Rapport fra høstundersøkelsene med strandnot i Indre Oslofjord 2014

Abstract

This report gives a short summary of the basic findings on some key species sampled in the beach seine survey in the inner Oslofjord in 2014. The beach seine survey has been conducted in its present form since 1919. Cod recruitment in the area in 2014 was low even compared to the historical low trend the most recent years. No recruits of cod were found in the Inner Oslofjord and neither was there any adult cod. A general impression is that warmer water species have had an increase the last 20 years. There also seems to be an increase in pelagic species at the cost of some benthic species
