This survey represents the first dedicated exploratory research survey for boarfish (Capros aper) undertaken along the western seaboard. The commercial fishing vessel the MFV Felucca, an active participant in the fishery was equipped with a calibrated scientific echosounder. A consultant biologist from the Killybegs Fisherman’s Organisation (KFO) and a Marine Institute scientist headed the biological and acoustic research respectively during the cruise. Exploratory fishing for boarfish by Irish vessels began in the later 1980s when commercial quantities were encountered during the spring horse mackerel (Trachurus trachurus) and mackerel (Scrombrus scomber) fishery in northern Biscay. Several landings were made into Ireland for fishmeal during this time but due to logistical problems related to handling (prominent dorsal spines) this species was not favoured by processors. Interest increased again around the mid 1990s when Dutch pelagic vessels landed frozen samples to determine if a market could be developed for human consumption. From the early 1970s onwards the abundance of boarfish was seen to increase exponentially and distribution ever increasingly spread northwards along the western seaboard (Blanchard and Vandermeirsch, 2005). With this increase in abundance boarfish were taken as bycatch in both the pelagic and demersal fisheries in ever increasing quantities and this caused serious problems relating to damaged target species due to the aforementioned formidable dorsal spines. During the early 2000s the Irish landings were relatively small ( |
