Problems solved by technology

[0004] The digestive tract of crucian carp is short, the feed stays in the digestive tract for a limited time, and the nutrients in the feed are difficult to be completely absorbed in a short period of time, which not only leads to low reproductive performance of broodstock, poor quality of fertilized eggs, low survival rate of newly hatched fry, and no The absorbed food residues are excreted from the body, causing a large number of microorganisms to grow, polluting the environment, and easily causing diseases

Embodiment 1

[0029] In an embodiment of the present invention, a method for raising seedlings of crucian carp specifically comprises the following steps:

[0030] (1) Broodstock selection: From April to May every year, select individual female crucian carp with 32-34 lateral line scales, small head, high body, thick back, lively and strong, no injury, disease, or disability, weighing 260 grams, and an enlarged abdomen. As the female parent; choose a male carp with body length, height, back thickness, liveliness, no injury, disease or disability, weighing 620 grams, as the male parent;

[0031] (2) Breeding of broodstock: The breeding pool is 2-3 mu, the water depth is 1.6m, the broodstock are separately cultivated in the breeding pool according to the ratio of the number of males and females at 2.1:1, and 160kg per mu are stocked. 5 days before the parent stocking, use tea Disinfect the clear pond with meal powder and water; the female parents will be intensively cultivated from the first ...

Abstract

The invention discloses a crucian breeding method. The method specifically includes the following steps of parent fish selection, parent fish cultivation, artificial spawning, incubation and emergence. Nutrient-enriched feed fed in the parent fish cultivation process is prepared from, by weight, 115-120 parts of expanded corn flour, 80-85 parts of peanut meal, 55-60 parts of bone meal, 12-14 parts of chicken feather, 1.4-1.6 parts of salt, 36-38 parts of wheat germ, 48-50 parts of oyster meat, 17-19 parts of oyster shells, 0.07-0.09 part of astaxanthin, 0.16-0.18 part of zeaxanthin, 4.2-4.4 parts of palm oil, 1.4-1.6 parts of spinach extracts, 0.7-0.9 part of mulberry leaf extracts, 0.6-0.8 part of extracts of opuntia, 0.32-0.34 part of compound vitamins, 2.6-2.8 parts of garlic essential oil and 0.11-0.13 part of sodium lactate. The feed used for the method is scientific and reasonable in formula and complete and rich in nutrition, all nutritional ingredients act in a matched mode, the reproductive performance of crucian parent fish is effectively enhanced, the feed is good in palatability and easy to digest, feed intake of the crucian is greatly raised, absorption and conversion effects are greatly improved, and flesh quality is effectively improved.
