Abstract
The invention discloses a method for culturing Epinephelus coioides at a low salt degree, and relates to a culturing method for aquatic livestock, in particular to a method for culturing the Epinephelus coioides. The method comprises the following steps of: desalting sea water for culturing healthy Epinephelus coioides at a rate of decreasing 0.1 to 0.2 percent of salt degree per 24 hours; and when the salt degree is desalted to 0.8 percent, putting the Epinephelus coioides into a pond in which the salt degree of the water body is 0.8 percent for culturing, wherein the salt degree of the sea water is greater than 2.0 percent. By manually desalting and domesticating gradually, a pond culturing mode of the Epinephelus coioides is optimized so that the survival rate reaches over 70 percent. The yield of the Epinephelus coioides in each pot is over 150 kilograms; and the yield of the Epinephelus coioides of each mu of the pond is 500 kilograms.
Description
[technical field]
The present invention relates to the cultural method of a kind of aquatic livestock, relate in particular to a kind of method of culturing Epinephelus coioides.
[background technology]
Grouper is cultured and cultures with shallow sea cage culture and sea pond is main; Have that strong stress resistance, growth are fast, wide temperature and anti-high-density rearing, efficiency of feed utilization advantages of higher, the scale of culturing in recent years constantly enlarges, but due to illness diseases such as viral disease, vibriosis, seawater ich are serious; The survival rate of mariculture grouper is low; The training shoot survival percent is below 10%, and the mature stage survival rate also only has 20%, seriously restricts the development of grouper aquaculture industry.
[summary of the invention]
The present invention aims to provide a kind of survival rate height, cultures the method for culturing Epinephelus coioides at low salt degree efficiently.
The method of culturing Epinephelus coioides at low salt degree of the present invention; Its seawater that will culture healthy Epinephelus coioides is with the range of decrease 1.0 ‰-2.0 ‰ salinity/desalination in 24 hours; When desalinating to 8.0 ‰ salinity; It is that culture in 8.0 ‰ pond that Epinephelus coioides is put into water salinity, and wherein said seawater salinity is greater than 20 ‰.
In preferred an enforcement, the initial salinity of pond culture water body is 8 ‰, and the salinity of water luffing is 0.5 ‰-1.0 ‰ salinity/24 hour in the breeding process, but is not less than 4 ‰; Wherein, preferably, culture with net cage in the pond culture, breeding density is 60-70 tail/m
2
Wherein above-mentioned steck net cage is built more preferably and is " worker " font or " one " font.
In one was more preferably implemented, pond culture was and other aquatic livestock mixed breed.Wherein said other aquatic livestock preferably includes Penaeus monodon, Scatophagus argus (Linnaeus) and oyster.
In another was preferably implemented, selection was healthy, body surface is normal, and body is long to be 6cm, and body weight is that the Epinephelus coioides of 8g is cultured.
Wherein, the salinity described in the present invention all refers to the mass content of salt in the water.Unaccounted other cultured key element among the present invention, like bait etc., can operate by prior art.
The present invention desalinates gradually, tames through manual work, optimizes the pond culture pattern of Epinephelus coioides, and its survival rate can be up to more than 70%.The Epinephelus coioides output of each net cage is more than 300 jin, and the Epinephelus coioides output in every mu of pond is 1000 jin.
[embodiment]
Embodiment one
1. Epinephelus coioides is desalinated specification
Select healthy, the long 6cm of being of body surface regular, body weight is the healthy Epinephelus coioides that the seawater (salinity is greater than 20 ‰) of 8g is cultured.
2. Epinephelus coioides seedling desalination mode
With the breeding seawater of above-mentioned Epinephelus coioides with the range of decrease 1.0 ‰-2.0 ‰ salinity/desalination in 24 hours to 8.0 ‰ salinity, carry out pond culture then.
The desalination process can be carried out in cement pit.
In addition, in the process of desalination, note observing ingesting of fish.Be lower than 3% like food ration, can keep salinity earlier and stop desalination, treat could continue to desalinate after normal.
3. pond culture and net cage are built
(1) complete pond has been cleared up in water (salinity is 8 ‰) suction, more than the depth of water 2.5m of pond; The salinity of water luffing is 0.5 ‰-1.0 ‰ salinity/24 hour in the breeding process, but is not less than 4 ‰.
(2) in the pond, build steck with bamboo or plank, float uses empty Plastic Drum of sealing or foams (foams are with colour bar cloth parcel), and the steck of building is " worker " font or " one " font, and every graticule mesh case specification is 3 * 3 * 2.5m.Be handled easily, can build access bridge by the side of a pond to steck net cage.
(3) breeding density is 60 tails/m
2Every breed 10-15 days, body is long, that body weight is consistent Epinephelus coioides is adjusted to same cage culture.
4. pond net box is put other breed varieties outward in a suitable place to breed and is raised together with:
Penaeus monodon and oyster: put the Penaeus monodon seedling of having desalinated (desalination salinity and pond salinity are 1.5cm with, body is long) in 15 days in advance in a suitable place to breed, and hang and support the semi-finished product oyster, reach the effect of fattening, with the utilization of raising water body and increase production and improve productivity.
The high-quality breed variety of eurysalinities such as Scatophagus argus (Linnaeus): put the Scatophagus argus (Linnaeus) seed (desalinate salinity and pond salinity together, body is long for more than the 10cm) of having desalinated after 15 days in a suitable place to breed.
5. breed result
After putting 260 days in a suitable place to breed, each net cage (but specification 3m * 3m * 2.5m) production specification is that the Epinephelus coioides output of 400-750g is more than 300 jin, the output of every mu of Epinephelus coioides is 1000 jin.
