Description
Technical field
The invention belongs to technical field of aquaculture, and in particular to a kind of Tilapia mossambica salt water cultural method.
Background technology
Tilapia mossambica (Oreochromis mossambila), is commonly called as African crucian, non-crucian carp, Vietnam fish, Nan Yang crucian carp etc., is subordinate to
In Perciformes, Percoidei, Callichthyidae, Tilapia mossambica category, the mouth that original refers to using Mozambique as type locality incubates non-crucian carp category fish thing
Kind:Non- crucian carp (scientific name is incubated in Mozambique mouthful:Oreochromis mossambicus), now non-crucian carp is incubated for the non-crucian carp category of Family Cichlidae and mouth
Category etc. belongs to being commonly called as jointly for several fish;Tilapia is referred to as in English.Tilapia mossambica feeding habits are extensive, are mostly based on vegetalitas
Omnivorousness, very voracious, food ration is big;Growth is rapid, especially with young stage growth faster.Growth Op Tilapia has close pass with temperature
System, 16~38 DEG C of growth temperature, 22~35 DEG C of thermophilic.It is a kind of eurysaline fishes, can all survives in sea water and fresh water;Lower oxygen concentration resistance, one
As inhabit the lower floor of water, but change with water temperature change or fish body size and inhabit water layer.
Tilapia mossambica protein content is high and be easily digested, nutritive value it is very high, enjoy " plain boiled pork salmon "
Good reputation.The whole world has a countries and regions more than 100 to carry out Rofe fish culture at present, and wherein China is Rofe fish culture big country,
The ground such as Guangdong, Guangxi, Fujian and Hainan cultivating large area.Tilapia Fillet has been the brand production in Chinese exports agricultural product
Product.
Wherein, bolti (Oreochromis niloticus) accounts for more than the 90% of Tilapia mossambica total output, from 1978
China has repeatedly been introduced since year, becomes one of Chinese main cultured fishes, its growth is fast but its salt tolerance is not strong, it is impossible in seawater
Middle cultivation, is essentially limited to the breeding production in poisons in freshwater.There are water surface area and water resource be limited, water quality for freshwater aquiculture
The problems such as being susceptible to environmental pollution, the fish crop obtained every year are difficult to meet the needs of market.Also, the Rofe of freshwater aquiculture
Fish often has bilgy odour, and flavor is not good enough.As China faces fresh water to the pay attention to day by day of freshwater resources and environmental protection, aquaculture
The situation of shortage of resources is also increasingly prominent.At the same time, China still has the low-lying Salt lake facies in a large amount of inlands.
Therefore, the method for developing the cultivation of Tilapia mossambica salt water is very important.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of Tilapia mossambica salt water cultural method, Rofe of the present invention
Fish salt water cultural method survival rate of fish fry is high, the speed of growth and freshwater aquiculture difference are little, and bilgy odour is effectively reduced.
The present invention solves technical solution used by above-mentioned technical problem:
The present invention provides a kind of Tilapia mossambica salt water cultural method, comprises the following steps:
1) Rofe fry salt tolerant is raised and train 8-10 days;
2) the Rofe fry raised and train by step 1) launches salinity control and is cultivated in 8 ‰ -12 ‰ salt water aquaculture pond;
Wherein, reduced during the Rofe fry salt tolerant described in step 1) is raised and train or stop feeding.
Preferably, step 1) improves the progress salt tolerant of salinity 0.5 ‰ -2 ‰ and raises and train daily.
Preferably, the Rofe fry initial weight described in step 1) is 5-10 grams/fish.
It is highly preferred that the Rofe fry scale, fin ray are complete, no wound is energetic.
In a kind of embodiment of the present invention, it is that cement pit is raised and train that the step 1) salt tolerant, which is raised and train, works as cement pit
Specification is 6.0m × 5.0m × 1.6m.
Specifically, step 1) is described raises and train period, keeps 26-30 DEG C of water temperature, dissolved oxygen amount 6-8mg/L.
Preferably, it is rapid 1) described in Rofe fry salt tolerant raise and train during before three/a period of time stop feed, centre three
/ start to feed for a period of time, rear 1/3rd period returns to normal feeding volume.
Preferably, during the Rofe fry salt tolerant described in step 1) is raised and train, after salinity is raised and train more than 6 ‰, slow down tame and docile
Speed is supported, the progress salt tolerant of salinity 0.5 ‰ -0.8 ‰ is improved within every 1 day and raises and train.
In a kind of embodiment of the present invention, the salt water is sea ice water and/or bittern water and/or sea salt and ground
The salt water that lower water configuration forms.
Preferably, the salt water salinity is 8 ‰ -12 ‰.
Salt water of the present invention can be dissolved in underground water by sea salt to obtain the salt water or seawater and ground
Lower water configuration forms.
Salt water salinity of the present invention is measured by WYY-1 type light refractive types salinometer.
The present invention has the following advantages compared with prior art:
1st, Rofe fry salt tolerant is raised and train and is organically combined with salt water cultivation, survival rate of fish fry is high;Avoid Tilapia mossambica
The survival rate of fish fry caused by the difference of time, space, weather etc. is low between the domestication of seedling salt tolerant and large-scale cultivation asks
Topic.
2nd, the Rofe fry salt water cultivation survival rate raised and train through salt tolerant is up to more than 90%.
3rd, Tilapia mossambica salt water cultural method fish crop disclosed by the invention is suitable with freshwater aquaculture method yield, has reality
Economic implications.After raising in 120 days, Buddhist nun sieve's Rofe of Tilapia mossambica salt water cultural method cultivation harvest disclosed by the invention
Instantaneous rate of body weight gain (IGR) and absolute gain rate (AGR) of the fish in salt water are respectively 2.1 (%/d) and 465.34 (mg/d), right
According to group, instantaneous rate of body weight gain (IGR) and absolute gain rate (AGR) in fresh water are respectively 2.12 (%/d) and 470.23 (mg/
D), the two growth differences is not notable (p ﹥ 0.05).
4th, Tilapia mossambica salt water cultural method disclosed by the invention may not only be applied to coastal area, low-lying available for China inland
Salt lake facies, especially NORTHWEST CHINA Salt lake facies Rofe fish culture;Tilapia mossambica cultured area can further be expanded, improve fish crop.
5th, compared with the Tilapia mossambica of poisons in freshwater cultivation, Tilapia mossambica salt water cultural method harvest disclosed by the invention
Tilapia mossambica bilgy odour is effectively reduced, and Tilapia flavor is good, and flesh quality gets a promotion.
Embodiment
With reference to specific embodiment, the present invention will be further described.It is to be understood that within the scope of the present invention, the present invention
Above-mentioned each technical characteristic and each technical characteristic for specifically describing in below (eg embodiment) between can be mutually combined, from
And form new or preferable technical solution.As space is limited, not repeated them here.
Survival rate, instantaneous rate of body weight gain, the calculation bibliography of absolute gain rate:Li Sifa etc. is the Changjiang river, the Zhujiang River, black
Longjiang silver carp flathead, grass carp research of fruit germplasm resource [M] Shanghai:Shanghai science tech publishing house, 1990.84-153.It is specific as follows:
Survival rate (%)=harvest number/puts number × 100% in a suitable place to breed
Instantaneous rate of body weight gain IGR (%/d)=[(lnW2-lnW1)/(t2-t1)] × 100%
Absolute gain rate AGR (mg/d)=(W2-W1)/(t2-t1)
