Abstract

The primary sources of organic waste in prawn ponds include feed waste from the farming process as well as ongoing metabolic activity, such as the production of urine and faeces. The increase in organic waste has an impact on reducing the water quality, one of the solutions is by implementing phytoremediation with seaweed. This research aimed to analyzed the growth and ability of seaweed Sargassum sp., Gracillaria sp., and Caulerpa sp. as phytoremediation agents to reduce organic matter in waters. This research was conducted for 68 days and used an experimental method with a completely randomized design (CRD) with 4 treatments and 3 replications. The treatment are A Sargassum sp., B Gracillaria sp., C Caulerpa sp. and D control. The results indicated that treatment C tended to decrease total organic matter (TOM) and sediment organic matter by 123.74 mg/l and 1.37%, respectively. The result also revealed that Caulerpa sp. the most effective seaweed to be used as phytoremediation organic materials in tiger shrimp farms compared to the two other seaweed species (i.e., Gracillaria sp. and Sargassum sp.). The growth of seaweed showed that there was a significant difference in specific growth of seaweed. The best specific growth rate value in treatment C was 1.37 ± 0.1%. The results of this study shown that Caulerpa sp. has more effective remediate organic matter and improve seaweed growth than Gracillaria sp. and Sargassum sp.

Abstract

Plawangan Timur Segara Anakan lagoon is known as the unique aquatic ecosystem that supports the life of aquatic organisms by providing nursery and feeding grounds. However, the Eastern Part of Segaran Anakan Lagoon is also utilized by many industrial and domestic activities that could degrade the quality and quantity of the aquatic ecosystem. This research aims to decribe the composition, diversity, and ecological niches of ichthyofauna from Eastern Segara Anakan Lagoon. Sampling was conducted on 29 June and 19 July 2023, using gillnets which have 1–2-inch mesh size. The diversity of ichthyofauna analyzed using the diversity indices while the distribution of the ichthyofauna were performed using Cannonical Correspondence Analysis (CCA). This study found 120 individuals of fish, that is comprised of 21 species, 19 families and 11 orders. The fish comprised of 18,34% adult and 81,66% juvenile. Most fishes were categorized as marine-freshwater-brackish resident and only I. japonica and S. commersoni species are true marine fishes. The diversity indices showed that Kali Panas station have the highest diversity indices and the lowest indices value were in Ujung Galang station. CCA showed that most fishes that are categorized as Marine, Marine-Reef-associated, and Marine, Brackish, Reef-Associated resident were found in high salinity waters.
