“…In this study the estimated maximum age of 4+ is consistent with with that reported for other populations of the species (Henderson et al, 1988;Leonardos, 2001;Pallaoro et al, 2002;Koutrakis et al, 2004;Özeren, 2009), whereas several other studies have indicated a maximum age of 2−3+ (Donato et al, 1996;Bertotto et al, 1997;Leonardos and Sinis, 2000;Andreu-Soler et al, 2003). Also, the maximum size of the Lake Trasimeno specimens was similar to that reported in other studies, with a total length of about 10 cm (Leonardos and Sinis, 2000;Andreu-Soler et al, 2003;Bartulovic et al, 2004;Chrisafi et al, 2007).…”

“…These similarities could indicate that despite these populations inhabiting environments with different characteristics, energy allocation for reproduction, growth or fat storage during the year is determined by seasonality (Koutrakis et al, 2004). Both analyses of the trends of Kn and Ks and the GSI of females suggested that reproduction in Trasimeno Lake took place from March to September, similarly to the results reported for other Mediterranean countries such as Croatia (Bartulovic et al, 2004) and Greece (Leonardos and Sinis, 2000). Analysis of back-calculated ages indicated the occurrence of a reverse Lee's phenomenon.…”

“…Similarly, a sex ratio at the disadvantage of the males and a bigger size for females has been found in other populations of the species (Donato et al, 1996;Bertotto et al, 1997;Leonardos and Sinis, 2000;Özeren, 2009). Leonardos and Sinis (1999) reported that strategic mechanisms to protect females have been developed in many fish species and these can include selective predation of males, and greater longevity and greater survival of females during the spawning period.…”

Key-words:Population dynamics, Lee's phenomenon, fishery management, introduced species, Lake TrasimenoThe age, growth and body condition of the big-scale sand smelt (Atherina boyeri) population of Lake Trasimeno were investigated. In total, 3998 specimens were collected during the study and five age classes (from 0+ to 4+) were identified. From a subsample of 1017 specimens, there were 583 females, 411 males and 23 juveniles. The equations between total length (TL) and weight (W) were: log 10 W = −2.326 + 3.139 log 10 TL for males and log 10 W = −2.366 + 3.168 log 10 TL for females. There were highly significant differences between the sexes and for both sexes the value of b (slope of the log (TL-W regression) was greater than 3 (3.139 for males and 3.168 for females), indicating positive allometric growth. The parameters of the theoretical growth curve were: TL t = 10.03 cm; k = 0.18 yr −1 , t 0 = −0.443 yr and Φ = 1.65. Monthly trends of overall condition and the gonadosomatic index (GSI) indicated that the reproductive period occurred from March to September. Analysis of back-calculated lengths indicated the occurrence of a reverse Lee's phenomenon. This could be a symptom of predation or competition, with consequences for young specimens with slower growth and smaller size. L'analyse des longueurs rétro-calculées indique la présence d'un phénomène de Lee inversé. Ce pourrait être un symptôme de la prédation ou de la concurrence ayant des conséquences sur les jeunes spécimens à croissance plus lente et de plus petite taille.

Contrasts in genetic structure and historical demography of marine and riverine populations of Atherina at similar geographical scales

In this paper, we compare the genetic structure and the historical demography of two populations of the sand smelt Atherina boyeri from the rivers Tagus and Mondego (Portugal) with two groups of samples of the closely related marine Atherina presbyter collected on the shore at comparable latitudes. A. presbyter is a pelagic marine inshore fish, while A. boyeri is typically found in coastal lagoons, estuaries and freshwaters bodies. Analysis of mtDNA control region sequences showed that the marine A. presbyter did not display signs of genetic differentiation between sites some hundreds of kilometers apart. On the contrary, A. boyeri showed clear differences between populations. The populations of A. boyeri showed a much lower genetic diversity and younger coalescence times when compared with A. presbyter. We suggest that these differences reflect the interplay between differences in ecology between the two species and the historical impact of the glaciations. While A. presbyter likely moved to the south evading the cold periods, A. boyeri probably went extinct and its populations in Western Europe are recent recolonizations from western Mediterranean refugia.
