Data from 65 studies, 25, 20 and 20 for CPE, LHRHa injections, and LHRHa implants, respectively, were evaluated. Mean fry/kg female body weight (all females) produced was 948, 2483 and 2765 for CPE, LHRHa injections, and LHRHa implants, respectively. LHRHa administered as an injection or implant produced more (Pb0.001)fry/kg than CPE. LHRHa implants and CPE (CV=37.5) gave a more consistent result (CV=35.9) than LHRHA injections (CV=49.9). LHRHa is advantageous for ovulating channel catfish for producing hybrid catfish fry compared to CPE. This advantage is even more important if brood fish, space or time are limiting
