TitleSerrivomer beani Gill & Ryder, 1884 (Pisces, Anguilliformes, Serrivomeridae): some aspects of seasonal variation in numbers and distribution in the mid North Atlantic
JournalBijdragen tot de Dierkunde
AbstractIn Rectangular Midwater Trawl samples taken along the 30°W meridian in the mid North Atlantic, Serrivomer beani reaches its greatest density in April-June between 25° and 34°N. In this period the larvae of this species are caught here as well.
There is a significant increase in size of the individuals from 24° to 55°N. In October samples along the same meridian, S. beani was caught from 24° to 40°N only. Because the net used is not effective in collecting size classes above about 300 mm, it is presumed that north of 40°N S. beani is present, but consists of larger individuals.
No evidence is found that S. beani undertakes diurnal vertical migration.
