Method for rapidly determining inflation of seawater fry swimming bladders

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 sta...

Zusammenfassung:	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.
