Embodiment 1

[0058] The breeding method of crucian carp in winter of embodiment 1

[0059] 1. Experimental method

[0060] [Experimental group reproduced according to the following breeding method]

[0061] (1) Disinfection of holding tanks and hatching tools: soak and disinfect holding tanks and hatching tools for 24 hours with a copper sulfate solution with a concentration of 1 mg / L;

[0062] (2) Preparation of broodstock breeding pond: Drain the water in the pond in early August, expose to the sun for 2 months, inject new water in late November, the water depth is 1.2-1.5m, and cover it with a greenhouse made of plastic film one week before the expected birth date of broodstock Keep the water temperature at 15-18°C for pools, holding pools, and hatching pools;

[0063] (3) Screening broodstock and its cultivation:

[0064] Female fish: crucian carp, 2 years old, weighing 0.5-0.6kg, 30-40 days before the expected date of delivery, put 100,000 qualified female fish into ponds with a wa...

[0131] The breeding method of embodiment 2 summer crucian carp

[0132] 1. Experimental method

[0133] [Experimental group reproduced according to the following breeding method]

[0134] (1) Disinfection of holding tanks and hatching tools: soak and disinfect holding tanks and hatching tools for 24 hours with a copper sulfate solution with a concentration of 1 mg / L;

[0135] (2) Screening broodstock and its cultivation:

[0136] Female fish: crucian carp, 2 years old, weighing 0.5-0.6kg; stock 100,000 female fish in an outdoor pond with a water depth of 3m according to the density of 100 fish / mu, and cultivate them according to the quality of fish meal: the amount of peanut bran = 1 : 1 mixed feeding female fish, once a day, 10kg / mu each time, for 20 consecutive days,

[0137] Male fish: sharp-finned carp, 2 years old, mature, weighing 1-1.5 kg, 100,000 male fish are stocked in outdoor ponds with a water depth of 3m at a density of 80 / mu, and the quality of fish meal: pean...

Abstract

The invention relates to an anti-seasonal reproduction method of crucian carp. The reproduction of crucian carp in winter includes the following steps: (1) disinfecting a temporary culture pond and ahatching tool; (2) preparing a parent fish culture pond; (3) parent fish and breeding thereof; (4) putting parent fish in the pond for temporary culture according to a male-to-female ratio and corresponding parent fish screening criteria; (5) spawning induction; and (6) fertilization and hatching. The reproduction of crucian carp in summer includes the following steps: (1) disinfecting a temporaryculture pond and a hatching tool; (2) parent fish and breeding thereof; (3) putting parent fish in the pond according to a male-to-female ratio; (4) spawning induction; and (5) fertilization and hatching. Different reproduction methods are set for different seasons, the water temperature is adjusted reasonably, and the proportion of oxytocic is set creatively. Thus, the parent fish are in a physiological state of normal ovulation or spermiation, and the vitality of reproductive cells is improved. Through the innovation of the breeding mode and the screening criteria, the problem of egg agingof female fish is solved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, and specifically relates to an off-season breeding method for crucian carp. Background technique [0002] Crucian carp (Carassius auratus Linnaeus) is widely distributed in major rivers, lakes, reservoirs and ponds across the country. It is an important economic fish in my country. Crucian carp is one of the most important aquatic products in my country because of its delicious meat, strong disease resistance, and easy feeding. The advantage is deeply loved by the majority of consumers. Crucian carp has the habit of laying sticky eggs with philodendron. During the breeding season every spring, crucian carp can naturally spawn and reproduce in natural water bodies rich in aquatic plants. However, no matter what kind of water bodies such as rivers, lakes, reservoirs, etc., the lack of aquatic plants will inevitably seriously affect the natural spawning and reproduction of carp and crucian carp, ...
