Description
Technical field
The present invention relates to the seedling growing process of the cabezon of nematode slide, be specifically related to the breeding method of a kind of cabezon fry.
Background technology
Cabezon (
sebastiscusmarmoratus) also known as brave head fish, be a kind of warm small-sized demersal fishes of warm nature, happiness inhabits many cays inshore, is distributed widely in the countries such as Japan, Korea S, Philippine littoral, and China's southern East China Sea, South China Sea.The fishing operation of cabezon as China coastal seas cay marine site and the main catches of gill net operation, in recent years, due to the continuous upgrading of sea fishery power tool and the reason such as recreational fishing is persistently overheating, caused cabezon resource day by day exhausted.Twentieth century the seventies and eighties, Japan just starts to have carried out systematic research to cabezon fry production process and artificial releasing's technology, and current the party's surface technology is ripe in Japan.From the nineties, some aquatic products research departments in the province such as Zhejiang, Dalian also have studied physiological habit and the rearing of fingerling of cabezon successively, if notification number is the patent of invention of CN101444192, disclose the process that cabezon is raised from hatching, larvae cultivation, juvenile fish, larvae cultivation disclosed in it and juvenile fish Rearing Condition are agreeable to the taste bait and change water condition, but in seed rearing process, fry lethality is higher at present, and the juvenile fish quantity of output far cannot meet domestic market demand.Study through us and find that cabezon technique of fry rearing Major Difficulties has: 1, between prelarva to postlarva period of metamorphosis, lethality is high; 2, young, the juvenile fish stage is killed and devour mutually seriously.
Summary of the invention
The object of this invention is to provide the breeding method of a kind of cabezon fry, this breeding method avoids that lethality between prelarva to postlarva period of metamorphosis is high and young, the juvenile fish stage kills and devour mutually serious problem, survival rate of fish fry is higher, can reach about 29%.
Technical problem to be solved by this invention is the breeding method of a kind of cabezon fry, and step is as follows:
A, larvae cultivation condition: cultivating every milliliter, pond water body medium and small ball algae density is 200-100 ten thousand cell number, cultivation water temperature is 10-15 DEG C, the intensity of illumination of cultivating pond is 1000lx-3000lx, larvae cultivation density is every premium on currency body 30000-50000 tail, prelarva birth age in days on the same day to 10 is thrown something and fed through the wheel animalcule of fortification between alevin stage, in every milliliter of water body, feeding volume is 8-10 every day, 10 ages in days to abnormal for throwing something and feeding through the halogen worm of fortification or moina mongolica daday during postlarva, in every milliliter of water body, feeding volume is 0.5-4 every day, from 4 age in days prelarvas, every day changes water, quantity of exchanged water starts to be 50% water body total amount, increased progressively once every 3-5 days, incremental change is 10% water body total amount, 100% is reached to quantity of exchanged water, after larvae cultivation, metamorphosis is postlarva,
B, postlarva breeding condition: prelarva all metamorphosis is after postlarva, cultivating every milliliter, pond water body medium and small ball algae density is 50-1 ten thousand cell number, cultivation water temperature is 15-18 DEG C, the intensity of illumination of cultivating pond is 3000lx-5000lx, it is every premium on currency body 8000-10000 tail that postlarva cultivates density, bait average mark every day is thrown something and fed for 3-5 time, throw something and feed when being 6 the earliest, partly throw something and feed when being 17 at the latest, every day, bait feeding total amount was 3-5% fry gross weight, the bait of throwing something and feeding is fish gruel and manufactured feed, in bait, manufactured feed weight is from 10%, every day increases progressively 5%, until the bait of throwing something and feeding is 100% manufactured feed, postlarva is cultivated after 12 days, 10-15 kilogram of shell is contained in every square metre of bottom in cultivation pond, 4-6 kilogram of (after removing weightening finish thing) Sargassum algae is contained in every square metre of underwater, the shell in cultivation pond and Sargassum algae is changed every 3 days, every day quantity of exchanged water 100%, postlarva cultivates into juvenile fish,
C, juvenile fish breeding condition: after postlarva all cultivates into juvenile fish, natural temperature and illumination, it is every premium on currency body 3000-5000 tail that juvenile fish cultivates density, bait average mark every day is thrown something and fed for 3-5 time, throw something and feed when being 6 the earliest, partly throw something and feed when being 17 at the latest, every day, bait feeding total amount was 2-4% fry gross weight, the bait of throwing something and feeding is manufactured feed, cultivate in pond and contain 15-20 kilogram of shell in every square metre of bottom, 6-10 kilogram of Sargassum algae is contained in every square metre of underwater, the shell in cultivation pond and Sargassum algae is changed every 3 days, every day, quantity of exchanged water was 100-300%, juvenile fish grows up to long 3-5 ㎝ and emerges.
Described Sargassum algae is sargassum fusifome or Sargassum horneri.
Compared with prior art the invention has the advantages that the breeding method of a kind of cabezon fry, light-operated, under temperature control and water control condition, nuisance in water body is reduced by chlorella liquid, strengthening water flea, improve the nutrition of prelarva and postlarva, reduce lethality between prelarva to postlarva period of metamorphosis, by shell and Sargassum algae, shell forms water bottom sheltered situation, large-scale suspended alga forms the concealed space of more than water bottom to the water surface, postlarva and juvenile fish can be allowed to hide, reduce killing and devouring mutually of postlarva and juvenile fish stage, improve survival rate, cabezon fry meaning survival rate can reach about 29%, tamed by manufactured feed, cabezon fry is made to adapt to manufactured feed, reduce cabezon aquaculture cost.
