The Effect Of Crude Extract Green Mussel (Perna viridis) With Intramuscular Injection In Promoting Pangas Catfish (Pangasius hypothalamus) Gonadal Maturation

Abstract

The management of broodstock is a crucial step in the fish breeding process. The size of the body and
gonadal maturity are significant aspects of broodstock quality in aquaculture. To produce high-quality fish, the
brood needs to possess fully grown gonads and an ideal body size. According to several studies, green mussel
extract is thought to stimulate zebrafish growth and gonad maturation caused by estradiol compounds, although
further testing on other fish, such as the Pangasius hypothalamus, has not yet been done. This research aims to
evaluate the effect of administering crude green mussel extract containing estradiol compound via intramuscular
injection on the growth and maturation of pangas catfish gonads. The pangas catfish broodstock was treated with an
injection of green mussel extract and ovaprim at a dose of 0.5 mg/broodstock with three repetitions over a 30-day
maintenance period. The results show that the administration of green mussel extract at a dose of 0.5 mL/kg
increases weight growth. The homogeneity level of eggs in female pangas catfish induced with green mussel
extract is the same diameter as induction with ovaprim and slightly different from the control specimen (without
treatment). The results show that the crude extract of green mussels in the methanol fraction, at a dose of 0.5
mL/kg, can increase growth and egg diameter.
