MDPI is working in 5 villages (kampung).to reach Kaimana Town from Denpasar, Bali, it can take until five flights through six airports in five different islands. To reach Arguni District, it can take around three hours trip using speedboat at least 15 HP (horsepower) engine capacities with volume of 5 GT (gross ton). The distance between Kaimana Town and Arguni District is approximately 60 km. If the monsoon comes, the speedboat sometimes cannot reach Kaimana Town, and this will force the boat to stop at Tanggaromi area which is located at the entrance of the Gulf Arguni. In this area, the waves when the windy season is not too large and is an area that can be reached by land transportation from Kaimana Town. The speedboat as main transportation mode.

Currently, there is no land transportations because of the rugged terrain and other factors such as infrastructure development.

The FAs was officially inaugurated in September 2015 by handing over establishment documents to DKP Kaimana. Currently there are 4 FAs in the Kaimana site: 1. FA Toftofu: 30 fishers. 2. FA Base Abuma: 40 fishers. 3. FA Itfunfidir: 20 fishers. 4. FA Totemasu: 47 fishers.

Life as Fisherwomen: Early Morning Activities In the night before go to sleep, they will put a net into the water in front of the village in order to catch the baitfish for mudcrab fishing. They do it by themselves or accompanied by their husband. In the morning, the first thing they do is cook for the family and eat breakfast with them. After cooking, they will check the net they put out the night before and will collect the baitfish caught in the net. Cooking is the first activity to start the day. Photo credit: MDPI

5 4. Fishing Gear: Bubu (Fish Trap) Bubu is a fishing tool largely known among fishermen, in the form of a cage shaped trap and it is a passive fishing gear. This traditional form of the fish trap can be made from rattan, wire, metal, mesh, wood or plastic that woven in such way so the target fish, once caught, are not able to get out. Baitfish are inserted inside the bubu to attract the target fish. Fisherwomen in Arguni District use bubu made from metal material. There are two shapes of bubu they use: square and butterfly. Square bubu has dimensions of 45 cm length, 30 cm width, 18 cm height and butterfly bubu has dimension of 55 cm length, 43 cm width, and 23 cm height. The Bubu is tied to 5-6 meters length of rope attached to a floating device.

On the way to the bubu point, they will leave the bubu open in order to save space in the wooden boat. They will close the bubu perfectly after they reached bubu point and then put it down into the water. To spread 14 bubu in the water, a fisherwoman needs around 2 hours to complete. The distance between two bubu points is around meters away. The next step is the waiting process. They will wait and take a rest in rumah singgah for an hour before they row the boat for around 30 minutes to the bubu points to check if there are mudcrabs caught. They will check bubu one by one by pulling it out. If there are mudcrab caught, they will take the crab using a net called tanggu to move the crab safely from bubu to the boat. Quick check will also tell them if the mudcrab has eaten all the baitfish or if there is leftover baitfish to use again for the next lowering of the bubu. The fisherwomen will immediately tie the newly caught mudcrabs using plastic rope in order to prevent the mudcrab claws from biting. To tie the mudcrab, the fisherwoman gently steps on the crabs and tie the rope around the body and the claws. They will put the mudcrab into a sack after tying it up. The skill of tying a mudcrab is a skill they learn from each other. The next activity is putting down the bubu again and repeating the fishing technique activities until 6 PM and then go back to village to sell the mudcrabs to local suppliers.

Wooden Boat Fisherwomen will put the bubu and baitfish into the small wooden boat whose length around 4 5 meters equipped with wooden oar as well. The maintenance of the boat happens approximately once in a month, a session where they will wash the wooden boat to remove moss and then they will dry it up under the sun.

Fishing Ground Fishing ground of the mudcrab fishing is around three hours rowing from the Kampung Tugarni; two hours rowing from Kampung Bayeda and an hour rowing from Kampung Moyana. The fishing ground names are Muara (Estuary) Tugarni, Muara Karora dan Muara Jarwara. The type of vegetation that dominates the habitat of the mudcrab is the nipa tree forest. Mangrove forest covers an area of 50,000 hectares that can be found along the bays and estuaries in the area. Recently, the local government developed a policy to retain 30 % of forest areas into areas designated for conservation.

10 9. Mudcrab Life Cycle Mudcrab Scylla serrata is the fishing target. In mating season, female crab carapace will be soft. Male crab will climb on top of the female for mating process. By the time the female crabs will spawn, she will find the location of the deep water to lay their eggs there. The number of eggs reaches more than 1,000,000 eggs per spawning event. By the time the eggs hatch, the juvenile crabs will be heading to the nipa and mangrove forest. On their way to nipa and mangrove forests, many crabs die because of predatory fish. Crabs that survive will undergo adolescence and adult life in the nipa and mangrove forest. At the age of approximately 6 months, these crabs become mature and will venture out in search of food until it reaches the deep water. Scylla serrata mudcrab. Photo credit: MDPI

Rumah Singgah (Transit House) After collecting mudcrabs they caught into the boat, they will go to the transit home near nipa trees to store the mudcrabs and then they will go back to fishing ground to return to fishing activities. Rumah singgah serves multiple purposes: As a mudcrab storage and as a temporary home to stay. In the middle of the day, they will take a break and have lunch in the rumah singgah. Usually they will stay in the rumah singgah for 3 nights and then they will go back to the village to sell mudcrabs to the suppliers. Rumah singgah size is around 5 meters length, 3 meters width and 3 meters height. It is made entirely from wood from the forest near the village. Their husbands will go to forest to take the materials and then they will transport it to the fishing ground using speedboat. Therefore, they only pay for the transportation (speed boat rent and fuel) and nails. A newly built Rumah singgah can survive approximately a year and then they will build a new one after a year. Ownership of the rumah singgah is varied. It can be owned by personal or a team. Some of the fisherwomen have a collaboration to make a joined rumah singgah together. In a rumah singgah, we can meet not only the fisherwomen, but sometimes we can meet their kids, their husbands and their pets. They will take their kids to fish and stay in the rumah singgah because they are still very young. Some of the husbands visit the rumah singgah to help or to accompany their wives.

14 12. Mudcrab Production Based on the data from Dinas Kelautan dan Perikanan (DKP) Kaimana, recorded production in 2014 was as much as 36 tons, while the total crab sent out from the Balai Karantina Ikan (Fish Quarantine) data showed 10% of total production or as much as 3.5 tons per year. 13. POKMASWAS (Kelompok Masyarakat Pengawas): A Community Based Surveillance POKMASWAS was developed by DKP Kaimana, Conservation International and MDPI. It was officially inaugurated in September The main function of POKMASWAS is to ensure that there is no violations in the conservation area. They also have the assignment to give counselling to community about the updated regulations. For data collection activities, they will support MDPI to ensure that the fishers fish in sustainable way, based on government regulation. POKMASWAS is equipped with speedboat. Photo credit: MDPI

Minimum Size and DKP Regulation Currently the central government has not issued a mudcrab fishery status nationally. According P4KSI (Research Centre for Fisheries Management and Conservation of Fish Resources), there has been no study from Ministry of Marine and Fisheries Affair (MMAF) on stock measurement and management of the mudcrab quota. PERATURAN MENTERI KELAUTAN DAN PERIKANAN REPUBLIK INDONESIA NOMOR 1/PERMEN-KP/2015 TENTANG PENANGKAPAN LOBSTER (Panulirus spp.), KEPITING (Scylla spp.), DAN RAJUNGAN (Portunus pelagicus spp.) stated that the mudcrab fishing can be done when the mudcrab s carapace size is above 15 centimeters and based on SURAT EDARAN MENTERI NO about additional rule for mudcrab harvest, fishermen only allowed to catch the crabs with minimum weight of 300 gram.in Kaimana, a mudcrab with 13 cm carapace length is already weighed 300 gram, so the fishermen are basically already obeyed the government s rule to catch the crabs with minimum 300 gram weight.

17 17. Data Management Committee (DMC) DMC of Kaimana Regency was developed by MDPI in collaboration with Conservation International (CI) and DKP Kaimana. The initial DMC meeting was held in October The purpose of DMC meeting is to develop a co-management forum to gather fishers, suppliers, industries, universities, NGOs and government to discuss about mudcrab fishery management in their region. 18.
