Growth rates were determined for scallops (35-75 mm valve height) held in pocket nets and lantern nets at varying densities. The Ford-Walford linear transformation of the von Bertalanffy growth equation was used to allow quantification of food-limited stunting. Pocket nets allowed for greater growth of scallops than did the lantern nets at all stocking densities. The growth rates of scallops in pocket nets, nevertheless, were well below the growth of scallops in the wild. Clearance rates of Caribbean strains of Isochrysis galbana (C-ISO) and Chaetocerous gracilus (C-Cg) were determined for moon scallops. Amusin pleuronectes, in static chambers at 28ºC. The …

In contrast to most artificial reefs which are placed at relatively deep depths so as not to interfere with shipping, rocky breakwaters provide important habitat in the intertidal-shallow subtidal zone. This zone is especially preferred for recruitment by many rocky shore fishes. The breakwaters of King Harbor, Redondo Beach, California enhance this zone. Further, the lee of the outer breakwater provides a stable, quiet water area for numerous Young-of-Year (YOY) fishes. By means of SCUBA we monitored YOY abundance from 1986-1990. During these five years there were dramatic natural and anthropogenic disturbances of the habitat. With little inter-annual variation of …

In January 1993, The Waterworks Group initiated the Bay Scallop Restoration Project as an attempt to restore the once prolific bay scallop within the Westport River Estuary in Massachusetts. This project is a multi-phased endeavor aimed at better understanding recruitment failures of both natural stocks and introduced seed of Argopecten irradians. The main objective of this project is to assesss juvenile recruitment (survival to > 4mm) to artificial spat collectors placed in historically productive scallop beds and within close proximity to adult spawner rafts. Spat collectors (2 to 4mm plastic mesh bags) containing monofilament were suspended on 28 to 35-meter floating …
