Ornamental fish keeping has become an increasingly popular hobby, and there are now more than 330 mil lion ornamental fish sold each year throughout the world (Riehl and Baensch 1989). Although the total number of fish species exceeds 30,000 (Friede 1987), only 4000 of these species classify as freshwater or namental species (Riehl and Baensch 1989). Of these species a few hundred are popular a...

A study was conducted to determine the growth performance and bioaccumulation and tolerance of metal mixture toxins in five fish species including Labeo rohita, Catla catla, Cirrhina mrigala, Hypophthalmichthys molitrix and Ctenopharyngodon idella separately, under chronic exposure of metal mixture (Fe + Zn + Pb) at sub-lethal concentrations (1/3 of LC50) for 12 weeks period. Moreover, response...

This study aimed to investigate the chemical composition and amino acid (AA) profile of seven freshwater fish species representing two mean live-weights inhabiting River Indus. For this purpose chemical composition was analysed by standard methods and amino acids were determined with an amino acid analyser (Biochrom-30 ion-exchange analyser). The fish species and live-weights differed significa...

In this study, the concentration levels of the probable carcinogenic PAH fractions, benzo[a]pyrene (BaP) and benzo[k]fluoranthrene (BkF) in fillets of some processed fish species were investigated. Fish species comprising Merluccius poli (hake), Tyrsites atun (snoek), Seriola lalandi (yellow-tail) and Brama brama (angel fish) were bought in fish shops at Gordon's Bay, Western Cape, South Africa...

The quantification of abundance, size, and distribution of fish is critical to properly manage and protect marine ecosystems and regulate marine fisheries. Currently, fish surveys are conducted using fish tagging, scientific diving, and/or capture and release methods (i.e., net trawls), methods that are both costly and time consuming. Therefore, providing an automated way to conduct fish survey...

in the present investigation a total of six parasite species, some eye-specific and others non-organ specific parasites were found in the eyes of 48 examined fish species, collected from fresh and brackish waters of iran during 2004-2006. ichthyophthirius multifiliis  was isolated from the external surface of the eyes of oncorhynchus mykiss, gyrodactylus stankovici from cyprinus carpio and lern...

World aquaculture production is dominated by omnivorous fish species that live in freshwater, including various carp and catfish species. Soybean meal is a prominent ingredient used in prepared diets for these species, often constituting 50 to 60% of the total formulation. Such levels of incorporation are possible due to adequate palatability of soybean meal and its excellent nutritional value ...

BACKGROUND Estimates of exposure to toxicants are predominantly obtained from single time-point data. Fish consumption guidance based on these data may be incomplete, as recommendations are unlikely to consider impact from factors such as intraindividual variability, seasonal differences in consumption behavior, and species consumed. OBJECTIVES/METHODS We studied populations of Korean (n = 10...
