Keresztessy, K.: The fishes of the Bátorliget Nature Reserves

This project was supported by the Ministry of Environment. We could catch the following fishes: Rutilus rutilus (Linnaeus, 1758) Scardinius erythophthalmus (Linnaeus, 1758) Leucaspius delineatus (Heckel, 1843) Gobio gobio (Linnaeus, 1758) Carassius carassius (Linnaeus, 1758) Cobitis taenia (Linnaeus, 1758) We could only find fishes in two small watercourses; in the Pilis-Pirigye stream and in the Nádasdűlő watercourse. To sum it up, the Nature Reserves is poor both in fish species and in number of individuals. Table 2. The examined specimens and their estimated ages Pilis-Pirigye stream Nádasdúlő watercourse Rutilus rutilus Scardinius eryth. Leucaspius delineatus Gobio gobio Carassius carassius Cobitis taenia 5 specimens, 3 years 1 specimen, 3 years 1 specimen, 1 years 2 specimens, 3 years 2 specimens, 2-3 years 1 specimen, 2 years 3 specimens, 2-3 years 1 specimen, 2 years 3 specimens, 3-4 years Forty years ago Gobio gobio, Cobitis taenia, Leucaspius delineatus were found in the waters of Bátorliget. During our research we caught these three species and in addition we found three other species, such as Rutilus rutilus, Scardinius erythrophthalmus, Carassius carassius (but they occured only in limited numbers).
