摘要: Abstract This experiment was conducted to determine if quagga mussels (Dreissena bugensis) settle and grow on different types of artificial substrates preferentially in Lake Mead, Nevada–Arizona, one the first known populations mussel western United States. Six substrates, acrylonitrile butadiene styrene (ABS) plastic, high density polyethylene (HDPE) concrete underlayment board (CUB), aluminum, stainless steel fiberglass were cut into 10 cm squares placed at depths Boulder Basin Mead for approximately 1 yr a modified randomized block design. Half removed replaced every 2 mo, other half remained water duration study. No preference substrate type could be determined, but settlement limited by depth. Mussel from 6–28 m significantly greater than 32–54 (F = 5.54; p < 0.001). divergence is ...
