(...) During April 1997 the acoustic detector was successfully used to detect vaquitas for the first time. On that occasion we surveyed on a fixed location, aboard an outboard motor…
Trends in abundance of the Gulf of Maine population of harbour porpoise
Olson, P. A.
Master's Thesis - University of Rhode Island (1996)
Hundreds of harbor porpoise die each year as bycatch in the Gulf of Maine's sink gillnet fishery. In recent years, concern has arisen whether the Gulf of Maine population of…
Potential rates of increase of a harbour porpoise (Phocoena phocoena) population subjected to incidental mortality in commercial fisheries
Woodley, Thomas H.; Read, Andrew J.
Canadian Journal of Fisheries and Aquatic Sciences (1991)
We estimated the potential intrinsic rate of increase (r) of the harbour porpoise (Phocoena phocoena) population in the Bay of Fundy and Gulf of Maine using empirical data on reproductive…
Change in occurrence of the harbour porpoise, Phocoena phocoena, in Danish waters as illustrated by catch statistics from 1834 to 1970
Andersen, S. H.
FAO Fisheries Series (1982)
During 24 seasons (November, December and January) from 1834 to 1892, 27 992 harbour porpoises, Phocoena phocoena, were taken in the Strait of Lille Baelt, Denmark with a mean annual…
Current understanding of the status of small cetacean populations in the Black Sea
Smith, T. D.

Spatial and temporal distribution of harbour porpoises in relation to their prey
Sveegaard, S.
Doctoral Thesis - Aarhus Universitet (2011)
The population status of harbour porpoises has been of concern for several years due to anthropogenic influences, especially incidental bycatch in gillnet fisheries. Proper management of a wide-ranging species such…
