Abstract: A reduction of up to 40% of fishing is expected due to the effect of climate change in tropical regions, causing an impact on primary productivity, mainly affecting fish populations that carry out their reproduction in reefs and estuaries; In addition to this, there is no physical and economic access to sufficient, safe and nutritious food to satisfy the population's food needs. For these reasons, aquaculture was thought of as a response to the decrease in fishing and for the production of sustainable food, with a native fish that lives in estuarine and reef areas, such as bream, which due to its biological and economic characteristics may be ideal for aquaculture. For this, an experimental culture was established from December 2011 to March 2012 at the Boca del Río Technological Institute, it consisted of 2 circular ponds of 25 m3, in a closed area, with an aquaculture recirculation system, salinity of 30 ppm (+ 1), pH of 8.3 (+ 0.4) and temperature of 26 ° C (+ 2). At the beginning an aggressive behavior was observed for which shelters were introduced and an improvement was observed. A diet of bivalve molluscs was established, then with a squid-based flan and finally with balanced food. Resulting in that it had good adaptation to captivity, good acceptance of balanced food, obtaining a survival of 95% in cultivation, in addition the bream has a good wreck in the market, for these reasons it is considered an ideal species for cultivation.
