Abstract
A kind of Grouper cultivating method, comprises the following steps：（1）, place election；（2）, throw seedling；（3）, bait throwing in, feed coefficient fluctuation 6 10.The Grouper cultivating method of the present invention, launched by carrying out the strictly science of regulation and bait to water quality so that the grouper speed of growth is fast, no disease and pests harm, and meat is good, and yield is high.
Description
Technical field
The present invention relates to the cultural technique of aquaculture technical field, more particularly to grouper.
Background technology
Black fish for cats is grouper, and coastal local resident is commonly called as.Life stone seam gap by the sea, there is the title of marine carp, it is real
Edibility and taste are higher than carp on border, partially more expensive than Common Fish price.Grouper is nutritious, and fine and tender taste is pure white, class
Like chicken, the title of " extra large chicken " is known as.Grouper is a kind of low fat, the first-class food fish of high protein again, is pushed away by Hong Kong and Macao
For one of four big fishes of China.
Traditional Grouper cultivating method, survival rate is low, slow-growing, yield poorly, meat it is undesirable.
The content of the invention
In order to solve above mentioned problem existing for traditional Grouper cultivating method, the invention provides a kind of excellent grouper
Cultural method.
The used to achieve the above object technical scheme of the present invention is：A kind of Grouper cultivating method, including following step
Suddenly：
（1）, place election, select the time of low water depth of water should more than 4 meters, winter minimum water temperature be not less than 15 DEG C, pH value 7~9 is molten
Marine site of the oxygen amount more than 5 mg/litres；
（2）, throw seedling, throw seedling specification be：One 3 × 3 × 3 meters of net cage, putting every case of the fingerling specification below 50 grams/fish in a suitable place to breed can
Launch 2000-3000 tails, every case 800-1200 tail of the specification below 150 grams/fish；
（3）, bait throwing in, feed coefficient fluctuation in 6-10；
The step（2）In, one 3 × 3 × 3 meters of net cage, putting every case of the fingerling specification below 50 grams/fish in a suitable place to breed can launch
2500 tails, every case 1000 tail of the specification below 150 grams/fish.
The step（3）In, the main feed fed is small fish, and daily ration of feeding typically rests in the 7- of fish body weight
9%。
The Grouper cultivating method of the present invention, launched by carrying out the strictly science of regulation and bait to water quality so that
The grouper speed of growth is fast, no disease and pests harm, and meat is good, and yield is high.
Embodiment
The Grouper cultivating method of the present invention, place election：Wind sheltering condition is good, and wave is little, not by typhoon；It is sandy
Preferably, the time of low water depth of water should be more than 4 meters, and winter minimum water temperature is not less than 15 DEG C, 22 DEG C~28 for bottom, gravel matter bottom, reef matter bottom
DEG C water temperature number of days is no less than 200 days；Water quality is pure and fresh, suitable salinity 25~32 ‰, pH=7~9, dissolved oxygen amount 5 mg/litres with
On, pollution-free region.Breeding density and the flow velocity of mariculture area have very big relation, and the unobstructed sea area of flow velocity can be larger, on the contrary
The net cage of less general one 3 × 3 × 3 (rice) is wanted, a 2500 tails left side can be launched by putting every case of the fingerling specification below 50 grams/fish in a suitable place to breed
The right side, every case 1000 tail of the specification below 150 grams/fish or so.That is the cage culture yield of one 3 × 3 × 3 (rice)
200 kilograms or so are appropriate.The main feed fed is the higher small fish of freshness.Typically according to the big of grouper
It is small, fed after small fish is cut into suitable size with fish cutter.Because the species of feed fish is different, coefficient fluctuation is fed in 5-
12.Feeding technology is larger to the influential effect of Grouper cultivating.Under the environmental condition of 25 DEG C of water temperature, the digestion rate of grouper
About -24 hours 20 hours.So grouper is fed once daily in South China Sea May-October, typically at the morning 9-
Carried out when 11.November-December, every two days of March-April feed once, and winter ocean temperature is down to less than 20 DEG C and fed for -4 days 3 days
Once.The 3%-5% of each feeding volume about percentage of liveweight, when water temperature is suitable feeding amount more greatly, feeding amount when water temperature is relatively low or too high
Reduce.In production, feeding amount typically is determined depending on the feeding state of grouper, as degree when weakening using appetite.That feeds is general
Principle is that the slow water of small tidal water flow is clear, throws more when water temperature is suitable, throws less on the contrary.Daily ration of feeding typically rests in 8% left side of fish body weight
The right side, when feeding every time, should first put into little Xu, in batches slowly float, wait rob eaten before spill next group again after batch feed, until fed to appetite
Untill not robbing food, never feed can once be poured into net cage, in order to avoid causing feed waste and pollution environment, grouper never eats
The food sunk to the bottom.Because the grouper mode of swallowing is fed, therefore the Individual Size of bait is less than the bore of fish.Feed also
It should be particular about and determine matter, quantitative, timing principle.It should also be noted that setting up feed table in pond culture, fixed point feeding is carried out, to improve feed
Utilization rate and be convenient to clean defective material, keep the good of water quality.
The present invention is described by embodiment, and those skilled in the art know, is not departing from the spirit of the present invention
In the case of scope, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, in the religion of the present invention
Lead down, these features and embodiment can be modified to adapt to the essence of particular situation and material without departing from the present invention
God and scope.Therefore, the present invention is not limited to the particular embodiment disclosed, and falls with claims hereof
In the range of embodiment belong to protection scope of the present invention.
