Based on life history and ecological characteristics, several authors have placed seamount fishes at the extreme end of the vulnerability spectrum. However, it was still unclear if there is justification for the generalization that seamount fishes overall possess specific life-history characteristics that render them more vulnerable to fishing than other species. In this contribution, we test t...

Fewer than 200 fish species are found in freshwater habitats in Australia, of which 144 are confined exclusively to freshwater. At least 22 species of exotic freshwater fish have been introduced into Australia, and 19 of these have established selfsustaining populations. However, the parasite fauna of both native and exotic freshwater fishes in Australia is poorly known. This is particularly th...

We correlated maximum lengths of freshwater fishes captured during 10 years with standard gears (i.e., gill nets, boat electrofishers and trap nets) and angling from Nebraska water bodies to determine which methodology provided better estimates of maximum size of fishes produced within a given water body. In general, maximum length of fishes captured with standard gears was smaller than maximum...

Introduction Seafoods are inherently functional and possess many components that are good for human health. Seafoods and their by-products are an excellent source of nutraceuticals and bioactives, and these can be extracted/isolated and added to a range of foods thereby enhancing functionality of the foods in terms of human health (Shahidi, 2003; Alasalvar and Taylor, 2002). These aspects are a...

Most members of the genus Calaxias are small to mediumsized, fast-swimming, mid-water fishes that can be either lacustrine or diadromous (Whitley 1935). However, one species, Calaxias cleaveri Scott 1934, differs so markedly from typical Tasmanian members of the genus that at one stage it was referred to tpe genus Saxilaga by Scott (1936). Meristic and morphometric comparison of the mainland Ta...

Large-bodied reef fishes represent an economically and ecologically important segment of the coral reef fish assemblage. Many of these individuals supply the bulk of the reproductive output for their population and have a disproportionate effect on their environment (e.g. as apex predators or bioeroding herbivores). Large-bodied reef fishes also tend to be at greatest risk of overfishing, and t...

the native fishes of springs, ghanats and caves of iran are uniquely significant, since they are rear and, because of pollution, dryness, . purposeful or accidental introduction of exotic species and over all, because of industrialization are in danger. the stock of valuable fishes of iran are declining while they have not been completely identified. the stock of these fishes, particularly thos...

the analysis of net catches made in absheron gulfs of the caspian sea during 2011-2012 is provided. the ichthyofauna of absheron gulfs, including 26 species found in the north gulf, and 33 species and subspecies found in the south gulf was studied for the first time. a taxonomical and ecological diversity of the fish fauna of north and south absheron gulfs is characterized. the peculiarities of...

Populations of reef fish are widely believed to be limited by availability of larval recruits, not by density dependent processes operating during and after settlement of young stages in the reef environment. Our research explores and challenges this thinking. We are utilizing field observations and experiments to determine what factors affect spatial distribution, abundance, and population dyn...

the gobies are non-commercial fishes in the iranian waters of the caspian sea for which population dynamics and stock status are poorly known. in this survey, we tried to define species diversity and catch per unit effort (cpue) of gobiidae by using beach seine nets in salmanshahr, the southern caspian sea. from march 2011 to april 2012, 224 specimens representing 4 gobiid species, belonging to...
