No evidence of cryptic bycatch causing New Zealand sea lion population decline
In PNAS, Meyer et al. (1) analyze whether exclusion devices in trawl nets contributed to New Zealand sea lion (NZSL; Phocarctos hookeri) population decline at the Auckland Islands. We refute the primary conclusion from their correlative assessment: that annual pup production changes (as a measure of...
