Food color and marine turtle feeding behavior: Can blue bait reduce turtle bycatch in commercial fisheries?

Although effective with captive loggerhead (Caretta caretta) and Kemp??˙s ridley (Lepiochelys kempii) sea turtles, blue dyed bait is not effective in reducing olive ridley (Lepidochelys olivacea) and green sea turtle (Chelonia mydas) bycatch in longline fisheries in Costa Rica.
