, 2010). Fisheries with more than 50% of the catch estimated as IUU include shark, tuna, and anchovy (see Table 1 in Varkey et al., 2010), with IUU fisheries valued at USD $40 million in 2006. Anchovy are caught using lift nets (bagan) and in some cases mesh sizes

are so fine that the catch consists primarily of juveniles. This unregulated fishery produces hundreds of tonnes of fish which are either dried for human consumption or used as live bait for tuna fisheries. A study of the lift net fishery in one bay in Raja Ampat estimated that 2493–4468 tonnes of anchovy were caught each year with a total value of USD $1.2–2.1 million ( Bailey et al., 2008). These types of operations are common throughout Indonesia and are largely operated by outside ZD1839 in vivo fishers from Sulawesi or other parts of Indonesia. Other than the loss of potential revenue for the local government, the effects of unregulated harvest of the base of the food chain is likely to impact not only the productivity of larger prey species such as tuna but also endangered species such as baleen whales that Selleckchem Alectinib frequent

the area. Overall, there is little information on current fisheries trends in the BHS with almost all fisheries operating in the absence of critical information on stocks, few management regulations and little or sporadic enforcement. Pelagic fisheries in northern BHS and shrimp fisheries in southern BHS are already considered over exploited by the Indonesian government. While there is a growing interest in applying ecosystem based approaches to fisheries management in Indonesia, the concept is still relatively new with no examples of how to best apply this model. With the exception

of MPAs in the BHS where there are some efforts to manage local and commercial fisheries (see Section 6), coordinated efforts to manage coastal or pelagic fisheries sustainably are MYO10 largely absent in the region. Though there are some encouraging signs of governmental interest in improving fisheries management, in the absence of critical baseline information on fish, shark and invertebrate stocks and poor enforcement of existing regulations, fisheries stocks will likely continue to decline in the BHS. The past 10 years have seen a dramatic expansion of marine tourism in the BHS as the region has developed a reputation as one of the top diving destinations on the planet (Jones et al., 2011). In Raja Ampat alone, the industry has expanded from a single diving resort and one live-aboard dive vessel visiting the area in 2001 (with a combined total of approximately 300 guests/year) to 8 resorts and over 40 dive live-aboard boats servicing over 6400 guests per year in 2011.
