From the Gulf of Maine/Bay of Fundy harbour porpoise Phocoena phocoena population, the average abundance was 47 200 for 1991 and 1992. Based on observer programs, in 1993 the bycatch in the groundfish sink gillnet fishery from the US Gulf of Maine was 1400 and 200 to 400 animals from the Canadian Bay of Fundy. From the Gulf of St. Lawrence, no abundance estimates are available, and based on mail surveys conducted in 1989 to 1991, approximately 2800 harbour porpoises were caught annually in fishing gear. Reliable abundance and bycatch estimates are not available from the Newfoundland population. Information on life history and reproduction parameters, diet and contaminant concentrations are also provided.
