Profile of Catfish (Clarias sp) Oocyte Exposed by Laserpuncture

Abstract

Anexposure of low-powered laserpuncture at reproductive acupoint of catfish brood stock is known stimulate oocyte maturation. However, the profile of oocyte resulted from laserpuncture exposure has not been known. The present study aimed to identify the profile of catfish (Clarias sp.) oocyte in post-exposure laserpuncture. A total of 48 catfishes with ages of 8-9 months was grouped into two, i.e. fishes were exposed with laserpuncture and without exposure to laserpuncture (control) with 3 replications. Laserpuncture exposure was conducted once a week until the brood stock matured. Profile of oocyte such as, the GSI value, egg diameter, total of oocytes and the gonad maturity stage were examined. The results showed that laserpuncture exposure at the catfish reproductive acupoint could trigger the oocyte development without reducing quality of the oocyte indicated by the increase of gonadosomatic index (GSI), oocyte diameter, total of oocytes and gonad maturity stage similar to control. Moreover, laserpuncture exposure accelerated the gonad maturation, three weeks faster than control.
