Abstract
The invention discloses a hippocampus erectus parent fish pairing method. The technical scheme of the invention is carried out under the condition of providing an aquaculture system and an aquaculture environment. The hippocampus erectus parent fish pairing method is characterized in that female sea horses and male sea horses are separately cultured for a period of time and then paired to ensure that the synchronization of incubation, the pairing rate of the sea horses is increased by mixing parent sea horses with different lengths under the condition of low density; before the parent sea horses are paired, the female sea horses and the male sea horses are separately cultured for at least 15 days until the gonads of the female sea horses are matured, and the density is 0.3-0.4/L; and after the gonads of the female sea horses are matured, and the matured female sea horses are paired with the male sea horses with the lengths of more than those of the female sea horses by 1cm, at most three pairs of sea horses are put in each vat according to the size of the culturing vat, and the specifications of the three pairs of the sea horses should contain large, medium and small specifications.
Description
Technical field
The present invention relates to close hippocampus matching technology.
Background technology
Hippocampus is traditional rare Chinese medicine.According to statistics, China's dry product that is used as medicine every year exceedes 200 tons.Because Natural Resources in China is closely exhausted, the required hippocampus import most of existing market, price raises year by year, and average price has exceeded 4000 yuan every kilogram, according to 200 tons of calculating of annual import, overbalances 800,000,000 yuan.Because hippocampus natural resources is seriously damaged, be to recover resource, many countries have carried out and have propagated research artificially in the world.As far back as nineteen fifty-seven, China carry out hippocampus culture research, past 50 years, though seedling growing process has development, large-scale production technology still produces no breakthroughs.At present, hippocampus scale artificial culture exist a common problem be close hippocampus breeding success rate low and hatching synchronism low.We find to regulate hippocampus biotic habitat is to improve the effective way of close hippocampus breeding success rate and hatching synchronism.
Summary of the invention
The object of the invention is to improve current close hippocampus matching method, provide a kind of according to the close hippocampus matching method of hippocampus life habit design, to improve the close hippocampus breeding success rate of grey hippocampus (Hippocampus erectus) and hatching synchronism.
Technical scheme of the present invention: carry out under the condition that is equipped with cultivating system and breeding environment, ash hippocampus seedling cultivating system is made up of culturing pool, culvert system, gas charging system and temperature-controlling system, during the cultivation of ash hippocampus parent population, water temperature is controlled at 24-27 DEG C, salinity is not less than 28 ‰, illumination 1000lux, miniflow water:
Before A, the pairing of close hippocampus, male and female separately cultivate at least 15 days to female hippocampus gonad maturity, density be 0.3-0.4 tail/liter, parent hippocampus is thrown something and fed with the high unsaturated fatty acid strengthening adult ' Luchung ' insect of 24 hours, and the halogen worm density of throwing something and feeding is 0.5-1/milliliter, or the freezing oppossum shrimp of throwing something and feeding, day feeding volume is 10% of hippocampus body weight, throw something and feed every day 2 times, respectively at 07:30-08:00 and 15:00 respectively once, siphon every day ight soil and dead bait 2-3 time;
B, after female hippocampus gonad maturity, match with the long male hippocampus than its large 1 centimetre of left and right of body, depending on culturing jar size, each cylinder is put at most 3 pairs, the specification of 3 pairs should have large, medium and small gradient.
The outstanding feature of this method is to match to ensure the synchronism of hatching after male and female hippocampus separately cultivates a period of time, and under low density condition, different body length parent hippocampus mixes to improve the pairing rate of hippocampus, this mode is to test and find that the synchronism that is paired into power and close hippocampus density and pairing of close hippocampus has much relations based on the present invention, and the synchronism of pairing is relevant with the synchronism of female hippocampus maturation.By this close hippocampus matching technology requirement operation, it is that the average success rate of 100%, 3 pair is generally not less than 80% that every cylinder 1-2 is paired into power to close hippocampus, and close hippocampus brooding time interval is in 2 days.Compared with random matching method, our method can improve and is paired into power more than 20%, has improved hatching synchronism simultaneously, contributes in young hippocampus large-scale cultivation and pool cultivated.
Embodiment
Implement the overall process of this method below with example explanation.
One, cultivating system
Ash hippocampus parent population cultivating system is made up of culturing pool, culvert system, gas charging system and temperature-controlling system, and culturing pool specification is generally upgraded to suitable to be no more than 400-500.
Two, breeding environment
During the cultivation of ash hippocampus seedling, water temperature should be controlled at 24-27 DEG C for good, and salinity is not less than 28 ‰, illumination 1000lux, 70 centimetres of the depth of waters, miniflow water.
Three, bait feeding
Parent hippocampus is is for example thrown something and fed, with high unsaturated fatty acid, commercially available sound rope board
the high unsaturated fatty acid strengthening adult ' Luchung ' insect of 24 hours, the halogen worm density of throwing something and feeding is 0.5-1/milliliter, or the freezing oppossum shrimp of throwing something and feeding, day feeding volume is 10% of hippocampus body weight, throw something and feed every day 2 times, respectively at 07:30-08:00 and 15:00 respectively once, siphon every day ight soil and dead bait 2-3 time;
Four, close hippocampus pairing
Before the pairing of parent hippocampus, male and female separately cultivate at least 15 days to female hippocampus gonad maturity, density be 0.3-0.4 tail/liter, after female hippocampus gonad maturity, long than the male hippocampus pairing of its large 1 centimetre of left and right with body, depending on culturing jar size, each cylinder is put at most 3 pairs, and the specification of 3 pairs should have large, medium and small gradient.By the operation of this technical requirement, it is that the average success rate of 100%, 3 pair is generally not less than 80% that every cylinder 1-2 is paired into power to close hippocampus, and close hippocampus brooding time interval is in 2 days.
