Abstract:
The purpose of our paper is to investigate why brown trout are being introduced into the Hudson River when the native species, brown trout is present. Out study began when we went to the Cold Spring's hatchery where we stripped Brown trout eggs. We brought the eggs to our tank in our classroom where we planned to raise them. We monitored the tank daily and removed dead eggs to prevent disease. Once four weeks passed the eggs quickly began to hatch what remained of their egg shell behind in the incubators. This caused the spread of fungus which took most of our attention to clean. When the trout became larger and we were able to swim we released them into the tank where they could adapt to the conditions of a larger environment. We will present some of the challenges we encountered in this paper. We conducted chemical testing for ammonia and pH on the water before and after water changes to ensure a controlled environment that was optimal for survival; Environmental conditions and mortality were recorded daily.

The information gathered by the previous team helped us better understand the activities of our brook Trout and draw conclusions of our own. Not only did we look to last year's team's results for comparison, but we also researched background information on the two species in their natural habitat so that a comparison could be made comparing the two species. Our goal is to understand why brown trout have been introduced into the Hudson River.
Background:
The Cold Spring's hatchery is responsible for the many trout that have survived into adulthood. It is here that trout are studied and raised to preserve trout in the Hudson River. When at the hatchery,
