Introduction At the request of the Northwest Power and Conservation Council and the Pacific Northwest Aquatic Monitoring Partnership (PNAMP), the ISAB reviewed the design and proposed statistical analyses in a study comparing stream habitat monitoring protocols, which will be carried out by PNAMP. The study objectives are as follows:

Sound production, Seasonal isolation, Overwintering, Aquatic insects The water boatmen Corixa dentipes and C. punctata produce an acoustic mounting signal when beginning to copulate. Automated recording o f this signal over the entire life cycle of the animals reveals that the main mating period of C. punctata occurs in autumn and that o f C. dentipes, in the spring. In the case o f C. punctata...

aquaculture is the fastest growing food production sector in the world today, supplying half of global fish consumption. Production from capture fisheries has stagnated and is unable to meet the anticipated growth in demand. current indications are that asian and african aquaculture will need to grow substantially to meet future demand for fish and must do so largely by increasing production pe...

Inland fisheries are a vital component in the livelihoods and food security of people throughout the world, as well as contributing huge recreational and economic benefits. These valuable assets are jeopardized by lack of research-based understanding of the impacts of fisheries on inland ecosystems, and similarly the impact of human activities associated with inland waters on fisheries and aqua...
