R/V Hålabben

R/V Hålabben is a modern, small high-speed research vessel designed for fish surveys, as well as bottom and water sampling. The boat is equipped for trawling, fish sorting and echo integration of fish. Hålabben is also equipped with winches for smaller sampling operations over the side.

Hålabben's area of operation is inshore with a maximum distance from the outermost islands of 1 nautical mile or 4 nautical miles from the nearest safe harbor. The boat can be transported by truck to different sea areas and lakes.

Basic data

  • Length: 7.85 meters
  • Width: 3.00 meters
  • Depth: 0.45 meters
  • Cruising speed: 24 knots
  • Minimum height: 3.6 meters (when in transport)

Primary assignments

  • Echo integration at night (primarily Gadidae)
  • Inshore trawling
  • Exploratory lobster fishing
  • Fish surveys with traps
  • Ocean current surveys
  • Has been used to catch lobster larvae with light traps

Reseach vessel R/V Hålabben


Elritsan is an electric fishing boat, Smith Root SR 18E, with a "beard" in the prow and two long "antennas" protruding from the prow down into the water. When the electric current is switched on an area of tension is created between the "beard" (cathode) and the "antennas" (anode). The fish is stunned, floats to the surface, is caught with a dip net and placed in a water filled tank to recover, which it does in about a minute. After determining species, measuring and sampling the fishes are released back into the water alive.

The electric fishing boat works excellently to catch fish in large streams and lakes, and it provides an opportunity to examine waters and environments that would otherwise be difficult to survey.


Klabben is a shallow-draught catamaran with an inboard motor and a small cabin. Klabben is primarily used for sampling, trap fishing and scientific fish collection on the Swedish west coast.

There is a number of smaller boats at the Institute of Freshwater Research and the Institute of Coastal Research.
