	Harbour Porpoise - Wikipedia, the free encyclopedia
		The Harbour Porpoise, as its name implies, stays close to coastal areas or river estuaries and as such is the most familar porpoise to whale watchers.
		Harbour Porpoises are not and never have been actively hunted by whalers because they are too small to be of interest—an adult is about the same size and a little lighter than the average adult human.
		It is known that the porpoises' echolocation is sufficiently discriminating to detect the presence of the nets, but this does not stop porpoises from becoming trapped.

	Harbour Porpoise
		The harbour porpoise is a short, stocky toothed cetacean that inhabits cool coastal waters of the northern hemisphere.
		Sides of the harbour porpoise are mottled gray, the dorsal side is dark grey and the underbelly is white.
		Although harbour porpoise have been spotted in deep water, they tend to remain in shallower inshore waters where they are most often observed in small groups of one to three animals.

		Although harbour porpoises were believed to be extinct throughout the Mediterrenean, there is some evidence indicating that they may yet exist in the Aegean Sea, close to the entrance to the Black Sea where porpoises are still found.
		Harbour porpoises have been considered extinct from the Mediterranean Sea since the begining of the 19th century, or even earlier.
		In view of the significance of a discrete harbour porpoise population in the Aegean, our priority is to conduct dedicated surveys (using joint acoustic/visual methods) to determine the extent of this "population".

	Cetacean Species - Harbour Porpoise
		The swimming motion of the harbour porpoise is usually inconspicuous, involving surfacing with a rolling motion, although the animals occasionally surface with a vigorous vertical motion causing a splash.
		The harbour porpoise is found in cold temperate and sub-arctic waters of the Northern Hemisphere, commonly inhabiting shallow coastal bays, estuaries and tidal channels of the Atlantic coast of Europe, east and west coasts of North America and the Pacific coast of Asia.
		Harbour porpoises reach sexual maturity at an age of 3 to 6 years, and at body lengths of about 1.35 m in males and 1.45 m in females.

	CMS: Phocoena phocoena, Harbour porpoise
		Harbour porpoises are seldom found in waters with an annual average temperature above 17°C. In some areas, especially on the East coast of Scotland, agonistic interactions with bottlenose dolphins (Tursiops sp.) may play a role in determining the limits of the range.

	The potential effects of fishing on bottlenose dolphin and harbour porpoise
		A study of incidental catch of harbour porpoise in SW Bay of Fundy (Canada), for example, suggested that significant changes in length frequencies of the porpoises could be attributed to the fishery, and that sustained adult mortality in the gill-net fishery may have compressed the size, and possibly the age structure of the population
		Given the slow reproductive rate of the harbour porpoise, these catches were considered to be a serious threat to the relatively discrete harbour porpoise population in the area.
		It is considered that this is the most frequent cause of death of stranded harbour porpoise in the UK and, with their slow reproductive rate, means that there could be a serious threat to sustainability of discrete populations.

		The life expectancy of harbour porpoises is around 13 years, but today few seem to live past the age of 8.
		Harbour porpoises prefer water temperatures in the range 5-16°C. Areas which have a great deal of turbulence or changes of currents also have a high concentration of zooplankton which attracts a variety of species, including harbour porpoises.
		Dolphins and porpoises can be affected by power boats and personal watercraft (commonly known as jet skis), either directly from injuries received in collisions, or indirectly through noise generated underwater by the craft's propulsion interfering with their echo-location systems.

	Species at risk - Harbour Porpoise
		Harbour Porpoises are among the smallest whales; in eastern Canada few individuals exceed 1.7 m in total length.
		The Harbour Porpoise Northwest Atlantic population is made up of four discrete sub-populations; three in Canadian waters (Newfoundland-Labrador, Gulf of St. Lawrence, and Bay of Fundy-Gulf of Maine), and one off the western coast of Greenland.
		The most important recent threat to Harbour Porpoises in eastern Canada is bycatch in bottom-set gill nets used to capture groundfish; this threat has decreased substantially with the depletion of groundfish stocks and consequent reductions in fishing.

	Harbour Porpoise, Canada
		The Harbour Porpoise Release Programme (HPRP) was developed by the Grand Manan Whale and Seabird Research Station (GMWSRS) in 1991 to assist local fishermen in the Bay of Fundy, Canada with the safe release of harbour porpoises from their herring weirs.
		This designation is the result of the historically high incidental mortality of porpoises in the sink gill net fisheries which operate in the Bay of Fundy and Gulf of Maine as well as the susceptibility of this coastal species to negative impacts from development.
		Porpoises are one of the smallest cetaceans, and this small body size limits the amount of extra energy they can carry in the form of fat.

	Harbour porpoise - Phocoena phocoena: More Information - ARKive
		The harbour porpoise is the most commonly seen porpoise (1), and is the most widely distributed of all cetaceans (whales and dolphins) in northern Europe (5).
		At birth, young harbour porpoises are dull in colour and typically have 'birth lines', which look like folds in the skin, and persist for the first few hours after birth (4).
		A UK Biodiversity Action Plan priority species, the harbour porpoise is protected in UK waters by the Wildlife and Countryside Act 1981 and the Wildlife (Northern Ireland) Orders, 1985; it is illegal to intentionally kill, injure, or harass any cetacean (whale or dolphin) species in UK waters (3).

	Harbor Porpoise
		The Harbor Porpoise (Phocoena phocoena) is the most widely seen porpoise, sometimes earning it the nickname "common porpoise." The Harbor Porpoise belongs to the Cetacean family, a division of water-dwelling mammals that must breathe oxygen.
		The mother porpoise then nurses the calf for at least eight months, and the young porpoise is able to eat some solid food at about three months of age.
		Unlike dolphins, porpoises are very shy animals, traveling alone or in very small groups and not playing in the waves or approaching boats and people.

	Grand Manan Whale & Seabird - harbour porpoise release news 1998
		The Harbour Porpoise Release Program was started in 1991 to assist local weir fishermen with the safe removal of porpoises from their weirs.
		We successfully released (or the porpoises swam out on their own) 31 of 34 porpoises, two died during seining process, and the fate of one was unknown (see Table 2).
		There is a great degree of variability in the ways porpoises react to the seining and handling process; some individuals appear to become more stressed than others and this may affect their chance of survival during the seining process.
