Generational Effects of Bisphenol A on Growth and Stress Performance in Rainbow Trout

The aquatic environment is severely impacted by xenobiotics that are released due to anthropogenic activities, threatening ecosystem health. Some of these contaminants accumulate in lipophilic fish tissues and are maternally transferred to developing offspring, affecting their growth and performance. However, knowledge about the long-term and generational impacts associated with maternal transfer of contaminants is limited in fish. In this thesis, the hypothesis tested was that maternal transfer of bisphenol A (BPA) leads to disruption in the developmental programing of growth and stress axes functioning in rainbow trout (Oncorhynchus mykiss), and that these changes are passed on to the next generation. This was tested by exposing oocytes to either control (vehicle;
