Feeding strategies of threeNeogobiusspecies in the Gomishan Wetland of Iran, South-east Caspian Sea

Feeding strategy of the Deepwater Goby,Chasar bathybius, in the Southern Caspian Sea (Osteichthyes: Gobiidae)

“…The main diet component of Neogobius fluviatilis in more marine, brackish and riverine habitats was chironomid larvae (see Pinchuk et al, 2003 for review;Adamek, Andreji, & Gallardo, 2007;Grabowska, Grabowski. & Kostecka, 2009;Abdoli et al, 2012) and it was a mollusc consumer in some habitats (see for review). Molluscs, chironomids and amphipods were the prey items most heavily consumed by Neogobius melanostomus (Ray & Corkum, 1997;French & Jude, 2001;Diggins, Kaur, Chakraborti, & DePinto, 2002;Barton, Johnson, Campbell, Petruniak, & Patterson, 2005;Adamek et al, 2007;Abdoli et al, 2012).…”

In larger round gobies, molluscs (mainly dreissenids) have been identified as the preferred prey (Ray & Corkum, 1997;Barton et al, 2005).…”

“…It inhabits sandy and shelly bottoms and, in smaller numbers, firm silt down to 75 m (Miller, 2003). The gobies play an important role in the general production of the Caspian Sea because of their species abundance (Abdoli, Allahyari, Patimar, & Kiabi, 2012). Gaibova and Ragimov (1970) found that in coastal waters of the western shores of the Caspian Sea larger specimens of C. bathybius feed mainly on fish, while smaller individuals feed on crustaceans.…”
