Nursery habitats play a major role in the population dynamics of marine and estuarine species, with the blue crab Callinectes sapidus serving as a model invertebrate. The current paradigm of blue crab habitat use postulates that juvenile survival decreases with size in submerged aquatic vegetation (SAV) due to a reduction in suitably scaled refuge, triggering an ontogenetic shift from SAV to unvegetated habitats. However, alternative mechanisms for this habitat shift have not been examined. We evaluated the paradigm of blue crab habitat use by conducting field tethering experiments in York River (Virginia, USA) nursery habitats using a broad range of …

Seed size at planting is the dominant factor affecting hard clam survival to marketable size when field grow-out techniques are used. The use of plastic mesh nets, crab traps, and wire mesh bags (filled with oyster shells) alone or in combination can be used to increase survival of hard clams of ~ 6 to 8-mm shell height. These techniques do not provide sufficient protection for 2-mm seed. The combination of net + crab trap + shell bag was nearly twice as effective as the net alone when 10 to 14-mm seed was used and over five times as effective as …
