attribute NC_GLOBAL acquisition_description String The Northeast Fisheries Science Center (NEFSC) has conducted bottom trawl\nsurveys for juvenile and adult fish on the NEUS Shelf over the past four\ndecades (Azarovitz 1981). The surveys were conducted in the spring (March-\nApril) and fall (September-October) using a stratified random design. All fish\nfor each species were counted and weighed. Literature values of the estimated\nmedian size at maturity (50th percentile) were used for most species to\ndetermine size at maturity and only mature adults were included the catch\nestimates.\n \nReferences:  \n Azarovitz TR. 1981.

attribute NC_GLOBAL instruments_0_dataset_instrument_nid String 560560
attribute NC_GLOBAL instruments_0_description String Otter trawls have large rectangular otter boards  which are used to keep the mouth of the trawl net open. Otter boards  are made of timber or steel and are positioned in such a way that the  hydrodynamic forces, acting on them when the net is towed along the  seabed, pushes them outwards and prevents the mouth of the net from  closing. The speed  that the trawl is towed at depends on the swimming speed of the species  which is being targeted and the exact gear that is being used, but for  most demersal species, a speed of around 4 knots (7 km/h) is appropriate.
