Abstract
This paper identifies patterns of morphometrics on four populations of M. Furnieri present in lagoon coastal and estuary ecosystems, for which were collected 102 individuals caught at different sites by the artisanal fishery fleet. Were designed a morfometrics measures net from 12 anatomical points. Two functions discriminated morphometrically the four populations and selected 10 measures to characterize each one. The main characteristics were the body height, length of caudal peduncle, basis of the first and second dorsal fin, and the size of the mouth. We attributed the change in the morphol-ogy of the stocks to the characteristics of the ecosystems they inhabit. Due to the lack of information, we suggest studying trophic relationships and their effect on morphometric variation in a way which will provide support to policy makers in formulating management plans that seek sustainable and rational utilization of fishery resources in the Colombian and Venezuelan Caribbean.
