| From November 1978 to January 1982, the author has studied the effects of Amoco Cadiz oil spill on plaice (Pleuronectes platessa) reproduction, main species of flat fish of the aber Wrac'h and aber Benoit. Serious alterations of the function were observed in females. Examining the gonado-somatic ratio has revealed some anomalies in the reproductive process. Study of ovary histology has shown large cytologic modifications. Some hypothesis have been retained: oil action in situ, use of lipidic reserves for another aim than reproduction, and hormonal perturbations. |
