Description

Although numerous structures have recently been built to provide upstream and downstream passage of river herring at migratory barriers, few have been quantitatively evaluated for their performance. Basic monitoring of these passage structures by simple visual counts of fish also tends to be relatively qualitative in nature, and often inaccurate. The scale of passage structures for river herring offers many opportunities for comprehensive evaluations and monitoring that are often not feasible with other anadromous fishes. Several technologies have been developed to perform more quantitative evaluations and accurate monitoring of passage structures and river herring runs, ranging from mark-recapture studies, automated video recording, and telemetry; these methods are reviewed and summarized in terms of level of effort, cost, and data return. Newly-developed numeric methods for analyzing data to estimate attraction, spatial/temporal passage performance, and assessment of passage performance relevant to restoration goals are also described.

Comments

Dr. Alex Haro is a Research Ecologist at the S.O. Conte Anadromous Fish Research Laboratory (U.S. Geological Survey) at Turners Falls, Massachusetts, USA and serves as a Principal Investigator and Section Leader of the Fish Passage Engineering Section at the Conte Lab. His present work involves migratory fish behavior, design, engineering, and evaluation of fish passage structures, fish swimming performance, and ecology and management of American eels. Dr. Haro provides extensive basic and applied research and advice to state, national, and international agencies, NGOs, and the private sector on fish passage technology and operations. He is also an Adjunct Associate Professor at the University of Massachusetts Department of Environmental Conservation and serves as a major advisor for graduate students, as well as an instructor for courses in fisheries biology
