Interaction between introduced trout and larval salamanders (Ambystoma macrodactylum) in high-elevation lakes

Article Abstract:

Effects of introduced trout and physicochemical factors on larvae of the long-toed salamander (Ambystoma macrodactylum) have been investigated. A. macrocrdactylum larvae are the main vertebrate predator in high-elevation, naturally fishless lakes in the North Cascades National Park Service Complex in Washington. Factors affecting population densities of the larval salamander include Kjeldahl-N concentration, lake elevation, and Crustacean zooplankton. In lakes stocked with trout, the reproductive status of trout affected population densities of larval salamander.

An evaluation of restoration efforts in fishless lakes stocked with exotic trout

Article Abstract:

Research indicates that fish removal from naturally fishless lakes may not be sufficient to restore lakes to their predisturbance state. Studies conducted on lakes in Mt. Rainier National Park, WA, show that even 20 to 30 years after fish removal, diatom communities have not returned to population levels observed prior to the lakes having been stocked with species of trout.

Effects of Widespread Fish Introductions on Paedomorphic Newts in Europe

Article Abstract:

Research on lakes and ponds in selected European sites shows that fish stocking has a distinct, negative impact on paedomorphic newt populations, including declines and a decrease in metamorphs, and that conservation efforts are required to prevent their extinction.
