“…Globally, little published information exists about the number of marine mammals caught in trawl nets (Fertl & Leatherwood, 1997). Incidental take of marine mammals (pinnipeds) during trawl operations has received attention in several countries, including Australia (Shaughnessy & Davenport, 1996), South Africa (Shaughnessy & Payne, 1979), USA (Alaska) (Perez & Loughlin, 1991), Canada (Pemberton et al, 1994) and Argentina (Romero et al , 2011). However, no previous information exists about the interaction between trawling fisheries and O. flavescens along the South Pacific.…”

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.

“…Fur seals, especially young animals, have a tendency to investigate any object in the ocean includmg fishing nets (Shaughnessy and Davenport 1996). Interactions with fishing gear are often associated with attempts by the seals to feed on the fish nets.…”
