Pair Trawling vs. Otter Trawling: An evaluation of efficiency along the Southwest Coast of India [PDF]
, 2021 In Karnataka, the trawling industry contributes significantly to fish landings. Though conventional otter trawlers account for the majority of trawl landings in the state, pair/bull trawling, which is prohibited, also during the post-monsoon season ...

Scientia Marina, 2004 The Mediterranean fishery has experienced a decline in catches over the past 20 years due to an excessive increase in effort caused by both increased trawler engine power and rapid technological advances in fishing technology and fish location.

Inshore small-mesh trawling survey of the Cape south coast. Part 2. Occurrence of estuarine-associated fishes [PDF]
, 1984 Marine inshore trawl catches of 12 species of estuarine-associated fishes are reported together with their depth and length distributions. Underwater observations of four additional species, made during 122 SCUBA dives over rocky substrates, are also ...

Limnology and Oceanography: Methods, EarlyView.Abstract Accurate length data underpin many ecological and physiological analyses, from assessing population size structure to parameterizing biomass and bioenergetic models. Stereo‐baited remote underwater video systems (stereo‐BRUVs) provide a non‐intrusive means of collecting these data in situ, supporting management and conservation of motile ...

Distribution of Bottom Trawling Effort in the Yellow Sea and East China Sea.
PLoS ONE, 2016 Bottom trawling is one of the most efficient fishing activities, but serious and persistent ecological issues have been observed by fishers, scientists and fishery managers. Although China has applied the Beidou fishing vessel position monitoring system (

Reconstructed Russian Fisheries Catches in the Barents Sea: 1950-2014
Frontiers in Marine Science, 2018 The management of marine living resources that straddle country borders has historically been a challenge, particularly in cases where political tensions are high.

Tracking the impact of bottom trawling on benthic habitat status. [PDF]
Conserv BiolAbstract Bottom trawling is the most widespread physical disturbance to marine benthic habitats, yet broadscale assessments of its impact remain limited. We developed a quantitative framework to evaluate trawling effects on benthic habitats at broad spatial scales based on the sentinels of seabed (SoS) indicator.

Automatization of multistep sample preparation for microplastics monitoring in aquatic environments
Limnology and Oceanography: Methods, EarlyView.Abstract Microplastics (MP) have been found in every environmental compartment in urban and remote areas. Although their ubiquity is widely recognized, the lack of harmonized protocols for sampling, sample preparation, and particle identification/quantification hinders comparability among studies.

Journal of Marine Science and Engineering, 2023 Measuring the distribution of the fishing effort of trawlers is of great significance for describing marine fishery activities, quantifying fishing systems in terms of marine ecological pressure, and revising the regulations of fishing.
