The effect of temperature and dietary energy content on female maturation and egg nutritional content in Atlantic salmon
The environment experienced by a female influences reproductive traits in many species of fish. Environmental factors such as temperature and diet are not only important mediators of female maturation and reproduction but also of egg traits and offspring fitness through maternal provisioning. In thi...
