Embodiment

[0022] Embodiment: a kind of whole year turbot artificial spawning control method, it comprises two steps of batching of broodstock and reproductive regulation of broodstock: batching of broodstock:

[0023] A total of 1,104 turbot broodstock were used in the one-year breeding cycle, including 735 females and 369 males. The broodstocks were divided into 4 groups of I II III IV. Group I had 117 females and 60 males. 124 female fishes and 64 male fishes in Group II, 358 female fishes and 172 male fishes in Group III, 136 female fishes and 73 male fishes in Group IV, and put them into four districts of the breeding pond.

[0024] The first group consisted of 117 females and 60 males,

[0025] Reproductive control method: feeding bait and carrying out specific temperature and light control respectively:

[0026]

[0027] Through reproductive regulation and spawning in March-April 2004, a total of 16.45 million fertilized eggs were obtained, with a total hatching rate of 21.3%,...

Abstract

The present invention relates to control method of year round turbot spawning. By means of the propagation control of turbot parents in different batches, the present invention makes it possible for turbot fry producing enterprise to obtain fertilized turbot eggs all the year round. The present invention features the two steps of batching turbot parents second controlling propagation period. Over 400 turbot parents are divided into four groups with at least 100 each and raised in four regions inside culture pond; and bait temperature and illumination are controlled separately, so that the turbot parents may mature and spawn separately in four different seasons.

Description

(1) Technical field: [0001] The invention belongs to the breeding technology of turbot, and is a kind of reproductive control of turbot broodstock in different batches, so that the turbot seedling production enterprise can obtain fertilized eggs of turbot in different seasons throughout the year. Control methods of artificial spawning of turbot. (two) background technology: [0002] Since turbot was introduced to China in 1992, it has achieved success in seed breeding and breeding. The breeding industry of turbot has formed in the northern coast of my country. Breeding enterprises have sprung up and developed to the south coast. Fish are raised in the south and relay cultured in the north and south, that is, large-scale seedlings in the north are purchased, and the suitable water temperature in autumn and winter in the south is used for breeding. Traditional seed cultivation is carried out in spring, and seed production has a strong seasonality. After commercial fish are gro...
