Noxious bait

Bait that is treated with compounds intended to make it unpalatable to non-target species (http://bycatch.org/articles/results-1986-87-california-sea-lion-steelhea...). For example, a type of olfactory deterrent used for seabird avoidance. Biogenic chemical deterrents that can be made from fish liver oil are released behind the vessel on the surface of the water as longlines are being set (http://bycatch.org/articles/reducing-seabird-bycatch-longline-fisheries-...).
