The main elements related to planning have been addressed including natural resources (land and water), criteria of farmed species, marketing and environmental factors. The presentation introduced some illustrated case studies to demonstrate how proper or improper project planning may lead to the success or failure of aquaculture projects. The importance of economic evaluation and the need to go side by side with technical components has been emphasized. The presentation emphasized on issues related to natural resources which could be amended versus issues which could threat the future of planned projects.
