Abstract

Caspian Kutum (Rutilus frisii kutum, Kamensky 1901) is among the main commercial species in the
Caspian Sea. The present study aimed to determine the spatial and temporal distribution patterns of
Kutum in depth ranges of 10 to 100 m by bottom trawl net in Iranian waters of the Caspian Sea
during 2008 to 2010. The results showed that the maximum catch and CPUE were 2903 kg and
57.08 kg/0.5 h in winter 2009. The minimum catch and CPUE were 79 kg and 1.41 kg/0.5 h in
spring 2010. During the warm seasons (spring and summer) most Kutums occurred in depths less
than 20 m. While, during cold seasons they occurred at all depths. The average (±SE) CPUE was
94.0 ± 78.53 kg/0.5 h in depths 20-50 m in autumn and 128.3 ± 77.64 kg/0.5 h in depths >50 m in
winter.
