Observations on the spawning habits of the yellowfin shiner, Notropis lutipinnis. In a small South Carolina stream, aggregations of the small shiner, Notropis lutipinnis, spawned on the surfaces of dome-shaped gravel and pebble nests. The nests were commonly over 50 cm in diameter and the sizes of pebbles comprising them were much too large for the shiners to have independently constructed the nests. Original nest construction can be attributed to the larger chub, Nocomis leptocephalus. [eng]
