Carassius gibelio is anallogynogenetic fish species, which was introduced into Greek lakes during the late 1970s. The values of the exponent b of the length-weight relationships ranged from 2.33 to 3.38, and varied with the trophic state of the lake. In eutrophic lakes these b values were significantly (P < 0.001) lower than in oligotrophic or mesotrophic lakes. Relationships between the b values and phosphorus concentrations were logarithmic: b = 1.37-0.13 log (PO4-P); total length, fork length and standard length were linear (in all cases: r2 > 0.95). In most of the lakes, populations consisted of females, with the exception of Pamvotis, Doirani and Koronia lakes where a small proportion were males. {\textcopyright} 2006 The Authors Journal compilation {\textcopyright} 2006 Blackwell Verlag, Berlin.}, keywords = {Pisces}, author = {Tsoumani, M. and Liasko, R. and Moutsaki, P. and Kagalou, I. and Leonardos, I.} } @article {13007, title = {Phylogeography and genetic structure of the Mediterranean killifish Aphanius fasciatus (Cyprinodontidae)}, journal = {Marine Biology (Berlin)Marine Biology (Berlin)}, volume = {152}, number = {5}, year = {2007}, month = {October}, pages = {1159-1167}, isbn = {0025-3162}, author = {Triantafyllidis, A. and Leonardos, I. and Bista, I. and Kyriazis, I.

Over a period of twelve months, the spawning behaviour of gibel carp in Lake Pamvotis (NW Greece) was monitored. Females almost exclusively (97.7\%) composed the population, indicating gynogenesis using the sperm of other species. Reproduction began in March and lasted through April. Contrary to the situation reported in other ecosystems, common carp was not present in the spawning grounds during the spawning season of gibel carp; the most abundant other species present at that time was Rutilus ylikiensis. To evaluate the sperm donating results of R. ylikiensis as compared with other species of the lake, eggs of gibel carp were fertilised with sperm of R. ylikiensis (group 1), Carassius auratus (group 2), and Cyprinus carpio (group 3). Also, gibel carp eggs attached to natural substrates were collected from the spawning grounds (group 4). Hatching success ranged from 9-29\% in group 4, compared to 95-98\% in groups 1, 2 and 3. Over a period of 60 days after hatching, mortality ranged from 35\% (group 1) to 56\% (group 3), and specific growth rate from 2.4\% (group 3) to 2.9\% (group 1). We conclude that gibel carp can successfully utilise sperm of ylikiensis roach, which was the best available sperm donor option for the gynogenetically reproducing gibel carp of the lake.}, keywords = {fish, Gynogenesis, Pisces, reproduction}, author = {Paschos, I. and Nathanailides, C. and Tsoumani, M. and Perdikaris, C. and Gouva, E. and Leonardos, I.} } @proceedings {9881, title = {The reproduction and early development of Aphanius fasciatus Nardo, 1827 (Pisces: Cyprinodontidae) in the Mesolongi lagoon (W.

In the mass mortality which occurred in November 1990 it has been estimated that a large part of the fish stock was lost. As a result, fish catches were greatly reduced in the lagoon in the following years. Hydrobiological studies suggest that the deaths are due to the high concentration of H2S in the hypolimnion. The continual enrichment of the water with H2S is attributed to the presence of gypsum deposits in the drainage basin and to the anaerobic breakdown of the accumulated organic matter. The presence of H2S in combination with the physiography of the ecosystem, the influxes of fresh and salt water, the runoff of agricultural chemicals and the strong prevailing southerly winds are responsible for the observed phenomenon.}, keywords = {Fish population, Greece, lagoon, MASS MORTALITY, Pisces}, author = {Leonardos, I. and Sinis, A.} } @article {8648, title = {Reproductive strategy of Aphanius fasciatus Nardo, 1827 (Pisces: Cyprinodontidae) in the Mesolongi and Etolikon lagoons (W.

The reproductive effort (GSI) and histological studies of the ovaries indicate that reproduction is extended and lasts from April to July. Differences in the GSI values were observed between the sites. Fish originating from the sites with higher salinity has significantly lower GSI values and in addition, lay fewer eggs per unit of size (total length, body weight, age) than those from the other sampling sites. The maturation of oocytes stops when the environmental conditions are not satisfactory for the survival of eggs and larvae, and oocytes are subsequently absorbed.}, keywords = {Aphanius fasciatus, Cyprinodontidae, Fish fecundity, Greek lagoons, Reproduction strategy}, author = {Leonardos, I. and Sinis, A.} } @article {8649, title = {Population age and sex structure of Aphanius fasciatus Nardo, 1827 (Pisces: Cyprinodontidae) in the Mesolongi and Etolikon Lagoons (W.

The lake has been recognized as an internationally important conservation Site under European Community legislation due to its rich biodiversity. However, during the last three decades the trophic status of the lake has changed as a result of anthropogenic activity (among others irrigation and domestic sewage discharge), resulting in serious problems. Here we present data about the long-term development in eutrophication of Lake Pamvotis. Water samples were collected and analyzed (water temperature, pH, dissolved oxygen, nutrients, chlorophyll-a) during three monitoring periods: 1985-1989, 1998-1999, 2004-2005. The high nutrient concentrations in the lake water during the three monitoring periods, as well as its eutrophic to hypertrophic status reflect the degree of impact anthropogenic activity has had on the lake. Commencement of a restoration plan in 1995-1996, involving sewage diversion, led to a reduction in external nutrient load and consequently to lower in-lake nutrients and Chlorophyll-a concentrations. Orthophosphate concentration decreased by about 87\%, nitrates fell below 1.20mg/l, whilst the total reduction of inorganic N compounds showed a weaker downward trend, fluctuating between 0.39 and 1.24 mg N/l with an average value of 0.76 mg N/l. However, after a short-term recovery the eutrophic status of the lake remains eight years later (2004-2005), suggesting the importance of the internal loading process and the absence of the top-down effect of fish. This study provides evidence for the need of greater restoration efforts utilized in Mediterranean shallow lakes. (C) 2007 Elsevier Ltd.
