Although development fishery region could bring economic benefits, may be hampered by presence disease syndrome known as black gill (sBG). The objectives our study were to (1) describe spatial distribution and abundance patterns Bay, (2) relate...
BACKGROUND The Firth of Clyde is a large inlet of the sea that extends over 100 km into Scotland's west coast. METHODS We compiled detailed fisheries landings data for this area and combined them with historical accounts to build a picture of change due to fishing activity over the last 200 years.

A bioeconomic model was built to assess the contribution of more selective trawl nets objectives European Multi-Annual Plan for demersal fisheries in Western Mediterranean (WM MAP). The biological submodel parameterized with age-structured population parameters five target stocks WM MAP (European hake, red mullet, deep-water rose shrimp, Nephrops and shrimp) a sixth stock combining remaining co...
Many species of interest to management and conservation remain data-limited, the data that are available often unable produce statistically reliable population trends. We examined 10 years juvenile reef fish catch from two gear-specific, fishery-independent surveys in eastern Gulf Mexico assess our ability 1) characterize trends for various sampled using haul seines or otter trawls 2) amend sur...
Discards represent a loss of natural resources and negatively affect the sustainability fisheries. Information on discards, such as diversity size species discarded is essential to better manage trawl Thus, this study aims gain knowledge discards from Catalan bottom fisheries in NW Mediterranean Sea offer information needed for management. Discard ratios, composition lengths were analyzed data ...
