The sponge is an invertebrate animal from phylum porifera that lives permanently and filters out what is in the water column. The sponge has various forms of growth, including massive, branching, and submissive. Each form of growth is indicated to have different filtering abilities, so this research needs to be done. This study aims to determine whether the ability to filter (biofilter) Turbidity and Total Suspended Solid sponge depends on the form of growth (Massive, Submassive, and Branching). This research was conducted from September to October 2016. Taking sponges in the waters of Barranglompo Island, testing was carried out at the Hatchery Marine Station at Hasanuddin University, Barranglompo Island and measurements of water quality parameters were carried out at the Chemical Oceanography Laboratory, Department of Marine Sciences, Faculty of Marine and Fisheries, Hasanuddin University. The acclimatization process needs to be done to adapt the sponge before being given treatment. Each aquarium is filled with seawater that has been mixed with sediments as much as 0.17 mg/l. Then each form of sponge growth is put into an aquarium with the same body volume of 500 cm3 and sees the ability to filter it for 10 hours and 24 hours. After that, water samples were taken at each aquarium to measure turbidity parameters, Total Suspended Solid, and Total Organic Materials. The results showed that at 10 hours and 24 hours the sponge with submassive growth forms filtered more particles in the water column than massive and branching growth forms, while sponge with branching growth forms run into stress and death after filtering for 24 hours.Keywords: growth pattern, biofilter, sediment, sponge.

Mangrove reforestation is often carried out in various regions or regions, but information about the relationship of environmental factors and the distribution of fauna associations is still very minimal. The Principal Component Analysis (PCA) study on the correlation of environmental factors and the spatial distribution of the molusks community in the Seribu Islands mangrove reforestation area was conducted in March 2014 with the aim of analyzing environmental factors for the diversity and presence of the molusks. Environmental factors are measured insecurely, while the moluccan community is collected by making line transects and plots measuring 10 x 10 m2 and in the size of 10 x 10 m2, a small plot of 1 x 1 m2 is made. The results of the study show that environmental factors are not so different between stations and do not exceed the quality standard for the lives of 4 species of mollusks, where the parameters of aquatic pH are the environmental factors that most influence their distribution.Keywords: environmental factors, distribution, mollusks community, mangrove reforestation, Seribu Islands

The skipjack tuna (Katsuwonus pelamis) resource in Bone bay has long been exploited, but information about the sustainable potential of this fish resource in Bone bay waters is still very limited. The aim of this research is to estimate potential of fish resources that include catch per unit effort (CPUE ), the maximum sustainable yield (MSY), optimum effort, exploitation rate and total allowable catch (TAC) of skipjack tuna in the waters of Bone bay. This study uses time series data, namely annual data from the fisheries statistics report at Marine and Fisheries Service, South Sulawesi Province from 2006-2015. The method used to estimate the potential of fish resources in this study is the surplus production method with the Schaefer model. The results showed that the average production and standard efforts in the 10-year period were 14689.7 tons and 914 standard units respectively. The estimation results obtained MSY and optimum effort per year are 22561.4 tons and 1730 standard units, and allowed catches (TAC) of 18049.2 tons per year. The level of exploitation of skipjack tuna resources in the waters of Bone Bay does not over exploited every year except in 2017.Keywords: potential of fish resources, skipjack tuna (Katsuwonus pelamis), MSY, TAC, Bone bay

Aquatic plants are an indicator of the fertility of an aquatic region. The waters of Lake Tempe are the largest waters of the lake area in South Sulawesi. Lake Tempe is located in the western part of Wajo District, precisely in Tempe District, about 7 km from Sengkang City towards the banks of the Walanae River in southern Sulawesi. The area is about 13,000 ha with a maximum depth of 5.5 m and can reach more than 30,000 ha during floods, and during the dry season, the inundation area reaches only 1,000 ha with a maximum depth of 1 m, located above the continental and Australian and Asian plates. This lake is one of the tectonic lakes in Indonesia. Every year silting the lake occurs. The Tempe hydro vegetation and eco-physical research were carried out in October 2017. The purpose of this study was to record aquatic plant species that live in Tempe Lake and observe ecological changes and physical properties of Lake Tempe. Aquatic plants are expected to be able to filter lake water. The results obtained are physical conditions of sharp-smelling water, unpleasant taste, dark brown, and cloudy color. Chemical indicators of NH3-N waters (0.2976-0.0634), PO4-P (0.0172-0.0844) NO2-N (undetectable), NO3-N (1.7131-1.9335), Sulphate (27.761900 - 37.047620), DO (6.88-7.18) and pH (7.88-8.02). There are 14 species of aquatic plants found in these waters. The most dominant species is water hyacinth. In the case of Tempe lake water vegetation results in siltation of the lake area.Keywords: Aquatic plant, Biodiversity, Species, Tempe lake,

The consequence of super intensive shrimp farming is an increase in aquaculture waste and disease transmission. Vibrio sp. Bacteria is a disease-causing agent in shrimp larvae when the shrimp is in a state of stress and weakness, and can cause death. The application of probiotics, namely beneficial microorganisms can degrade organic matter, reduce disease, and help accelerate the process of nutrient cycles as a consequence of super intensive shrimp farming. Commercial probiotics currently available are a mixture of several types of beneficial microorganisms, namely Bacillus sp., Pseudomonas sp., Nitrosomonas sp., Aerobacter sp., and Nitrobacter sp. The purpose of this study was to evaluate the use of probiotics with different time intervals to produce a decrease in the population of Vibrio sp. The research method applied was the treatment of commercial probiotics at different intervals of three, five, and seven days and without the administration of probiotics as controls. Furthermore, the bacterial population was calculated by total plate count (TPC). The results showed that the administration of probiotics had a significant effect on the decrease in the population of Vibrio sp. Provision of probiotics three days apart showed a decrease in the number of bacterial populations that were significantly different from the controls, but the same as the administration of intervals of five and seven days. The decrease in the number of bacterial populations in the treatment interval of three, five, and seven days in a row is 0.05 x , 0.41 x , and 0.61 x CFU / ml. This study recommends that the use of commercial probiotics intervals of seven days for super intensive vaname shrimp farming. The use of probiotics for three days indicates an impact on the increase in expenditure costs for probiotics. Commercial probiotic studies modified with natural microorganisms are thought to be able to streamline the operational costs of shrimp farming.Keywords: Vibrio sp. bacteria, probiotics, vaname shrimp, super intensive cultivation

This study was aimed to identify the potential use of active compounds extracted from Staurogyne sp as an antibacterial agent to control disease-causing bacteria in fish. Staurogyne sp, an aquatic plant collected from Bantimurung, South Sulawesi were subjected to allelochemical compound. Plant extracts were tested to five bacteria including four types of bacterial pathogen, such as Aeromonas hydrophilla, Edwardsiella ictaluri, Streptococcus agalactiae, and Flavobacterium columnare, and one bacterial sensing quoroum, Chromobacterium violaceum. Based on phytochemical analysis, Staurogyne’s extracts derived from both stem and root contained flavonoids, phenols, and antioxidants compounds with the concentration of 0.018 mgQE/g, 0.3471 mgGAE/g, and 1004,391 IC50 µg/mL, respectively. In addition, Staurogyne plant extracts derived from both their stem and root has also produced both saponins and glycosides compounds. Plant extracts derived from Staurogyne’s leaves revealed three major chemical compounds such as flavonoids (0.77 mgQE/g), phenol (0.0629 mgGAE/g), and glycosides (+). However, no antioxidants and saponin compounds were detected. Applying plant extracts as an antibacterial on five disease-causing bacteria causing diseases in aquaculture, such as Aeromonas Hydrophilla, Edwardsiella ictaluri, Streptococcus agalactiae, Flavobacterium columnare, and Chromobacterium violaceum bacterials revealed that at concentration of 0.1 g the Staurogyne sp extracts did not influence all the bacterials growth. However, by application of plant extract at concentration of 0.2 g on the growth media,three out of 5 tested bacterials (Aeromonas hydrophilla, Edwardsiella ictaluri, and Streptococcus agalactiae) showed intermediate inhibition responses on bacterial growth. The growth of remaining two bacterials pathogen, Flavobacterium columnare and Chromobacterium violaceum at 0.2 g plant extract of Staurogyne sp was not affected. This study revealed that the use of active compound derived from Staurogyne sp would be potential to be used in inhibiting disease-causing bacterial in fish in future. However, optimum concentration of the plant extracts, in particular on the inhibition of the growth of disease-causing bacteria in fish is still needed to adjust.Key words: Antibacterial, aquatic plant, Staurogyne sp, fish disease
