Description
Technical field
A kind of technical field of aquatic production of the present invention, and in particular to put-on method of Deep sea net cage fry.
Background technique
Aquatic animal is very different with living environment locating for terrestrial animal, and the viscosity of water is 800 times of air, has
Higher thermal insulation property, but dissolved oxygen is rare.Content of microorganisms in water environment is very high (> 106/ml), and many of them condition causes
Germ easily leads to the generation of disease in aquatic livestock immune deficiency.In aquaculture of aquatic animal, water temperature variation, the change of dissolved oxygen
Change, water pollution, pH value variation, harmful microbe invasion, fishing etc. all there may be stress, these stress reactions, no
But the normal growth of aquatic livestock can be influenced, and can lead to the immunity of organisms decline of fish, induces illness even death, seriously
Affect the economic benefit and ecological benefits of cultivation.
Fry dispensing is a key link in aquaculture process, and for adult fish, fry constitution is poor, raw
Life power is weaker, and degeneration-resistant disease resistance is poor, is easier to that stress reaction occurs, dead easily in launching link, survives so fry is launched
Rate and the benefit of fry quality meeting extreme influence raiser, the especially famous-brand and high-quality fish such as golden pomfret.
Summary of the invention
It is an object of the invention to overcome deficiency in the prior art, a kind of put-on method of Deep sea net cage fry is provided,
Fry can be effectively improved and launch survival rate and fry quality of link etc., improve the economic benefit and ecological benefits of cultivation.
The present invention is implemented as follows:
A kind of put-on method of Deep sea net cage fry, which comprises the following steps:
(1) seed selects:
The high-quality seed of former stock breeding is selected, seed body colour is normal, glossy, and seed is active, travelling is strong, has one
Fixed anti back-flow ability, seed body surface is complete, without it is incomplete, without damaged, no inflammation, seed individual difference is small, specification is uniform；
(2) seed is temporarily supported
Seed is placed in and is temporarily supported in aquaculture pond similar in the water quality of marine cultivation region, is cooperated using anti-stress health-care and is raised
Material is raised；
(3) seed is transported
Start within 2-3 days to stop feeding before transport, carries out primary seine daily and take exercise；1-1.5h starts to prepare fishing electrification before transporting
Water is added in the fishing electrochemical water prepared and is loaded on tank car or food bag, sealing；In tank car or the packing that fishing electrochemical water is housed
Seed is launched in bag, fish and water weight ratio is 1:11-14, and tank car opens aeration or food bag is full of pure oxygen, controls in transport
Water temperature starts to transport, and detects water temperature and water dissolved oxygen content in the transport case case at any time in transit；
(4) seed is launched
Deep water mesh cage is set in marine cultivation region, corresponding deep water mesh cage is fixedly mounted in aquaculture area,
At least one layer of etting is set on net cage, and innermost layer etting mesh diameter is less than fry diameter；Etting installation before, cleaned with
And disinfection；Fry is taken out, net cage is put into, starts to cultivate.
Wherein, the seed is golden pomfret seed.
Wherein, the anti-stress health-care mixed feed is composed of the following components in parts by weight: 15-40 parts of fish meal,
