Stereological studies on the gametogenic cycle of the scallop, Pecten maximus, in suspended culture in Ria de Arousa (Galicia, NW Spain)

Samples of Pecten maximus cultured using the ear-hanging technique were collected at regular intervals from April 1990 to July 1991. The gametogenic cycle has been studied in relation to the environmental conditions (temperature, chlorophyll a and seston) and assessed by two different methods: determination of the gonad condition index and study of the oocyte diameter by image analysis following a Stereological technique. Two principal spawning...
