369-373 Passive acoustic deterrents in the form of chains of metallic beads and air-filled plastic tubing attached to gillnets in Australia did not reduce bycatch of two small cetaceans: the Atlantic bottlenose dolphin (Tursiops truncatus) and Spinner dolphin (Stenella longiristris). A sub-surface set gillnet (set 4.5 m below the surface) in Australia reduced cetacean catch rate [Atlantic bottlenose dolphin (Tursiops truncatus) and Spinner dolphin (Stenella longiristris)] when compared to a standard surface set net. The sub-surface net decreased total fish (teleost species: tuna, mackerel, billfish) and shark catch approximately 25%.
| Location | Fishing gear | Reduction technique | Bycatch species | Effect on bycatch species | Catch | Effect on target catch | Type |
| Australia | Gillnets | Passive acoustic deterrents | Small Cetaceans (maximum length < 7.5 meters) | Did not reduce bycatch | Trout | In the wild | |
| Australia | Gillnets | Sub-surface sets | Small Cetaceans (maximum length < 7.5 meters) | Reduced bycatch | Multiple species | Decreased target catch | In the wild |
