Description
Technical field
The present invention relates to a kind of black porgy rearing of fingerling, belong to cultural technique field.
Background technology
Black porgy side is flat, in oblong. Head is big, and the blunt point in front end, first dorsal has hard spine 11-12, soft bar 12. Two jaw front portions are respectively arranged with 3 pairs of gate-shaped canine teeth, are followed by very flourishing molar, and upper jaw sidepiece 4-5 arranges, lower jaw sidepiece 3-4 arranges, and hoe osseous part is respectively arranged with 3 pairs of gate-shaped canine teeth, is followed by very flourishing molar, upper jaw sidepiece 4-5 arranges, and lower jaw sidepiece 3-4 arranges, anodontia on hoe bone and palatine bone. With preopercle rear lower without squama between two. 6-7 piece of squama on side line, body cinerous, side line starting point has black patches, side often have black cross band several.
Summary of the invention
It is an object of the invention to provide a kind of black porgy rearing of fingerling, in order to cultivate better, improve cultivation efficiency and effect.
To achieve these goals, technical scheme is as follows.
A kind of black porgy rearing of fingerling, specifically includes following aspect:
(1) black porgy seed adopts indoor culture or outdoor cultivation. The cement pit of indoor 1.5-3.0 square metre is cultivated, the depth of water 1 meter. Cultivating density is 3-10 ten thousand tails/m3, and hydrostatic soil pick-up every day and change water each 1-2 time, quantity of exchanged water is the 1/2-1/3 of cement pit volume. Can also with the net cage of 1 square metre, depth of water 0.8m, under miniflow water condition cultivate, periodical blowdown and clean net cage. Outdoor cultivation, depth of water 0.7-1 rice in the native pond of 100-1000 square metre. Before cultivating fry, it is necessary to clean up the pond with bleaching powder, to kill harmful organisms in pond. Apply fertilizer about the previous week of the pool under prelarva, cultivate food organisms. The new water that note changes has to pass through filtration, with 80 order silk cover filterings or employing sand filter.
(2) food organisms and daily ration, feeding quantity: the 3rd day opening that black sea bream fry is hatched. Bait is the key factor determining larvae survival rate. Open-mouthed bait is usually the germ cell of Concha Ostreae and the little individual wheel animalcule of germling or employing high temperature cultivation thereof. With under the density of 5/milliliter, when quantity is indefinite, add and feed egg yolk, mixed bait, substantially can tide over safely the opening phase. Should be noted that the wheel animalcule thrown something and fed must with the chlorella reinforced cultivating through more than 6 hours. The feedstuff of postlarva phase is the nauplius (0.1-0.5/milliliter) of artemia, fish and shrimp gruel and mixed feed. Young stage can be thrown something and fed, and cladocera, Copepods, fish and shrimp are rotten and mixed feed. Accomplishing during bait throwing in repeatedly to throw on a small quantity, every day throws something and feeds 5-6 time.
(3) water quality: black porgy water for larval nursing requires that cleaning, fresh, salinity are with 18-25 ��, and water temperature is with about 18 DEG C, and PH7.8-8.5, dissolved oxygen amount is at 5mg/l, and ammonia-nitrogen content controls at below 0.1mg/l as well. In order to keep water quality in nursery pond pure and fresh, every day should remove dirt 1-2 time in pond. At the bottom of regular sink, refresh the water periodically and inflate. After prelarva hatching in 7-10 days, because fish body is delicate, hydrostatic should be adopted to cultivate as well. Start after 7-10 days to change water, soil pick-up, inflation. Quantity of exchanged water is gradually increased to 100-300% from 20%. Aeration quantity, starts to control have spray the water surface is micro-, is gradually increased later. Later stage can carry out running water technology.
(4) breeding density: the density of seed rearing is very big on the impact of larvae growth speed. When fry total length is when below 0.7-1cm, breeding density is with 3-5 ten thousand tails/m3As well; When total length is more than 0.7-1cm with 0.2-1 ten thousand tails/m3As well.
This beneficial effect of the invention is in that: this inventive technique is easy to cultivation black porgy, improves cultivation efficiency and the culture efficiency of black porgy, it is simple to promote the use of.
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is described, in order to be better understood from the present invention.
