Abstract
Controlled release fertilizer compositions which release fertilizer at a controlled rate over an extended period of time are employed in aquaculture treatment methods whereby nutrients are efficiently and effectively released into closed aquatic ecosystems such as ponds, lakes, watersheds and other aqueous environments over a period of time in order to enhance the growth of phytoplanktonic algae populations in the water and to thereby promote marine life populations.
