Yellowfin shiners spawn in nests constructed by male bluehead chubs. To determine whether yellowfin shiners are obligatory symbionts of bluehead chubs, different densities of shiners were isolated from chubs and presented with artificial nests in stream enclosures. Yellowfin shiners failed to reproduce in the absence of bluehead chubs, indicating that the symbiosis is obligatory for the shiners. Bluehead chubs tended nests by moving stones, which kept the nests free of silt. Nest tending lasted… CONTINUE READING
