Final maturation and ovulation provoked by supply of homologous hypophysis in Hoplias m. malabaricus (Pisces, Erythrinidae).
The final maturation and the ovulation were induced in recently collected specimenes of Hoplias m. malabaricus that show oocytes with complete vitellogenesis, by using homologous hypophysis. The hormonal supply was a gradual and positive results were obtained with 9 to 10 hypophysis/kg injected according to 3 different methods. The time of oocytes' maturation from the first dose ranges between 32 and 60 hours a 18 degrees C. The stages of maturation of the oocyte were controlled by intraovaric cannulations using a numerical index to determine the position of the germinal vesicle.
