摘要：

Fry from six egg batches of Oreochromis aureus were reared at 21 degrees C (40 days), 27 degrees C and 34 degrees C (25 days) then at 27 degrees C and sexed. High temperature regimes produced high male ratios (mean male percentage: 97.8%) while intermediate thermal regime gave balanced ratios (mean male percentage: 63.0%). Low temperature delayed the differentiation of gonads. Perspectives of using high temperature for the production of monosex populations are discussed. (C) 1998 Elsevier Science B.V.
