Pond Boss Forums AQUATIC VEGETATION Balance of plants in the environment Winter FA ?

Winter or cold water FA can be due to several cold water adapted species similar to there is not just one specie of trout. In addition there are several other cold water adapted fish similar to various types of cold water algae - various diverse types. We should be careful not to generalize too much and apply one "rule" with cold water algae.

My guess and just a guess without seeing and analyzing, is the FA during the cold season was thriving on the nutrients oozing from the sediments plus maybe some mineral stimulus from the well. The green color bloom may have suppressed light to the FA which it didn't 'like'. Snow and ice dropped the temp and the green water bloom died back. Added rain probably added nutrients with the runoff and adjusted the nutrient balance in the pond. As the water warms green plankton continues to grow and it is absorbing the nutrients. If results of feeding the fish provides the right nutrient inputs then the bloom will continue. If not the right nutrients are provided the FA may return as a different species adapted to warmer water.
