Main Article Content
This research is a gathering of knowledge from tilapia philosophers and farmers with outstanding techniques of practice in the northern part of Thailand. All collected information was analyzed under the basis of good aquaculture practice (GAP) and explicit knowledge was developed for the achievement of Thailand aquaculture sustainability. From 5 philosophers and 3 farmers, the practices were divided into 3 main activities: (1) Breeding and nursing: The enhancement of the reproductive performance of broodstocks and the increasing rate of survival and sex reversal of tilapia fry, (2) Tilapia culture in the earthen pond: management technique to reduce the production cost, increase productivity and the quality of fish fillet, and (3) Tilapia culture in cages: Techniques to increase growth, survival rate and benefit of production. Most techniques are derived from the experience gained through the learning process in tilapia aquaculture by integrating the landscape, climatic and local resources utilization for successfully cultivated Tilapia culture. The knowledge gained from this study can be further developed as a knowledge base for sustainable tilapia farming in the northern region and also whole tilapia culture industry.
