The proliferation of janitor fish is an alarming issue in Laguna de Bay. Two species of janitor fish (Pterygoplichthys pardalis and Pterygoplichthys disjuntivus ) which initially thrive in the lake due to escapement from ponds had an impact on the environment which favored their establishment. The high load of nutrients and expanded agricultural and livestock production had favored the growth and proliferation of this species.

Eutrophication of Lake Amatitlan in Guatemala – Video
Credit video: Manuel Cano Alfaro (Guatemala)
Review: Abdel Rahman El Gamal
This video shows the algal scum on the water surface of Lake Amatitlan in Guatemala. The lake receives great amount of the sewage from Guatemala City through different tributaries turning into a completely eutrophic body of water. The heavy nutrients load as represented in phosphorus and nitrogen has led to the proliferation of micro algae known as microcystin which has negatively affected the oxygen levels in the lake’s surface.
The on-going aeration of the lake targeted to alleviate some eutrophication effects. Also, the introduction of water hyacinth aimed to utilize the significant ability of this weedy plant in removing nutrients (mainly nitrogen and phosphorus) from the water.
