Extract

Nine hundred and fifty-four bass were tagged, mainly by anglers, in the river estuaries and off the coasts of Cornwall, Devonshire, Dorset and Hampshire, England, in 1970 and 1971. To date 59 bass have been recaptured, 86 % by anglers, 12 % by commercial fishermen and 2 % by research vessels. Forty-seven bass were recaptured within 16 km of their release point. Of the 12 bass recaptured at a greater distance, four were taken within 90 days and had moved by an average of 1.4 km/day. From the tag returns and the length distributions of the bass tagged by areas it is concluded that bass form permanent populations in estuaries until they are 2–3 years old, when they move offshore, eventually becoming very mobile as evidenced by the long-distance movements observed.
