Description
Technical field
The invention belongs to Hemisalanx cultivation field, be specifically related to a kind of acclimation method improving Hemisalanx adaptive capacity to environment.
Background technology
Hemisalanx is one of famous and precious aquatic products of China, is described as on seat treasure, at home and abroad has long enjoyed a good reputation, is the focus of aquaculture in recent years.Hemisalanx is high to the dissolved oxygen amount in water and water temperature relatively common fish, always first raises the nose above water to breathe when raising together with.Hemisalanx grows the best when average temperature 8 ~ 12 DEG C, dissolved oxygen in water 8 ~ 10mg/L, when temperature is more than 20 DEG C, when dissolved oxygen in water drops to below 6mg/L, if giveing first-aid measures not in time, namely it may happen that large quantities of death in short period, bring bigger economic loss to plantation family.The mode of most Hemisalanx cultivation is directly to be invested in water to raise germ cell or fry at present, minority cultural method is put under natural conditions and is entered water again after domestication of short duration is in a few days raised, and two kinds of methods all can not well improve the probability that when Hemisalanx adapts to the ability of environment, reduction environmental catastrophe, Hemisalanx sustains damage.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of acclimation method improving Hemisalanx adaptive capacity to environment, improve the resistance when environmental factorss such as such as temperature, water body dissolved oxygen amount are changed by Hemisalanx and survival rate.
The present invention is achieved through the following technical solutions:
A kind of acclimation method improving Hemisalanx adaptive capacity to environment, comprises the steps:
(1) object choice: the selective body length healthy Hemisalanx seedling between 1 ~ 1.5cm is as domestication object；
(2) culturing pool is built: build the culturing pool that the degree of depth is 1.8 ~ 2m, area is determined according to domestication Hemisalanx quantity, it is provided with aeration system and temperature control system in culturing pool, sterilizes after injecting the deep Chi Shui of 1 ~ 1.5m in culturing pool, then put into Hemisalanx seedling with the amount of 30 ~ 40 every square metre in the water of pond；
(3) fry domestication:
A. at the 1st ~ 4 day of domestication, control pond water temperature be 8 ~ 12 DEG C, pond water oxygen content be 8 ~ 10mg/L；
B. at the 5th ~ 8 day of domestication, every afternoon 1:00 ~ 4:00, control pond water temperature be 14 ~ 16 DEG C, pond water oxygen content be 6 ~ 8mg/L, all the other time control pond water temperature be 8 ~ 12 DEG C, pond water oxygen content be 8 ~ 10mg/L；
C. at the 9th ~ 12 day of domestication, every night 6:00 ~ 10:00, control pond water temperature be 16 ~ 18 DEG C, pond water oxygen content be 5 ~ 7mg/L, all the other time control pond water temperature be 10 ~ 14 DEG C, pond water oxygen content be 7 ~ 9mg/L；
D. at the 13rd ~ 16 day of domestication, every morning 7:00 ~ 11:00, control pond water temperature be 18 ~ 20 DEG C, pond water oxygen content be 4.5 ~ 5.5mg/L, all the other time control pond water temperature be 12 ~ 14 DEG C, pond water oxygen content be 6 ~ 8mg/L；
E. at the 17th ~ 18 day of domestication, control pond water temperature be 6 ~ 18 DEG C, pond water oxygen content be 4.5 ~ 8.5mg/L.
Further, splashed in full pond by the benzalkonium bromide aqueous solution of to be working concentration the be 50 ~ 60mg/L of the sterilization described in step (2).
Further, the described temperature of step (3) controls to be completed by temperature control system, and the raising of pond water oxygen content is completed by aeration system, and the decline control of pond water oxygen content realizes by using deoxidizer.
There is advantages that the present invention is by carrying out laddering change to the water body environment condition of Hemisalanx growth of seedling, utilize the ecological plasticity of Hemisalanx seedling, improve the ability of response environment temperature and the sudden change of water body dissolved oxygen amount during Hemisalanx seedling subsequent growth, improve survival rate, Hemisalanx seedling after domestication can, water body dissolved oxygen amount lower ground district cultivation relatively big in variation of ambient temperature, promote the development of Hemisalanx aquaculture, and this acclimation method is simple to operate, with low cost, the benefit of Hemisalanx cultivation can be improved preferably.
Detailed description of the invention
