Abstract
The invention discloses a method for rapidly determining inflation of seawater fry swimming bladders. 10-25days after fries hatch, 12-18mg/L of anesthetic Aqui-S is adopted; detecting density is 100 fries in 100 ml of water, and anesthesia time is 5-8 minutes generally; when the fries are in the state of being unable to swim, swinging bladders of the fries floating on the water surface are inflated fully, the swinging bladders of the fries staying in water are partially inflated, and the swinging bladders of the fires sinking at the bottom of the water are not inflated. The method is simple and capable of rapidly determining whether the fry swimming bladders are fully developed or not and inflate or not, and is adaptable to promotion and application.
Description
Technical field
The invention belongs to technical field of fishery, relate to a kind of method whether quick judgement seawater fry air bladder is inflated.
Background technology
Have gas in air bladder, gas componant is oxygen, nitrogen, and deep-sea is greater than shallow sea and is greater than fresh water, and in fish, pipe fish glue class adopts the venting of pneumatic duct, red body, and pneumatic duct is vented, and physoclistous class is then exitted with red body, oval window air-breathing; Fish glue has the effect regulating proportion.In the nursery of fish indoor industrially, air bladder unaerated phenomenon ubiquity, whether fry air bladder is inflated not only can affect seawater fry quality but also can have influence on production cost.Experiment proves, the fry growth of air bladder unaerated is slow, and growth cycle is long, and survival rate is low, and aquaculture cost is high.This is mainly because the fry of air bladder unaerated can consume the maintenance of more the energy position of fish body in water, balance etc. usually.If can detect rapidly in early days and isolate the Juvenile fish of fish glue unaerated, production cost can not only be reduced, enhance productivity, and can improve the later stage and to emerge quality.After larval development, body surface is covered by skin or scale, is therefore difficult to judge whether air bladder is inflated from outward appearance.
Summary of the invention
The object of the invention is to the defect overcoming the existence of above-mentioned technology, a kind of method providing quick judgement seawater fry air bladder whether to inflate, is a kind of simple and easy, the method judging whether fry air bladder grows completely, whether inflate fast.
Its concrete technical scheme is:
The method whether quick judgement seawater fry air bladder is inflated, at fry hatching membrane 10-25 days, the anaesthetic of employing is Aqui-S, measures as 12-18mg/L; Density measurement is 100 ml water 100 tail fries, the general 5-8 minute of anesthesia duration, and when fry is in the state that can not initiatively swim, on bubbling through the water column, then air bladder is inflated completely, if in water, air bladder partial inflation, is sunken to the bottom then air bladder unaerated.
Further preferably, anaesthetic add fry cylinder before should with seawater premix, then add nursery cylinder.
Further preferably, note inflation in nursery cylinder, prevent ischaemia.
Compared with prior art, beneficial effect of the present invention is:
The method of the invention can detect rapidly in early days and isolate the Juvenile fish of fish glue unaerated, can not only reduce production cost, enhance productivity, and can improve the later stage and to emerge quality.
Embodiment
Below in conjunction with specific embodiment, technical scheme of the present invention is described in more detail
Statistical method: treat after adding anaesthetic that fry is anaesthetized, gets 50 prelarvas detect under anatomical lens from water surface, centre, the bottom respectively, and whether statistics air bladder is inflated.In view of contract in early stage limit, omit test herein and use fish species name, be referred to as prelarva, relate to specified place and time with " xxx " replacement.In addition, because between kind, ontogeny differs greatly, narcotic consumption, anesthesia duration should specifically be considered.Only give output detection method herein, for the concrete consumption of specific kind, scope on probation carrys out concrete operations depending on its developmental stage Individual Size.
Test temperature: 24.8 DEG C;
Natural seawater salinity: 38 ‰;
PH：7.1
Data 1:
Fry is used in test: a kind of fish prelarva;
Age: latter 8th day of hatching;
Anaesthetic consumption: anaesthetic reaches 12mg/L metering in cylinder;
Anesthesia duration: 5-8 minute, the time is more short better;
Sampling after anesthesia: keep afloat, air bladder 100% is inflated; Float in water, air bladder partial inflation; Sink to the bottom: 85.9% air bladder unaerated;
Data 2
Fry is used in test: a kind of fish prelarva;
Age: latter 12nd day of hatching;
Anaesthetic consumption: anaesthetic reaches 12mg/L metering in cylinder;
Anesthesia duration: 5-8 minute, the time is more short better;
Sampling after anesthesia: keep afloat, air bladder 100% is inflated; Float in water, air bladder partial inflation; Sink to the bottom, 80.1% air bladder unaerated.
The above; be only the present invention's preferably embodiment; protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses, the simple change of the technical scheme that can obtain apparently or equivalence are replaced and are all fallen within the scope of protection of the present invention.
Claims (1)
1. judge the method whether seawater fry air bladder is inflated fast, it is characterized in that, at fry hatching membrane 10-25 days, the anaesthetic of employing is Aqui-S, measures as 12-18mg/L; Density measurement is 100 ml water 100 tail fries, and anesthesia duration is 5 minutes, and when fry is in the state that can not initiatively swim, on bubbling through the water column, then air bladder is inflated completely, if in water, air bladder partial inflation, is sunken to the bottom then air bladder unaerated;
Anaesthetic add nursery cylinder before should with seawater premix, then add nursery cylinder;
Inflation is noted in nursery cylinder.
