Movements of tagged summer flounder, Paralichthys dentatus, off southern New England

A total of 2,839 summer flounder were tagged on outer continental shelf and coastal grounds off southern New England in 1961-62. Tag recaptures showed the migration to offshore grounds in fall and winter and to inshore areas in spring and summer. Recaptures from coastal grounds were recorded from northern New Jerse) to south of Cape Cod; those from outer shelf grounds were from Baltimore Canyon on the southwest to Veatch Canyon on the northeast. The overall tag return rate was 21.2"70 ; however, the returns from inshore tagging (44.5"70) were much higher than those from offshore releases (8.4"70), suggesting that tagging mortality was higher offshore.
