Skates/Rays

Displaying 1 - 10 of 17

Study Type: 

Field study in the wild

Location: 

Minch and Stanton Banks

Target catch: 

Whitefish

Effect on bycatch species: 

Removing the 'tickler' chain resulted in decreased catches of sharks and skates

Effect on target catch: 

Catch rates for flatfish, haddock and whiting did not differ. Larger anglerfish were caught without the 'tickler' in place

Data from the Northwest Atlantic suggests that the thorny skate began declining in the early 1980s and accelerated in the early 1990s (Burgess et al 2005). In US waters, dredging for scallops also poses a risk (Packer et al 2003). Additionally, a targeted fishery for the species emerged in Canada in order to meet a growing European demand for skate wings (Kulka et al 2009). Bycatch in Canadian waters occurs on the Scotian Shelf, though landings do not equal those of the targeted fishery (Kulka et al 2009).
