Major features of the distribution and life history of some commercially fished benthic invertebrates in the Sydney Bight area
By Tremblay, M.J., A. Reeves, T. Worcester
Abstract
The distribution and life history of some invertebrate resource species within Sydney Bight is reviewed. Available data come from commercial landings, research trawl surveys and special projects. These data are not extensive but provide an outline of the distribution of species such as lobster (Homarus americanus), rock crab (Cancer irroratus) toad crab (Hyas araneus and Hyas coarctatus), northern stone crab (Lithodes maja), northern shrimp (Pandalus borealis), sea urchins (Strongylocentrotus droebachiensis), and sea scallops (Placopecten magellanicus). The important snow crab (Chionoecetes opilio) resource is covered in another paper. For most of the aforementioned species, important questions remain regarding seasonal distribution, size structure, and the timing of life history events.
