Hormonal Induction of Maturation in Striped Mullet, Mugel cephalus
Abstract:
The effectiveness of chronic release hormone implants for stimulating testicular and ovarian maturation in striped mullet, Mugil cephalus, was examined. Ten milligram 17α-methyltestosterone silastic capsules induced a significant increase in milt production in males for up to 11 months. Two hundred microgram luteinizing hormone releasing hormone analog pellets accelerated vitellogenesis, which led to an increase in the number of females that developed an additional clutch of oocytes during the spawning season. Hormone implants therefore provide a means for mullet hatcheries to increase broodstock performance.
