Abstract
The invention discloses a kind of cultural method of Epinephelus coioides, it is desirable to provide a kind of cultural method of efficient, environmentally safe and adult fish edible safety Epinephelus coioides.This method is first to establish indoor culture pond and biofilter, the Epinephelus coioides seed of 50 grams of weight is launched into the aquaculture pond again and feeds bait, need to control cultivating condition according to what Epinephelus coioides seedling was grown, Epinephelus coioides growth is fast, and listing is harvested after adult fish.Due to pool cultivated using indoor closed culture, fish will not escape, and cultivating condition is controlled according to the needs of Epinephelus coioides seedling growth, so Epinephelus coioides growth is fast, breeding efficiency is high；Since aquaculture pond is connected with biofilter, culturing pool returns again to aquaculture pond after flowing through biofilter filtering, can iterative cycles utilize, condition of water quality is good, and the disease of fish is few, so environmentally safe and adult fish edible safety.Present invention can apply to the cultivation field of fish.
Description
Technical field
The present invention relates to a kind of cultural method of seawater preciousness fish, particularly a kind of cultural method of Epinephelus coioides.
Background technology
Epinephelus coioides (Epinepheluscoioides) are a kind of rare precious marine products, and coastal areas of southern China each province
Important cultivation fingerling, generally uses shallow sea cage culture.But there are following main problem for this cultural method：1st, environment
Pollution causes Offshore Waters to deteriorate, and makes grouper growth slowly, disease increases, and cultured output is low；2nd, in breeding process, net cage etc. is supported
Grow facility easily to be destroyed by natural calamities such as typhoons, cause Epinephelus coioides to escape, influence cultured output；3rd, workers with long time is at sea
Open work, labor intensity is big, breeding efficiency is low；4th, the residual bait produced in breeding process, the pollution such as fish excreta and medicine
Thing is directly entered sea area, causes paralic environment more to deteriorate.Therefore existing Epinephelus coioides cultural method efficiency it is low, to ring
There is pollution in border and adult fish disease is more, edible dangerous.
The content of the invention
The technical problems to be solved by the invention be overcome the deficiencies of the prior art and provide it is a kind of efficient, to environment without
Pollution and the cultural method of the Epinephelus coioides of adult fish edible safety.
The technical solution adopted in the present invention is：The cultural method of Epinephelus coioides of the present invention comprises the following steps：
A, indoor culture pond and biofilter are established, the aquaculture pond is connected with the biofilter；
B, toward the Epinephelus coioides seed of 50 grams of weight of dispensing in the aquaculture pond, breeding density is 40~55 tails/m3；
C, chilled trash fish meat gruel or fish block are used as bait, daily bait throwing in 1 time, feeding volume is the 5~8% of fish body weight；
D, the water circulation in the aquaculture pond is driven, the cultivation water is flowed back to the cultivation again after first flowing through the biofilter
Pond, the cultivation water day internal circulating load are 6~10 times of the aquaculture pond water body volume；
E, it is 200~600Lux to control indoor illumination intensity, cultivates salinity water 20 ‰~33 ‰, and 20~32 DEG C of temperature of cultivation is molten
Solve 6~9mg/L of oxygen concentration；
F, listing is harvested after adult fish.
The optimum value of the breeding density is 45~50 tails/m3, and the optimum value of institute's art feeding volume is the 5~8% of fish body weight,
The optimum value of the cultivation water day internal circulating load is 7~9 times of the aquaculture pond water body volume, the indoor illumination intensity optimum value
For 300~500Lux, optimum value 25 ‰~28 ‰ of the cultivation salinity water, 26~28 DEG C of the optimum value of the temperature of cultivation,
Dissolved oxygen concentration ground 7~8mg/L of optimum value.
Harvest listing when the Epinephelus coioides weight is more than 600 grams.
The beneficial effects of the invention are as follows：Since the present invention first establishes indoor culture pond and biofilter, then by 50 grams of weight
Epinephelus coioides seed launch into the aquaculture pond and feed bait, according to Epinephelus coioides seedling grow needs control cultivation
Condition, Epinephelus coioides growth is fast, and indoor culture pond is totally-enclosed, and fish will not escape, so breeding efficiency is high；Due to cultivation
Pond is connected with biofilter, culturing pool flow through biofilter filtering after return again to aquaculture pond, can iterative cycles utilize, water quality
Condition is good, and the disease of fish is few, so environmentally safe and adult fish edible safety.
