Indonesia is one of country that does highest shark fish ing in the world. Shark fishing in Indonesia for the period 2000-2010 produced an average of 106 . 288 tonnes / year. As a follow up of this and maintain the balance of the ecosystem, it is necessary monitoring. The study was aim ed to determine the species composition, production of shark catches, and the coordinates of the fish catching . The study was conducted in April-May 2016 at the Cilacap Oceans Fishing Port , Central Java. Th is research used descriptive method and s ampling was done by a purposive sampling. T here were 9 species of shark were landed , there are pelagic thresher (Alopias pelagicus), big-eyed thresher (Alopias superciliosus), s ilky shark (Carcharinus falciformis), blue shark (Prionace glauca), longfin mako (Isurus paucus), sh ortfin mako (Isurus oxyrinchus), tiger shark (Galeocerdo cuvier ), sand bar shark (Carcharhius plumbeus), and scalloped hammerhead shark (Sphyrna lewini). The highest production was big-eyed thresher with total production of 1 1.257 kg. Blue s hark and pelagic thresher total weight reached 6 . 625 kg and 7.055 kg, while the scalloped hammerhead shark has a total weight of 392 kg.

Shark fishing in Indonesia for the period 2000-2010 produced an average of 106.288 tonnes / year. As a follow up of this and maintain the balance of the ecosystem, it is necessary monitoring. The study was aimed to determine the species composition, production of shark catches, and the coordinates of the fish catching. The study was conducted in April-May 2016 at the Cilacap Oceans Fishing Port, Central Java. This research used descriptive method and sampling was done by a purposive sampling. There were 9 species of shark were landed, there are pelagic thresher (Alopias pelagicus), big-eyed thresher (Alopias superciliosus), silky shark (Carcharinus falciformis), blue shark (Prionace glauca), longfin mako (Isurus paucus), shortfin mako (Isurus oxyrinchus), tiger shark (Galeocerdo cuvier), sandbar shark (Carcharhius plumbeus), and scalloped hammerhead shark (Sphyrna lewini). The highest production was big-eyed thresher with total production of 11.257 kg. Blue shark and pelagic thresher total weight reached 6.625 kg and 7.055 kg, while the scalloped hammerhead shark has a total weight of 392 kg. Temporally capture production trends tended to increase from year 2012 to 2015. Distribution of fishing coordinate point was in the range of latitude 7048'58,0"until 8005'42,9" and the longitude 109005'07,1"until 109045'03,5" for longline fishing gear. For gillnet fishing gear was in the range of latitude 7044'51,8"until 7049'09,0" and longitude 109005'12,1"until 109011'20,4". Overall distribution of both types of fishing gear were between latitude 7049'27,0"until 8002'43,1" and longitude 109007'06,4"until 109045'03,5" which is part of the southern part of Cilacap waters.
