ABSTRACTFilter net has a mesh size in small size pockets of the net. This allows filter net has the potential to be non-selective fishing gear about the fish size and the target species catch. If the fishing gear allowed, hence its existence will ultimately have a negative impact on the sustainability of fisheries resources, especially in coastal waters. The objective of this research is to calculate compositions and proportions of the main catch, bycatch and discard of the filter net. It is expected by knowingÂ the composition and proportion of the main catch, bycatch and discard can provide an overviewÂ of the pressure on the stock and sustainability of fisheries resources inÂ waters where it is operated. This research was used survey method. A series of survey activities was conducted directly in the field to identify and count species of filter netâ€˜s fishing catches. Based on the main catch, bycatch and discard of the filter net, it shows that Sergetes similis is the dominant species caught bythe filter net(98.455%).Â The main catch for Escualosa thoracata reaches 1.354%. Besides, the main catches that were caught were Metapenaus monocerus, Parapenaeopsis sp, Panulirus sp and Paneeus monodon with the catch percentage ranging from 0.011 to 0.024%. Percentage of by-catches reached 0.04-0.00004% of the 24 species caught and the catch removed was around 0.001-0.0005% of the 3 species caught.Keywords: bycatch, discard, filter net, fisheries resources, main catchABSTRAKGombang memiliki ukuran mata jaring pada kantong berukuran kecil. Hal ini memungkinkan alat tangkap gombang berpotensi menjadi alat tangkap yang tidak selektif terhadap ukuran ikan dan jenis yang menjadi sasaran tangkapannya. Apabila alat tangkap ini dibiarkan, maka keberadaannya pada akhirnya akan memberikan dampak yang negatif terhadap keberlanjutan sumberdaya ikan terutama di perairan pantai. Tujuan penelitian ini adalah untuk menghitung komposisi dan proporsi hasil tangkapan utama (main catch), hasil tangkapan sampingan (bycatch) dan hasil tangkapan yang dibuang (discard).Diharapkan dengan mengetahui komposisi dan proporsi hasil tangkapan utama, sampingan dan yang dibuang dapat memberikan gambaran tentang tekanan terhadap stok dan kelestarian sumberdaya perikanan di perairan dimana gombang dioperasikan.Metode yang digunakan dalam penelitian ini adalah metode survei.Serangkaian aktivitas survei dilakukan secara langsung di lapang untuk mengidentifikasi dan menghitung jenis spesies yang tertangkap oleh alat tangkap gombang.Berdasarkan persentase hasil tangkapan utama, sampingan dan buangan per jenis, menunjukkanÂ Sergetes similis merupakan spesies yang dominan tertangkap oleh alat tangkap gombang (98,455%).

Tanjung Jabung Barat Regency has a great potential for mantis shrimp (Harpiosquilla raphidea) resources. This commodity is highly valued, as its price range from Rp. 143,600 to 180,700 for each individual. Annually, the total catches constitute 125,000-225,000 individuals, which become one of export commodities to various countries. In Tanjung Jabung barat, the mantis shrimp has been caught by using gillnet with mesh size of 10 cm. Unfortunately, mantis shrimp fishing deal with a significant number of bycatch and discards, which potentially have negative impact on sustainable fisheries resources. Therefore, the purposes of this study was to emphasis on sustainable fishing effort of mantis shrimp and identify the composition and proportion of bycatch and discards. A series of surveys was conducted for collecting the amount of species caught by gillnet during mantis shrimp fishing operation. The result shows that the bycatch and discards dominated the total catches making up to 54.99% (7 species) and 22.69% (7 species) respectively. Mean while, the total of fishing catches for mantis shrimp was 22.32%.Keywords: bycatch, discards, gillnet, mantis shrimp (Harpiosquilla raphidea)

Based on the research that has been carried out, the extent of potential damage to marine waters due to the operation of the sondong is directly proportional to the length of the operation time, the size of the sondong, the sweep length and the number of back and forth fishing gear. The longer the operating time, the larger the fishing gear size, the wider the sweep area and the greater the number of fishing gear settings (back and forth), the greater the potential for damage to marine waters. The catch consists of 37 species (including garbage), 2 types of main catch species (maincatch), 15 types of bycatch species and 20 species (including waste) from discard. Percentage of catch based on number (head) for main catch is 38%, bycatch 11% and bycatch 51%. Percentage of catch based on weight (kg) is for main catch 22%, bycatch 6% and waste catch 72%. The captured waste that is not valued is thrown away both alive and dead will become waste, this has triggered serious conservation problems due to the waste of valuable natural resources and causes populations of species to be endangered and even extinct. It can be said that there are no social, economic and conflict impacts that arise in the aquatic environment due to the operation of the fishing gear. Socially, the operation of the sondong fishing gear in the waters of the research location is acceptable, the decrease in fishermen's income and the (economic) catch in general is not due to the operation of the sondong fishing gear.

One of the problems faced in the management of conservation areas, including wildlife reserves, is the community activities in and around the area to meet their daily needs. They in general have traditionally carried on their traditional lives and most of them live at a very subsistence economic level. Therefore the success of the management of conservation areas including wildlife reserves is very dependent on the attitudes and support of the community both at the local and national level. Bukit Rimbang Bukit Baling Wildlife Reserve has been determined by the Government of the Republic of Indonesia through the Decree of the Minister of Forestry number SK.3977/Menhut-VII/KUH/2014 on May 23, 2014 with an area of 141,226.25 hectares (BBKSDA Riau, 2015). Tanjung Belit Village, Kampar Kiri Hulu Subdistrict, Kampar Regency is one of the villages bordering the Bukit Rimbang Hill Baling High School which has high public concern for the preservation of the forest, rivers and the surrounding environment. The people of Tanjung Belit Village have traditionally used natural resources in and around the Bukit Rimbang Bukit Baling Wildlife Reserve area to fulfill their daily needs by farming / gardening and collecting forest products and other river products. However, the availability of these forest and river resources, if taken continuously, will certainly decrease both in quality and quantity. While the necessities of life always increase along with the increasing population and the progress of the times. Therefore efforts should be made to the community and natural resources, so that the availability of natural resources and the necessities of life can be improved. This study aims to analyze the socio-economic conditions of the people of Tanjung Belit Village, identify the potential of Bukit Rimbang Bukit Baling Wildlife Reserve, formulate the Tanjung Belit Village community empowerment strategy around the Bukit Rimbang Bukit Baling Wildlife Reserve, Kampar Regency, Riau Province. The research approach used in this study is a quantitative approach to the survey method.he results showed the socio-economic conditions of the people of Tanjung Belit Village were still classified as poor and less skilled. However, local wisdom and a strong will to try to be a social capital in community empowerment. The potential of Bukit Rimbang Hill Bukit Baling has quite high potential from flora, fauna and nature tourism, but for the development of agricultural business is still limited due to the status of the wildlife reserve. The results of the study can be formulated a strategy of community empowerment in the village of Tanjung Belit around Bukit Rimbang Bukit Baling Wildlife Reserve; (a) optimize land use in agricultural business development; (b) encourage training activities to improve human resources in the context of community empowerment; (c) active community involvement in the management of the Bukit Rimbang Bukit Baling Wildlife Reserve area; (d) increasing cooperation support between the government and stakeholders in developing infrastructure supporting natural tourism around the Bukit Rimbang Bukit Baling Wildlife Reserve.

This paper discussed the productivity and economic efficiency of the fishing boat for giant threadfish (Eletheronema tetradactylum), which operated in the Malacca Straits. Eleven fishing boats with different weights (GT) were observed for their input as total cost and output as total benefit in order to calculate respective fishing boat productivity and efficiency. It was found that fishing boat activities on giant threadfish using various boat sizes were efficient with BCR>1 and profitable. However, the average economic efficiency of all boats was 1.65 with the highest efficiency of 1.74 for the 2 GT fishing boat. The average productivity of the fishing boat was Rp 4.5 million or Rp 1.5 million/GT with its capital payback period of 29 months.The highest productivity was found on the 2 GT fishing boat of Rp 5.5 million or Rp 2.8 million/GT with its capital payback period of 27 months. However, The 4 GT fishing boat was recommended to be developed for artisanal fishery of giant threadfish because its economic efficiency was relatively high of 1.71 and its produktivity was Rp 5.1 million or Rp 1.3 million/GT with capital payback period of 29 months. Keywords: economic efficiency, fishing boat, Eletheronema tetradactylum, payback period
