Abstract:
Derelict fishing nets comprise a significant amount of the marine debris
in the world’s oceans and on its shorelines. These ‘ghost nets’ result
in economic losses for the fishing industry, pose hazards to navigation
at sea, and can entangle marine and terrestrial wildlife. Ghost nets are
an acute problem along Australia’s northern coastline, with most nets
originating from Southeast Asian fishing vessels outside Australia’s
Exclusive Economic Zone (EEZ). To understand the causes of gear loss and
identify tractable solutions to this transboundary problem, Australian
and Indonesian fishers (N = 54) were asked why, when and in what
circumstances and conditions they are likely to lose gear. Fishers
identified snagging of nets (78%) and gear conflicts (19%) as the main
causes of gear loss. These interviews informed the development of a
fault tree, as a tool to identify the chain of events that result in
gear loss or abandonment. The fault tree analysis provides
recommendations for interventions and improvements in regional fisheries
management to reduce fishing gear loss ultimately resulting from
overcrowding, overcapacity and illegal, unreported and unregulated
Fishing (IUU).
