Resumen:
Several decapod crustaceans are invaders, but little is known about the biological characteristics that potentiate the success of these decapods in invaded ecosystems. Here, we evaluate and describe some aspects of the reproductive biology and development of Lysmatavittata, an invasive shrimp species in the Atlantic Ocean. In addition, we intend to provideimportant insights into the biology of invasion by comparing the reproductive traits of thisshrimp with some of the predictions about aquatic invasive species. We used experimentaland laboratory observations to evaluate the functionality of protandric simultaneoushermaphroditism (PSH), the macro and microscopic development of the ovarian portion ofthe ovotestes, the reproductive cycle, and the embryonic development of L. vittata. We confirm the functionality of PSH in L. vittata. This shrimp has a rapid reproductive cycle; theovarian portion of the ovotestes develops (mean ± SD) 6.28 ± 1.61 days after spawning.Embryonic development also occurs over a short time, with a mean (± SD) of 8.37 ± 0.85days. The larvae hatch without macroscopically visible yolk reserves. Our study providesevidence that the invasive shrimp L. vittata has reproductive and embryonic developmentalcharacteristics (i.e., short generation time and high reproductive capacity) that may be favorable to the establishment of populations during invasive processes.
