Edwardsiella tarda was isolated from 47, 88, and 79% of skin, visceral, and dressed-fish samples, respectively. This species was also isolated from 30% of imported dressed fish, 75% of catfish pond water samples, 64% of catfish pond mud samples, and 100% of frogs, turtles, and crayfish from catfish ponds. The incidence of Edwardsiella increased during the summer months, as water temperatures in...

Several external and internal factors contribute to the reproductive success of teleosts, which makes process complex unique. In Indian freshwater catfish, Heteropneustes fossilis, monsoon plays a crucial role as it fine tunes neuroendocrine axis, culminating in oocyte maturation. Therefore, induction maturation requires coordinated interaction among hypothalamic, hypophyseal, peripheral hormon...

Methods: A total of 69 samples from freshwater, marine, and anadromous fish were collected randomly from fish farms and retail stores in Stara Zagora region, Bulga...

Large-scale habitat preferences of riverine taxa are not always revealed by examining community data. Here, we show how lipid and growth can be used to evaluate hydrologic habitat preferences of fishes resilient to river fragmentation (i.e. species that can tolerate river fragmentation by dams, but not collapse). Lipid content was examined for seven fishes in a major southeastern USA reservoir ...
