Estimating the size of fish consumed by double-crested cormorants: Considerations for better understanding cormorant-fish interactions Estimating the size of fish consumed by double-crested cormorants: Considerations for better understanding cormorant-fish interactions
We measured 926 smallmouth bass (Micropterus dolomieu), 6,935 yellow perch (Perca flavescens), 6,416 rock bass (Ambloplites rupestris), and 4,852 pumpkinseed (Lepomis gibbosus) otoliths recovered from double-crested cormorant (Phalacrocorax auritus) pellets to determine the sizes (total lengths) of these fish consumed by cormorants. Otoliths were recovered from cormorant pellets...

A broadscale fish-habitat model development process: Genesee Basin, New York A broadscale fish-habitat model development process: Genesee Basin, New York
We describe a methodology for developing species-habitat models using available fish and stream habitat data from New York State, focusing on the Genesee basin. Electrofishing data from the New York Department of Environmental Conservation were standardized and used for model development and testing. Four types of predictive models (multiple linear regression, stepwise multiple linear...

Application of neural networks to prediction of fish diversity and salmonid production in the Lake Ontario basin Application of neural networks to prediction of fish diversity and salmonid production in the Lake Ontario basin
Diversity and fish productivity are important measures of the health and status of aquatic systems. Being able to predict the values of these indices as a function of environmental variables would be valuable to management. Diversity and productivity have been related to environmental conditions by multiple linear regression and discriminant analysis, but such methods have several...

Juvenile rainbow trout production in New York tributaries of Lake Ontario: implications for Atlantic salmon restoration Juvenile rainbow trout production in New York tributaries of Lake Ontario: implications for Atlantic salmon restoration
Three Pacific salmonid species Onchorynchus spp. have replaced the extirpated Atlantic salmon Salmo salar as the main migratory salmonid in the Lake Ontario drainage. One of those species, the nonnative rainbow trout O. mykiss, has become widely distributed within the historical Atlantic salmon habitat, occupying an ecological niche similar to that of juvenile Atlantic salmon...

A novel approach to fitting the von Bertalanffy relationship to a mixed stock of Atlantic sturgeon harvested off the New Jersey Coast A novel approach to fitting the von Bertalanffy relationship to a mixed stock of Atlantic sturgeon harvested off the New Jersey Coast
We examined the growth characteristics of 303 Atlantic sturgeon, Acipenser oxyrinchus, caught in the commercial fishery off the New Jersey coast from 1992 to 1994 (fork length range: 93–219 cm). Sections taken from the leading pectoral fin ray were used to age each sturgeon. Ages ranged from 5–26 years. Von Bertalanffy growth models for males and females fit well, but test statistics (t...

An enhanced cluster analysis program with bootstrap significance testing for ecological community analysis An enhanced cluster analysis program with bootstrap significance testing for ecological community analysis
The biosphere is filled with complex living patterns and important questions about biodiversity and community and ecosystem ecology are concerned with structure and function of multispecies systems that are responsible for those patterns. Cluster analysis identifies discrete groups within multivariate data and is an effective method of coping with these complexities, but often suffers...
