Scientists from eight countries presented papers at the first International Symposium on Fish Physiology, Fish Toxicology, and Fisheries Management, which was held on the campus of Zhongshan University, Guangzhou, PRC. The proceedings includes 30 papers presented in sessions on the reproduction and growth of fish; on the physiology, behavior and genetics of fish; and on toxicology and risk assessment in aquatic systems. Papers address hormone functions, sex manipulation in aquaculture, cloning and induced breeding in fish, calcium and phosphorus requirements, fish diets and metabolism, and utilization of inorganic nitrogen. Descriptions are provided concerning research on gas transfer, gill ventilation control, carbon dioxide effects, ammonia effects, environmental acidification effects, phototaxis, sex pheromones effects, gonad maturation, antifreeze protein genes, and bioenergetics modeling. Presentations also covered fish conservation, water quality protection, predictions of chronic effects levels, chemical toxicity, and toxicant modeling.
