| dc.description.abstract | Observations on the embrionic and larval development of Cynoscion striatus are presented. The description are made on the basis of material obtained by artificial fertilization. Eggs are pelagic, spherical, 700-840µ in diameter and with single oil globule of 210µ-240µ. The yolk is homogeneous and the chorion has smooth surface. The embryonic development is short and at temperatures of 19°-20°C hatching takes place, 34-36 hours after the fertilization. The larvae at hatching are small, about 2 mm in length and not advanced in their development. The mouth is not functional and the anus is not open. The oil globule is situated in the posterior part of the yolk sac; the position of the anus is close to the posterior end of the yolk sac and the digestice tract forms a straight angle with the anus. The dody and the oil globule are pigmented. The juveniles have a rather deep form of the head and of the body and have their charasteristic pigmentation pattern. The preoperculum is provided with strong spines which disappear entirely in larger specimens. | |
