Fishing trawler sea

Fishing trawler at sea: a robust vessel used in industrial fishing, dragging nets to catch large volumes of fish in open waters.

About this subject

The fishing trawler is one of the most common types of vessel used in industrial fishing worldwide. Its main feature is the use of a funnel-shaped net, called a trawl, which is dragged through the water behind or between boats. This technique allows capturing large quantities of fish at once, employed both in coastal waters and in the open sea.

Trawling has great economic importance, especially for countries with extensive coastlines, such as Brazil, China, Norway, and the United States. Species like shrimp, hake, cod, and whiting are often targeted. However, the method is also criticized for its environmental impact: the net sweeps everything in its path, including non-target species (bycatch), and damages the seabed, affecting benthic ecosystems.

Trawler vessels vary in size, from small artisanal fishing boats to large factory ships that process the catch on board. In Brazil, the trawl fleet is significant in the South and Southeast regions, where shrimp and demersal fish fishing are traditional. Regulatory agencies like IBAMA set catch limits and closed seasons to try to ensure sustainability.

Despite controversies, trawlers remain a vital tool for global food security, providing low-cost animal protein. Technological innovations, such as selective nets and electronic monitoring, aim to reduce bycatch and habitat damage. The use of authentic film grain images helps document the reality of working at sea, with an aesthetic reminiscent of historical fishing records.

Frequently Asked Questions

What is a fishing trawler?

A fishing trawler is a vessel equipped to drag trawl nets through the water, capturing large quantities of fish or shellfish at once, primarily used in industrial fishing.

What are the environmental impacts of trawling?

Trawling can damage the seabed, destroy benthic habitats, and capture non-target species (bycatch). Selective nets and exclusion zones are among the measures used to reduce these effects.

Where is trawling most common in Brazil?

Trawling is common in the South and Southeast regions of Brazil, especially for shrimp and demersal fish, with fleets operating in states like Santa Catarina, Rio Grande do Sul, and São Paulo.
