Embodiment 1

[0016] test group:

[0017] From April to June 2013, at the seahorse breeding base of the South China Sea Institute of Oceanography, Chinese Academy of Sciences, Shenzhen, Guangdong Province.

[0018] (1) Screening of broodstock

[0019] After the seahorse reaches 6 months or more and the sexual maturity rate of the female broodstock reaches more than 20%, that is, during the breeding period, the screening of male and female broodstock begins. According to the ratio of female to male of 1:2, 300 spare seahorse broodstock were selected and put into 2 cement ponds (length*width*height=3m*6m*1.2m) for temporary breeding of male and female.

[0020] Select male and female parents according to the following criteria

[0021] Male parent fish: Select seahorse male fish with body length longer than 12cm, round body surface, good vitality, active feeding and high estrus rate as parent fish. When the male fish is in estrus, the performance is as follows: the snout is close to the ab...

Abstract

The invention discloses a method for improving synchronous mating of seahorses. Due to adjustment on comprehensive factors, such as parent screening (a plurality of seahorses parental populations with a consistent sexual maturation period are screened and separated out according to the sexual maturation degree), domestication and breeding equipment improvement and parental physiological characteristic observation, in a seahorse breeding process, parent seahorses can be promoted to form a stable periodic reproduction for mating, gestation, parturition and remating, so that the parturition rate in the reproduction peak period (a single week) is over 60 percent, and the reproduction efficiency of the seahorses can be effectively improved by over 10 percent.

Description

Technical field: [0001] The invention belongs to the field of hippocampus breeding methods and technologies, and in particular relates to a method for improving synchronous mating of hippocampus. Background technique: [0002] Seahorses are fish that spawn multiple times a year, with a short spawning cycle (15 to 30 days) and a small number of single spawns (100 to 1,000). The reproductive behavior of seahorses is special, and the fertilized eggs hatch in the brood pouch at the rear edge of the abdomen of male seahorses before living independently. Large-scale cultivation of seahorse seedlings must rely on the simultaneous breeding of a large number of broodstock. In the conventional seahorse nursery process, the breeding cycle of different seahorse broodstocks is uncertain, the spawning time of broodstocks is not synchronized, and the number of broodstocks fluctuates greatly. Producers cannot arrange the production facilities and bait required for fry cultivation in a tar...
