Off the east coast of Canada we observe some marine ecosystems that are still recovering from prior overexploitation, such as the Newfoundland sh elf, while other regions have witnessed recent expansion of fishing industries, such as the waters off of Nunavut. This project seeks to analyze trends in overall ecosystem health and to assess the overall impacts fishing acti vit ies have on fish and invertebrate communities from the southern Grand Banks to northern Nunavut using a technique called size spectra modeling.
Fisheries are a fundamental contributor to socio-economic growth in northern Canadian communities and are a management priority considering limited alternative economic opportunities available in the region. The proposed research aligns with core research needs of industry/resource managers to meet three objectives: 1.
Porcupine Crab (Neolithodes grimaldii) inhabits the seabed off the Coast of Newfoundland and Labrador and in the eastern Arctic as a by-catch in the turbot gillnet fishery. This research project focuses on developing automatic robotic technology for the removal of Porcupine Crab spines to ease the crab processing for potential future development of a Porcupine Crab fishery.
Porcupine Crab (Neolithodes grimaldii) is harvested off the coast of Newfoundland and Labrador and in the eastern Arctic as a by-catch in deep water during the turbot fishery. Its dark red color and long sharp spines make handling and processing very difficult. Preliminary experiments have shown that quality crab meat products can be produced from porcupine crab however no commercial fishery, processing procedures or markets, have been established.
