Abstract

Mangrove forest is a unique natural ecosystem with high ecological value. The mangrove ecosystem is one of the areas with high productivity due to the presence of litter and litter decomposition occurs and produces detritus. This study aims to describe aquatic biota associated with the remaining stands of mangrove plants in the area of land conversion in Lino Tolonggano Village, South Banawa District, Donggala Regency, so that the surrounding community can be informed about the importance of the existence of mangrove forests. This type of research is descriptive quantitative research, with survey method with purposive sampling technique. The data obtained were analyzed using the association determination formula as well as additional posters that will be used as information material to the public regarding the existence of mangroves in the area of land conversion. The results obtained in this study indicate that the types of mangroves and associated aquatic biota are Sonneratia alba, Rhizophora mucronata and Rhizophora apiculata for the mangrove group and Nerita sp, Telescopium telescopium L, Uca sp and Periophthalmus modestus for the aquatic biota group. Data analysis showed that there were associations between plant species in the form of negative associations. This indicates that the aquatic biota found are not biota that use mangroves as a place to live.

Abstract

Plankton are organisms (animals and plants) that live floating or floating in the water column, their movement is influenced by currents. The role of plankton is very important in aquatic ecosystems, especially phytoplankton which are primary producers. This research is a quantitative descriptive study using purposive sampling method with a field and laboratory survey approach. The purpose of the study was to describe the abundance and diversity of plankton in the waters of the Tasilaha Lagoon. This research was conducted in June – July 2022. The results of the study were 31 types of plankton consisting of 17 types of phytoplankton and 14 types of zooplankton. The abundance of phytoplankton species obtained ranged from 366–5,597 cells/liter and zooplankton 623–5,515 individuals/liter. The value of the phytoplankton diversity index was 2.44–2.55 and the zooplankton ranged from 2.19–2.31.
