This research was conducted at Emeyedore Vocational High School, Sorong City with a time bracket of two months, the method used was experimental. The results of the Tilapia fish farming "Wanto Group" is one of the tilapia fish farming businesses in Sorong Regency. This business is quite good in every cycle of market needs, but in the last few months (Covid 19) production is less than demand and does not match the results obtained, this mismatch is due to less production of tilapia but market demand is increasing. This obstacle is mainly due to the fact that most of the local fishery business actors are still traditional, with limited facilities and infrastructure and the unavailability of a market for fishery production products. With the problem of tilapia farming, a learning experiment was carried out by involving students in practicum activities.
