Biotic relationships of Illex coindetii and Todaropsis eblanae (Cephalopoda, Ommastrphidae) in the Northeast Atlantic: Evidence from parasites
Parasites were collected from 1,200 short-finned squid (Illex coindetii, Todaropsis eblanae) caught as by-catch in a multispecies trawling fishery in the northwest Spanish Atlantic waters in 1992-1993. Parasites found included six species of helmiths, three tetraphyllidean cestodes (Phyllobothrium s...
