Mackerel migrate to Newfoundland waters from July to November and exhibit periodic fluctuations in abundance. Recent taggings have shown extensive migrations from Newfoundland to ICNAF Statistical Area 6. Various biological characteristics of mackerel from Newfoundland waters are reported and compared with those for mackerel caught in the New England area. A consideration of tagging results, biological characteristics, and ecological factors indicates that for assessment purposes mackerel inhabiting ICNAF Subareas 3–6 should be treated as one stock rather than assessed separately as northern and southern contingents each with a separate quota.
