The ichtyofauna of the Porto-Lagos Lagoon in northern Greece was sampled over 17 months, using a bag-seine net, to investigate factors influencing species seasonal composition and abundance. Of the 35 resident, migrant and straggler species caught, representing 22 families, the most numerically dominant species were
Atherina boyeri (46.4% of total catch), which today is the most economically important species, followed by Pomatoschistus marmoratus (28% of total catch) and Aphanius fasciatus (9.1% of total catch). Mugilidae and Sparidae were the most diverse families. According to various diversity indices, the lagoon’s ichthyofauna was found to be most diverse in May 1990; taxonomic spread however, as shown by the taxonomic distinctness index (Δ*), was lowest in July 1990, when the greatest monthly water temperature range was observed (13.5 °C). Overall fish relative abundance was positively correlated with the maximum monthly water temperature ( r 2=0.32, p < 0.05). The NMDS and cluster analysis performed on the bag seine catches showed four groupings, based mainly on the life history of the species. The main group consisted of all the resident species of the lagoon and four mugilid species that were present throughout most of the sampling period. The second group consisted of marine migrant species that spent a short period of their life in the lagoon. Marine migrants and one marine straggler that were found once or twice formed the third group, while the fourth group consisted of species with casual presence. The importance of Porto-Lagos Lagoon as nursery and feeding area for marine species was confirmed by the catch of young individuals of several marine species.
