Megjegyzések:	During our study, the growth features of European perch (Perca fluviatilis) from two habitats were comparedin the area of Middle-Tisza. 226 perches were collected from Tiszavalki-medence of Lake Tisza (111 pcs) in27 October 2014 and Rakamazi-Nagy-morotva (115 pcs) in 3 November 2014. The relationship betweenstandard length (SL) and total length (TL) was described by linear regression. The relationship in theTiszavalki?medence was TL = 1.1589 SL + 1.2049 (r2 = 0.99) and in the Rakamazi-Nagy-Morotva was TL =1.1351 SL + 3.6436 (r2 = 0.998). The relationship between standard length (SL) and body weight (W) was W =1?10?5 SL3.2166 (r2 = 0.979) in the Tiszavalki?medence and was W = 3?10?5 SL2.9277 (r2 = 0.968) in the Rakamazi-Nagy-Morotva. Based on the body length distribution three different size groups (age groups) were identifiedin both places. The avarage SL of these groups were 66; 85.9 and 112.3 mm in the Tiszavalki-medence and 52.9; 77.5 and 105.1 mm in the Nagy-morotva. The observed growth in the Tiszavalki-medence was similar tothat discrebed in other Hungarian waters, but in the first two years the growth of perches in the Rakamazi-Nagy-morotva was slower then in the Tiszavalki-medence and in the other Hungarian places. The results ofthis fact maybe the different water and nutrient supply and also the oxygen levels.
