Aquatic Ecology and Fisheries Studies

Amnis Opes Fish and Ecological Studies

AOI incorporates extensive practical experience and robust scientific knowledge into the design and execution of scientifically sound ecological studies. We believe that a multi scale – watershed approach is important to not only successfully answer ecological questions but also understand how the landscape and land use affects ecological processes. We balance this “big picture” approach with the requirements and budget of the specific project to efficiently but thoroughly produce the answers our clients require. Information from these studies is useful for management, mitigation and rehabilitation activities, as well as providing a better understanding of how the environmental context affects ecosystem processes and organisms.

Here are some of the services we can provide:


  • Distribution and abundance
  • Migration and movement
  • Survival and growth
  • Spawning and adult escapement
  • Habitat use
  • Population modeling
  • Production estimates


  • Quantitative and Qualitative habitat assessments
  • Habitat mapping
  • Invertebrate sampling, monitoring, and analysis
  • Amphibian sampling and habitat studies
  • Aquatic food web analysis
