Cooperative Research Pilot Flatfish Survey (Yellowtail)

Description

An industry-based pilot flatfish survey of Georges Bank conducted aboard the F/V Mary K and the F/V Yankee Pride. The surveyed used a two-seam, two-bridle flounder net which utilized a sweep consisting of 4” rubber cookies, 20 fathom bridles, and 5 fathom extensions. Both vessels used 734 kg Thyboron type IV 84” trawl doors and utilized a 23 fathom restrictor wire between the doors to ensure consistency in door spread. The U.S. portion of Georges Bank was divided into “high density” and “low density” strata based on input from fisherman and previously collected survey and observer data for yellowtail flounder. Stations were randomly selected within each stratum, with higher sampling intensity in the high density stratums. Tows were conducted for 20 minutes at a target speed of 2.8 knots. At locations where the seafloor would not allow a tow to be completed with the chosen gear, the nearest towable area was selected by the captain as an alternate.1
