this study was conducted to determine taxonomic feature of fishes from the headwaters of three riverine systems in kohgiluyeh and boyer-ahmad province (k & b) in southwestern iran during 2011 to 2013. fifteen species belonging to 4 families, and 3 orders from the karun river system, 10 species belonging to 4 families and 3 orders from the zohreh river system and 8 species belonging to 2 fam...

A total of 154 samples of marine (n=51) and freshwater fish (n=103) were obtained from fish markets in Elazig Province of eastern Turkey. These samples were tested for Campylobacter, Listeria and Salmonella using culturing and biochemical methods. Campylobacter failed to be detected in any freshwater or marine fish samples. Listeria was detected in 22 and 14 of gill and skin samples from freshw...

pattern of feeding and reproduction of amblypharyngodon mola (hamilton, 1822) was studied in two floodplain lakes of north 24 parganas districts of west bengal in india during 2011.  results indicated that the fish exhibited a predominantly herbivorous diet with algae as the main content of gut. a long, thin walled, coiled gut and closely packed filamentous gill racker suited this feeding habit...

freshwater fish biodiversity is a precious natural asset in terms of economic, cultural and scientific interest. and yet, the inland freshwater ecosystem in malaysia is declining at a far greater rate than terrestrial ecosystems in the tropics. what happened, and what is being done to address the crisis? this paper extracts findings from the latest literature and explores overarching issues per...

present survey synthesized information on fish biodiversity in the perennial freshwater body of ramnagar, east midnapore district of west bengal, india. we documented 45 fish species under 29 genera, 18 families and 8 orders during the periods from1990 to 1995, whereas, 34 species from 21 genera and 12 families under 7 orders were recorded presently from freshwater body of different perennial p...

the lernaea parasite was reported in alburnus hohenackeri kessler, 1870, collected from the char-nimeh (or chahnimeh) lake, eastern iran. three fishes were infected with l. intestinalis having 3 to 22 parasites increasing with fish size. the maximum and minimum of parasite lengths were 138.02 mm and 24.54 mm respectively. the prevalence, mean intensity and abundance of infection by plerocercoid...

The author performed a retrospective study on 5 complete reports with geographical data and the prevalence of metacercariae in Thailand. The relation between rainfall (derived from the geographical data) and the prevalence of metacercariae in freshwater fish (derived from the overall infection rate of metacercaria) was investigated. The least- square equation plot rainfall (y) versus prevalence...

Pigment pattern variation across species or populations offers a tractable framework in which to investigate the evolution of development. Juvenile threespine sticklebacks (Gasterosteus aculeatus) from marine and freshwater environments exhibit divergent pigment patterns that are associated with ecological differences. Juvenile marine sticklebacks have a silvery appearance, whereas sticklebacks...
