. The effect of two GnRH‐As – des Gly 10 (D‐Ala) 6 LHRH and des Gly 10 (D‐Tle) 6 GnRH in total doses 10–249mu;g/kg – and four neuroleptics – pimozide, sulpiride, metoclopramide and isofloxythepin in total doses 1–50mg/kg ‐ and environmental temperatures on the development of final stages of Pacific mullet oogenesis was investigated. The best technique of those used by us for spawning stimulation of Pacific mullet, Mugil so‐iuy Bas., females is shown to be administration of neuroleptics in doses of l‐8mg/kg with posterior injections on GnRH‐A in doses of 25 and 50mu; g/kg applied 4 and 28h respectively after the neuroleptic injection. At water temperatures below 17°C, ovulation does not occur unless the optimal stimulation is applied.
