Abstract
An efficient cultivation method of a turbot family offspring comprises the following steps: parent fish selection, parent fish cultivation, artificial directional mating, hatching, offspring cultivation and getting of commercial offsprings. The parent fish is selected from germplasm parent fish of different batches from different countries; artificial fertilization is performed among different germplasm parent fish, and the same batch of the parent fish are not allowed to mate with each other; offspring cultivation is as follows: at the early period, the adopted facility is a 3m<3> glass reinforced plastics barrel, and bait comprises chlorella, rotifer and artemia; at the middle period, the adopted facility is a 10m<3> cement pond, and the bait is micro pellet bait; at the later period, the adopted facility is a 20-30m<3> cement pond, and the bait is fish larvae pellet bait; and specification of the commercial offsprings is 5-6cm. The method is characterized by adopting the parent fish with different germplasm resources for the artificial directional mating, and seriously controlling inbreeding; and adopting different culturing facilities to cultivate the offspring by three stages, which causes the offspring emergence rate of the commercial offspring to reach 46.8%, and improves growth rate thereof by 36%, and lowers of etiolation rate thereof below 5%. The method can efficiently produce high-quality turbot offsprings, and is applicable to large-scale production.
Description
Technical field:
The invention belongs to turbot and culture fry production process, is in the large-scale production of turbot seed, and efficient, high-quality is cultivated a kind of technical method of seed.
Background technology:
Turbot (Scophthalmus maximus L.) is northeast, the Atlantic Ocean, the coastal distinctive a kind of flatfish in Europe.China introduced the turbot seed from Britain first in 1992, tame, form, aspects such as parent fish rearing, seed production, nutrient fodder, disease control and basic research have obtained serial important research achievement." biological property of turbot and the seed production key technology " of, Lei Jilin strong etc. (Marine Sciences/2004 year/the 28th/the 3 phase of volume) as: Inst of Huanghai Sea Marine Products, Chinese Academy of Aquatic Product Science's door, among the grandson of Inst of Huanghai Sea Marine Products, Chinese Academy of Aquatic Product Science " test of turbot industrial aquaculture " (ocean research/2004 year/the 24th/the 1 phase of volume) and the Zhang Zheng of life institute of Chinese Marine University etc. " culturing evaluation and the phylogenetic systematics research of turbot fin rot pathogen " (Marine Sciences make progress the/2004 years/the 22nd rolled up for/the 2 phase) etc.They have mainly carried out a large amount of research work at aspects such as turbot fundamental biological knowledge characteristic, fry production process, breeding production and disease controls.Because the parent population of adopting in the turbot seed production process is usually without the science seed selection, for many generations culture and inbreeding in addition, cause the germplasm degradation phenomena of offspring seed more serious, occurred that incubation rate and emergence rate reduce, proterties degradation phenomenas such as growth rate slows down, resistance variation.At present, in the turbot seed produces, adopt the inbreeding control technology to carry out scale fry of turbot family High-efficient Production, still do not have the research report.
Summary of the invention:
The purpose of this invention is to provide that a kind of technology is simple to operate, the parent population of adopting different germplasms, the method for setting up inbreeding control scheme, artificial orientation's mating, the High-efficient Production fry of turbot family is applicable to large-scale production.
The present invention finishes by following technology operation sequence: its technology contents comprises: 1, parent population is selected, and 2, parent fish rearing, 3, artificial orientation's mating, 4, hatching, 5, seed rearing, 6, commercial seedling.
1, parent population is selected:
Choose 4～6 batches of germplasm parent populations that derive from Britain, France, Denmark, Spain, Norway and Chilean different batches, every batch of parent population quantity 50～80 tails, male female ratio is 1:1 or 1:1.5; 3 age～4 ages of raun, 3～5 kilograms of body weight, long 40～60 centimetres of body, 2～3 ages of milter, 2～3 kilograms of body weight, long 30～35 centimetres of body.
2, parent fish rearing:
Daily management: water is the sand filtration seawater; Light daytime is 1000LUX～1500LUX, and be nature evening; Water temperature: 8～18 ℃, salinity: 28～35; PH7.8～8.5; Dissolved oxygen〉6mg/L; Ammonia nitrogen＜0.2mg/L; The day exchange capacity of flowing water is 2～6 full doses; Parent fish rearing density is 5kg/m
