Ringed Seals in James Bay and Hudson Bay: Population Estimates and Catch Statistics
ABSTRACT. The populations of ringed seals Phoca hispida in Hudson Bay and James Bay are estimated on the basis of aerial counts to be 455,000 and 61,000 respectively. If the maximum number of seals, estimated at 21,000, needed to feed the polar bears of Hudson Bay is added to the catch of all tradin...

| Summary: | ABSTRACT. The populations of ringed seals Phoca hispida in Hudson Bay and James Bay are estimated on the basis of aerial counts to be 455,000 and 61,000 respectively. If the maximum number of seals, estimated at 21,000, needed to feed the polar bears of Hudson Bay is added to the catch of all trading centres there, estimated at 14,900, the total approximates very closely to the 8 per cent annual sustainable yield of ringed seals in Hudson Bay. R6SUM6: Population estimée et statistiques des prises de Phoque annelé dans la baie de James et dans la mer d'Hudson. A partir de comptages akriens, l'on estime les populations de Phoque annelé (Phoca hispida) dans la baie de James et dans la mer d'Hudson A 455 000 qt 61 000 têtes respectivement. Si l'on additionne le nombre maximiun de phoques nécessaires A l'alimentation des ours polaires, nombre estime A 21 000, et la prise totale de tous les centres de traite, estimk A 14 9 0 0 , le total Bgale de tri% prks le 8 % de phoques anneles disponibles chaque ann& pour la r h l t e dans la mer d'Hudson. |
