Seven species of fishes, 6 species of mollusks, 1 species of crab, and 1 species of shrimp were collected from 12 natural freshwater sites from 5 provinces: Lumpang, Phrae, Phayao, Chiang Rai and Chiang Mai during the Rainy season of 2000. Fishes, Channa striatus, Dermogenus pusillus, Oxyeleotris marmoratus, Trichogaster trichopterus and Trichopsis vittatus were examined for helminths and 34.69...

a survey on endo-parasitic infections on barboid fishes of south- west of iran (khouzestan province) was carried out from spring 2007 to atumn 2009. altogether 296 specimens from five different fish species were examined, they are barbus grypus heckel, 1843; barbus sharpeyi günther, 1874; barbus esocinus heckel, 1843; barbus barbulus heckel, 1849 and barbus pectoralis heckel 1843. the fishes we...

this study conducted to provide the status of parasite communities of four sturgeon species viz. acipenser stellatus , a. gueldenstaedtii , a. nudiventris , and huso huso in the southwest of the caspian sea and their histopathological effects on the examined fishes. for this purpose a total of 93 individuals of four sturgeon species were caught in two fisheries regions from the southwest of the...

The genus Alburnoides Jeitteles, 1861 in Iran is reviewed, and diagnoses are presented for all eight recognized species. Alburnoides eichwaldii, A. holciki, A. idignensis, A. namaki, A. nicolausi, A. petrubanarescui, A. qanati and A. tabarestanensis are considered valid and three new species are described: Alburnoides coadi sp. n., from Namrud River in Kavir basin, A. parhami sp. n., from Atrak...

Accurate estimates of reproductive parameters important in understanding life history evolution and conservation small fishes are dependent upon careful assignment ovarian phases. Proper is based the stages propagule (oocyte) development, oocyte maturation location any clutch or portion thereof within ovaries. Macroscopic inspection developmental phases have often been used for freshwater fishe...

Physiological studies of larval fishes have lagged far behind those of adults, yet offer tremendous opportunities for expanding our knowledge of the basic biology of both marine and freshwater fishes. Physiological studies of larval fishes can also improve research and management in areas of applied science, such as aquaculture, fisheries, and environmental assessment. Additionally, larval fish...
