Estimation of exploitation and migration rates of Atlantic cod (Gadus morhua) in NAFO subdiv. 3Psc and divs. 3KL during 1997 and 1998 based on tagging experiments / by Noel Cadigan and John Brattey.: Fs70-1/1999-38E-PDF
In this paper a simple cyclical-seasonal migration model is used to estimate migration rates of cod between Placentia Bay off the south coast of Newfoundland (3Psc), and the inshore off the northeast coast of Newfoundland (3KL). The model is also used to estimate exploitation rates for the 1997 and 1998 fisheries in those regions. The results indicate that the exploitation of cod in Placentia Bay was 7% during January-June 1997, and 4% in the remainder of the year. Exploitation was also very low during the first half of 1998 in Placentia Bay, but increased to 10% in the second half of the year. Exploitation in 3KL was very low in 1997 and the first half of 1998 due to lack of fishing activity, but in the second half of 1998 exploitation was estimated to be 6% for cod in northern 3L and 3K, and 12% for cod in southern 3L.
