Sažetak
The embryonic and early larval development of the laboratory-reared largescaled scorpionfish, S c o r p a e n a scrofa is described. Fertilized eggs were pelagic and elipsoidal with a homogeneous and unsegmented yolk (no oil globule) surrounded with transparent gelatinous layer. Eggs ranged in diameter from 0.83 to 0.95 mm, with a mean (± ; ; SD) of 0.89 ± ; ; 0.121 mm. Embryonic development lasted 31 h 45 min at a mean temperature of 25.6°C. Newly hatched larvae measured 2.09 ± ; ; 0.07 mm total length in average (range 2.0-2.25 mm). The yolk was completely absorbed by day 4 after hatching. Changes in length and shape of yolk-sac larvae and larvae during the first seven days after hatching are also presented.
