Identification of Clupeiformes early life history and its distribution on Bushehr Waters of Persian Gulf

The fisheries management requires the knowing of spatial and temporal spawning fish and identifies their early life history. Samplings have been done in Bushehr coastal waters: Nayband Bay (1998), Central creek of Bushehr (1999), Southern coastal Bushehr waters (2000), Northern coastal Bushehr waters (2002) and Khark & kharko Islands (2008) by Bongo-Net plankton sampler with 500µ mesh size. Two families Clupeidae and Engraulididae were identified and some genera also introduced that were included: Sardinella (body very elongate, whiteout teeth in early life period) Dussumieria (with large teeth), Ilisha (without teeth with fewer meyomer), Encrasicholina (the posterior 2-7 base of the dorsal fin lie posterior to the anus) and Thryssa (the dorsal fin is entirely anterior to the anus and the anal fin longer than the dorsal fin) genera were found. The highest abundance of this order was in spring in all research.
