description | The dusky dolphin (Lagenorhynchus obscurus) inhabits the temperate waters of the continental shelf and slope off Peru, Chile, Argentina, New Zealand, southwestern Africa, and several offshore island groups. The biology and ecology of this species in Argentine waters has been described. Our study area covered the waters off the Patagonian coast from San Antonio Oeste (40 degree 44 theta S) to Cabo Guardian, south of Puerto Deseado (48 degree 10 theta S). This large area was selected because the objective of the surveys was to assess abundance for three species: short-beaked common dolphin (Delphinus delphis), dusky dolphin, and Commerson's dolphin (Cephalorhynchus commersonii). Another objective of the program was to assess interactions between fisheries and marine mammals, since this area is under relatively intense coastal and offshore fishing activity. |
