Abstract

Disturbance of water environment due to organic enrichment caused by farming activities may result in the reduction of water quality and sediments. This study was conducted to determine the condition of the water and sediments in the area of aquaculture in ponds system compared to the adjacent coastal area of industrial activities. Water qualities observed were the temperature, DO, salinity, conductivity, turbidity and pH. Sediment characteristics measured were sediment grain size and organic matter content contained in the sediments. From the research, the temperature values obtained ranged 28.7-32.9°C, DO 3.63 to 6.4 mg/l, pH 4.31 to 6.27, salinity 4.6 to 33 ‰, conductivity 8.5- 50.2 ms/cm, turbidity 73-535 NTU. The substrate grain analysis showed at the fish farm area in pond systems was dominated by silt 71.70% and clay 16.71%. In the coastal area adjacent to the industrial activities, 93.38% substrate was dominated by sand. Analysis of organic matter content in the pond systems exhibited the highest ranged between 0.72% -1.16% for nitrogen and 3.20%-10.35% for carbon. The differences in the composition of the substrate and the organic material can be caused by hydrographic conditions, especially strong/weak water currents, the accumulation of litter originating from the decomposition of leaves of mangrove, enrichment of nutrients during the decomposition of litter and aquaculture activities and industries.

Abstract

The increase of fishery production nationally and internationally may impact on the potential emergence of a variety of environmental problems. The application of sustainable aquaculture is urgently needed by breeding fish for commercial purposes in a manner such that it has a minimum impact on the environment, contributing to the development of local communities and generating economic benefits. The design of the cage and farming practice in aquaculture activities are the important steps to ensure that farming activity is still observed in order to anticipate the risk of organic enrichment caused by the activities. The application of Integrated Multi-Trophic Aquaculture  (IMTA) on the Stratified Double Floating Net Cage  (SDFNC) integrated with biomonitoring are an appropriate solution to the ongoing productive farming practices. IMTA is an aquaculture practice using more than one species of biotas which have ecologically mutual relationship as a part of the food chain in the area at the same time. The application of IMTA allows farmers to get several aquaculture products in the same area without increasing the horizontal area of the farms. At first, the SDFNC has been applied for farming Cyprinus carpio and Tilapia niloticus as polyculture system in freshwater ecosystem of Rawapening Lake, Central Java. Its operation has been able to increase the production capacity of at least 75% of conventional cages. The application of SDFNC-IMTA using milkfish (Chanos Chanos), seaweed (Kappaphycus alvarezii), and white shrimp (Litopenaeus vannamei) has been able to minimize the impact and maintain the water ecosystem in the Gulf Awerange, South Sulawesi.

Abstract

Fish farming using floating cage has been conducted for a long time in Indonesia. Despite the benefits of aquaculture to meet the needs of the human protein, aquaculture has potential impact on the aquatic environment, especially due to the impact  of  organic  enrichment.  This  study aims  to  determine  the  relationship  of  water  physical-chemical  on  the abundance of mollusks as a biological agent to determine the level of environmental disturbance. This research was conducted in the waters of the Awerange Gulf, South Sulawesi. Mollusks samples were taken from two stations, namely the reference area and polyculture cage area with twice the sampling time and three   replicates. Abiotic and biotic relationships conducted using multivariate approach (Principal Component Analysis / PCA, BIO-ENV) using Eucladian Distance matrix. Based on the results, there were 15 species consisting of 14 families and 2 classes (gastropods and bivalves). Families were most prevalent in both sites was Turritellidae. In general, water quality in the Awerange Gulf is considered normal at both locations. Results of ordination using PCA on abiotic factors indicated that the stations between reference area and polyculture cage area are clustered, implying the difference of both sites. BIO-ENV analysis results indicates that the abiotic factors that most influence the distribution and abundance of molluscs in the Awerange Gulf were DO, Carbon and Nitrogen contain (r = 0.457; BIO-ENV). Keywords : Mollusk, Polyculture Cage, Awerange Gulf, Abiotic Component
