Seismic activity both increased and reduced fish catches

The sound produced by a seismic survey increased catches for some species and reduced them for others. It appears that saithe may have partially migrated out of the area, whilst other species apparently stayed. These are the main findings of the Institute of Marine Research's summer 2009 investigation into the impact of seismic activities off Vesterålen, a project commissioned by the Norwegian Petroleum Directorate.

Searching for viruses along the coast

This week, the research vessel “Håkon Mosby” completed a cruise along the Norwegian coast from Stad to Trøndelag. Scientists from the Institute of Marine Research, and the National Veterinary institute sampled fish which are to be further analyzed for the presence of VHS-virus. This virus can cause high mortality, both in wild and cultured fish populations.

In focus: Northeast arctic cod

Cod is a predatory fish and mainly a demersal fish, but in the Barents Sea it is also to a large extent distributed in the pelagic water masses during some parts of the year. Young cod (age 0-2) feed mainly on zooplankton, while fish and benthic organisms are the main food items for the older cod.

Vesterålen/Lofoten are the main spawning areas for cod. The eggs are spawned pelagically in February-April. Egg and larvae are carried with the current into the Barents Sea, and the 0-group fish settles to the bottom there in late autumn.
