  abstract = {{D}rifting fish aggregating devices (d{FAD}s) are widely used in tropical tuna purse seine fisheries to aggregate fish and make them easier to catch. {T}he use of d{FAD}s has been associated with a number of potential positive and negative impacts, touching on a range of ecological, economic and social issues. {O}ne negative environmental impact of d{FAD}s is that they have the potential to wash ashore and become grounded or beached, potentially causing damage to marine habitats. {H}owever, other than anecdotal reports, this issue has received very little research attention to date. {T}he lack of research on this topic means that the problem of beaching d{FAD}s is not well defined, with the risk of beaching events mostly assumed and the extent and severity of impacts uncertain. {T}he aim of this paper is to better characterise the potential problem of beaching d{FAD}s. {W}e examine the potential for d{FAD} beaching events to occur, which is determined by location of deployment, dispersal patterns, extent of efforts to prevent beaching events from occurring and, to a lesser extent, d{FAD} design. {T}his discussion is illustrated with a case study examining the spatio-temporal dynamics of d{FAD} trajectories in the {I}ndian {O}cean and estimating the frequency of d{FAD} beaching events on coral reefs. {T}he potential environmental impacts of beached d{FAD}s are reviewed by looking at wider literature on other abandoned, lost, or otherwise discarded fishing gear, and we offer some thoughts on the classification of d{FAD}s as marine pollution. {F}inally, we critically discuss a number of possible ways to reduce the number of d{FAD} beaching events on sensitive marine habitats. {T}his includes regulatory measures, which would be applied by the tropical tuna {R}egional {F}isheries {M}anagement {O}rganisations or coastal and island state governments and advances in d{FAD} design, which would likely come from collaboration between fishing companies, researchers and {NGO}s/non-profit partnerships. {P}ossible measures include reducing the overall number of d{FAD}s in the water, i.e. though deployment limits, fee structures and reduced fleet capacity, or a localised reduction of d{FAD} deployments in sensitive areas; reduced lifetime of d{FAD}s, through use of entirely bio-degradable materials; and the prevention of d{FAD}s entering areas with sensitive habitats, through recovery initiatives (at sea and inshore) and innovative d{FAD} design.},
