Dear colleagues,
On behalf of my co-author and myself, I am delighted to bring to your
attention the publication of our last research published by the
scientific journal /Oceans/ *2024*, /5/(3), 429-441;
https://doi.org/10.3390/oceans5030025
The paper summarizes 13 years of cetaceans' strandings along the
Bulgarian coast in the western Black Sea.
*Abstract*: Cetacean strandings are valuable sources of data about their
life history, health status, population trends, and impact of threats.
We examined the strandings along the Bulgarian coast of the Black Sea
for a period of 13 years from 2010 to 2022. A total of 1528 cetacean
strandings of all three species inhabiting the basin were recorded: 1031
harbour porpoises Phocoena phocoena, 199 bottlenose dolphins Tursiops
truncatus, 97 common dolphins Delphinus delphis, 19 delphinids and 182
unidentified. The highest numbers were observed in 2016 and 2022.
Monthly peaks for harbour porpoise and bottlenose dolphin were in July
and August and for common dolphin in May. An unusually high mortality of
porpoise neonates was recorded in 2015 and 2016. The overall sex ratio
showed a slightly higher share of males at 120:100. This bias was the
most pronounced for males of common dolphins. Spatial distribution
varied interspecifically but was predominantly along the southern coast.
Bycatch signs were detected in 80 animals including during the turbot
fishing ban period, suggesting the existence of illegal fishing
operations. All of this highlights the need for better reinforcement and
control to ensure both the conservation of endangered cetaceans and the
sustainability of fisheries. Improvement in data collection is needed to
improve the quality of information.
