Skipjack tuna (Katsuwonus pelamis), should be managed properly because even though it is renewable, natural resources can be depleted. One approach in managing fish resources is by modeling. The purpose of this study is to determine the maximum sustainable yield, the level of utilization and effort of skipjack tuna. Data on catches as well as catch efforts of skipjack tuna were collected from 9 fisheries year books of Luwu Kabupaten (District). The surplus production model used is the Schaefer, Fox, Walter & Hilborn model. Schaefer model obtained by MSY = 1541.08 tons and Fopt = 243 trips; Fox model obtained maximum sustainable yield value (YMSY) of 1602,244 tons, maximum sustainable fishing effort (fMSY) of 303 units and maximum sustainable CpUE value (UMSY) of 5.29 tons trip-1; the Walter & Hilborn model found potential stocks of sustainable reserves (Be) skipjack in Luwu district amounted to 935.72 tons year-1. Utilization rates of the skpjack tuina indicate the fish is still under exploitation.

<p>ABSTRACT<br />Yellowstripe scad included the one of commodity that has an important economic value in the Sunda Strait. Commonly, this species processed by Pandeglang fishermen to be the boiled fish, salted fish, grilled fish, besides it also traded in fresh or frozen fish product. The high market demand can not offset the production of this species from the nature. Therefore, it needed an information about resources of yellowstripe scad in the waters of the Sunda Strait in order to manage it well. The objective of this study was to estimate the maximum sustainable yield (MSY) and the optimum fishing effort (fopt), so that the yellowstripe scad resources in the waters of the Sunda Strait can be utilized optimally and sustainably. Based on the standardization analysis, the purse seine be made the standard fishing gear for estimating the MSY of yellowstripe scad. The yellowstripe scad growth patterns during the study is isometric. Trends of CPUE of the yellowstripe scad fisheries tends to decrease during 2003 to 2013. Then, this species was estimated its maximum sustainable yield (MSY) of 304.50 tons per year, with the optimum fishing effort of 12.478 trips per year. The decline of the catch per fishing effort can indicated that the yellowstripe scad fishing conditions in the Sunda Strait was having the overfishing phenomenon.</p><p><br />Key words: Sunda Strait, sustainable potential, yellowstripe scad</p><p>-------</p><p>ABSTRAK</p><p><br />Ikan selar kuning termasuk salah satu komoditas perikanan yang memiliki nilai ekonomis penting di perairan Selat Sunda. Jenis ikan ini, selain banyak dimanfaatkan oleh nelayan sekitar Kabupaten Pandeglang sebagai ikan pindang, ikan bakar, ikan asin, juga diperdagangkan dalam keadaan segar maupun dibekukan. Tingginya permintaan pasar tidak dapat mengimbangi produksi ikan tersebut di alam. Oleh karena itu, untuk memperoleh informasi mengenai tingkat pemanfaatan sumber daya ikan selar kuning di perairan Selat Sunda, diperlukan suatu kajian mengenai potensi lestari ikan selar kuning. Tujuan dari penelitian ini adalah untuk mengetahui hasil tangkapan maksimum lestari (maximum sustainable yield atau MSY) serta upaya penangkapan maksimum lestari (fopt) sehingga sumberdaya ikan selar kuning di Perairan Selat Sunda dapat dimanfaatkan secara optimal dan berkelanjutan. Berdasarkan hasil standardisasi, alat tangkap standart yang digunakan adalah purse seine. Pola pertumbuhan ikan selar kuning selama penelitian, yaitu isometrik. Hasil perhitungan CPUE menunjukkan adanya produksi yang cenderung menurun dengan upaya penangkapan yang meningkat dari tahun 2003 sampai 2013. Hasil perhitungan potensi hasil tangkapan maksimum lestari (MSY) diestimasi sebesar 304,50 ton per tahun, dan upaya penangkapan optimumnya adalah 12.478 trip per tahun. Penurunan hasil tangkapan per upaya penangkapan dapat dijadikan salah satu indikasi bahwa kondisi penangkapan ikan selar kuning di Perairan Selat Sunda sedang mengalami gejala lebih tangkap atau overfishing.</p><p><br />Kata kunci: Selat Sunda, potensi lestari, ikan selar kuning</p>

Pukat cincin merupakan salah satu jenis alat penangkapan ikan yang digunakan oleh nelayan di Indonesia untuk menangkap ikan pelagis termasuk tuna dan cakalang. Cakalang dan madidihang/tuna sirip kuning merupakan komoditas perikanan penting di Indonesia untuk kebutuhan pasar domistik dan ekspor. Penelitian ini bertujuan untuk mengetahui karakteristik alat tangkap pukat cincin pelagis besar terutama yang menangkap cakalang dan madidihang di perairan WPPNRI 572 dan 573 (Samudra Hindia). Pengumpulan data dilakukan selama tiga tahun dari 2016-2018 di 18 pelabuhan perikanan yang armadanya melakukan aktivitas penangkapan di perairan WPPNRI 572 dan 573. Indikasi proporsi ikan yang sudah dan belum matang gonad dihitung dengan membandingkan ukuran ikan dengan ukuran pertama kali matang gonad (Lm). Hasil penelitian menunjukkan bahwa alat tangkap pukat cincin sangat dominan dalam mengeksploitasi sumber daya cakalang dan madidihang dengan proporsi mencapai 95% di WPPNRI 572 dan 66% di WPPNRI 573. Kebanyakan ikan yang tertangkap didominasi oleh ikan yang belum matang gonad dengan proporsi sebesar 67% untuk cakalang dan 94% untuk madidihang. Hasil analisis menunjukkan bahwa pukat cincin tidak termasuk alat yang selektif untuk menangkap ikan madidihang. Selanjutnya untuk target ikan cakalang, ukuran mata jaring harus diperbesar untuk mencegah tertangkapnya ikan yang belum matang gonad.Purse seine is one of dominant fishing gear used to catch pelagic species include skipjack and yellowfin tuna, two commercial species in Indonesia’s marine waters. This research aimed to analyze characteristic of purse seine fishery focusing on skipjack and yellowfin tuna within FMA 572 and 573. All the catch-effort data was collected from 18 fishing ports during the period of 2016-2018. All the vessels (purse seiners) were known to be actively fished within FMA 572 and 573. Proportion of mature and immature fish were calculated by comparing the fish length with its length at first maturity (Lm). The results showed that purse seine was a significantly gear to catch skipjack tuna and yellowfin tuna with proportion of 95% in FMA 572, and 66% in FMA 573, respectively. Most of the catch were dominated by immature fish with proportion of 67% for skipjack tuna and 94% for yellowfin tuna. The study concluded that purse seine is not recommended to exploit yellowfin tuna. Futhermore for targeting skipjack tuna, mesh-size of the net need to be in creased, allowing immature fish to escape from the gear that maintain sustainability.

Perikanan tangkap di waduk, merupakan potensi yang dapat diandalkan bagi pemenuhan kebutuhan hidup masyarakat sekitarnya, sayangnya kegiatan ini belum banyak mendapat perhatian pengelolaan. Terbukti dari masih sangat rendahnya kontribusi sektor perikanan tangkap waduk ini pada perekonomian daerah. Untuk digunakan sebagai basis pengelolaan, penelitian ini dilakukan untuk menganalisis  pengaruh aktivitas produksi (penangkapan) terhadap kondisi sumber daya ikan seperti parameter biologi dan rente sumberdaya perikanan pada kondisi aktual, lestari, dan juga optimal, dengan menggunakan model bio-ekonomi standard logistik dan Gompertz. Skenario model yang digunakan adalah analisis bio-ekonomi model logistik Gordon Schaefer (GS) dengan estimasi parameter algoritma Fox, dan model Fox/Gompertz dengan estimasi  parameter biologi seluruhnya algoritma CYP. Analisis perikanan tangkap dilakukan dengan menggunakan skenario rezim pengelolaan open access, Maximum Sustainable Yield (MSY) dan Maximum Economic Yield (MEY). Hasil penelitian menunjukan adanya overfishing dan overcapacity pada beberapa tahun pengamatan yang ditandai dengan adanya kelebihan effort baik pada Model GS maupun Gompertz. Pengelolaan dengan menggunakan rezim MEY memberikan nilai rente yang paling maksimum, dengan biomass yang lebih konservatif, dan  effort yang lebih efisien, baik pada model GS maupun model Gompertz. Implikasi kebijakan pengelolaan waduk melalui rasionalisasi jumlah alat tangkap. Model MSY mengisyaratkan rasionalisasi alat tangkap lebih sedikit dibandingkan model MEY, sementara Model Gompertz mengisyaratkan penurunan alat tangkap lebih tinggi dibandingkan model GS. Alternatif pembatasan output atau kuota output juga dapat dilakukan dengan menggunakan nilai JTB. Title: Sustainable Fisheries Management in Cirata Dam: Bio-Economic ModellingCapture fisheries in the dam is a potential that can be relied for the surrounding community subsistence. Unfortunately this activity has not received much attention management. This was evident from the very low dam fisheries contribution, to the regional economy. For the purpose of fisheries management in the dam, this study was conducted to analyze the effect of production activities, on the condition of fish resources such as biological parameters and fishery resource rents on actual conditions, sustainable, and optimally, using bio-economic model of standard logistic and Gompertz. The scenario model used is the analysis of bio-economic model of logistics Gordon Schaefer (GS) with the parameter estimation of Fox algorithm, and  Gompertz model  with algorithm CYP  for biological parameter estimation. Analysis of fisheries carried out by using a scenario of open access management regime, Maximum Sustainable Yield (MSY) and the Maximum Economic Yield (MEY). The results showed overfishing and overcapacity in several years of observation which is characterized by an excess of effort both on the GS model and Gompertz. Management using MEY regime provides the maximum possible value of rents, with biomass more conservative and more efficient effort, both on the GS model and the model of Gompertz. Policy implications reveal from the study is dam management through the rationalization of the number of fishing gear or boats. MSY model suggests rationalization of fishing gear less than the model MEY, while the Gompertz model implies a decrease in fishing gear higher than the GS model. Alternative output restrictions or quotas outputs can also be implemented by using the value of total allowable catch.
