Preliminary estimation of total mortality for shrimp (P. Borealis) in the Anticosti Channel / by J. Fréchette and D.G. Parsons.: Fs70-8/81-82E-PDF

"Data from surveys made by the Direction génera1e des pêches maritimes, Quebec in 1978 and Research and Resource Services, Newfoundland in 1978-1980 were analysed to estimate year-class strength and mortality for the shrimp stock of the Anticosti Channel. The estimates of biomass for these years were broken down by age class using modal separation of length frequency distributions. For fully recruited age groups (females) total mortality was estimated at 0.62 between 1978 and 1979 and 0.91 between 1979 and 1980. Results indicated that a dominant year-class (possibly 1978) was present. The relative strength of this particular age group should improve the 1981 catch rate in this area as these animals become fully recruited."--Abstract.
