  1. Use shark liver oil to reduce seabird bycatch

    A replicated, controlled experiment off the coast off north-east New Zealand (Pierre & Norden 2005) found that the number of dives made by seabirds in pursuit of pilchard baits behind a longline fishing vessel was dramatically lower (< 5 birds/min) when small quantities of shark liver oil were dripped onto the water behind the vessel than during control trials using vegetable oil (always > 30 birds/min) or sea water (20-40 birds/min). Diving birds were mainly flesh-footed shearwaters Puffinus carneipes, but also Buller's shearwaters Puffinus bulleri and white-faced storm petrels Pelagodroma marina.
