Dear Colleagues,
We would like to inform you of a new publication now available at Journal of
the marine biological association of the United Kingdom
P. Reyes; R. Hucke-Gaete & J.P. Torres-Florez. First observation of operational
interactions between bottom-trawling fisheries and South American sea lion,
Otaria flavescens in south-central Chile.
Abstract This paper presents results of a study conducted on the trawling
industrial fishery fleet of Merluccius gayi in south-central Chile, and the
resulting interactions with the South American sea lion (Otaria flavescens).
This study is based on observations made during September 2004, when incidental
sea lion catch in the trawls was 6.3 sea lions/working day (1.2 sea
lions/trawl−1). A total of 82 animals were incidentally caught, of which 12
were found dead, and the 70 remaining suffered from internal bleeding and/or
fractures as a result of their capture. 83.3% of the fatalities occurred during
nocturnal trawls, which comprise 30% of all observed trawls. Possible
mechanisms of sea lion take are discussed. This note presents the first records
of sea lions incidental by-catch by the trawler fleet along the south-east
Pacific coast of Chile.
