Abstract Broodstock of the venerid clam Katelysia rhytiphora (Lamy) and of the Sydney cockle Anadara trapezia (Deshayes) were induced to spawn using temperature fluctuations. Larval cultures of K. rhytiphora contained D veligers (97.1±3.7 μm shell width) within 48h, umbonate larvae by day four and pediveligers by day 11. On day 12, pediveligers (198.3±5.39 μm shell width) were placed on settlement screens and allowed to metamorphose over the following 9 days. Larvae of A. trapezia developed to… CONTINUE READING
