The presentation starts with a fact sheet related to fish reproduction. Mode of fish production has been addressed and also the rationality of collecting fish production and fish seeds with a comparison with hatchery produced seeds. Fish sexual maturation in relation to influencing factors has been discussed in this presentation. Hatchery management is adequately addressed including key issues such as water in regard to quality and quantity as well as temperature and light. Hatchery technologies (natural – artificial) are covered on examples of aquatic organisms. The sources and maintenance of brood stock is addressed (e.g. feeding, overwintering).

Planning of aquaculture projects (updated 2013 version)
This updated version of the planning of aquaculture projects addresses planning-related issues that considers the definition of aquaculture systems in relation to productivity and/or management issues (feeding, water exchange, and aeration). 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.
