Zooplankton - Kola section

E-mail Print PDF

C. finmarchicus was a dominant species among copepods on the Kola section, which is located further east of the Fugløya-Bear Island (FB) transect. Comparison of C. finmarchicus abundance and life stage structure are here studied in two relatively warm years (1983, 1992) and in an abnormally warm year (2008, Figure 4.3.12, Russian data). The results for 2008 showed that all C. finmarchicus stages, including nauplii and young copepodites, were more abundant this year along the whole section than in 1992 and in particular for 1983 (Figure 4.3.12).

A quite new feature in 2008 was that young specimens of C. finmarchicus in stage CIV and CV were found also in deeper waters. The relatively high abundance of nauplii and young copepodites in 2008, in particular compared to 1983 has obviously provided favourable feeding conditions for relevant fish larvae (Karamushko and Karamushko, 1995).
