Sammendrag
In an attempt to collect adequate samples of cod and other
larvae in the spawning areas off SW-Iceland, experiments using
a large fish pump for this purpose were carried out from 1981
to 1983. The pump used was an 8" hydraulic centrifugal pump
commonly used by fishing vessels in Iceland.
In 1981 samples were taken at a fixed station off Reykjanes
at 6-8 depths from 0 to 34 m at 4 h intervals for 36 h. In 1982
and 1983 vertical profiles were taken at various stations.
From the samples valuable information on the larvae and
their distribution and feeding was obtaind.
It is concluded that the development of a convenient pumping
system has been quite successful. The main limitations of the
system is that sampling would be rather time consuming in areas
of low larval density. For the present studies it does not
mattet but this could be limiting in studies in coming years of
other areas at Iceland with less spawning.
