dc.description.abstractThe growth of freshwater clam Galatea paradoxa (Born) from the Cross River, Nigeria, was studied based on a count of growth checks on shells, presumed to be laid down annually. Mean lengths at ages 1 to 5 were 4.1 cm, 5.9 cm, 7.4 cm, 8.4 cm and 9.0 cm, respectively; maximum observed size was 11.1 cm. Growth conformed to the von Bertallanffy growth model with the parameters L sub( infinity ) = 11.2 cm, K = 0.3 year super(-1) and t sub(0)=0.5 year super(-1). Total and natural mortalities were estimated at 0.8 and 0.3 year super(-1), respectively; the statusof the fishery is briefly discussed.
