OTTER TRAWLER Meaning and
Definition
-
An otter trawler is a specialized type of fishing vessel that is primarily used for commercial fishing activities, specifically for trawling. Trawling is a fishing method in which a large fishing net, called a trawl, is towed behind the vessel to capture fish and other aquatic organisms.
The unique feature of an otter trawler is the use of otter boards, which are large, square-shaped wooden or metal boards attached to either side of the net. These boards help to spread the mouth of the net open horizontally by creating drag in the water. This design enables the net to cover a wider area and ensures that it remains open as it is being towed, maximizing the catch potential.
Typically, otter trawlers are equipped with a powerful engine and advanced navigation systems to facilitate efficient fishing operations. They may also have onboard facilities for processing and storing the caught fish onboard, such as refrigeration systems or freezing compartments.
Otter trawlers are commonly used in commercial fishing industries, especially for deep-sea fishing, where pelagic or demersal fish species are targeted. They are often operated by a crew of skilled fishermen who are responsible for deploying and retrieving the trawl net, as well as sorting and storing the catch.
Despite being an effective fishing method, there are concerns about the environmental impact of otter trawling, as the heavy nets and otter boards can disrupt and damage the seafloor habitat. Efforts are being made to develop more sustainable fishing practices and reduce the negative ecological consequences associated with otter trawling.
Etymology of OTTER TRAWLER
The word "otter trawler" is a combination of two terms: "otter" and "trawler".
The term "otter" refers to a type of large fishing net that is used to catch fish. It is known as an "otter board" or "otter trawl" because the net is attached to boards or doors on either side. These doors help to spread the net open in the water, making it more effective in catching fish.
The term "trawler" originally referred to a type of fishing boat or vessel that is equipped with a trawl net. A trawl net is a large, funnel-shaped net that is dragged along the bottom of the sea or lake to catch fish or other marine species.
