The reproduction season affects the organism physiology producing a great of deal of tissue which affect the energy requirement; so, the gonadal development influences on the oxygen uptake. Therefore, the propose of this work is the determination of the relationship between the gonadal development and the oxygen consumption in the raplike clamp Protothaca asperrima. So, a study was carried out from January 1995 to January 1996 at the Bique beach, Arraijan. This work consisted in the determination of the oxygen consumption by Winkler method and the gonadal development by histology. Our results reveal a higher oxygen uptake in April, decreasing from this up to October where it increases again. There was not correlation between oxygen consumption and physical factors. There was not relationship with the ovocite length nor with gonadal stage. Therefore, apparently there is not relationship between oxygen uptake and gonadal development in this specie.
