Sažetak
The total of 45 nematode species was found at the investigated sites of the eulittoral of Lake Sakadaš during 1998: 12 deposit feeders (bacterial feeders), six epistrate feeders (algal feeders), eight chewers (predators/omnivorous), and 19 suction feeders (plant feeders/omnivorous). Chewers were the major group of nematofauna at the eulittoral of Lake Sakadaš - they comprised 68.28% of total nematofauna at submerged site A, 70.13% at site B (at the water and land point of contact), and 54.16% at emerge site C. The chewers had the highest relative abundance recorded: Brevitobrilus stefanskii, Mononchus aquaticus and Tobrilus gracilis at sites A and B, and B. stefanskii, M. aquaticus and Paramononchus sp. at site C. Suction-feeders were the next important nematofauna group: 19.98% at site A, 23.60% at site B, and 36.97% at site C, followed by deposit-feeders (5.98-11.78), whereas, epistrate-feeders had the lowest abundance (<2%). The irregularities of water level and the quantity of food available had the major influence on the changes in the distribution of nematode feeding-types.
