Abstract
    The Catfish, Pimelodus blochii, is a seasonal breeder distributed in rivers of the Venezuelan plains. Under natural conditions, it has an annual gonadal cycle closely related to seasonal changes during the dry and rainy season. The purpose of this study was to evaluate the changes in the content of total lipids (TL) and fatty acids (FA) in gonads of female and male P. blochii, during gonadal maturation. Adult P. blochii (Teleostei, Siluriformes) were collected on a regular basis from February to July 1998 from Cano Igueez, Portuguesa State in Venezuelan plains. Total lipids were analysed gravimetrically and the composition of fatty acids was determined by gas-liquid chromatography. Lipid concentrations are indicated as mg/g tissue. Comparisons between groups were analysed with unpaired Student's t-test. Significance was accepted at the 0.05 level.
