Fishing trawler sea

Trawlers are fishing vessels that drag nets through the water to catch fish and seafood, a common method worldwide.

About this subject

Fishing trawlers are vessels designed to operate trawl nets, one of the most widespread fishing methods globally. These cone-shaped nets are towed through the water column (midwater trawling) or along the seabed (bottom trawling). Bottom trawling is often criticized for environmental impacts, such as bycatch of non-target species and damage to marine habitats. In Brazil, the trawling fleet mainly operates on the Southeast and South coasts, catching shrimp, whitemouth croaker, and weakfish.

The history of trawling dates back to the 14th century in Europe, but industrialization occurred in the 19th century with steam-powered boats. Modern trawlers can exceed 30 meters in length, equipped with sonars and hydraulic winches. GPS technology and satellite monitoring enable tracking of routes and fishing grounds. Variations include stern trawlers (with a ramp to haul the net), side trawlers, and twin trawlers, which tow two nets simultaneously.

In Brazil, trawl fishing is regulated by the Ministry of Fisheries and Aquaculture, with closed seasons and exclusion zones. Industrial trawling predominates in the Southeast, while artisanal trawling is common in the Northeast, especially for shrimp. Artisanal fleets use smaller boats, often called 'trawlers' or 'shrimp boats,' operating near the coast. Studies indicate that around 20% of trawl catches in Brazil are discarded as bycatch.

Interestingly, the 'lo-fi disposable camera' style evokes a nostalgic 1990s aesthetic, often associated with everyday records at sea. The image captures a trawler silhouette under a cloudy sky, highlighting the relationship between fishing tradition and modern technology.

Frequently Asked Questions

What is a fishing trawler?

A fishing trawler is a vessel that drags a cone-shaped net through the water to catch fish, shrimp, and other seafood.

What are the environmental impacts of trawling?

Bottom trawling can damage the seabed, and both midwater and bottom trawling produce bycatch, leading to discards of non-target species.

How is trawl fishing regulated in Brazil?

The Ministry of Fisheries and Aquaculture sets closed seasons (defeso) and exclusion zones to protect marine resources.
