Development of an adaptive monitoring framework for long‐term programs: An example using indicators of fish health
Detecting unwanted changes associated with localized human activities in aquatic ecosystems requires defining the value of an indicator expected at a site in the absence of development. Ideally, adequate and comparable baseline data will be collected at an exposure location prior to that development, but this is rarely done. Instead, comparisons are made using various designs to overcome the ...

Prevent Fish Kill in the Spring
Pond Deicing Can Help Prevent Fish Kill Keeping the pond open will help keep oxygen in the water, attract water fowl and help prevent fish kills in the spring. The most common cause of fish kills is suffocation due to lack of dissolved oxygen. Most dissolved oxygen is produced by algae and aquatic plants through photosynthesis. A lesser but also important source of oxygen in water is diffusion ...
