Abstract
A kind of rainbow trout seawater acclimation method, which is characterized in that extend illumination using artificially feed before rainbow trout enters sea cultivation, changing the large size fingerling cultivated in fresh water physiologically to salt tolerant direction, seawater acclimation is carried out using two step transient mode of salinity later.Due to advantage of sea-farming rainbow trout in terms of flesh quality, being not take up soil, section fresh water, seed easily, people start sea-farming rainbow trout, but if misoperation, the big specification rainbow trout fingerling cultivated in fresh water can generate compared with major injury fish during taming into sea, or even will appear massive mortality.This method is smaller to the rainbow trout injury of seawater acclimation, easy to operate.
Description
Technical field
The invention belongs to aquacultures and marine resources development field, and in particular to a kind of rainbow trout fingerling by freshwater aquiculture
The method for taming seawater breeding can be used for increasing marine fish culture type, support deep open sea fish farming development.
Background technique
The yield of China's freshwater aquiculture Salmons has 4.4 ten thousand tons, mainly rainbow trout, however the Salmons of sea-farming
Yield is very low.In recent years, due to the implementation using Huanghai Cold Water Mass cultivation Salmons method, China starts to pay attention to developing salmon trout
The sea-farming of fish, meanwhile, in Huanghai Cold Water Mass sea area, cultivation Salmons also move towards far-reaching sea at China's sea-farming
Breach.
In view of sea-farming rainbow trout easily obtains in seed, flesh quality, be not take up soil, section in terms of it is excellent
Gesture, people have started sea-farming rainbow trout, still, if the big specification rainbow trout fingerling cultivated in fresh water is being tamed and dociled such as misoperation
It will appear a large amount of injuries during dissolving into sea, or even will appear massive mortality situation, therefore the salinity domestication technology of science
Just become one of the key technology of sea-farming rainbow trout production process.
Summary of the invention
The object of the present invention is to provide a kind of rainbow trout seawater acclimation methods, are difficult in the prior art with overcoming by freshwater aquiculture
Rainbow trout fingerling the deficiency of seawater breeding is arrived in domestication safely.
A kind of rainbow trout seawater acclimation method, it is characterised in that the following steps are included:
(1) when the rainbow trout fingerling specification cultivated in fresh water reaches 150g or body overall length reaches 23cm, and maximum is no more than into extra large window
When phase specification, that is, 400g, the long illumination aquaculture model for being transferred to artificially feed in 1 week by natural light is opened, i.e., is carried out before daily sunset
Artificially feed；First day light filling 1 hour extends artificially feed 1 hour daily later, when so that breeding water body illumination in one day is total
Between reach in one week 18 hours；
(2) persistently cultivated 4 weeks again after, breeding water body uses daily illumination in 18 hours, 6 hours dark periodicity of illuminations；
(3) directly the rainbow trout fingerling of cultivation is transferred in the brackish water of salinity 14 ± 2 or so again, is stopped eating, temporarily supported 1 day；
(4) then, improved with to increase the speed of 3 ‰ salinity daily and raise and train the salinity of water body, until with region breeding water body
Salinity is mutually simultaneously stopped；Period stopping feeds feed；
(5) temporarily supported 2 days under the salinity of region breeding water body again, be transferred to seawater breeding later.
The rainbow trout, including land envelope type rainbow trout and migration type rainbow trout (Salmo gairdneri) and their triploid, complete female and turn base
Because of individual.
Equipment used in the long illumination aquaculture model of artificially feed described in step (1) can be and be arranged away from cultivation water
Face is no more than the white LED lamp of the position 2m, power 0.30W/m2；
Salmons enter sea or patina and periodicity of illumination, salinity, temperature, specification (age) etc. are related.Under cultivating condition, for
The salmon trout for reaching certain specification (age) can induce adaptation seawater ring in advance by artificially adjusting periodicity of illumination and salinity
Border.
The fish such as rainbow trout and Atlantic salmon are very different in terms of salinity scanning, and the latter can after reaching certain specification
Directly enter seawater from fresh water, and rainbow trout also needs to make rainbow trout exist using environment controlling technique then in addition to needing to reach certain specification
Physiologically gradually occur just enter sea after changing in terms of adapting to seawater salinity.
Rainbow trout seawater acclimation method of the invention extends illumination using artificially feed before entering sea, makes to cultivate in fresh water
Large size fingerling is physiologically changing to salt tolerant direction, carries out seawater acclimation using two step transient mode of salinity later.This method
The advantages that smaller, easy to operate to cultured fishes injury is a kind of urgent need technology that sea-farming develops to far-reaching sea.
Specific embodiment
To cultivate rainbow trout (Salmo gairdneri) fingerling in Linyi mountain area fresh water pond, carrying out rainbow trout (Salmo gairdneri) salinity domestication in sunshine seashore pond is
Example, illustrates that the applying step of this method is as follows:
(1) from first spring next year in Winter Solstice, when the rainbow trout (Salmo gairdneri) fingerling specification cultivated in the fresh water of Linyi mountain area reaches 150g(body overall length
About 23cm) left and right when, open and the white LED lamp of the above 2m or more of water surface for aquaculture be set, power 0.30W/m2。
(2) the 1st week, LED light is opened before sunset, and increase in the 1st day artificially feed 1 hour extends artificially feed daily later
After 1 hour or so, 6 or 7 days, breeding water body periodicity of illumination reaches 18L:6D, i.e., daily solar irradiation+artificially feed duration reaches
18 hours.
(3) for 4 weeks again using 18L:6D periodicity of illumination cultivation rainbow trout (Salmo gairdneri) fingerling.
(4) utilize live fish carrier by the rainbow trout (Salmo gairdneri) fingerling cross-docking Summer Solstice or the Winter Solstice Zhaohai side salinity domestication pond of above-mentioned cultivation
In, pond salinity is 15 or so, stops eating and temporarily supports 1 day.
(5) if fish transportation vehicle water temperature differ larger with domestication sump water temperature, fish transportation vehicle water temperature slowly should be transferred in advance and
Tame sump water temperature it is close, or in advance will domestication sump water temperature be transferred to it is close with fish transportation vehicle water temperature.
(6) after, with increase daily 3 ‰ salinity speed improve domestication pond salinity, until with region cultivation water
The salinity of body is mutually simultaneously stopped, and during which stops feeding feed.
(7) temporarily supported 2 days under seawater salinity again, be transferred to seawater breeding later.
(8) if domestication sump water temperature with along sea water temperature differ larger, will should tame in advance sump water temperature be slowly transferred to and
Coastal breeding water body water temperature is close.
