A method for culturing crisped grass carp is characterized in that crisped grass carp is fed after broad beans are soaked in clean water containing immunostimulant for 10-25 hours; feeding times are as follows: 20-60 times; the use concentration is as follows: calculated by the total weight of crisped grass carp 50-120 mml/kg.

2. The crisped grass carp culture method according to claim 1, wherein crisped grass carp is fed after broad bean is soaked in clean water containing immunostimulant for 20 hours; feeding times are as follows: 20-50 times; the use concentration is as follows: calculated by the total weight of crisped grass carp, is 100 mml/kg.

3. The method for culturing crisped grass carp as claimed in claim 1 or 2, wherein said immunostimulant is selected from the group consisting of sodium polyamino acid and chitosan.

4. The crisped grass carp culture method according to claim 2, wherein crisped grass carp is fed after broad bean is soaked in clean water containing immunostimulant for 20 hours; feeding times are as follows: 24 times; the use concentration is as follows: feeding crisped grass carp for 30-50 times when water temperature is lower than 25 deg.C and total weight of crisped grass carp is 100 mml/kg.

Technical Field

The invention relates to the technical field of aquaculture, in particular to a crisped grass carp culture method.

Background

Crisped grass carp (hu-a n) is a famous and special aquatic product which is originally cultivated in Yangtze reservoir of Zhongshan city, Guangdong province by using mineral water and concentrated feed of the reservoir and using a running water intensive cultivation method. The fish meat is strong, fresh and crisp, has the name, the cultured fish has the old appearance, but the meat quality is changed, the protein is 12 percent higher than that of the common grass carp, the taste is more delicious, the fish meat has the unique characteristics of soft and smooth meat quality, crisp and unique, particularly the fish belly part is optimal, and the fish meat has toughness, so that the cooking and making are various, the raw fried slices are fried and have better taste, and the fish meat has various flavors of steaming (not steaming the whole piece), stewing, hot pot (more Guangdong people) and the like.

Crisped grass carp is crisped by mainly feeding broad beans, but the cultivation cost is high, and an economic and environment-friendly crisped grass carp cultivation technology is needed.

Disclosure of Invention

The invention aims to solve the existing problems and provides a method for culturing crisped grass carp, which comprises the steps of stimulating common cultured crisped grass carp melanocytes by using an immunostimulant to enable the melanocytes to develop and proliferate, enhancing the absorption and conversion of the crisped grass carp to nutrient components in broad beans, improving the absorption efficiency by one time compared with the common culture method, reducing half of broad bean feeding time under the condition of the same required brittleness requirement, and meeting the culture requirements of green, environmental protection, high efficiency, safety and the like.

The invention is realized by the following technical scheme:

a method for culturing crisped grass carp is characterized in that crisped grass carp is fed after broad beans are soaked in clean water containing immunostimulant for 10-25 hours; feeding times are as follows: 20-60 times; the use concentration is as follows: calculated by the total weight of crisped grass carp 50-120 mml/kg.

Furthermore, in the crisped grass carp breeding method, the crisped grass carp is fed after broad beans are put into clean water containing an immunostimulant and soaked for 20 hours; feeding times are as follows: 20-50 times; the use concentration is as follows: calculated by the total weight of crisped grass carp, is 100 mml/kg.

Furthermore, in the crisped grass carp breeding method, the immunostimulant is sodium polyamino acid and chitosan.

Furthermore, in the crisped grass carp breeding method, the crisped grass carp is fed after broad beans are put into clean water containing an immunostimulant and soaked for 20 hours; feeding times are as follows: 24 times; the use concentration is as follows: feeding crisped grass carp for 30-50 times when water temperature is lower than 25 deg.C and total weight of crisped grass carp is 100 mml/kg.

The beneficial technical effects are as follows:

compared with the prior art, the invention has the following advantages: the invention provides an environment-friendly and sustainable-development culture method for crisped grass carp, the cultured crisped grass carp is accelerated in growth speed, firm, fresh and crisp in meat quality, rich in nutrition and not easy to suffer from diseases. The common culture method disclosed by the invention has the advantages that the immunostimulant is used for stimulating melanocytes of the common cultured grass carp, so that the melanocytes are developed and proliferated, the absorption and conversion of the grass carp to nutrient components in the broad beans are enhanced, the absorption efficiency is doubled compared with that of the common culture method, half of the broad bean feeding time can be reduced under the condition of the same crispness requirement, and the culture requirements of greenness, environmental protection, high efficiency, safety and the like can be met.

Detailed Description

The present invention will be further described with reference to the following examples, which are not intended to limit the invention in any way.
