Bottom Trawl Fishing Net Diagram - Marine Harvesting Equipment Explained #3694580 (License: Personal Use)

This black-and-white technical drawing depicts a traditional bottom trawl fishing system deployed in shallow coastal waters, with two net panels (1) suspended between surface floats (2) and anchored to the seabed via weighted lines (3) and anchors (4). The net is designed to sweep the ocean floor to capture demersal fish species, and the labeled components illustrate key structural elements for stability and operation. Mountainous terrain in the background suggests a fjord or sheltered bay environment typical for such fisheries.

Used in marine biology, fisheries science, and aquaculture education resources; commonly appears in textbooks, government fishery reports, or environmental impact assessments to explain gear configuration and ecological implications of bottom trawling.
