The number ratio of the male fish to the female fish is 2-3: 1.
2. Stocking and breeding the parent fishes:
placing the selected breeding fishes into a temporary culture cement pond, wherein the density is 100 plus 150 fish per square meter, the water depth is 40-60cm, and the water temperature is controlled to be 15-25 ℃. After the breeding fish enters the pond, slowly feeding the breeding fish for 1-2 days, wherein the bait is combined by granular feed and limnodrilus, the feeding amount accounts for about 3-5% of the weight of the breeding fish, and water is injected and changed once every 3 days during the breeding period.
3. Preparing an oxytocic drug: the oxytocic is 15ug of ovulation promoting agent 2 and 15mg of diulon per kg, and the male fish is 1/2 female fish.
4. Hastening parturition: injecting the oxytocic prepared in the third step into the muscle at the base of dorsal fin of the parent fish, and separately putting the injected parent fish into the temporary rearing pond; and raising the temperature of the temporary culture pond to 20-25 ℃.
5. Artificial insemination: and (3) extruding egg granules from female fish 20-28 hours after induced spawning, mixing the eggs and the sperm, and performing dry fertilization to obtain fertilized eggs.
6. Hatching: and (3) carrying out oxygen-enriched incubation by using pure water, wherein the water temperature is 18-23 ℃, a sunshade net is arranged above the incubation pool for shading treatment, the dissolved oxygen in the water is kept at more than 5mg/L, and dead eggs are removed every day during incubation. And (3) injecting and changing water once a day, injecting and changing water 2-3 times a day after 3 days, and culturing the fries in a cement pond after the fries are black. And (4) the accumulated temperature of rhodeus in the incubation period needs 36-45 days, and the fries of spodoptera spongiensis are obtained after 13-15 days.
The invention has the advantages that:
the invention mainly solves the complicated problems that the existing bitterling seedlings need to be fished in a natural water area, or mussels need to participate in artificial spawning, and the like. The artificial breeding technology for bitterling the rhodeus bitterling is successfully summarized, freshwater mussels are not needed in the technology, the technology reduces the environmental requirement, the whole technical process is implemented in a controllable range, the influence of the external environment is small, the operation is convenient and reliable, the difficult problem of fry production of the bitterling the rhodeus bitterling is well solved, and the method has important significance for wild resource protection and large-scale cultivation of the bitterling the rhodeus bitterling. By applying the technology, the sponginess rate of rhodeus bitterling is over 80%, the fertilization rate is over 80%, the hatching rate is over 80%, and the survival rate of seedlings is over 60%.
Detailed Description
Example one
An artificial breeding method of rhodeus bitterling comprises the following steps:
1. collecting breeding fishes:
collecting wild female fish: the body length is 6-12 cm, the weight is 5-15g, the body is born for three years, and the abdomen has an oviduct; the male fish has a length of 5-10cm, a weight of 5-15g, two years old, a colorful and fresh body, the head, mouth and eyes have star-chasing, and the number ratio of the male fish to the female fish is 2: 1.
2. Stocking and culturing parent fishes:
placing the selected breeding fish in a temporary culture cement pond, wherein the density of the breeding fish is 100-2The water depth is 40 cm, the water temperature is controlled at 15-20 deg.C, after 1-2 days, feeding bait for the breeding fish, the bait is composed of artificially prepared granular feed and limnodrilus, the input amount is 3-5% of fish weight, and water is changed every 3 days during the cultivation period.
3. Preparing oxytocic and hastening parturition
The oxytocic is mixed with 15ug of ovulation-promoting hormone 2 and 15mg of diohuone per kilogram to prepare the oxytocic, the dosage of the male fish is 1/2 of the female fish, the prepared oxytocic is injected into the muscle at the base of the dorsal fin of the parent fish, then the female and male fish are separated and put back into a temporary culture pond, and the water temperature is 20-25 ℃.
