Исследовано содержимое желудков у 157 выброшенных на побережье и случайно пойманных в рыболовные сети черноморских китообразных, включая 123 азовок (Phocoena phocoena relicta), 26 белобочек (Delphinus delphis ponticus) и 8 афалин (Tursiops truncatus ponticus) из вод Украины, Болгарии, Грузии и России. Зарегистрированы новые объекты питания для азовки – пиленгас (Liza haematocheila) и спикара (Spicara flexuosa), а также один вид для белобочки и афалины – сарган (Belone belone euxini). Показано, что в современных условиях основными пищевыми объектами морских свиней в водах Украины являются шпрот (Sprattus sprattus phalaericus), мерланг (Merlangius merlangus euxinus) и хамса (Engraulis encrasicolus). Общий список рыб, входящих в рацион черноморских... |

There is increasing evidence from previous studies, and from fishers' observations, that coastal dolphins use fishing nets as an easily accessible feeding source, damaging or depredating fish caught in the nets. This study investigates the impact of dolphin depredation on artisanal trammelnets by analysing the catch composition of 614 artisanal fishing operations in the Bonifacio Strait Natural Reserve (France). Common bottlenose dolphins (Tursiops truncatus) attacked, on average, 12.4% of the nets and damaged 8.3% of the catch. However, attacked nets were characterized by statistically significantly higher catch per unit effort than unattacked ones. Catch composition also differed significantly after dolphin attacks; bentho-pelagic fish were more... |

Residence patterns, habitat use, range, and some population estimate of the coastal bottlenose dolphin, Tursiops truncatus (Montagu, 1821), were documented in two coastal sites in southern Brazil: Laguna (Santa Catarina) (28º30'S; 48º55'W), and Imbe/Tramandai (Rio Grande do Sul) (29º58'S; 50º07'W). Regular observations were carried out at the Laguna system for 27 months (August 1989 to December 1991). The dolphins were photo-identified using natural permanent marks. Over 4,500 photograps were taken from shore grounds 6 to 14 meters away. Up to 51 dolphins have used the estuaries of Laguna's canal and Imarui-Santo Antonio's lagoon system in 1991. A stable group of nine animals has inhabited the Imbe/Tramandai area for over 13 years. Both sites were... |
