Estimation of natural and total mortality rates of Northwest Atlantic mackerel / by G.H. Winters. : Fs70-8/78-35E-PDF

"The assessment of abundance and optimal yield levels of Northwest Atlantic mackerel (Scomber scombrus ) has generally been complicated by divergent conclusions as to the appropriate level of natural and fishing mortality rates. The level of natural mortality (M) currently being used in cohort analyses (M = 0.30) was arrived at more by compromise consensus than from data analyses. In addition estimates of terminal fishing mortality in 1976, for example range from 0.48 to 0.85. Although extensive data have been made available from commercial and research sampling activities during the past decade, these have not been analyzed with regard to definitive evaluation of the natural mortality rate of mackerel. Such analysis form the basis of this report"--Introduction.
