Fish farming generates wealth and food worldwide (FAO, 2018). The department of Valle del Cauca (Colombia) is consolidating as one of the most conducive places for the development of this activity (Merino, 2014). However, it is necessary to obtain more technical-scientific information about this activity (Merino et al., 2013). In this valley, not only converge the ideal hydrographic and climatic conditions for fish farming, but also a strong and develop agro-industry (El País, 2017). In this sense, the possibility of expanding and diversify the economy in Florida, Valle del Cauca, becomes in an important generation of development in this municipality to reduce the rates of unemployment and violence (Guevara, 2011). Consequently, it is necessary build new productive chains such as fish farming in a place where for decades exist armed conflict. The aim of this study was to know the main environmental variables necessary to implement a tilapia culture in an artificial lake farm belonging t o the "El Tamboral " association (150 beneficiary families- 2 former guerrilla). In addition, to socio-economically characterize the fish farming activity in the municipality to know processes of purchase, sale, commercialization of this species. Between March-August 2019 were realized 286 and 40 structured and close-ended interviews with 15 question to Florida´s citizens and 13 to food establishments , respectively. The people consider themselves white (58%). They consume mostly Tilapia and trout (41%) and frequently don´t eat fish because of its high cost. People don´ t eat fish because of its flavor and cost (25%). They like fried fish (67%) . The levels of marketing and advertising of the product must be improved (40%). The restaurants mostly claimed not to sell fish (66%). Others, sell various types of fish, being the tilapia the most representative . The sale is made every day (60%). It is bought both in the supermarket and the grocery between 0.6 to 1.2U$ and restaurants sold it between 2.9 to 3.2U$. The cost for the start-up the fish farm ( without workers payment ), was estimated at 735U$, gain 151-200 U$ per month (7-10 months- 2000 alevin in 1 tank 19 x 8 x 0.5 m). Water quality was measurement.
