The invention discloses a seawater domestication method for Daphniopsis tibetana Sars, which comprise the following steps: disinfecting the culture container, culture container being opaque in periphery; concocting culture liquor, taking disinfected and filtered seawater to adjust pH value to 7-8, temperature 10-15 degree, salinity 10-15, selecting Daphniopsis tibetana Sars and placing it in container, culturing it with above-mentioned liquor, illumination intensity 1000-2000Lx, photoperiod 14D:10L, feeding with Chaetoceros sp. feedstuff, feeding volume 30x105cell/ml, selecting healty, activefemale Daphniopsis tibetana Sars which has produced baby Daphniopsis tibetana Sars and is 2-3 mm in body length, feeding it with algae liquid selecting one or two kinds from Chaetoceros sp., Dunaliella salina, Isochrysis galbana, chlorella, feeding density 30x105cell/ml, inoculating Daphniopsis tibetana Sars density 100ind/l, observing Daphniopsis tibetana Sars growth state and water body to partly for wholly substitute for Artemia and promote fish fry survival rate, reduce the seedling-breeding cost.
Description
Technical field:
The present invention relates to a kind of seawater domestication and culture method of daphniopsis tebitana sars.
Background technology:
Daphniopsis tebitana sars (Daphniapsis tibetana Sars, 1903) be subordinate to Magna section (Daphniidae) and intend Magna genus Daphniapsis, mainly be distributed in ground such as China Tibet, Qinghai, Xinjiang, be distributed in the former Soviet Union, India, Pamir (syn.Daphniapamiresis Rylov), Iran's (syn.Daphnia fusca Gurney) and antarctic zone (syn.Daphnia studerri R ü he) abroad, it is a kind of cold water salt solution cladocera, the natural temperature of its distribution is-2～18 ℃, salinity 9～35, pH9～10.4.Because daphniopsis tebitana sars happiness low temperature and anti-than high salinity, be fit to high height above sea level, high and cold, oligotrophic water's body life, can become new living bait in northern marine fish, shrimp and the crab cultivation, especially current seafood fish is grown seedlings and is produced relaying and need a large amount of artemia naupliis with wheel animalcule afterwards as open-mouthed bait, the artemia cysts resource-constrained, and (50～600,000 yuan per ton) cost an arm and a leg, therefore partly or entirely substitute the halogen worm with daphniopsis tebitana sars, just can improve survival rate of seedling, reduce the marine fish seedling cost, have very big society and economic implications.But up to now, also with seawater (salinity 30～35) daphniopsis tebitana sars is not carried out a large amount of artificial culture, utilization at northern marine fish mating season (4～June).
Summary of the invention:
The present invention is in order to solve existing in prior technology the problems referred to above, provide a kind of can be at northern marine fish mating season (4～June), with the artificial a large amount of daphniopsis tebitana sars of cultivating of seawater, partly or entirely to substitute the halogen worm, improve the seawater domestication and culture method of the daphniopsis tebitana sars of survival rate of fish fry, reduction albacore seedling cost.
Technical solution of the present invention is: a kind of seawater domestication and culture method of daphniopsis tebitana sars is characterized in that having the following steps:
A. to the culture vessel sterilization, be opaque shape around the culture vessel;
B. water is cultivated in allotment: cancel malicious filtering sea, adjusting seawater pH is 7～8, and 10～15 ℃ of temperature, salinity are 10～15;
C. choose kind of a Magna: the daphniopsis tebitana sars of gathering is placed the described culture vessel of a step, cultivate with the described cultivation water of b step, intensity of illumination is 1000～2000Lx, and periodicity of illumination is 14D:10L, and with bait feedings such as Chaetoceros muelleris, feeding volume is 30 * 10
5Cell/ml, choosing had been produced after 1～2 nest children Magna, body length is kind of a Magna at 2～3mm, the active healthy female Magna that moves about;
D. cultivate:
With the described culture vessel of a step, inject the algae liquid of culture vessel volume 1/5～1/4, described algae liquid is to add in Chaetoceros muelleri, Dunaliella salina, ball Isochrysis galbana, the chlorella one or both to form in the described cultivation water of b step, density is 3 * 10
5Cell/ml, the density of inoculation daphniopsis tebitana sars is 100ind/l;
Intensity of illumination is 1000～2000Lx, and periodicity of illumination is 14D:10L, throws something and feeds with one or both replacements of trying to gain in Le Shi Chaetoceros, Dunaliella salina, ball Isochrysis galbana, the chlorella, and feeding volume is 3 * 10
5Cell/ml throws something and feeds twice every day;
Primary stage of inoculation was changed water once every 3～4 days, after density reaches 500ind/l, changed water once in 1～2 day, and each quantity of exchanged water is 2/3 of the former water yield;
The kind Magna of inoculation removes kind of a Magna after producing 1～2 nest children Magna, treats that newborn young Magna becomes after age 15～18 days, removes new breeder mother Magna, and the culture density that guarantees newborn young Magna is at 450～550ind/l, and becoming the culture density of Magna in age is 100～200ind/l;
E. gather: reach 2000～2500/liter when cultivating Magna density, gather.
Culture vessel is glass jar or plastics tank in the described a step, is 10%HCl solution soaking at least 6 hours with concentration, rinses well with fresh water then, blocks with opaque cloth or paper around glass jar or the plastics tank.
The salinity of described b step is that coastal seawater is allocated gained through sand filter, precipitation and 20 μ m silk cover filterings and the running water behind aeration, allotment back inflation 3～5h.
Described b step is to use NaHCO
3With HCl be that the pH of the dilution seawater of 10-15 is transferred to 7～8 with salinity, basicity is adjusted to 7～12mmol/l.
Described b step is the NaHCO that every premium on currency is added 0.6～1.0g
