Fishing effort and observed captures of New Zealand sea lion by month, 2002–03
In the 2002–03 fishing year, there was no observed fishing in purse seine fisheries. No estimates of total interactions were made.
In the Auckland Islands squid fishery, trawl nets are currently required to be fitted with sea lion exclusion devices (SLEDs). These are grids that prevent the sea lions from entering the cod end, with a hole in the net that is designed to allow the sea lions to escape. Estimated interactions are the captures that would have been observed, had observers been present on all vessels, and had SLEDs not been used. In fisheries that don't use SLEDs, interactions are equivalent to captures.
