Fish+Grassland
(Diadromous, Freshwater, and Saltwater) - Fish, aquatic vertebrates which are covered in scales and equipped with fins (paired and unpaired), are found in all types of aquatic environments ranging from freshwater to saltwater. Diadromous fish are those that travel between fresh and saltwater (Pacific salmon, for example, which is an anadromous fish that breeds in freshwater but lives in the sea, mostly). Monitoring the abundances of the prey fish populations is critical to managing the lake ecosystem. Presently, salmonines are stocked into the lake to supplement and sustain their populations within the lake.

Black Salty: Implications of survival of non-native live salt-water bait
The black salty is simply a variety of goldfish. Goldfish are non-native fishes from Asia that can disrupt natural habitats by interfering with feeding and reproduction of native fishes. Non-native fishes may compete with the young of game species that use estuaries as nurseries. Once a population of non-native fish is introduced and reproducing in a natural habitat, they are very difficult or impossible to eliminate.
