INDUKSI KEMATANGAN GONAD INDUK JANTAN KERANG ABALONE (Haliotis asinina) DENGAN METODE LASERPUNKTUR

Abalone  is  one  kind  of  shellfish  fisheries  of  the  world  has  become  a  commodity  which  is currently experiencing  increased demand, especially  from  international markets. As one  initial step of a series  of  required  maintenance  management  process  of  cultivating  a  good  broodstock,  to  get  the broodstock with  the maximum  level of gonad maturity  is by  induction using  laserpunctur. Laserpunctur appropriate technology has been shown to accelerate the growth process, increase and accelerate gonadal maturation and spawning shorten  the reproductive cycle of some species. The purpose of  this study was to  determine  the  effect  laserpunctur  fired  on  gonadal  organs  of  the male  gonadal maturity  of  abalone shells and the best energy of the male gonadal maturation affect abalone shells.  The  treatment  used  is  laserpunctur  irradiation  on  the male  gonad  organ  abalone  shells with  a energy of 0 Joule (control), 0.5 Joules for 50 seconds, 1 Joule for 100 seconds, 1.5 Joules for 150 seconds and 2  Joule  for 200 seconds. Each  treatment was  repeated  four  times. The  results of  this  study was  the laserpunctur  irradiation  fired  on  the  gonadal  organs  influence  the  development  of  gonadal maturity  of male broodstock abalone shells. The best energy of laserpunctur in the male gonad maturation affects the abalone  shells  is  1.5  Joules  for  150  seconds.  The  results  of  histological  observation  of  gonadal male broodstock H. asinina showed varying degrees of gonadal development  in  the process of gametogenesis is marked with an individual s reproductive cycle.
