Extract

An analysis of the quantity and distribution of unspawned eggs in the gonad of o. edulis recorded in Table IV, 1, 1927 (of oysters with young) and Table IX, 1,1927 (of post-spawned oysters), gives useful information regarding the occurrence and fate of unspawned ova as may be seen from the figures given in Table A.
