摘要:

Recoveries of tags have provided limited information on the dispersion of several British Columbia groundfishes.Platichthys stellatusandHippoglossoides elassodonwere recovered mostly within 1 to 3 years and have moved less than 5 miles; however, oneP.stellatusshifted position by 60 miles in 51/2 years. A very few recoveries ofPsettichthys melanostictustags suggest that movements up to 25 miles may be not uncommon for this species.Anoplopoma fimbriarecoveries were nearly all within 10 miles of release but tagging was done under conditions favouring local recovery. During a year's freedom the average growth of a maleP.stellatusvaries from 35 mm. at 350 mm. initial size to 10 mm. at 520 mm.
