some parasites can be transferred from fish to human via eating of contaminated meat and make serious problems in consumers. in the present study zoonotic parasites of abdominal cavity in pike-perch, sander lucioperca, in south eastern part of the caspian sea have been surveyed. in this regard, 30 fish were caught by purse seine net and abdominal cavity, digestive tract and other organs (kidney...

The walleye population in Canadarago Lake, New York, was 81-95% exploited in the 1988 fishing season, the year in which a previous restriction on the length and number of legally harvestable fish was liberalized. Using diary records from a subset of fishermen, growth estimates, and an estimate of the walleye population in the following year, a method is developed to reconstruct the fish populat...

An association between acidification of lakes and high mercury concentrations in fishes has been reported. In northern Wisconsin (USA), for example, walleye (Stizostedion vitreum) in naturally acidic lakes have higher mercury concentrations than walleye in circumneutral lakes (Weiner, 1983). In this study a bioenergetic based model for mercury uptake is applied to identify potential causes of h...

the systematics, morphology, distribution, biology, economic importance and conservation of the perches of iran are described, the species are illustrated, and a bibliography on these fishes in iran is provided. there are three species, perca fluviatilis , sander lucioperca and s. marinus , found naturally in the caspian sea basin, with s. lucioperca translocated.

A class of nonconforming quadrilateral membrane elements, introduced by Sander and Beckers, is discussed in all details. It is proved that two elements that do not pass the patch test may still yield convergence under a suitable condition on mesh subdivisions, whereas one such element is found to be divergent for all mesh subdivisions. All other finite elements in this class that pass the patch...
