Impacts of Golden Alga Prymnesium parvum on Fish Populations in Reservoirs of the Upper Colorado River and Brazos River Basins, Texas


This publication is a product from the 2009 project "Modeling and Projecting the Influence of Climate Change on Texas Surface Waters and their Aquatic Biotic Communities". Abstract: Several reservoirs in the upper Colorado River and Brazos River basins in Texas have experienced toxic blooms of golden alga Prymnesium parvum and associated fish kills since 2001. There is a paucity of information, however, regarding the population-level effects of such kills in large reservoirs, species-specific resistance to or recovery from kills, or potential differences in the patterns of impacts among basins. We used multiple before–after, control–impact analysis to determine whether repeated golden alga blooms have led to declines in the relative [...]
