Book Description
"Background information is presented on the development of a directed fishery for jonah crab, Cancer borealis, on the Scotian Shelf during 1983. Before the fishery closed due to processing problems, 90.3 metric tons (MT) of jonah crab were landed by 10 permit holders through the period May-August. Port and at-sea sampling of commercial catches indicate that the mean size for landed males remained relatively constant and well above the minimum size limit of 130 mm carapace width "--Abstract, page 2.

Book Description
This report presents some basic biological information on the Jonah crab (Cancer borealis). It describes the crab fishery (landings, and catch and effort) on the Scotian Shelf, and uses commercial data to describe the status of the resource. It also discusses certain management considerations and provides an outlook for the stock.

Book Description
This report presents an assessment of the Scotian Shelf Jonah crab fishery based on sea samples, port samples and analysis of mandatory fisher logbooks. It provides information on catch per unit effort, effort, and landings, and discusses the results of experiments on entrance restrictions, handling mortality, packing density, bait bags, bait type and trap designs. Also discusses issues related to management of the fishery.

Book Description
A workshop was held to explore the need for an ecological research and monitoring site in the Atlantic Maritime Ecozone, with particular reference to the land/sea/atmospheric interface (coastal zone), and to explore the suitability of the Huntsman Marine Science Centre, in conjunction with the Fisheries and Oceans Canada Biological Station, as the administrative center of such a site. This publication presents summaries of the working group discussions on estuarine and marine ecosystems, terrestrial and aquatic ecosystems, and ecosystems data management, and includes papers presented at the workshop. The topics of the papers include ecosystem and wildlife monitoring, atmospheric variables and trees, research and monitoring programs, sulfur dioxide deposition, lakewater chemistry, benthic monitoring, and nutrient cycling patterns.

Book Description
This bulletin reviews the Jonah crab fishery in the Gulf of Maine off the south-west coast of Nova Scotia and the status of the crab resource as determined from fishery surveys, including information on landings, crab size distribution, & lobster by-catch. The final sections review uncertainties in the data, provide an outlook for the Jonah crab stock, and discuss management considerations.
