Ecosystem-Based Management and Marine Protected Areas. Ecosystem-based management (EBM) can be seen as a comprehensive strategy that includes the concern about the sustainable yield of fish alongside the ecosystem impacts of fishing and the impacts of fisheries management on human communities. While preventing overfishing goes a long way toward reaching its objective, protecting sensitive habitats from damaging fishing gear and reducing or eliminating bycatch of birds, mammals, and turtles must be given their due importance. Consideration should also be given to the trophic knock-on effects of fishing for one species that may cause other species less or more abundant. Marine protected areas are still considered the magic key to EBM, but their impact on total fish abundance has rarely been evaluated.

Etika menyangkut perilaku manusia yang dianggap baik atau buruk, pantas atau tidak pantas. Kini disadari bahwa etika tidak hanya menyangkut interaksi atau hubungan antar sesama manusia, tetapi juga sangat penting dalam pengelolaan sumberdaya alam. Tujuan tulisan ini adalah untuk menunjukkan pentingnya memperhatikan faktor etika dalam pengelolaan sumberdaya perikanan di Indonesia. Metode yang digunakan adalah studi literatur yang dikombinasikan dengan pengalaman lapang penulis. Kedua sumber ini dijadikan sebagai bahan refleksi pemikiran secara teoritis. Data tersebut digunakan untuk pengembangan ide atau pemikiran lebih lanjut pada tulisan ini. Keadilan sosial merupakan satu bentuk etika sosial yang sangat penting diperhatikan dalam pengelolaan sumberdaya perikanan, termasuk dalam penetapan zona penangkapan maupun perijinan alat tangkap. Dari segi etika lingkungan, etika lingkungan yang dominan di kalangan pengguna sumberdaya perikanan di Indonesia adalah antroposentrisme. Oleh sebab itu, pengelolaan sumberdaya perikanan seperti penetapan kawasan konservasi laut harus memperhatikan implikasi dari etika lingkungan ini. Tulisan ini mengusulkan perlunya mendekonstruksi etika antroposentrisme dan menggantikannya dengan etika ”teosentris”. Tittle: Ethical Factor in the Fisheries Management in IndonesiaEthics is about human conduct that considered as good or bad, proper or not proper. However, it has been acknowledged that ethics is not only important in the relation among people (human being), but also in relation between humans and their environment. The objective of this paper is to show the important of ethics to be taken into account in managing fishery resources in Indonesia. The method used was literature study combine with the author's field experiences. These data and as information where used to develop ideas and thoughts in this paper. It was argued that social justice is one of the social ethics that is very important to be considered, for example in establishing fishing zones as well as in permitting type of fishing gear to be used. Regarding environmental ethics, it was argued that the most common and dominant ethics among fishery resources users in Indonesia is anthropocentrism. Therefore, fishery resource management should pay serious attention to its implication in managing fishery resources, such as in the case of establishment of marine protected areas. This paper contended that it is needed to deconstruct the anthropocentrism and replace it with “theocentrism”.

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.
