Zooplankton abundance, community composition, and developmental stages of individual species of zooplankton were monitored at two locations in Breiðafjörður, West Iceland, every 10 days in the summers of 2008–2009. In addition, egg production and gut content were measured for the two most abundant species of copepods, Temora longicornis and Calanus finmarchicus. The abundance of females of T. longicornis varied between years with annual mean abundance of 31 000 females m–2 in 2008 and 300 females m–2 in 2009. Annual mean abundance of C. finmarchicus was 6000 females m–2 and 3000 females m–2 in 2008 and 2009, respectively. Feeding of copepods was estimated based on gut content, quantified as chlorophyll a. The gut content of T. longicornis ...
