| Summary: | Analyzes the relationships between the standard length, max girth, axillary girth and blubber thickness of 73 ringed seals, 71 of them taken at Sachs Harbour, Aug-Sept 1966. Data for the 61 seals from SW Baffin Island first studied by MacLaren, No 53026, are reanalyzed to determine which relationships give the most reliable prediction of weight. A formula using length and max girth as factors is the most precise, and the best single indicator is girth. Tables showing the relationship between weight, length and girth, as derived from two of the six formulas presented are given supra. Rapports entre le poids, la longueur et la circonférence du phoque annelé (Pusa hispida) de l'Arctique canadien. On analyse les rapports entre plusieurs mesures du corps chez le phoque annelé, de façon à déterminer lesquelles de ces mesures permettent de déduire le poids de l'animal. La formule qui relie les deux paramètres longueur et circonférence maximale est la plus précise, alors que la circonférence est le meilleur indice isolé.
