Overview

Comprehensive assessment of dolphin strandings and feeding ecology reveals implications for fisheries management.

Key Points

  • This research aims to assess the stranding patterns and feeding ecology of common bottlenose dolphins along the Portuguese coast.
  • Analyzed 264 strandings from 1980 to 2019
  • Conducted stomach content analysis on 43 dolphins from 1997 to 2019
  • Examined dietary habits and species interactions with fisheries
  • Stranding events peaked in the first half of the year, increasing in recent decades
  • Diet analysis revealed over 85% of diet comprised of fish, primarily hake and conger eel
  • Significant dietary overlap with commercially targeted species indicates potential competition with fisheries
