Trawl Dredge
overall review score: 3.2
⭐⭐⭐⭐
score is between 0 and 5
A trawl-dredge is a type of fishing gear used in commercial fishing operations to harvest benthic (bottom-dwelling) species. It combines a trawl net, which is dragged through the water column, with a dredge, typically a heavy metal frame or basket with openings that is dragged along the sea floor to collect shellfish such as scallops, clams, or oysters. This method allows for efficient harvesting of species that live on or near the seabed.
Key Features
- Combination of trawl netting and dredging equipment
- Designed for bottom-feeding species like scallops and clams
- Heavy-duty construction to withstand seabed conditions
- Operated using specialized vessels with precise navigation systems
- Variety of dredge types tailored to target specific species and seabed terrains
Pros
- Highly efficient for harvesting benthic shellfish
- Allows large-scale commercial production
- Can access species that are otherwise difficult to harvest
Cons
- Can cause significant environmental damage to ocean floors
- May result in bycatch and habitat disruption
- Regulatory restrictions due to ecological impact concerns
- Potential for overfishing of target species
