Starvation effects on dry tissue and shell biomass were investigated in the zebra mussel, Dreissena polymorpha, at 5, 15, and 25?C. Subsamples of 30 individuals were examined daily for mortality. A second group was periodically randomly subsampled for dry tissue and shell weights. Extensive starvation tolerance in D. POLYMORPHA is associated with ability to greatly reduce metabolic demand. As this capacity is maximized at low temperatures, mussels may survive winter months with minimal energy store reduction. Extensive tolerance makes starvation impractical for mitigation of D. POLYMORPHA fouling.
The introduction and rapid spread of the zebra mussel in North American waters has caused great concern among industrial and recreational users of these waters. This bivalve mollusk is a biofouler that attaches to any firm substrate (e.g. rocks, piers, water intake pipes, boat hulls) and has already created significant problems for raw water users such as water treatment plants and power plants. Zebra Mussels: Biology, Impacts and Control provides essential information regarding the biology of the zebra mussel in North America and Europe, presents case studies of environmental and industrial impacts, and outlines control strategies. Summary articles detail its life history, origins, and morphology. The book also examines techniques used to culture and maintain this organism in the laboratory. Thirty-two color plates illustrate some of the dramatic problems created by the explosive population growth of this species. Zebra Mussels: Biology, Impacts, and Control is an important resource for ecologists, conservationists, environmental consultants, water quality engineers, regulatory officials, power utilities, and libraries.
This study was undertaken to more fully detail the anoxio tolerance of both D. POLYMORPHA and C. FLUMINEA at different experimental and acclimation temperatures. The results are discussed in relation to both species' depth distributions and the efficacy of anoxia as a control strategy.
About small and large mussels of Dreissena polymorpha that were acclimated to two experimental temperatures to compare oxygen uptake rates using a polarographic oxygen sensor. Total metabolism is higher in larger animals than smaller animals.
Since its introduction to the Great Lakes system in 1985, the zebra mussel has spread so rapidly that it is now considered the most serious biofouling pest of any exotic species. Practical Manual for Zebra Mussel Monitoring and Control will help you counter this threat by leading you through the events you will be faced with when dealing with this biofouler. This book is a crucial source of detection, monitoring, and control methods. It also provides thorough discussions regarding the mussel's biology and potential for harm. Learn how to:
