Agunmukha River is an important water body having plentiful aquatic resources. The fisheries communities in the river are familiar with a diverse range of fishing gear and crafts to catch fish. Therefore, the objectives of the present study were to explore fishing gear and fishing crafts, catch composition of the respective gearand identification of fish biodiversity of Agunmukha River. A step ...

various human pressures are affecting the aquatic biocoenosis in running waters of iran - similar to many other areas of the world. overall 190 sites, 88 at salmonid (44 reference/impacted respectively) and 102 at cyprinid (50 reference/52 impacted) streams of the southern caspian sea basin were investigated in terms of human pressures present and the related impact on fish assemblages. in tota...

abstract in this study, big-head carp flesh was processed and fish finger was produced by the formula of 1, 2 and 3 with 70, 80 and 93.5 percent of big head fish flesh respectively. then sensory attributes, biochemical changes and nutritional value such as peroxide value (pv), thiobarbituric acid (tba) and the total volatile nitrogen (tvb-n) changes and microbial load of all three formulas were...

In this study, changes in some quality parameters of fish chips produced from sand smelt (Atherina boyeri, RISSO 1810) during storage period (at -18  o C for 6 months) were determined.  The difference between the amount of moisture, crude protein, crude fat and crude ash components of raw fish in fish chips was significant (P<0.05). Pre-frying  process resulted in a decrease in all fatty acid c...

in this investigation, the mercury content of different samples of persian gulf shrimp and fish, caspian sea fish and the samples of fish from bandar pahlavi lagoon, zarjoub river near rasht, zayandehroud river near esfahan, and karadj river near tehran were measured by flameless atomic absorption, cold vapor-technique, using standard addition method. the main purpose of this study was to inves...

The Shiner Perch (Cymatogaster aggregata Gibbons) exhibits a viviparous reproductive mode and long-term female sperm storage, two biological features that may predispose this fish species for both intense sperm competition and frequent multiple paternity within broods. To test these hypotheses, we used polymorphic microsatellite markers to identify sires and quantify paternal contributions to t...

Modifications to stream hydrologic regimes can have a profound influence on the dynamics of their fish populations. Using hierarchical linear models, we examined the relations between flow regime and young-of-year fish density using fish sampling and discharge data from three different warmwater streams in Illinois, Alabama, and Georgia. We used an information theoretic approach to evaluate the...
