Echolocation behaviour of a harbor porpoise and six finless porpoises was recorded in open-water systems using acoustic data loggers (A-tag). In total 1359 click trains were recorded during 4.6 h…
The study was based on stomach content of four harbour porpoises bycaught in the coastal fishery in 2004 and 2006, on the Marmara Sea coast. Three fish species, horse mackerel…
The distribution of harbour porpoises Phocoena phocoena in southern Europe and along the Atlantic African coast is poorly understood, with tentative assessments suggesting a discrete West African population with a…
Reduction of harbour porpoise bycatch by use of high-density iron-oxide (IO) gillnets was tested in sea trials in the Danish North Sea bottom set gillnet fishery in September–October 2000. The…
The study was based on stomach content from 42 harbour porpoises bycaught or stranded between April to June in 2002 and 2003, on the Turkish western Black Sea coast. Seven…
Using auditory evoked potential (AEP) methods, a study was conducted on a harbour porpoise (Phocoena phocoena) at the Dolfinarium Harderwijk in The Netherlands. The study measured the audible range of…
The ecological and conservation status of the geographically isolated Black Sea harbour porpoise is currently unknown. Although it has been suggested that Black Sea harbour porpoises are distinct from other…
(...) Recently, MacLeod et al. (2007) analysed data from harbour porpoises (Phocoena phocoena) stranded on Scottish North Sea coasts in March–May of 1993–2003. Comparing 2002–2003 data against baseline data from…
Circulating cortisol levels are accepted as a sensitive indicator of acute stress in marine mammals, particularly in relation with capture and handling. The present study provides the first long-term monitoring…
The target strength as a function of aspect angle were measured for four species of fish using dolphin-like and porpoise-like echolocation signals. The polar diagram of target strength values measured…
