| Popis: | Recoveries of tags have provided limited information on the dispersion of several British Columbia groundfishes. Platichthys stellatus and Hippoglossoides elassodon were recovered mostly within 1 to 3 years and have moved less than 5 miles; however, one P. stellatus shifted position by 60 miles in 51/2 years. A very few recoveries of Psettichthys melanostictus tags suggest that movements up to 25 miles may be not uncommon for this species. Anoplopoma fimbria recoveries 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 male P. stellatus varies from 35 mm. at 350 mm. initial size to 10 mm. at 520 mm. |
