The Commercial Bottom Trawling Industry in Florida: Balancing Environmental Impact with Economic Contribution

Environmental impact of trawling on the seabed: a review

Fishers have been complaining about the effects of bottom trawl gear on the marine environment since at least the 14th century. Trawl gear affects the environment in both direct and indirect ways. Direct effects include scraping and ploughing of the substrate, sediment resuspension, destruction of benthos, and dumping of processing waste. Indirect effects include post-fishing mortality and long...

Influence of Bottom Trawling on the Normal- Incidence Reflection Coefficient

A North Sea area characterized by muddy, sandy, and gravelly sediments is surveyed with a single-beam echo sounder operating at 12, 38, and 200 kHz. Closely spaced survey legs and a high repetition rate of five sounder pings per second allow the production of echo energy maps with a high spatial resolution. These energy maps reveal a series of string-like features, which are believed to be due ...

Impact of Bottom Trawling on Deep-Sea Sediment Properties along the Flanks of a Submarine Canyon

The offshore displacement of commercial bottom trawling has raised concerns about the impact of this destructive fishing practice on the deep seafloor, which is in general characterized by lower resilience than shallow water regions. This study focuses on the flanks of La Fonera (or Palamós) submarine canyon in the Northwestern Mediterranean, where an intensive bottom trawl fishery has been act...
