==Description==
Bottom trawling consists in towing a fishing net along the sea floor to catch fish or other marine species. Bottom trawling can be contrasted with midwater trawling (also known as [[Industrial and Pelagic Trawl Catch|pelagic trawling]]), where a net is towed higher in the water column. Trawling is done by a trawler, which can be a small open boat with only 30 hp (22 kW) or a large factory trawler with 10,000 hp (7,500 kW). Bottom trawling can be carried out by one trawler or by two trawlers fishing cooperatively (pair trawling).
Small scale coastal fishing is composed, typically, by family-based businesses, where owners are directly involved in the fishing activity. Together with other maritime activities, small-scale fisheries play an important role in local economies.

Small-scale fisheries are especially important in the Mediterranean, where over half of the sector is concentrated and where it has been playing a dominant role in the livelihoods of coastal communities for centuries.

Description

Small scale coastal fishing is composed, typically, by family-based businesses, where owners are directly involved in the fishing activity. Together with other maritime activities, small-scale fisheries play an important role in local economies.

Small-scale fisheries are especially important in the Mediterranean, where over half of the sector is concentrated and where it has been playing a dominant role in the livelihoods of coastal communities for centuries.

MSP Challenge

Small Scale Coastal Catch is a month-by-month, computer-generated data layer following this fleet's fishing catch calculated by the ecosystem simulation. This fleet doesn't fish in areas that are protected against small scale coastal fisheries.

A plan can also include a change in the fishing efforts for this fleet per EEZ. Activate the Fishing controls by ticking the appropriate checkbox under section 2b in the Plan Wizard. Subsequently, change the Fishing effort sliders under the Fishing tab of the Plan Details (maximize the Plans Monitor and select your plan)
