“…As a consequence, later studies included a larger proportion of less industrialized fisheries with less well developed management regimes, where gear loss rates can typically be higher. The interaction between geography and study date is likely the main driver in the consistent increases observed in gear losses with time ( Figures 5-7 A possible additional and/or alternative explanation for the increase in gear losses with time is the significant increase in global fishing effort from the 1970s through 2010 and the stabilizing of this effort over the last decade (Bell, Watson, & Ye, 2017;Watson & Tidd, 2018). Perhaps unsurprisingly, a correlation between fishing effort and quantities of gear lost has been found (Richardson, Gunn, Wilcox, & Hardesty, 2018;Yıldız & Karakulak, 2016).…”

“…With fish estimated to provide nearly 20% of the animal protein consumed by humans around the world, ensuring global seafood security becomes increasingly important as the world's population continues to grow (FAO, 2018). These impacts can exacerbate existing pressures on fishers experiencing diminishing economic returns, as fish stocks are depleted and illegal fishing is on the rise (Watson & Tidd, 2018). Fisheries impacts from ALDFG include damage to and loss of fishing gear and catch, and hazards to navigation and safety at sea (Gilman, 2015;Macfadyen, Huntington, & Cappell, 2009;Scheld, Bilkovic, & Havens, 2016).…”

Estimates of fishing gear loss rates at a global scale: A literature review and meta‐analysis

Abandoned, lost or otherwise discarded fishing gear (ALDFG) represents a significant, yet ultimately unknown amount of global marine debris, with serious environmental and socioeconomic impacts. This study reviews 68 publications from 1975 to 2017 that contain quantitative information about fishing gear losses. Gear loss estimates reported by the studies ranged widely, with all net studies reviewed reporting annual gear loss rates from 0% to 79.8%, all trap studies reporting gear loss rates from 0% to 88%, and all line studies reporting gear loss rates from 0.1% to 79.2%. Information obtained from this review was used to perform a meta‐analysis that provides the first synthetic, statistically robust estimates of global fishing gear losses. The meta‐analysis estimates global fishing gear losses for different major gear types. We estimate that 5.7% of all fishing nets, 8.6% of all traps, and 29% of all lines are lost around the world each year. Furthermore, we identified key gear characteristics, operational aspects and environmental contexts that influence gear loss. These estimates can be used to support sustainable fisheries development through informing risk assessments for fisheries and monitoring and assessment efforts to reduce gear losses.

“…Coastal and offshore ecosystems are changing rapidly (McCauley et al, 2015), at a time when the history of fisheries management includes some successes and some highly publicized failures (Beddington, Agnew, & Clark, 2007;Pinsky, Jensen, Ricard, & Palumbi, 2011;Worm et al, 2009). The global wild fish catch peaked in the 1990s and is now declining (Pauly & Zeller, 2016;Watson & Tidd, 2018). Addressing these issues potentially involves both improved fisheries management and the application of 'no-take' marine protected areas (MPAs), i.e.…”

Abstract1. A continuing debate between environmental scientists and fisheries biologists on the sustainability of fisheries management practices, and the extent of fishing impacts on marine ecosystems, is unlikely to be resolved without fisheryindependent data spanning large geographic and temporal scales. Here, we compare continental-and decadal-scale trends in fisheries catches with underwater reef monitoring data for 533 sites around Australia, and find matching evidence of rapid fish-stock declines.2. Regardless of a high global ranking for fisheries sustainability, catches from Australian wild fisheries decreased by 31% over the past decade. The biomass of large fishes observed on underwater transects decreased significantly over the same period on fished reefs (36% decline) and in marine park zones that allow limited fishing (18% decline), but with a negligible overall change in no-fishing marine reserves. Populations of exploited fishes generally rose within marine reserves and declined outside the reserves, whereas unexploited species showed little difference in population trends within or outside reserves.3. Although changing climate and more precautionary fisheries management contribute to declining fish catches, fisheries-independent transect data suggest that excessive fishing also plays a major role.4. The large number of fishery stocks that remain unmanaged or have poor data, coupled with continuing declines in the stock biomass of managed fish species, indicate that Aichi Target 6 of the Convention on Biological Diversity (i.e. 'by 2020, all fish and invertebrate stocks and aquatic plants are managed and harvested sustainably') will not be achieved in Australia, or elsewhere.5. In order to maintain some naturally functioning food webs supported by large predators and associated ecosystem services in this era of changing climate, a greatly expanded network of effective, fully protected marine protected areas is needed that encompasses global marine biodiversity. The present globally unbalanced situation, with >98% of seas open to some form of fishing, deserves immediate multinational attention.
