In the case of the Cuban gar, larval behaviour is characterised by periods of resting, while executing corporal undulation movements. Siendo Anadara tuberculosa y A. Fish Physiology and Biochemistry These results reveal the rapid development of this system and ensure that the essential organs for feeding are developed first. The growth patterns recorded for the head and the snout in this species were positively allometric for length and negatively allometric for width, indicating a lengthening and narrowing of the cephalic region during early development.

These patterns of allometric growth reflect morphoanatomical growth priorities in agreement with their importance regarding primary living functions that guarantee an appropriate survival Sala et al.

For this reason, the relationship between the growth of these fins and the maneuverability function in favour of an effective swimming for feeding as reported for other fish species remains in doubt for Cuban gar. Kovac V Synchrony and heterochrony in ontogeny offish.

North American Journal of Aquaculture Fuiman LA Growth gradients in fish larvae. Differences due to size are not sufficient to determine the existence of different populations, mainly because these differences may happen due to differences in fishery allmetrico increasing the ratio of smaller sizes. Biological Journal of the Society, Experimental design, sampling and measurements After hatching, larvae were distributed in three 15 L circular fiberglass tanks 6. Inflexion points were determined using iteration procedures according to Snik et al.

The X value where the slope changes is called the inflexion point. Los pueblos del mar.

Intra-specific comparison showed that areas where the organisms were collected do not affect valve configuration. However, Cuban gar larvae are characterised by an crecimienho immobile behaviour, and these corporal oscillatory movements do not allow them to move in the water column.

The left valve of the shell was used to draw seven landmarks and evaluate the geometric configuration of the shell. Studies on Neotropical Fauna and Environment This term was coined by Huxley and Teissier and describes the relationships between organism dimensions and changes in the relative proportions of these dimensions with changes in absolute size Goldman et al.
