	abstract = {The Prespa nase, Chondrostoma prespensis, lives exclusively in Lakes Mikri and Megali Prespa in north-western Greece. The Prespa nase fishery catches in both lakes began declining in the early 1980s, probably due to overfishing. However, the population of Lake Mikri Prespa, which has been monitored from 1984 to 1996, has shown an increase since the early 1990s thanks to the use of larger mesh size and a decrease in the fishing effort of the fishery. The population of Lake Mikri Prespa seems unique for the genus because it lives in a lentic ecosystem which is lacking any permanent inflow streams, the Prespa nase being therefore forced to spawn within the lake. In contrast, the population of Lake Megali Prespa do undertake spawning migration into permanent inflows. This migration was studied in 1995 and 1996 in the Agios Germanos stream, starting late April to late May. Only large mature fish visit and spawn in this stream, the migration taking place exclusively at night. Migrating at night may protect them from diurnal predation from waterbirds.},

	abstract = {The population of the Dalmatian Pelican was in decline in many countries, but protection in all countries of the West Palearctic coupled with active conservation measures has resulted in a stabilization of numbers though few colonies are, as yet, showing any increase. Colour ringing has revealed considerable new information on movements: birds breeding in Europe wintering the east Mediterranean, mainly Greece and Turkey. Breeders in the former USSR winter either in the Caspian Sea are or in wetlands from Iraq to western India. More information is abailable on spring arrival and autumn departure from colonies. Knowledge of diet of chicks has been acquired from regungitates. In some areas there are interannual variations in prey caught. Overall, diet composition depends largely on relative abundance and distrubiton of prey species. The pair bond is confirmed as lasting for the breeding season only. Adults mostly feed in the colony area, but may commute from 10 to 50 km to obtain food. New data are presented on several aspects of breeding, including nest size and inter-nest distance, incubation and fledging periods and breeding success.},

	abstract = {Twenty-three taxa of fish have been identified from the Prespa lakes. Eleven of these have been introduced or translocated, and 7 of the remaining 12 are endemic to the Prespa lakes. This high proportion of endemism requires confirmation because the systematic position of several of the species and subspecies remains uncertain. The absence of a predatory fish in Mikri Prespa, the occurrence of trout in Megali Prespa, the presence of eels in both lakes and the occurrence of many rheophilous fish species typifies the fish communities of these two lakes. Monitoring of the fish population in Mikri Prespa, from 1984 to 1994, showed apparent stability or a slight increase in catches during this period. Not all the introduced species have been able to establish populations and their impact on the indigenous populations is yet to be defined. A spectacular re-establishment of the carp population, following the crash of the stock of this species in the 1970s-1980s, was recorded in the spring of 1991. The past and present situation of the fisheries in lakes Mikri and Megali Prespa is described, and their productivity and yields are analysed. Particular attention is given to a traditional fishing method unique to the Prespa region: "pelaizia" fishing. The factors involved in the temporal trends in the fisheries are identified and analysed. Recommendations for the management of the fish populations and the fisheries are proposed, so that the sustainability of this resource and the survival of the endemic fish species can be ensured. {\textcopyright}1997 Kluwer Academic Publishers.},

	abstract = {The breeding biology of the Dalmatian Pelican Pelecanus crispus, a vulnerable bird species in the Palaearctic, has been studied for 7 years at Lake Mikri Prespa, a continental wetland and Tsoukalio lagoon, a coastal wetland within the Amvrakikos Gulf. The two colonies showed stability, with fluctuations in the number of breeding attempts each year varying by about 30\% over a period of 7 years. The date of arrival at the breeding sites and the date of laying of the first egg varied between mid-February and mid-March. The egglaying period (including renesting) varied between 18 and 114 days between years. The annual average clutch size varied between 1.60 and 1.94 eggs per nest. The incubation period averaged 31.4 {\textpm} 1.4 days. The overall hatching success varied from 36\% to 70\%. Egg losses were mainly due to nest abandonment, infertile eggs and eggs rolled from the nests. The Dalmatian Pelican chicks took 11-12 weeks to fledge. Nestling mortality was very low in contrast to other species of pelican. Such a low nestling mortality explains why the breeding success each year is largely explained by the hatching success.},

	abstract = {There are several barbel species in Greece and the taxonomy of some of them is still disputable. In contrast to other countries where barbel can be found exclusively in rivers, there are many barbel populations in Greece living exclusively in lakes. The Prespa barbel, Barbus prespensis, is endemic to the Prespa Lakes, north-western Greece. This study provides the first data on this rare species. Nineteen morphometric parameters and seven meristic features of barbel caught in several lakes and tributaries were compared using discriminant analysis. The host specificity of Dactylogyrus spp. (Monogenea, Plathelminthes) parasitizing the barbel of these lakes was investigated. From 1984 to 1994 the abundance of this barbel remained stable in Lake Mikri Prespa. Some of its life-history traits are presented. The reproductive period seems to start earlier in Lake Mikri Prespa (late April - early June) than in the Lake Megali Prespa system (end of May - mid July). Possible explanations for this difference are discussed. Factors that might potentially threaten the fate of the Prespa barbel population are numerous. They include overfishing, poaching, the introduction of non-native species, water extraction, stream and lakeshore habitat destruction, increasing eutrophication, decreasing water level of Megali Prespa. This year, a new project supported by WWF International started with the goal of producing an Action Plan for the Prespa barbel aimed at better conservation of the species. This plan will focus not only on the species itself, but the entire catchment of the Prespa Lakes will be taken into account.},

	abstract = {Dalmatian Pelicans (Pelecanus crispus) in Lake Mikri Prespa nest on islands of Common Reed (Phragmites) rhizomes formed at the interface between marsh and open water and mostly ranging from 6-80 m2 in area. Nest density from 1984 to 1996 varied from 0.12 to 1.2 nests/m2. Large islands were not more densely occupied than smaller ones. Higher nest densities were observed in the second and third year that a site was used. Islands used for nesting were degraded by weather, water and use by the birds and shrank in size by 1-55\% each year; thus some were abandoned and new ones colonized each year. On the average, sites were used for three years in succession, but initially larger sites were used much longer. Nest site quality was related to island rigidity and the availability of nesting material on it. Numbers of breeding pelicans at Prespa are probably limited by the availability of suitable nest sites and, especially, larger islands, since breeding success is positively correlated with the mean nesting assemblage size (number of breeding attempts/number of sites). Artificial nesting rafts are likely to be more successful the more their features comply with the above findings and the more they enhance overall colony compactness.
