| 520 | 3 |a"Stratification by depth zone and by individual strata were compared as to their effect on cod abundance estimates from research surveys in NAFO Subdiv. 3Ps. Stratification by depth zone was proposed as a means of providing population estimates for surveys where coverage was incomplete and when catches were highly variable. Combining strata within depth zones effectively increased the number of sets in the new strata and generally reduced the variances associated with the abundance estimates. Estimates of mean numbers per tow from both methods followed similar patterns."--Abstract |
