Problems solved by technology

The main problem of wild seahorses as parents is that they die in large numbers due to changes in habitat, surface parasites, and intestinal bacteria. The survey results show that if wild seahorses are not properly domesticated, their mortality rate in the breeding process is as high as 85%. The pairing success rate and mating frequency of wild seahorses are very low. At the same time, the gestation cycle is significantly affected by the interference between wild seahorse parents, which affects the survival rate of offspring larval seahorses.
However, so far, there is no special report on the domestication and breeding of wild seahorses in the international scope

Embodiment

[0020] From April to May in 2009, 2010 and 2011, wild seahorses, three-spotted seahorses, barbed seahorses and striped seahorses were successfully domesticated.

[0021] In April 2009, 100 wild spiny seahorses were collected from Beihai, Guangxi, and they were divided into 5 holding pools for domestication (20 in each pool). The tail achieved normal mating (95%).

[0022] In May 2010, 100 large seahorses and 60 lined seahorses were collected from Hainan, and domesticated and raised respectively. As a result, 91 large seahorses survived within 2 months, and 82 of them participated in mating and produced offspring (the mating success rate was 90%); 54 lined hippocampus survived (90% survival rate), and 52 participated in mating within 2 months.

specific example

[0024] In April 2011, 120 wild three-spotted seahorses were collected from Hainan, immersed in 5 ppm nitrofurazone water for 12 hours, and the seahorses were divided into 6 ponds (70×80×90 cm) on average for breeding, of which 3 ponds were domesticated In the experimental group, 3 pools were used as the control group (under the premise of ensuring water quality and aeration, without step-by-step domestication treatment). In each group, the temperature was 25°C, the salinity was 34‰, and the dissolved oxygen was 6.7 mg / L. On the 1st to 2nd day, adult Artemia worms were fed twice a day, the pond was inflated with a large amount of air, the water was not changed, and the light intensity was 500 Lux; on the 3rd to 7th day, a small amount of adult Artemia and a sufficient amount of frozen mysis were fed 3 times a day. Put EM bacteria once every 2 days, and the light intensity is 1500 Lux; on the 8th to 13th day, feed frozen mysis 3 times a day, use circulating water in the pool, re...

Abstract

The invention discloses a method for domesticating and breeding wild hippocampus. Mainly aiming at the problem of high death rate of wild hippocampus parents at present, the method is used for efficiently domesticating and managing the wild hippocampus, so that the death rate of the wild hippocampus parents can be remarkably reduced, and the mating success rate of the hippocampus and the survivalrate of the descendant young hippocampus can also be improved. The efficient and convenient method is provided for commercial culture of the hippocampus, and the method has important economic value.

Description

technical field [0001] The invention relates to the technical field of seahorse breeding, in particular to a domestication and breeding method for wild seahorses. Background technique [0002] Seahorse farming is currently a hotspot in international mariculture, and the initial source of seahorse farming is mainly wild-caught seahorses. The main problem of wild seahorses as parents is that they die in large numbers due to changes in habitat, surface parasites, and intestinal bacteria. The survey results show that if wild seahorses are not properly domesticated, their mortality rate in the breeding process is as high as 85%. The pairing success rate and mating frequency of wild seahorses are very low. At the same time, the gestation period is significantly affected by the interference between wild seahorse parents, which affects the survival rate of offspring larval seahorses. However, so far, there is no special report on the domestication and breeding of wild seahorses int...
