Impacts of predation by seals and dogfish on fish caught in gillnets has been largely neglected. This is important in Cape Cod’s Fixed Gear Sector because all discarding associated with predation is counted against the sector’s Total Allowable Catch (TAC). This results in a loss of profits for fishermen within the sector. Between June 3rd and July 3rd 2007, sixty-one gillnet hauls were observed during regular commercial fishing activities in order to investigate predation rates of both species. Allometric regression was used in tandem with weight conversion factors to determine the estimated total weight of eaten and discarded fish in each haul. Spatial relationships and predation rates relative to certain environmental variables were also ...
