A dataset from bottom trawl survey around Taiwan [PDF]

ZooKeys, 2012
Bottom trawl fishery is one of the most important coastal fisheries in Taiwan both in production and economic values. However, its annual production started to decline due to overfishing since the 1980s.

Spatiotemporal Patterns of Fish Diversity in the Waters Around the Five West Sea Islands of South Korea: Integrating Bottom Trawl and Environmental DNA (eDNA) Methods [PDF]

Animals
The waters surrounding the Five West Sea Islands of South Korea are ecologically important but challenging to survey due to their location within a strategic military zone, strong tidal currents, and significant tidal variation.

Improving an endangered marine species distribution using reliable and localized environmental DNA detections combined with trawl captures [PDF]

Scientific Reports
The description of marine fish distributions generally relies on trawl survey observations. For rare species, sporadic catches necessitate the combination of multiannual trawl surveys to accurately describe the distribution, limiting short term ...

Evaluating the potential of underwater television to contribute to marine litter assessments alongside bottom trawling. [PDF]

PLoS ONE
Marine litter presents a global threat to marine ecosystems, human health, and safety. Therefore, it is important to increase our knowledge about spatiotemporal trends of litter in the environment.

Assessing survey design changes of long-term fishery-independent groundfish trawl surveys in the Gulf of Mexico

Frontiers in Marine Science
Long-term fishery-independent surveys provide a wealth of information on fisheries stocks that inform stock assessments. One of the strengths of these surveys is that the design and methods are consistent through time.

Autumn distribution of Bristol Bay red king crab using fishery logbooks. [PDF]

PLoS ONE, 2018
Spatial distributions of fished species must be well characterized to avoid local depletions, identify critical habitat, and predict and mitigate interactions with other fisheries. The Bristol Bay red king crab (Paralithodes camtschaticus) fishery is one
