The University of Exeter study has been published in The Journal of Nutrition and is the first of its kind to demonstrate that the ingestion of two of the most commercially available algal species are rich in protein which supports muscle remodeling in young healthy adults.

It is a complicated topic, pest management strategies can vary. A lot of the time it is site and organism specific as far as what you'd end up with, certain species can be susceptible to different infestations. So many invasive organisms require different cures, these can include chemicals, fungicides, filtration, but these kinds of contamination events are somewhat expected after enough time, so as long as the same issue isn't recurring too frequently, the economic strategy is to just reboot the pond after a clean.

Typically, the strategy is to outcompete what you may get contaminated with. Ideally your crop is a high productivity strain of algae (much more productive than things originating outside the pond), and as long as the algae exhibit faster growth rates, the invasive species doesn't have an opportunity to take off as the desired algae will continue to take the majority of nutrients.

If you get something toxic in there, it's gotta be dealt with accutely based on the critter, but other preventative strategies like inlet media filtration/heating, crop rotation, and organism population monitoring can help mitigate these things from starting up. A good review can be found here.
