba as the main raw material and a preparation method thereof

Abstract

The present invention relates to fish feed using euphausia superba as the main raw material and a preparation method thereof. The feed consists of the following raw materials in parts by weight: 30-40 parts of euphausia superba head powder with a fluorine content less than 80 mu / g, 10-15 parts of soy protein concentrate powder, 8-15 parts of corn protein powder, 1-3 parts of squid paste, 0.5-1 part of kelp powder, 0.1-0.3 part of dried eucommia folium powder and 0.1-0.3 part of L-Ascorbate-2-Monophosphate. The fish feed uses combined characteristics of euphausia superba head powder chemical compositions and fish growth to design other raw materials so that the fish feed is reasonable and safe in formulation structure, can meet comprehensive demands of fish for nutrient substances, significantly improve the fish survival rate and growth rate, and reduce the feed coefficient.

Description

technical field

[0001] The invention relates to a feed for fish, in particular to a feed for fish with Antarctic krill as the main raw material and a preparation method thereof. Background technique

[0002] Antarctic krill (Euphausia superba), also known as giant krill or Antarctic krill, is a krill that lives in the waters of Antarctica in the Southern Ocean. Antarctic krill is a shrimp-like invertebrate that lives in groups, sometimes with a density of 10,000-30,000 individuals / m 3 . They feed on tiny phytoplankton, from which they convert the energy from primary production to maintain their life cycle in the pelagic zone. They are key species in the Antarctic ecosystem. In terms of biomass, they may be the most abundant on Earth. successful animal species.

[0003] Antarctic krill is a natural feed for many fish. According to the determination of biologists, Antarctic krill meat contains 17.56% protein, 2.11% fat, and all the amino acids necessary for the human body, ...

Examples

Embodiment 1

[0022] Put fresh Antarctic krill shrimp heads into a container, add 2% of the total mass of Antarctic krill shrimp heads of edible salt and 0.5% of sour agent, then seal the container, and ferment naturally at 25°C for 3 months. The fermented Antarctic krill shrimp head is fished out, drained, dried and crushed to obtain the Antarctic krill shrimp head powder.

[0023] Get 30 parts of prepared Antarctic krill shrimp head powder and 10 parts of soybean concentrated protein powder (purchased in Zhengzhou Tongchuang Yisheng Food Co., Ltd., the same below), 8 parts of corn gluten powder (purchased in Shandong Binzhou Xinghuo Biotechnology Co., Ltd., The same below), 0.5 part of kelp powder (purchased from Shandong Weihai Seaweed Powder Processing Factory, the same below) and 0.1 part of Eucommia leaf dry powder are mixed, crushed and passed through an 80-mesh sieve to obtain powdery raw materials, and then 0.1 part of vitamin C phosphate (purchased from Jingjiang Hengtong Biologic...

Embodiment 2

[0025] Put fresh Antarctic krill shrimp heads into a container, add 3% of the total mass of Antarctic krill shrimp heads of edible salt and 0.7% of sour agent, then seal the container, and ferment naturally at 30°C for 2 months. The fermented Antarctic krill shrimp head is fished out, drained, dried and crushed to obtain the Antarctic krill shrimp head powder.

[0026] Get 35 parts of prepared Antarctic krill shrimp head powder and mix with 12 parts of soybean protein concentrate powder, 11 parts of corn gluten powder, 0.7 part of kelp powder and 0.2 part of eucommia leaf dry powder, pulverize and pass through an 80-mesh sieve to obtain powdery raw materials. Then, 0.2 parts of vitamin C phosphate and 2 parts of squid paste were mixed and added to the powdered raw material. Finally, after processing and granulating, fish feed with Antarctic krill as the main raw material was prepared. The chemical composition of the fish feed prepared in this embodiment is shown in Table 1.

Embodiment 3

[0028] Put fresh Antarctic krill shrimp heads into a container, add 4% of the total mass of Antarctic krill shrimp heads with edible salt and 1% sour agent respectively, then seal the container, and ferment naturally at 35° C. for 1 month. The fermented Antarctic krill shrimp head is fished out, drained, dried and crushed to obtain the Antarctic krill shrimp head powder.

[0029] Take 40% of the prepared Antarctic krill shrimp head powder, mix with 15% of concentrated soybean protein powder, 15% of corn gluten powder, 1% of kelp powder and 0.3% of Eucommia leaf dry powder, grind and pass through an 80-mesh sieve to obtain powdery raw materials, and then mix 0.3% of vitamin C Phosphate is mixed with 3 squid paste and added to the powdered raw material. Finally, after processing and granulating, fish feed with Antarctic krill as the main raw material was prepared. The chemical composition of the fish feed prepared in this embodiment is shown in Table 1.
