Significance Bottom trawling is the most widespread source of physical disturbance to world’s seabed. Predictions impacts are needed underpin risk assessment, and they relevant for fishing industry, conservation, management, certification bodies. We estimate depletion recovery seabed biota after by fitting models data from a global compilation. Trawl gears removed 6–41% faunal biomass per pass, times posttrawling were 1.9–6.4 y depending on fisheries environmental context. These results...
Significance We conducted a systematic, high-resolution analysis of bottom trawl fishing footprints for 24 regions on continental shelves and slopes five continents New Zealand. The proportion seabed trawled varied >200-fold among (from 0.4 to 80.7% area depth 1,000 m). Within 18 regions, more than two-thirds remained untrawled during study periods 2–6 years. Relationships between metrics total trawling activity footprint were strong positive, providing method estimate where data are not...
Abstract Bottom‐contact fishing gears are globally the most widespread anthropogenic sources of direct disturbance to seabed and associated biota. Managing these disturbances requires quantification gear impacts on biota rate recovery following disturbance. We undertook a systematic review meta‐analysis 122 experiments effects‐of‐bottom quantify removal benthos in path estimate rates A pass reduced benthic invertebrate abundance by 26% species richness 19%. The effect was strongly...
Abstract Derelict abandoned, lost and discarded fishing gear have profound adverse effects. We assessed gear-specific relative risks from derelict to rank-order methods based on: production rates, quantity indicators of catch weight grounds area, consequences gear. The latter accounted for ghost fishing, transfer microplastics toxins into food webs, spread invasive alien species harmful microalgae, habitat degradation, obstruction navigation in-use gear, coastal socioeconomic impacts....
Abstract More than 50% of the world's total marine catch (approximately 81 million tonnes) is harvested using towed fishing gears (i.e. Danish seines, dredges and otter beam trawls). As for all methods, mortality these comprises reported (landed) unreported other unaccounted, collateral deaths due to (i) avoiding, (ii) escaping, (iii) dropping out gear during fishing, (iv) discarding from vessel, (v) ghost lost gear, (vi) habitat destruction or subsequent (vii) predation (viii) infection any...
Cryptic, not readily detectable, components of fishing mortality are routinely accounted for in fisheries management because a lack adequate data, and some components, accurate estimation methods. Cryptic mortalities can cause adverse ecological effects, source wastage, reduce the sustainability fishery resources and, when unaccounted for, errors stock assessments population models. Sources cryptic (1) pre-catch losses, where catch dies from operation but is brought onboard gear retrieved,...
Abstract Bottom trawling is the most widespread human activity directly affecting seabed habitats. Assessment and effective management of effects bottom at scale fisheries requires an understanding differences in sensitivity biota to trawling. Responses disturbance are expected depend on intrinsic rate increase populations ( r ), which be linearly related reciprocal longevity. We examine relationship between longevity benthic invertebrates their response trawling; both terms immediate...
Abstract Bottom trawling accounts for almost one quarter of global fish landings but may also have significant and unwanted impacts on seabed habitats biota. Management measures voluntary industry actions can reduce these impacts, helping to meet sustainability objectives fisheries, conservation environmental management. These include changes in gear design operation trawls, spatial controls, impact quotas effort controls. We review nine different use published studies a simple conceptual...
Abstract Discarding by fisheries is one of the most wasteful human marine activities, yet we have few estimates its scale. Reliable global discards are essential for sustainable management. Using United Nations Food and Agriculture Organization databases on country-specific landings, estimated discard rate magnitude estuarine capture using fishery-specific rates derived from direct observations gear-specific within a Bayesian modelling framework. An 9.1 million tonnes discarded annually (95%...
Significance We estimated the biological state of seabed sedimentary habitats, with specified uncertainty, in 24 trawled regions worldwide. Seabed status differed greatly among (from 0.25 to 0.999, relative an untrawled 1); 15 had average > 0.9. Two-thirds all assessed area was = 1, 93% 0.8, but 1.5% 0. The total swept by trawling a strong driver regional status, providing relationship predict from amount trawling. is high where fisheries are exploited sustainably—emphasizing that good...
Abstract Mobile bottom contact gear such as trawls is widely considered to have the highest environmental impact of commonly used fishing gears, with concern about on benthic communities, bycatch, and carbon footprint frequently highlighted much higher than other forms fishing. As a result, use gears has been banned or severely restricted in some countries, there are many proposals implement restrictions elsewhere. In this paper, we review sustainability trawling respect target-species...
When synthetic non-biodegradable fishing nets are lost, abandoned or discarded at sea, they may continue to catch fish and other animals for a long period of time. This phenomenon is known as 'ghost fishing'. Biodegradable nets, on the hand, intended degrade decompose after certain time under water thereby lose their ghost capacity more quickly than conventional gear. A biodegradable net material, blend 82% polybutylene succinate (PBS) 18% adipate-co-terephthalate (PBAT), was developed. We...
Summary Impacts of bottom fishing, particularly trawling and dredging, on seabed ( benthic ) habitats are commonly perceived to pose serious environmental risks. Quantitative ecological risk assessment can be used evaluate actual risks help guide the choice management measures needed meet sustainability objectives. We develop apply a quantitative method for assessing by towed bottom‐fishing gears. The is based simple equation relative status (RBS), derived solving logistic population growth...

Technical such as gear restrictions are commonly used management. Many the aimed primarily at protecting juveniles.

Bycatch in fisheries can have profound effects on the abundance of species with relatively low resilience to increased mortality, alter evolutionary characteristics and concomitant fitness affected populations through heritable trait-based selective removals, ecosystem functions, structure services food web trophic links. We challenge current piecemeal bycatch management paradigms, which reduce mortality one taxon conservation concern at unintended expense others. mitigation measures may...
Abstract Bottom trawl fisheries are the most widespread source of anthropogenic physical disturbance to seabed habitats. Development fisheries‐, conservation‐ and ecosystem‐based management strategies requires selection indicators impact bottom trawling on state benthic biota. Many have been proposed, but no rigorous test a range candidate against nine commonly agreed criteria (concreteness, theoretical basis, public awareness, cost, measurement, historical data, sensitivity, responsiveness,...
There has been increasing recognition of the need to address adverse ecological and socioeconomic effects abandoned, lost discarded fishing gear (ALDFG). This component marine debris progressively problematic over recent decades with rapid expansion global fisheries' footprint effort, transition synthetic more durable materials for components. ALDFG drivers consequences vary substantially by type, region, scale individual fishery within these other broad categories, including robustness...
Studies on herring,Clupea harengus (L.), were conducted in the northern Baltic to assess whether mortality of herring escaping through a rigid sorting grid (12 mm bar spacing) placed front codend was different from that 36 diamond mesh codend. Escapees collected into netting cages, and subsequently transferred large holding cages (85 m3) where they held for up two weeks mortality. 76–100% small (<12 cm) 44–83% (12–17 escapees dead after 7 days. The 14-day mortalities 96–100% 77–100%...
