The world’s population is rising and the subsequent demand for high protein sources of food is rising with it. A push for healthier sources of protein is also an increasing demand. Hence, aquaculture is rising in prevalence and importance in today’s society with the increase in fish consumption and the limitations imposed by normal fishing methods. Aquaculture offers a solution to these issues by providing high protein foods that require less space to farm, a lesser time to harvest, and a lower cost to produce, and it is lesser detrimental to the environment. However, current aquaculture techniques involve the use of chemicals to reduce disease and mortality within the crops, caused by stress. In order to provide solutions to the problems of farming and the needs of the people without the use of potentially harmful substances many researchers are looking in to the decrease of stress responses and to the increase of immune responses to increase growth and produce quality products – both from fish and shellfish. In this presentation, I will highlight all these issues and suggest solutions.
