The study was conducted from January to December 2018 with main observation location was in Labuhan Lombok fishing port, West Nusa Tenggara. The results showed that the highest catch rate was obtained during April-June, followed by the frequent emergence of large yellowfin tuna (>100 cm FL). On the other hand, January-March was considered as a low season, where most of the catch was dominated by juvenile yellowfin tuna (<50 cmFL). The spatial distribution of yellowfin tuna abundance is closely related to the presence of FADs, where all fishing operations are carried out around FADs. Also, aggregation of fish was more likely influence by temporal variation rather than the quantity of FAD.

The research was conducted in Tambakbulusan village, Demak Regency with 20 fiber semi outdoor tanks. The tanks were used for the experiment without seaweed and with four densities of seaweed (50, 100, 150 and 200 g.m -2 ) using hanging rope and were co-cultivated with 80 individuals of post larva (2.0-2.9 g) monodon shrimp in 800 L brackish-water system.

This practice brings negative impacts on several aspects, including the economy. To address this problem, the Government of Indonesia established a special Task Force to Combat Illegal Fishing, which later  is known as Task Force 115, through a Presidential Regulation Number 115 of 2015. Task Force 115 was formed with a mandate to execute law enforcement operations to combat illegal fishing.  In general, the existence of Task Force 115 brings favourable impacts to the economy, especially from the fisheries sector. It should be noted that, because Task Force 115’s main tasks are enforcement related, the impacts to the economy are not direct. The purpose of this study was to analyse the role of the Task Force 115 in IUU fishing eradication activities that occur in the jurisdictional areas of the  Republic of Indonesia in terms of the economic fisheries. Efforts of combating illegal fishing does not necessarily generate an increase in fisheries GDP, tax income and exports. Instead, those positive impacts are attributed to a set of policies imposed by the Ministry of Marine Affairs and Fisheries since 2014, which oriented to the responsible and sustainable fisheries. The establishment of Task Force 115 was part of that. Task Force 115’s works created deterrence and triggered compliance of fisheries business actors with the prevailing laws and regulations. Compliance eventually brings positive impacts on the economy. In 2015, growth of fisheries GDP, which amounted to 8,37%, surpassed national GDP of 4.79%.
