Specimens of both sexes were collected in the Messologhi-Etoliko lagoon in western Greece. The equation used for the morphometric character Y was dY/dTL=a times b times TL-b-1, which gives information on the tendency of each morphometric character to grow in relation to total length and also gives a quantitative expression of this and the size of each character. The equation used for length-weight relationship was W= a times TL-b. It is shown that the differential increase in the morphometric characters in relation to the increase in total length gives a tendency for the body of L. saliens to be slender and the body of L. ramada to be spherical. This was confirmed by data on length-weight relationships.}, keywords = {Pisces}, author = {Minos, G. and Katselis, G. and Kaspiris, P. and Ondrias, I.} } @article {13245, title = {Composition, temporal dynamics and regional characteristics of small-scale fisheries in Greece}, journal = {Fisheries ResearchFisheries Research}, volume = {73}, number = {1-2}, year = {2005}, note = {Cited By (since 1996): 2Export Date: 4 September 2006Source: ScopusReferences: Bertignac, M., Les rendements par espece de la peche chalutiere hauturiere francaise de l{\textquoteright} Atlantique Nord-Est entre 1972 et 1989 (1992) Aquat.

The sector consisted of 19,052 small-scale fishing vessels and about 29,000-35,000 fishermen by the end of 2002. Both the number of fishermen and vessels show a decreasing trend in the last decade. The social importance of small-scale fisheries varies considerably between the Greek prefectures and is relatively higher in the insular ones. A total of 17 fishing gears and 62 target species was reported. The most important me?tiers were identified using multivariate methodology and were characterised by fishing gear, target species, locality and season. Most of the me?tiers are localized, but some are existent all over the country. Fishing activity follows a seasonal pattern characterising the different regions. The Greek prefectures were also grouped using cluster analysis of data on gear licenses and gear usage to explore the existence of geographic affinity on a broader scale. The results confirm the great heterogeneity and the complexity of the small-scale fishing sector. {\textcopyright} 2004 Elsevier B.V.

This area contains six clearly distinct lagoons with different topographic and hydrological features. The fishery landings of the lagoons are based on the ontogenic and seasonal migrations of the species. The total annual fishery landings of the barrier fish traps are estimated as 195 mt and are mainly composed of 16 species belonging to 8 families. Eel (Anguilla anguilla), the four species of Mugilidae (Liza saliens, L. aurata, L. ramada and Mugil cephalus), the two species of Sparidae (Sparus aurata and Diplodus annularis) and one species of Mullidae (Mullus barbatus) represent more than 92\% of the total annual landings. The composition of the fishery landings varies between lagoons. The cluster analysis showed three groups of lagoons. The first group comprised lagoons in which the landings were dominated by eel, the second group was dominated by Mugilidae species and S. aurata, and the third by L. ramada and M. cephalus. The diversity index of the fishery landings is fairly constant in time, except for the Etoliko lagoon, where repeated anoxic crises decreased the diversity index value to almost zero in 1992. All the landing series showed a dominant annual cycle. Two seasonal patterns of the fishery landings were observed and linked to the fish spawning behaviour and/or their reaction to environmental forcings.

The part of sea bream production is about 60\% of the total production of these species. During the last decade, a spectacular increase in both the number of farms and their production, accompanied by a substantial price decrease and modification of their structure and functioning, has been recorded. These changes resulted in the maintenance in cages of large individuals (more than 500 g) of gilthead sea bream which are potential spawners. The study, based on both the maturity stage and the decrease in individual mean weights during the reproductive period of the species, confirmed reproduction in cages. In parallel, during the last 5 years a remarkable increase (about 80\%) in sea bream landings from the fish trap fisheries of the Messolonghi-Etoliko lagoon, which is a typical nursery for the species, was recorded. The increase was accompanied by a decrease both in price and mean size of the O-group individuals.

The importance of cladocera and copepods decreased with increasing size of the sand smelt, while the importance of bivalve larvae, fish eggs and finfish fry increased with increasing sand smelt size. Seasonal changes in diet composition and prey abundance in sand smelt stomachs were recorded as coinciding with the seasonal composition and abundance of the zooplankton community in the surface layers of Trichonis Lake.
