Abstract

One of Rawa Besar Small Lake’s roles for the surrounding community is as a fishing spot. Locals would often go fishing at the edges of the small lake. The ability of a lake to provide fishes to catch is partly due to the availability of food in the ecosystem, most importantly the microalgae community as the main producer in the freshwater food web. This concept is used in aquaculture as a way to obtain a more sustainable ingredient for feedant. Microalgae are used for aquaculture feedant due to its nutritional value. However, it is important to assess the safety and suitability of microalgae used for feedant due to the difference in toxicity and nutritional value of various microalgae species. Observation of the water samples taken from Rawa Besar Small Lake shown that potential microalgae species like Kirchneriella and Arthrospira lives in Rawa Besar Small Lake. However, toxic microalgae species like Planktothrix has been found in said water sample as well. Isolation of potential species is necessary in order to produce a healthy feedant for aquaculture out of Rawa Besar Small Lake’s microalgae community
