摘要：
The effect of 18 mg. melatonin (MLT) implants on the reproductive performance of turbot (Scophthalmus maximus L.) broodstock was determined in 20 females and 12 males. Implanted animals showed supra-physiological plasma MLT concentrations during three months after implantation, being at that time about one hundred times higher than diurnal MLT concentrations. Direct effects of MLT implants were observed on gonadal maturation of turbot females three months after implantation (P < 0.01), although the faster ovarian response to increasing photoperiod was not consistent and no differences were detected at the final reproductive performance. MLT implants had a positive effect on turbot male reproductive features, since gonadal recrudescence started 45 days earlier (P < 0.05) showing a trend towards higher spermatozoa concentration. Further research is advisable to ascertain the MLT dose required for and time of implantation in turbot broodstock.
