Two regions were established (north and south of the Euripos Strait). The red bandfish grows allometrically (slope of length-weight regressions .ltoreq.2) and relatively rapidly until age 4 or 5 years. It is proposed that this rapid linear growth represents an adaptation which evolved to reduce the vulnerability of red bandfish to whole-fish swallowers. Back-calculated lengths-at-age showed significant differences between regions and between sexes. Males were larger than females after age 2 years. Maximum age of northern fish was also higher than southern fish (8 and 5 years respectively). Southern fish grow at a faster rate (K = 0.379) but to a significantly smaller size (L.varies. = 424.8 mm T.L., W.varies. = 25.1 g) than northern fish (K = 0.214, L.varies. = 676.1 mm T.L., W.varies. = 90.9 g). Mortality rates (total and natural instantaneous mortalities) of southern fish were also higher than northern fish. We suggest that these variations represent responses to the different conditions of temperature and food availability prevailing in the two regions.}, keywords = {Pisces}, author = {Stergiou, K.

The overall male: female ratio did not differ significantly (chi-2 = 4.57, P lt 0.05) from the theoretical 1:1. However, the male:female ratio differed with season and length class and these differences are most probably related to sexual differences in growth rate, natural mortality rate and energetic cost of eproduction. Red bandfish spawns over an extended period, from late spring to mid autumn, with larger females spawning earlier than smaller ones. Males reach maturity at a larger total length, 299 mm, and age, 2.6 years, than females, 219 mm and 1.9 years respectively, a fact most probably indicating the existence of social structure in red bandfish. Finally, red bandfish matures at a comparatively smaller length and age than other fish species.}, keywords = {Pisces}, author = {Stergiou, K.

Potential scenarios of its dispersal were examined using allozyme analysis of several populations from the Iberian and Greek peninsulas. Based on Nei genetic distances, the most divergent populations were the populations inhabiting lakes, Lake Trichonis in Greece, and Ruidera Lakes in Spain. Their high divergence suggests their early isolation from the main ingroup populations. In contrast, low genetic distances were found among river populations regardless of geographic location. There was a correlation between genetic distance and geographic distance among Iberian river populations, suggesting that dispersal following the colonization of fresh water occurred via the sea to nearby, unconnected river basins. The ancestor of S. fluviatilis may have been a euryhaline species, allowing incursions into fresh water and subsequent dispersal via the sea. This dispersal scenario could theoretically be combined with multiple colonization episodes. The two old lake populations shared a unique allele at the Pgdh-A locus in high frequency with its closest relative S. pavo, which was absent from other populations. This may indicate two initial incursions into fresh water by a wide-ranging marine ancestor that possessed this allele. Differential selection on this allele in lake habitats or convergence are less likely possibilities. Thus, the present distribution of S. fluviatilis appears to stem from a combination of {\textquoteright}raceme{\textquoteright} origins (i.e., more than one colonization episode) and subsequent dispersal and divergence in new watersheds.}, keywords = {Pisces}, author = {Perdices, A. and Doadrio, I. and C{\^o}t{\'e}, I.M. and Machordom, A. and Economidis, P. and Reynolds, J.D.} } @article {7517, title = {Benthic fauna of the Evvoia coast and Evvoia gulf.
