An update of the inshore code stock in Subdivision 4Vn (May-Dec) for 1980 / by S.J. Smith and B.A. Charlton. : Fs70-8/81-20E-PDF
"The status of the 4Vn (May-Dec) cod fishery for 1980 is studied here by considering the apparent trends in the stock size indices available (e.g. commercial CPUE and research survey estimates). Previous studies on this stock have determined that this fishery is supported by three stock complexes - 4T cod stock, 4Vs cod stock and the 4Vn 'inshore' stock. The major proportion of the catch is assumed to be taken from the inshore stock. Recent changes in the behaviour of the major inshore gear, the longliners, from fishing inshore areas to the present situation of fishing out to the Laurentian Channel suggests that the offshore stocks of 4T and 4Vs are now contributing proportionally more to the fishery. The 1980 reported catch of 10,378 mt (a nine year high) seems therefore to be a result of increased effort toward the offshore components rather than an increase in population size of the inshore component."--Abstract.
