Age and growth of three species of Ariidae (Siluriformes) in coastal waters of Guinea IRD
Conand, François; Camara, S.B.; Domain, François.
The growth of three West African marine catfish, #Arius heudeloti$, #A. parkii$, #A. latiscutatus$ (Siluriformes, #Ariidae$), was studied in Guinea by examining sections of the first dorsal spine. Age and growth interpretations were possible for fish up to 40 cm and the three species reveal a similar biology. A single annulus is formed each year at the beginning of the rainy season. Growth seems to be slow, and 40 cm fork length individuals are about 6 years old. Three ariids can reach large sizes (80 cm or larger), which may indicate that the natural mortality is low. This adaptativeness is probably related to their strong body protection against predators, their low fecundity and egg incubation. (Résumé d'auteur)

Age determination and the hypothesis of annual double cycle of growth in Sardinella aurita IRD
Ndah, K..
La détermination de l'âge des poissons selon le nombre de marques déposées sur les pièces dures du corps, notamment les écailles, les otolithes, les os operculaires est bien connue. Toutefois, il est nécessaire d'établir la périodicité annuelle ou saisonnière du dépôt de telles marques. Les premières observations d'écailles de #S. aurita$ semblent montrer l'existence de deux cycles annuels de croissance. Ce phénomène s'expliquerait par l'existence des upwellings mineur et majeur qui constituent deux périodes favorables à la croissance. Néanmoins plus de 18 mois d'observation sur les écailles seront nécessaires pour rejeter ou accepter cette hypothèse d'un double cycle annuel de croissance. (Résumé d'auteur)

Age determination of eels in the French Mediterranean lagoons using classical methods and an image analysis system IRD
Panfili, Jacques; Ximénès, M.C.; Do Chi, T..
Several methods are used for age determination of eels in the French mediterranean lagoons (observation of the whole otolith after clearing, grinding and polishing, dyeing, SEM and image analysis). Two types of otoliths are observed depending on the width of the growth rings which is probably related to the environmental conditions. Furthermore, the growth checks are located nearby or inside the opaque rings. A computer assisted method is developed, with reference to the other methods, with the aim of improving the efficiency of collecting and processing age and growth data. With further developments and increasing knowledge of life-history of elvers and juvenile eels, it seems possible to use an image analysis system for ageing eels in lagoons....

Aging of adult tropical reef by otoliths : a comparison of three methods on Diagramma pictum IRD
Baillon, Nathalie; Kulbicki, Michel.
Age determination for #Diagramma pictum$, (n=102), were conducted using three methods. The two first methods are based on the counts of annuli on respectively whole otolith cross sections. The third method use the decrease of otolith daily growth increment (DGI) density with age. The growth curves found with the first two methods are comparable and similar to previous results. However, the analysis of life history traits such as size at first reproduction indicates that these methods are likely to underestimate growth. The use of DGI density yields a faster growth curve. To establish this curve the relationships liking fish size to otolith radius and DGI density to otolith radius are needed. The final growth curve is particularly sensitive to changes in...

Are tsetse fly populations close to equilibrium ? IRD
Jarry, M.; Gouteux, Jean-Paul; Khaladi, M..
Glossina or tsetse flies, the vector of sleeping sickness, form a unique group of insect with remarkable characteristics. They are viviparous with a slow rhythm of reproduction (one larva approximately every 10 days) determined by the regular ovulation of alternate ovaries. This unusual physiology enables the age of the females to be estimated by examining the ovaries. The resulting ovarian age structure of tsetse fly populations has been used to develop research into the demography of tsetse flies. Several authors have proposed methods of estimating populations growth rates from ovarian age distribution data. However, such methods are applicable only when the growth rate (lambda) is equal to 1 (i.e. the intrinsic rate of increase r is equal to 0). In fact...
