Megaptera novaeangliae (Humpback whale)

Multivariate analysis of behavioral response experiments in humpback whales (Megaptera novaeangliae)

Study Type: 

wild

Location: 

Australia

Target catch: 

N/A

Effect on bycatch species: 

Humpback whales responded to 'tones' by moving offshore and surfacing more often, perhaps trying to avoid the stimuli. Responses to social sounds were more variable.

Acoustic investigation of bycatch mitigation pingers

Study Type: 

wild

Location: 

Queensland, Australia

Target catch: 

Shark

Effect on bycatch species: 

The current net/pinger configuration is adequate for humpback whales, dugongs and dolphins swimming at normal travelling speeds. The current pinger spacing is insufficient for dolphins swimming straight at the net at high speeds.

Migrating humpback whales show no detectable response to whale alarms off Sydney, Australia

Study Type: 

wild

Location: 

Cape Solander, Sydney Australia

Target catch: 

N/A

Effect on bycatch species: 

There were no differences in behavior of migrating whales when alarms were on or off

Implications of fishing rope strength on the severity of large whale entanglements

Study Type: 

wild

Location: 

US east coast and Canadian Maritimes

Target catch: 

Various

Effect on bycatch species: 

Ropes with a breaking strength of 1,700 lbs or less could reduce life-threatening entanglements of North Atlantic Right whales by at least 72%. Right and humpback were entangled in ropes with stronger breaking strength than those involving minke whales.
