    • Effects of season, bottom substrate and population dynamics on fish communities in shallow subarctic northeast Atlantic waters 

      Sørensen, Ole Johannes Ringnander; Pedersen, Torstein (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-28)
      ish communities in the shallow waters (9–20 m depth) of outer Malangen (69o N), Northern Norway was studied to investigate effects of season, bottom substrate associations and population dynamic parameters on the fish assemblages. In four fieldtrips during one year at four locations, fish were sampled by trammel nets and bottom substrate composition was monitored by underwater video. A total of ...

    • Fish communities in shallow coastal waters - a study of effects of season and bottom substrate 

      Sørensen, Ole Johannes Ringnander (Master thesis; Mastergradsoppgave, 2019-05-13)
      Fish communities in the outer part of Malangen fjord, Troms county were studied to identify seasonal and spatial variation. The fish species compositions differed between seasons and at the four different locations. Cod (Gadus morhua L.) dominated the trammel net catches at all months except in March, in which plaice and other flatfishes were the most numerous. Species richness and diversity were ...
