Reef fish resources in Palu Bay are under exploitation pressure with increasing demand of fish for human consumption. This study is aimed to analyze the reef fishes composition dan biodiversity in Palu Bay. Field survey was conducted in Palu Bay, Central Sulawesi, in June-July 2017. This research used a survey method on data collection of reef fishes in the form of visual census methods (UVS) and methods of UPT (Underwater Photo Transect). Three sampling station were chosen to represent reef fishes condition in Palu Bay. Results of research in Palu Bay, the reef fish composition dominated by major fishes (54%), then target fishes (40%) and indicator fishes (6%). The reef fish biodiversity index has an average of 2.44 with a range from 2.19 to 2.66, means that biodiversity is in moderate category.Keyword: Biodiversity, Reef Fishes, Palu Bay

Set net catch operated in Mallasoro Bay is very fluctuating. The fluctuations strongly assumed related to te current profile in that area. The objective of this study was to investigate the relationship between current profile with the set net catch. It was applied the linier regression for assessing its relationship. Data was collected for 35 days in set net fishing ground in Mallasoro Bay, Jeneponto. The results indicated that current direction and velocity play an important role in controlling set net productivity with significance value is 0,000028. By individually test shown that current velocity is the most influential that potentially reduces 7.29 units of set net catch.Keyword: set net, current, fish capture

The research aimed to sex ratio and size at first maturity of snakehead gudgeon at Bolano Sau Lake. The research was conducted at Bolano Sau Lake from August to December 2019. Snakehead gudgeon samples were obtained from the fishermen using a gillnet with a mesh size 2Â½-3Â½ inches. Sample analysis was carried out at the Water Quality Laboratory, State College of Fisheries and Marine, Palu. The difference in sex ratios of snakehead gudgeon used the Chi-square test, while the size at first maturity was estimated based on the Spearman - Karber method. Snakehead gudgeon caught on a gillnet in Bolano Sau Lake measuring 79-163 mm. The sex ratio between males and females is not balanced where males are more dominant in females. The size at first maturity was 119.19 mm. Suggestion minimum legal size > 120 mm. The use of gillnets in snakehead gudgeon fishing activities has an effect on the balance of male and females, but is very selective with size.

The reproductive nature of female tilapia (Oreochromis niloticus) results in decreased growth of 10-20% per generation which is characterized by small body size, slow growth and rapid maturation of gonads. One effort that can be done is the application of the sex reversal method by increasing the number of male fish through masculinization by utilizing coconut water as a natural ingredient for synthetic hormone replacement because it has relatively complete nutrition, especially potassium (kalium) content which reaches 312 mg/100g. This study aims to determine the effect of using coconut water with different concentrations on the percentage of male tilapia produced. This study was designed in a completely randomized design (CRD) with 4 treatments and 5 replications, treatment A (without coconut water), B (coconut water concentration 25%), C (coconut water concentration 35%) and D (coconut water concentration 45%). Data on the percentage of male sex were analyzed for variance (ANOVA) at the 95% confidence level and further tested by Duncan to see the effect between treatments. The results showed that the treatment of immersion in coconut water with different concentrations had a significant effect (<0.05) on the percentage of male sex of tilapia. The best percentage of male tilapia was immersed in coconut water with a concentration of 35% (treatment C), which was 86.87%.

Small scale capture fisheries is one of the leading sectors that drive the economy of Banggai Laut Regency. Fishing technology improved related to fishing efforts has an effect on the preservation of fish stocks resource in the area that it required management efforts. This study aims to determine the sustainability status of small scale fisheries in Banggai Laut Regency based on ecological, fishing technology, social and economic dimensions. The research was conducted from September to December 2017 in seven sub-districts in Banggai Laut Regency. In determining the sustainability status of each dimension, the Rapfish (Rapid Appraisal for Fisheries Sustainability) approach is used. Furthermore, in determining the attributes that had an influence on the sustainability performance of small scale capture fisheries, a leverage analysis is carried out. The results showed that the highest sustainability index was the economic dimension of 75.57 (good), the ecological dimension of 59.25 (good), and the lowest was the social dimension of 22.95 (very bad), the dimension of fishing technology was 22.62 (very bad). Remedial measures that must be taken to improve sustainability performance include improving law enforcement facilities and infrastructure at sea and empowering supervisory officers, limiting excessive use of FAD, providing subsidies to small scale fisheries, and regulating fishing areas between local fishermen and Andon fishermen.

Capture fisheries is one of the leading sectors that drive the economy of Banggai Laut Regency. Improved fishing technology is related to fishing efforts that will affect the sustainability of fish resource stocks in the waters of Banggai Laut Regency. This study aims to identify the rate of utilization of fish resources in an effort to develop a sustainable fisheries sector in Banggai Laut waters. The method approach used is "Surplus Production". This method serves as an estimator of the relative abundance of a fish resource in the waters of Banggai Laut Regency which is based on the catch per unit of fishing effort. The results showed that the capability of the fishing fleet in Banggai Laut Regency has not been able to reach potential fishing areas. The catch per unit effort (CPUE) of fish resources in Banggai Laut Regency still shows an increasing trend with the highest rate of increase by other fish group including crustaceans and mollusks, about 0.160 tons/unit in the 2014-2016 period. Meanwhile, the catch per unit effort of the large pelagic fish group showed an increasing trend with the lowest rate of increase, about 0.001 tons/unit in the 2014-2016 period. Therefore the utilization rate of fish resources in the waters of Banggai Laut Regency is still classified as under exploited.
