The efficiency of breeding schemes is dependent on the high fecundity of the selected individuals. Reproductive technologies are constantly pushing the physiological limits, but while the male reproductive potential is almost fully exploited, female reproductive physiology is the subject of constant research. Since the number of offspring that a female can bring to term each pregnancy cannot be...

It is predicted that Japan and European Union will soon experience appreciable decreases in their populations due to persistently low total fertility rates (TFR) below replacement level (2.1 child per woman). In the United States, where TFR has also declined, there are ethnic differences. Caucasians have rates below replacement, while TFRs among African-Americans and Hispanics are higher. We re...

Abstract The endocrine-disrupting effects of triclosan, an antimicrobial agent, and its involvement in reproductive responses mediated through different modes activity various fish species have been documented. present study aims to explore whether triclosan at environmentally relevant sublethal concentrations could influence the physiology Anabas testudineus spawning phase. Fish were exposed (...
