Value of the Data •Knowledge related to the effect of water velocity on physiological stress can serve as a guideline for the optimal velocity necessary during grow-out phase in captivity [2]. •Crab aquaculturist and crab farmers are benefits on this data since it can be used during the fattening activity of the immature crabs. •Investigation of crab hemolymph and tissue is crucial to understanding the ecosystem's impact on the general functioning of a crab through velocity tolerance. •Experimental data on ecological energy could be further useful to predict several ecological hypotheses, such as constructing relationships between different velocities and offspring or reproductive ability, explaining predator conduct foraging and confirming organism physiological status [3].
