Description

A kind of artificial seed's breeding method of rose Du rockfish
Technical field
The invention belongs to agriculture aquaculture Mesichthyes rearing of fingerling field, it is related to a kind of seedling of ocean benthic fishes Plant breeding method, and in particular to a kind of artificial seed's breeding method of rose Du rockfish of South China Sea.
Background technology
Rose Du rockfish (scientific names:Synanceia verrucosa) it is distributed mainly on the tropic sea of Pacific and Indian oceans Area, is mainly inhabited between the coral reef and cay on each islands and reefs periphery in the South Sea in China.Rose Du rockfish is a kind of high-grade in China Food fish, deeply by consumer is welcome because of its fine and tender taste, delicious flavour and with medical value.In recent years due to excessively catching Drag for, cause wild rose Du rockfish resources to be petered out, therefore the artificial breeding and aquaculture of development rose Du rockfish are extremely urgent, The market demand so can be both met, its wild resource can also be protected, safeguards that coral reef ecologic system is balanced, rose poison is realized The sustainable use of rockfish resource.
The content of the invention
The relevant research report of rose Du rockfish artificial seeds cultivation aspect is yet there are no, the present invention breaches rose first Artificial seed's Cultivating techniques problem of Gui Du rockfish there is provided it is a kind of reliable and can scale operation rose Du rockfish artificial seed training Educate method.
To achieve these goals, the technical scheme is that:A kind of artificial seed cultivation side of rose Du rockfish is provided Method, it comprises the following steps.
A, incubating oosperm facility:Micro-pore oxygenation equipment is installed in the m of 2m × 4 rectangle cement pit, pond;Pond is very useful black The sunshade net of color is covered.
B, seed rearing facility:The m of 2m × 4 rectangle cement sand filter;Bottom of pond spreads the fine sand of clean and white, sand Thickness is 5-10 cm;Bottom of pond places corallite 5-10 blocks;Micro-pore oxygenation equipment is installed in pond;The sunshade square of the very useful black in pond Firmly.
C, incubating oosperm and seed rearing water quality requirement:24-26 DEG C of water temperature, salinity 31-33 ‰, pH 8.1-8.4, water Flow 0.1 m/s, water depth 40-50 cm.
D, incubating oosperm:Incubating oosperm density is the ind/m3 of 2-2.5 ten thousand, through 30- under the conditions of 24-26 DEG C of water temperature 45 hours incubation of membrane.Continuous micro- oxygenation in hatching process, keeps Dissolved Oxygen in Water in 6 more than mg/L, while sooner or later daily Bottom of pond bad ovum and dirt removal is clean.
E, seed rearing:Newly hatched larvae Burden-Swimming Ability of KM is weak, floating pool water within is made gap and moved about at the middle and upper levels.Just hatch film prelarva Cultivated in former pond;Move into larvae cultivation pond after 5 ages in days to continue to cultivate, density is the ind/m3 water bodys of 0.2-0.4 ten thousand;About 20-25 days Postlarva starts metamorphosis and is changed into juvenile fish after age, and life habit is changed into bottom by swimming and dwelt, and at this moment the density domination of juvenile fish is in 500- 1000 ind/m3 water bodys.Miniflow water and continuous micro- oxygenation, keep Dissolved Oxygen in Water in more than 5mg/L during seed rearing, Bottom of pond residual bait and dead fish seedling are removed daily.
F, bait feeding:The prelarva of 1-2 ages in days relies on egg capsule nutritional development, until 2 days after-openings of incubation of membrane are ingested. Prelarva incubation of membrane starts bait throwing in material the 3rd day morning, and the food species sequencing fed is as follows:Giant clam embryonated egg → wheel animalcule → Artemia larvae → prawn larvae;The feeding volume of prelarva different growth phases is respectively:3-6 ages in days feed giant clam embryonated egg 5-6 ten thousand ind/L(Seedling water, similarly hereinafter), 5-14 ages in days feed wheel animalcule 2-3 ten thousand ind/L, 12-24 ages in days and feed artemia larvae 0.8-1 ten thousand Ind/L, 20 ages in days feed the ind/L of prawn larvae 0.1-0.3 ten thousand to pond is gone out, and feed daily 2 times.Wheel animalcule, artemia larvae and prawn The young need to feed for more than 5 hours through yeast, chlorella reinforced cultivating.Chlorella is added to nursery pond daily before 25 ages in days, it is close Spend for 2,000,000 ind/L.
The present invention is during rose Du rockfish seed rearings from giant clam embryonated egg → wheel animalcule → artemia larvae → prawn children Body, there is provided agreeable to the taste, nutritious bait, breaches rose Du rockfish seeds in initial feeding and metamorphosis as bait feeding The high problem of two critical stage death rates is developed, the survival rate of seed rearing is improved, realizes the rule of rose Du rockfish seeds Modelling is cultivated.
