Abstract

The objective of this work was to compare the morphometry of hatchery‑reared and wild‑caught mangrove crab (Ucides cordatus) megalopae. Ten U. cordatus megalopae of each group (hatchery‑reared and wild‑caught) were individually analyzed using a stereoscopic microscope equipped with an ocular micrometer. Length, width, and height of all megalopae were measured, and the size of body appendices was determined. The results indicate that the hatchery‑reared megalopae are more robust than the wild ones. Furthermore, some significant differences in the size of certain appendices can be cues of the kind of alterations that hatchery‑reared individuals experience.
