| description | For the accomplishment of this work, 510 specimens of Hoplias lacerdae were used from one to 30 days after hatching, with the objective of studying the mesoscopic morphological characteristics that enable this species, in the initial phases of its development, to present adaptations for movement and the capture of exogenous food. The yolk sac larvae at 11 days after hatching have the potentiality to capture exogenous food, i.e. prey, even before the total yolk absorption which happens at 12 days, presenting in this phase: an open mouth at one day after hatching, displaying the terminal position at four days; notochord flexion, that takes place at seven days and provides greater efficiency of movement; pectoral fins, also developed at seven days, which facilitate its balance and direction in the water column; formation of the dorsal and anal fins at eight days and the pelvic ones, at 11 days. |
