Human population growth and rising sea levels have led to dramatic changes in ecosystems at the land-water interface. Forests have been replaced with housing, agriculture, and industries that increase nutrient, sediment, and contaminant loads to adjacent waters.
This site includes links to my research activities in Marine Biology and Ichthyology. It includes extensive data on fish sounds and fish diets.
I'm currently conducting studies on soniferous behavior of fishes and invertebrates which address the role of vocal communication in reproductive and predator avoidance behaviors, and that attempt to address habitat use questions e.
One of my major research activities is in the rapidly developing field of passive acoustics, where I have been working to promote its Estuarine ecology to fisheries science. Recently I have begun work on the soundscape of freshwater habitats, particularly in the Amazon River, Kennebec River, and Lake Champlain.
Abstracts from many of my papers and slides from recent talks can be viewed in my online C. I've also included links to some Estuarine ecology figures and unpublished photographs from the field, as well as selections of my art, poetry, and theological writings. Two of my most popular sites are the "Fish Facts and Web links" page and the "Childrens Stories" page.
Please help support my research on fish sounds. A NON-Tax deductable contribution will be used to support purchase of equipment, software, travel, and publication of research. Table of Contents About me Curriculum Vitae - The online version of my CV contains links to papers or abstracts from many of my publications, as well as links to past seminars including talks on summer flounder, Gulf of Maine fish diets, Georges Bank guild structure, Ontogenetic shifts in predator types, estuarine habitat use patterns of marsh nekton, passive acoustics and fish sounds.
My one page resume is available in html and PDF formats. An illustrated summary of some of my research interests is available as a 1. These pages provide extensive examples of fish sounds.
You can also find brief summaries of some of my current passive acoustics research projects. Those interested in more detailed information can download published papers and reports from my CV page.
Includes a gallery of underwater fish sounds, deep sea fish sounds, sounds of the Gulf of Maine, my e-book "Listening to fish", sounds of the cusk-eel, fish songs ringtones updated ringtones!
Go to the Soniferous main page for a list of many projects and examples of fish sounds Soniferous fish ecology Research on what fish eat, estuarine habitats and fish aggregation devices Estuarine Research - These pages describe some of my past and ongoing research on estuarine fishes, essential fish habitat for estuarine fishes, and saltmarsh community structure.
Trophic Research - What do fish eat? What are the predators of a given fish or invertebrate? Find the answers here. I have conducted extensive research of marine fish food habits and include extensive tabulated data and analyses in my web page.
This include extensive summaries of the diets of NW Atlantic fishes, including over 1, pie charts and diet composition tables for over species of fish and two squids, plus tables of all predators for a given species Analyses based on data provided by the NMFS.
It also includes summaries of diet analysis for several unpublished papers. Fish Aggregation Devices FADs - These pages provide pictures and information on FAD research that I conducted some time ago, but which is still frequently requested from fishers, and resource managers around the world, especially from developing countries and subsistence fishers.
Other topics Children's Stories New for kids, I've decided to post some of the fictional and some nonfiction children's stories I've written over the years for my family. General Photographs - of myself, colleagues, and fish many more photographs under other sections. Fish facts and web links Collection of interesting fish facts compiled by Rodney Rountree, including lists of the biggest fish in the world, and links to other web pages on marine ecology, fish and fish sounds.
I've added a fun page of "find the fish" picture puzzles. Can you find the hidden fish, crabs and lobsters? My writings and art Web page with selections of my poetry, songs, art, and Christian theology writings.

I usually average visits per day on the site as a whole.Estuarine ecosystems are a key transition zone between freshwater and marine ecosystems, with particular importance to salmon recovery. The Watershed Program's estuarine research efforts range from basic food web research in the pelagic zone of Puget Sound to researching salmon and forage fish ecology in estuaries.
