Example Embodiment

[0051] Example 1 Preparation of low-fluorine Antarctic krill powder

[0052] 1. Preparation of modified bagasse powder:

[0053] (1) The bagasse is dried or sun-dried, then crushed and sieved to obtain bagasse powder;

[0054] (2) After immersing the bagasse powder in 25% sodium hydroxide solution for 6.5 hours, washing and filtering;

[0055] (3) Soak again in 1.7g / L potassium permanganate solution, react at 60℃ for 2h;

[0056] (4) Wash, filter, and dry the product treated in (3) to obtain modified bagasse powder.

[0057] 2. Preparation of low-fluorine Antarctic krill powder:

[0058] (1) Antarctic krill is hydrolyzed, screened, and cleaned, kept in 80°C water for 10 minutes, then immersed in distilled water with pH 4.8, 100W ultrasonic treatment for 4 hours for pre-defluorination, and distilled water is changed every 1 hour during the treatment;

[0059] (2) Use modified bagasse powder for defluorination treatment: add modified bagasse powder into distilled water at a ratio of 20g / L, a...

[0063] Example 2 Optimization of preparation process of low-fluorine Antarctic krill powder

[0064] 1. The effect of modified bagasse powder on the fluoride content of Antarctic krill powder

[0065] (1) The influence of the concentration of sodium hydroxide solution on the fluorine content in krill meal

[0066] According to the method for preparing modified bagasse powder in Example 1, a series of modified bagasse powders were prepared with the concentration of sodium hydroxide solution as a single variable. Then, a series of Antarctic krill powder was obtained according to the method for preparing Antarctic krill powder in Example 1. The fluorine content in Antarctic krill meal was determined, and the shrimp meal yield was calculated.

[0067] The results are shown in Table 1. When the concentration of the sodium hydroxide solution is 25-35%, the fluorine content of Antarctic krill powder is lower.

[0068] Table 1 The influence of sodium hydroxide solution concentration on the fl...

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...
