Application of euphausia superba powder in preparing color-enhancing feed for gold arowana

Abstract

The invention discloses an application of euphausia superba powder in preparing color-enhancing feed for gold arowana and the color-enhancing feed for the gold arowana. The color-enhancing feed is prepared from the following components in mass percentage: the euphausia superba powder 5%-70%, soy protein concentrate 1%-20%, cicada pupa powder 1%-7%, barley pest powder 1%-10%, cake flour 5%-24%, beer yeast powder 2%-10%, starch 1%-10%, brine shrimp 4%-20%, spirulina 2%-4%, soybean phospholipid 2%-4%, betaine 2%-4%, soybean oil 1%-3%, a vitamin compound 1%-2.5%, a mineral element compound 2%-5%, an immunoenhancer 1%-5%, bifidobacteria 0.5%-5%, plum flowers 0.5%-2%, rhodotorula glutinis 0.1%-1% and persimmon red pigment 0.1%-1%. The color-enhancing feed has good color-developing and color-enhancing effects on the gold arowana and fish bodies appear a bright color after 7-day eating and the color does not fade. The feed has good intake stimulating performance and can enhance immunity, stress resistance and survival rates.

Description

technical field [0001] The invention belongs to the technical field of aquaculture. More specifically, it relates to the application of Antarctic krill powder in the preparation of color-enhancing feed for Arowana. Background technique [0002] Scleropages formosus (scientific name: Scleropages formosus): also known as Arowana and Asian Arowana, is an ancient primitive freshwater fish native to rivers and lakes in Malaysia, Indonesia, Sumatra and other places. Adult fish are 40-50 cm long and can live for decades. The parent fish lays the eggs in the mouth until the young fish hatch, so it has the common name of "dragon spitting beads". It has been developed as an ornamental fish since the middle of the 20th century. It has attracted much attention because of its armor-like scales with shiny metallic luster, bright light color and majestic demeanor. One of the most valuable ornamental fish, there are such species as Golden Dragon, Red Dragon, and Green Dragon. Endangered...

Problems solved by technology

[0005] The technical problem to be solved in the present invention is to overcome the deficiencies of the existing color development and color enhancement technology in the arowana breeding process and the problem of high fluorine content in Antarctic krill powder, and prepare Antarctic krill powder with a fluorine content lower than 1mg / kg, and then optimize A special color-enhancing feed for Arowana has been produced, which has a good color-enhancing effect on Arowana. The fish body can take on a brilliant color without fading after eating for about 7 days. It has a beautiful body line and bright color, and has excellent effect on Arowana Food-attracting performance, easy to digest, no pollution to water quality, can significantly improve the immunity and anti-stress ability of Arowana, improve the survival rate, significantly improve the economic benefits of Arowana farming, and have a good application prospect
