Embodiment 1

[0019] The artificial breeding method of wild Spanish mackerel. On May 11, two gill nets with a mesh diameter of 8.8cm, a net height of 5m, and a net length of 1500m were put into Xiangshan Harbor to catch Spanish mackerel. For brood fish, release the gillnet to the boat for about 6 minutes. The gillnet first catches two live male fish, and the gonads are relatively mature. When a male fish is caught, semen has already flowed out, so use it directly. The straw sucks the semen into the freezing tube, and the semen of another male fish is gently squeezed into the freezing tube, and the freezing tube is temporarily placed in ice for storage for later use; continue to catch broodstock, and let the gillnet flow for about 9 minutes Put the gillnets on the boat and catch two live female broodstock, but the gonads are immature; release the gillnets again for about 6 minutes and then bring the gillnets to the boat, catch one sexually mature female fish, and immediately squeeze the eggs ...

Embodiment 2

[0021] It is basically the same as Example 1, except that the time to catch broodstock is May 14th, and the gillnets are released to the boat for about 7 minutes, and 1 live sexually mature male fish and 2 sexually mature males are caught. For mature females, one of the females is immediately squeezed into the clean glass, and then the semen of the male is also squeezed into the clean glass to fertilize them; the other female is temporarily cleaned with slightly aerated clean seawater Raise for later use, after about 20 minutes of temporary raising, release the gillnet again for about 9 minutes, and catch 3 live sexually mature male fish, immediately squeeze the egg cells of the temporarily raised female fish into a clean glass, and put one Squeeze the semen of the male fish into a clean glass for artificial insemination; immediately squeeze the semen of the other two male fish into cryopreservation tubes and store them in ice cubes; if they are not caught on the same day For ...

Abstract

The artificial breeding process of wild Spanish mackerel includes capturing sexually mature parent fishes with drift net, squeezing live male fish to obtain sperm, squeezing live female fish to obtain egg cell, mixing the sperm and the egg cell in a fertilizing container with sea water via light shaking, shading the container for 3 min for artificial fertilization, washing the fertilized egg to eliminate sperm and other impurity, hatching the fertilized egg in slightly aired clean sea water at 18-22 deg.c and with salinity of 1.75-2.1 % for 40-55 hr, and culturing fish fry in clean sea water at 18-25 deg.c and with salinity of 1.75-2.1 % for 35-45 days to obtain Spanish mackerel fry. The present invention creates condition for large scale aquaculture of Spanish mackerel.

Description

technical field [0001] The invention relates to the breeding of marine fishes, in particular to the artificial breeding method of wild Spanish mackerel. Background technique [0002] East China sea mackerel (Scomberomorus niphonius) belongs to the order of perch and is an important economic fish with high economic value. The delicious taste of mackerel is deeply loved by people. The source of commercially available Spanish mackerel is mainly fishing, and the amount of natural fishing is limited, so its price is relatively expensive in the season of listing, reaching nearly 1,000 yuan per kilogram, which makes ordinary consumers have to stay away and cannot enjoy its deliciousness. Though mackerel has also been artificially cultured at present, the scale of cultivation is very small, and the output of cultivation is not large, and its main problem is due to the scarcity of fry quantity of mackerel. The breeding season of Spanish mackerel in the East China Sea is usually from...
