Crecimiento y mortalidad natural del pez Haemulon aurolineatum Teleostei: Haemulidae del suroeste de la isla de Margarita, Venezuela. Escuela de ciencias aplicadas del mar, Departamento de acuacultura. The curve of growth in length was fit to the model of von Bertalanffy, and described anexponential curve, where growth accelerated until the two years of age.

Epub September Se muestreo un total de 2 ejemplares, desde julio de hasta junio de La estructura de tallas de la muestra estuvo comprendida desde El peso total de los machos estuvo comprendido entre El valor del t 0 calculado fue de 0. Se compararon diferentes curvas de crecimiento de H. La gama de longitudes encontradas en el presente trabajo, tanto para machos como para hembras coincide parcialmente con lo reportado para la misma especie por diferentes autores.

En las costas Venezolanas, varios autores registraron diferentes tallas de H. Por otro lado, Manooch y Barans , capturaron un ejemplar de Por su parte, Pauly y Sparre et al.

Allometric growth in cuban gar (Atractosteus tristoechus) larvae

Estas novedades evolutivas. Anadara tuberculosaAnadara similisGeometric morphometric, Pacific coast of Colombia. The other body heights preanal and postanalhowever, recorded an isometric growth Table 1. Four different concepts of allometry are distinguished: The results of the allometric analyses carried out on Cuban gar larvae for the paired and caudal fins, as well as for the growth of the trunk and cephalic region, make it possible to state the following: Balon EK The theory of saltatory ontogeny and life history models revisited. Di or triphasic growth can be described by two or three different growth curves, respectively. A significant morphogenesis occurs during the early development when the larvae need to adequately and timely form somatic and visceral systems, as well as specialised structures for an optimal interaction with the environment Dettlaff et al.


The length-weight relationship and condition factor K are useful descriptors in population fish biology, because they provide essential information on growth strategies, nutritional status and reproduction. They are also parameters widely used to compare the condition of aquatic systems with varying degrees of human intervention. Therefore, understanding the dynamics of populations in pristine ecosystems, provides relevant basic information to understanding changes or effects in populations under these pressures. The San Pedro river Valdivia basin , southern Chile, is a system characterized by its current low intervention level, high fish diversity and low abundance of introduced species. We describe the length-weight relationship and condition factor of 12 native fish of the San Pedro river, for over two annual cycles, analyzing their growth strategies and seasonal variability in condition factor.
