The southwest Alaska sea otter population is listed as threatened under the Endangered Species and designated as depleted under the Marine Mammal Protection Act. Threats Competition with commercial shellfish fisheries, entanglement in commercial fishing gear, oil spills, disease outbreaks, contaminants, subsistence harvests, killer whale predation. English examples for "otter-trawl" - It will be noted that the number of otter-trawl fares from this ground is small. In the otter-trawl catch from this ground it will be noted that the positions of the two species are reversed. The proportion of cod taken here by these vessels is very small, even smaller than that from other grounds fished by the otter-trawl method.
The otter trawl was introduced into New England in when the vessel Spray was so successful that in the next few years other vessels became otter trawlers. Like the European trawlers, the New England vessels were large steamers which landed the net along side (usually starboard) by the use of a fore gallows and a similar one aft. The sea otter is very different from the other otters since it spends the majority of its time in salt water and is perfectly content to float around the kelp beds. A sea otter has underfur and the guard hair, the finest of any mammal, consisting of , to 1 million hairs per square inch. These hair fibers connect to trap air between them.
An icon of the California coast, the Sea Otter is an aquatic member of the weasel family, found along the coasts of the Pacific Ocean in North America and Asia. The average adult can be as large as m (about 5 feet) long and weigh up to 45 kg (about 90 pounds). The WAScoOT3 begins in and ends in , Moriarty et al () detail the survey’s history. The Wider Atlantic Scottish Quarter 3 Otter Trawl Groundfish Survey Monitoring and Assessment Data resource contains both biological and sampling information.

A fishing trawler is a commercial fishing vessel designed to operate fishing ng is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers.

A trawler may also operate two or more trawl nets simultaneously (double-rig. outrigger trawlers towing one or two trawls from outriggers on both sides. Trawls towed from each outrigger are spread horizontally with two otter boards on each side. Vessel Class Length normally > 10 (Actualmetres) Tonnage normally > 5 (Gross in register tons) Deck Arrangement The superstructure can be placed in the forward part, amidships or aft.
otter twin trawling, two identical trawls are towed side by side, there will be in addition to a pair of otter boards, a sledge between the two nets).There are many models of otter boards: they may be relatively heavy, made of wood, aluminium and steel or a combination of these, rectangular or oval shaped and equipped with a steel sole designed for good contact with the ground.
The Scarborough trawler OTTER arrived in port on Saturday with a seamen named Fielding, of Goole, mate of the hopper RUNSWICK which sunk in the North Sea.
The hopper, laden with grain, was being towed by the tug GEORGE PEABODY, but had to be cast adrift owing to the heavy gale.
