The Salton Sea is the largest inland body of water in California. It currently supports a sportfishery for orangemouth corvina (Cvnoscion xanthulus). Other species of importance are the bairdiella (Bairdiella icistius) and sargo (Anisotremus davidsonii). The future status of the fishery is uncertain for several reasons including possible impacts from chemical contaminants entering the Sea via a...

landmark based geometric morphometrics and comparison of meristic characters was used to understand potential differences between populations of waspi in mashkil and mokran basins. 97 specimens of waspies were caught (64 from mashkil river and 33 from sarbaz river). 14 landmarks were digitized on pictures taken from left side of specimens and meristic characters were counted. data were analyzed...

During a parasitological investigation on the fresh water fishes of North West of Iran (West Azerbaijan Province), 266 specimens of 11 fishes were examined. Fishes were collected from seven stations from Aras, Zangbar and Sarysou Rivers between summer 2001 to summer 2002. Nine protozoan species were detected; eight Cilliophora and one Rhizopoda. Cilliophora are: Chilodonella sp., Apiosoma sp.,V...

In this Focus article, the authors ask a seemingly simple question: Are harmful algal blooms (HABs) becoming the greatest inland water quality threat to public health and aquatic ecosystems? When HAB events require restrictions on fisheries, recreation, and drinking water uses of inland water bodies significant economic consequences result. Unfortunately, the magnitude, frequency, and duration ...

The reported annual yield from inland capture fisheries in 2008 was over 10 million tonnes, although real catches are probably considerably higher than this. Inland fisheries are extremely complex, and in many cases poorly understood. The numerous water bodies and small rivers are inhabited by a wide range of species and several types of fisher community with diversified livelihood strategies f...

Aeromonas spp. are oxidase positive, gram-negative, facultative anaerobic bacilli that are widely distributed in aquatic environments. A.hydrophila, A.sobria and A.bestiarum may cause severe infections in both human and cold-blooded animals. Environmental persistance of quinolones that are widely used in both human and veterinary medicine plays an important role in the selection of resistant mu...

background: iron, manganese, and aluminum are three abundant metals on earth and their concentrations have increased in aquatic environments as a result of natural and industrial activities. this study was undertaken to report the median acute toxicity (lc50) and accumulation of the sub-lethal concentration (10% 96-h lc50) of iron (fe), manganese (mn) and aluminum (al) in kutum (rutilus kutum) ...
