Embodiment 1

[0033] A mandarin fish feed attractant, the mandarin fish feed attractant added in every kilogram of feed is prepared from the following raw materials: pig liver 2.0g, dimethyl-beta-propionate thiotin hydrochloride 0.2g, trimethylamine oxide 1.0g, L-glycine 0.3g, inosine nucleotide 20g, betaine 1.5g, L-alpha-alanine 10g, cuttlefish offal powder (purchased from Cangzhou Haitong Biological Feed Co., Ltd.) 15g.

[0034] The preparation method of described animal liver extract is:

[0035] Take fresh pig liver, homogenize it, soak it in pure water for 10 hours at 25°C, and centrifuge to obtain feed liquid and feed residue. The feed liquid is firstly separated by a hollow fiber ultrafiltration membrane with a molecular weight cut-off of 40KDa. The primary concentrated solution is obtained, and then the primary concentrated solution is concentrated to the minimum volume with a roll-type nanofiltration membrane with a molecular weight cut-off of 250KDa to obtain a re-concentrated li...

Embodiment 2

[0039] A mandarin fish feed attractant, the mandarin fish feed attractant added in every kilogram of feed is prepared from the following raw materials: pig liver 2.0g, dimethyl-beta-propionate thiotin hydrochloride 0.3g, trimethylamine oxide 1.8g, L-glycine 0.4g, hypoxanthine nucleotide 25g, betaine 2.0g, L-alpha-alanine 12g, squid offal powder (purchased from Cangzhou Haitong Biological Feed Co., Ltd.) 12g.

[0040] The preparation method of described animal liver extract is:

[0041] Take fresh bovine liver, homogenize it, soak it in pure water at 26°C for 9 hours, and centrifuge to obtain the feed liquid and feed residue. The feed liquid is firstly separated by a hollow fiber ultrafiltration membrane with a molecular weight cut-off of 40KDa. The primary concentrated solution is obtained, and then the primary concentrated solution is concentrated to the minimum volume with a roll-type nanofiltration membrane with a molecular weight cut-off of 150KDa to obtain a re-concentra...

Embodiment 3

[0045]A mandarin fish feed attractant, the mandarin fish feed attractant added in every kilogram of feed is prepared from the following raw materials: pig liver 2.0g, dimethyl-beta-propionate thiotin hydrochloride 0.5g, trimethylamine oxide 2.0g, L-glycine 0.5g, inosine nucleotide 25g, betaine 3.0g, L-alpha-alanine 15g, cuttlefish offal powder (purchased from Cangzhou Haitong Biological Feed Co., Ltd.) 15g.

[0046] The preparation method of described animal liver extract is:

[0047] Take fresh pig liver, homogenize it, soak it in pure water for 10 hours at 28°C, and centrifuge to obtain the feed liquid and feed residue. The feed liquid is firstly separated by a hollow fiber ultrafiltration membrane with a molecular weight cut-off of 40KDa. The primary concentrated solution is obtained, and then the primary concentrated solution is concentrated to the minimum volume with a roll-type nanofiltration membrane with a molecular weight cut-off of 300KDa to obtain a re-concentrated...

Abstract

The invention discloses a siniperca chuatsi feed phagostimulant and a preparation method thereof. The siniperca chuatsi feed phagostimulant added to each kilogram of feed is prepared from the following raw materials by weight: 2.0g of animal liver extract, 0.2-0.5g of dimethyl-beta-propiothetin, 0.5-2.0g of trimetlylamine oxide, 0.2-0.5g of L-glycine, 20-25g of hypoxanthine nucleotide, 0.5-3.0g ofbetaine, 10-15g of L-alpha-alanine and 10-15g of cuttlefish viscera powder. The preparation method of the phagostimulant is as follows: taking the betaine, sequentially adding the animal liver extract, the dimethyl-beta-propiothetin, the trimetlylamine oxide, the L-glycine, the hypoxanthine nucleotide, the alanine and the cuttlefish viscera powder, conducting full uniform mixing once finishing adding one raw material, and finally conducting full uniform mixing. The phagostimulant is reasonable in formula, can improve the feeding rate, feeding-taming survival rate and weight gain rate of siniperca chuatsi, and can reduce feed coefficient. The preparation method of the phagostimulant is simple, and is convenient to operate and low in preparation cost.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a feed attractant for mandarin fish and a preparation method thereof. Background technique [0002] Siniperca, also known as mandarin fish (Siniperca chuatsi), is a rare freshwater fish belonging to the suborder Perciformes, commonly known as osmanthus fish, fat mandarin fish, and seasonal flower fish. The feeding habits of mandarin fish are very peculiar. From the time when the fry open their mouths to feed, they live on live fish and shrimp for life, and generally refuse to eat artificial compound feed. This phenomenon is very rare in freshwater fish. [0003] Due to its fast growth rate and high nutritional value, it has become more and more popular among consumers and has become the main species in China's famous and high-quality aquaculture. The demand of market consumers is in short supply, and the market price Constantly rising, reaching 70-80 yuan per kil...
