Description:
Occurrence and distribution of larval and juvenile fish was investigated in nearshore
waters of the southeastern Caspian Sea including the Gorgan Bay. Samples were
collected during seven surveys using a fine mesh beach-seine in five sampling sites
from July 2014 to June 2015. A total of 15500 individuals mostly juvenile were
captured, representing 18 species from 8 families. Most juveniles belonged to Liza
saliens, Atherina caspia, Neogobius pallasi and Neogobius melanostomus. The
juveniles of Alburnus chalcoides, Vimba persa, Syngnathus caspius and gobies
Neogobius caspius and Ponticola syrman occurred in low number (relative abundance
0.1% - 9.3%). Highest number of juveniles were caught in summer season. The
occurrence of larval fish in coastal waters of southern Caspian was recorded for the first
time (Atherina caspia with minimum length of 12 mm in Caspian and 9.5 mm in
Gorgan Bay). In spring, early juveniles of mullet, Liza aurata, increased in the Caspian
sites but they moved up to deeper waters by the end of the season. Based on results, the
density of juvenile fish (specially Liza saliens) in Gorgan Bay was several times more
than Caspian sites so it could be considered an important nursery ground in the region
