INDICATIVE ESTIMATES OF BIOMASS AND YIELD OF WHITSON’S GRENADIER (M. WHITSONI) ON THE CONTINENTAL SLOPE OF THE ROSS SEA IN SUBAREAS 88.1 AND 88.2
bootstrap procedure. Indicative estimates of M. whitsoni biomass for the Ross Sea slope ranged from 26 892 t ... (cv = 29%) to 41 823 t (cv = 28%) depending on assumptions. Applying estimates of gamma (γ) =0.01439 ... and 0.01814 gave indicative estimates of yield in range 386–602 t and 487–759 t respectively. These ... indicative yield estimates provide tentative support for the bycatch limit of 374 t currently in place for M ...
