Abstract

Initial visual assessments Wide range in the quality of fit between features in NHD and these new image sources. No statistical analysis has been performed to actually quantify accuracy Determining absolute accuracy is cost prohibitive (must collect independent, well defined test points) Quantitative analysis of relative positional error is feasible.

Freshwater and diadromous Fishes of Puerto Rico

Freshwater and Diadromous Fishes of Puerto Rico describes the diversity of fishes in Puerto Rico’s freshwater environments and provides information on the history of research, management and conservation, and culture of fish and fisheries in Puerto Rico. This book’s catalog of fishes guides the reader in the identification of more than 50 native and nonnative species of fish from 22 families that occur in Puerto Rico’s freshwater lagoons, rivers, streams, and reservoirs. Each species account includes a map of known occurrences, and a description of each species’ morphological characteristics, biology, and distribution. Freshwater and Diadromous Fishes of Puerto Rico is the result of decades of scientific research; however, it is intended to be accessible and useful to readers with a variety of backgrounds, including scientists, students, and outdoor enthusiasts such as recreational anglers and freshwater snorkelers. Conservation and management are underlying themes of Freshwater and Diadromous Fishes of Puerto Rico . Though the main goal of this book is to be a resource for the identification of Puerto Rico’s freshwater fishes, and on their biology and ecology, it is also intended to increase awareness of threats to these fishes and their value to people and ecosystems.
