Pathogenicity of viral nervous necrosis virus for Guppy fish, Poecilia reticulata
The pathogenicity of a Nervous Necrosis Virus isolate obtained from naturally infected Golden grey mullet (Liza auratus) suffering serious mortalities in Iranian coastline water of the Caspian Sea was investigated for first time. An experimental infection has been performed using three groups, two experimental groups and one control group of Guppy (Poecilia reticulata) with mean weight 0.47±0.0...

متن کاملStrategies for Nile Tilapia (oreochromis Niloticus) Pond Culture
Different strategies for Nile tilapia (Oreochromis niloticus) culture in ponds with a series of progressive inputs were compared. The sequential experimental stages to increase fish production through intensification were: 1) triple superphosphate (TSP) only; 2) chicken manure only; 3) chicken manure supplemented with urea or urea and TSP; 4) urea and TSP; 5) continually supplemental feeding; 6...
متن کاملFiltration Rates of Catfish Pond Phytoplankton by Nile Tilapia Oreochromis niloticus
Filter-feeding fishes have been examined as biological controls of phytoplankton populations. Although increased phytoplankton biomass resulted in approximately 50% of studies and no effect in 25% (Smith 1988), changes in species composition and dominance have been noted. For example, blue tilapia Oreochromis aureus reduce or eliminated blue-green (Cyanobacteria) and green (Chlorophyta) net phy...
متن کاملAn overview of Betanodavirus and perspective of Viral Nervous Necrosis (VNN) disease in Iranian southern waters
The Persian Gulf and its shores are important and strategic areas with a large variety of fish species. Betanodavirus infection is known to be a serious threat to susceptible fish and causing economic damages to the fisheries and fishing industry. Concerning to isolation and confirmation of VNN virus in the Mullet fish (Chelon aurata and C. saliens) in the Caspian Sea and its damages on Mullet ...
