Hematology, proximal composition and fatty acid profile comparison from wild and farm-raised juveniles of green guapote Mayaheros beani (Jordan, 1889)

Sustainable aquaculture of the green guapoteMayaheros beanirequires better understanding their physiology and composition. In that context, this research focused on the study of hematology, proximal and fatty acid (FA) composition of wild and farmed green guapote. Results showed no significant differences between wild and farmed fish in red blood cell count (1.77-2.57 x10(6)cel mu L-1), hemoglobin (11.6-15.1 g dL(-1)), glucose (68-115 mg dL(-1)) and the crude protein of whole body (51-58%). However, farmed fish showed significantly higher crude lipid (21.2 +/- 0.33%) of whole body compared with wild ones (6.80 +/- 0.42). Otherwise, wild fish had higher n-3 FA (14.18 +/- 1.84%) than farmed fish (11.50 +/- 1.97%). Because farmed fish showed a feed conversion ratio of 2.03 +/- 0.8, results seem to indicate thatM. beanirequire a specific balanced diet to improve its performance. Further research is required to understand the nutritional requirement ofM. beani.
