Embodiment 1

[0013] In the reproductive season, select the cultured broodstock that are robust and lively, and whose gonads have developed to stage IV. Broodstock body length 10.5 ~ 13.0cm, weight 17.3 ~ 32.0g. The abdomen of the female broodstock is enlarged, and the urogenital papillae are bright red in round shape; the urogenital papillae of the male broodstock are triangular. The age of broodstock is 1 to 2 years old. Spawning pool area 10m 2 / mouth, the depth of the pool is 1.5m, and the bottom and walls of the pool are covered with black ceramic tiles to avoid scratching of broodstock. The pool surface is shaded with sunshade nets to maintain a low-light environment. The spawning pipeline is made of ceramic material, and the pipeline is 50cm long, 9.5cm wide, and 7.5cm high. Divided into upper and lower parts, the inner wall of the upper part is rough, which is conducive to the attachment of fertilized eggs; the inner wall of the lower part is glazed smooth, which is conducive t...

Embodiment 2

[0023] Wild broodstock that are strong and lively, and whose gonads have developed to stage IV are selected during the reproductive season. Broodstock body length 10.0-12.2cm, weight 17.0-28.5g. The abdomen of the female broodstock is enlarged, and the urogenital papillae are bright red in round shape; the urogenital papillae of the male broodstock are triangular. Broodstock age is 1-2 years old. Spawning pool area 5m 2 / mouth, the depth of the pool is 1.5m, and the bottom and walls of the pool are covered with black ceramic tiles to avoid scratching of broodstock. The pool surface is shaded with sunshade nets to maintain a low-light environment. Oviposition pipeline is with embodiment 1.

[0024] 1. Parent fish ripening: Same as Example 1, divided into 3 groups for comparative experiments, the results are shown in Table 3, the ripening rate of 2 injections of mixed hormones can reach 65%, while the ripening rate of 1 injection of single hormones is only 45.0% (LHRH-A 3...

Embodiment 3

[0030]In the reproductive season, select the tidal flat seine breeding broodstock that are robust and lively, and whose gonads have developed to stage IV. Broodstock body length 10.2-12.8cm, weight 17.1-31.0g. The abdomen of the female broodstock is enlarged, and the urogenital papillae are bright red in round shape; the urogenital papillae of the male broodstock are triangular. Broodstock age is 1-2 years old. Spawning pool area 10m 2 / mouth, the depth of the pool is 1.5m, and the bottom and walls of the pool are covered with black ceramic tiles to avoid scratching of broodstock. The pool surface is shaded with sunshade nets to maintain a low-light environment. Oviposition pipeline is with embodiment 1.

[0031] 1. Parent fish ripening; same as Example 1, divided into 3 groups for comparative experiments, the results are shown in Table 5, the ripening rate of 2 injections of mixed hormones can reach 70.0%, while the ripening rate of 1 injection of single hormones is only...

Abstract

An artificial reproduction method for bluespotted mudhopper includes such steps as providing harmone LHRH-A3 and / or HCG, injecting the harmone into the parent bluespotted mudhopper, using the sex pheromone to induce the mating and ovipositing of parents in oviscapt, artificial fertilization by semi-drying method, washing with clean seawater and innoculation.

Description

technical field [0001] The invention relates to an artificial breeding method for fish, in particular to an artificial breeding method for large mudskippers. Background technique [0002] The big mudskipper (Boleophthalmus pectinirostris) belongs to the order Perciformes, the suborder Gobiodei, the family Periophthalmidae, and the genus Boleophthalmus. The big mudskipper is distributed in China, North Korea, Japan, Myanmar and the Malay Peninsula, and in China, it is mainly distributed in the coastal areas of Jiangsu, Zhejiang, Fujian, Taiwan, Guangdong and Guangxi. Mudskippers inhabit mudflats and mangrove areas in the intertidal zone of estuaries and harbors. They are warm-water, wide-temperature, and salty cave fish. Their juveniles and adults mainly feed on benthic diatoms. They have short food chains, few diseases, and high survival rates. It has the characteristics of high production cost, low cost of breeding, convenient management, no pollution to the environment an...
