Fixed closure (FC) is a standard fisheries management tool for protecting sensitive species or species requiring conservation. However, an FC might not effectively manage migratory species because of the large uncertainties of their migration. Adaptive real-time closure (ARTC) is a tool that updates closure areas according to the latest information. This study aimed to evaluate the effectiveness of ARTC to conserve sensitive species for data-limited fisheries by a series of simulations using migration models with hotspots. In the single species simulation, the conservation ratio for the sensitive species in FC varies widely at greater migration uncertainty. In ARTC, a longer duration of a hotspot resulted in a higher conservation ratio. When the mean duration of hotspots was medium or long, the conservation ratio for the sensitive species was more than 50 % in more than 99 % of the simulation trials. In multispecies fisheries, a clear trade-off was observed between the conservation ratio of sensitive species and other species. ARTC was more effective than whole closure when the proportion of sensitive species was high or without closure when the proportion was low. Conditions in which ARTC was most appropriate were described for hotspot duration, increased numbers of individuals in a hotspot, and the relative value of conservation, representing the ratio of the value of conserving sensitive species to one of catching other species.

AbstractIn addition to their role as a fisheries management tool, discard bans can be effective in improving knowledge of total catches via the requirement to land and report all catches. This shifts the focus to understanding the scale of unreported catches in fisheries, rather than only on discards. However, the presence of a discard ban can cause problems with estimation process, as it involves the observation of illegal activities, and the complex sources of unreported catches require a different approach to estimation. The Norwegian discard ban was introduced in 1987 as part of a wider suite of regulatory measures to improve exploitation patterns in commercial fisheries, but a framework for the regular estimation of unreported catches has yet to be established and operationalised. Here, we aim to identify global best practices for estimating unreported catches under a discard ban and assess their applicability to Norwegian fisheries. We approach this in three steps: (1) defining the scope of an estimation, (2) data collection, and (3) the actual procedure for estimation. We discuss how each step can affect the quality of an estimate with regards to accuracy, precision, practical limitations and whether the estimate is fit for purpose. Finally, we provide a list of recommendations for future studies and identify key knowledge gaps and limitations regarding their application to Norwegian fisheries.

The Nassau grouper, Epinephelus striatus, was once an important commercial fish species in the Caribbean, but is now considered commercially extinct throughout its range. Protection measures have included protection of adults via seasonal closures and spawning aggregation site reserves (SASRs). Marine protected areas (MPAs) are a promising fisheries management tool being used increasingly worldwide but are not specifically directed at the conservation of Nassau grouper. This thesis uses Belize as a case study location to determine how the established MPA network may contribute towards its protection. It was found that the Belize MPA network as a system may not contribute greatly, however, on an individual basis some MPAs contribute more to protection than others. Those MPAs which have characteristics most suitable for this species are Gladden Spit and Silk Cayes, Sapodilla Cayes, Bacalar Chico, Glovers Reef, Hol Chan, and South Water Caye Marine Reserves.

Marine protected areas (MPAs) are a common fisheries management tool that relies on the assumption that species protected within a spatially-explicit area are allowed to recover and later “spill over” the boundaries of the MPA where they may be harvested. By fully protecting an MPA, species inside will grow and reproduce a steady supply of “spilled over” fish to be harvested. But how large of an area should you protect at a minimum to offer this benefit?

Pengelolaan perikanan di Indonesia saat ini belum sepenuhnya mampu mengatasi motivasi perlombaan menangkap ikan. Kondisi yang dikenal sebagai open access ini, perlu segera diatasi untuk mencegah berlanjutnya tangkap lebih. Artikel ini bertujuan untuk menjelaskan konsep Hak Pengelolaan Perikanan (HPP), yang berpotensi diterapkan sebagai alat pengelolaan perikanan termasuk yang berada dekat pantai di Indonesia untuk mengatasi masalah perikanan open access. Metoda qualitative content analysis yang ditriangulasi melalui diskusi kelompok terfokus melibatkan para ahli, pengambil keputusan dan praktisi, digunakan untuk menjelaskan konsep HPP di Indonesia. Hasilnya menunjukkan bahwa pendekatan pengelolaan HPP melegitimasi entitas pemegang HPP mengamankan kesempatannya menangkap ikan secara ekslusif dengan mencegah pihak lain mengeksploitasi sumber daya ikan secara berlebihan. Pembelajaran dari negara lain menunjukkan bahwa HPP yang diintegrasikan kedalam kerangka rencana pengelolaan perikanan, bisa mengatasi permasalahan perikanan open access, karena mampu meredam motivasi dan tindakan nelayan dalam melakukan perlombaan menangkap ikan. Penggunaan ilmu pengetahuan kontemporer dan kearifan lokal dalam menentukan batasan tangkapan lestari dibarengi dengan upaya pemantauan dan penegakan aturan menentukan keberhasilan penerapannya. Terlihat juga bahwa praktek tradisional seperti Sasi di Maluku yang dimungkinkan oleh adanya pengakuan hak ulayat ‘petuanan laut’ merupakan konsep pemanfaatan sumber daya alam secara eksklusif yang selaras dengan esensi dari HPP. Direkomendasikan agar model pengelolaan berbasis HPP ini dilegitimasi kedalam peraturan perundang-undangan, termasuk Undang-Undang Perikanan Republik Indonesia. The existing management measures of Indonesian fisheries has not yet successfully resolved the overfishing. Fishers are still motivated to race for fish resources as typically occurs in an open access fisheries. This circumstance must be addressed immediately to prevent fisheries collapse. This research aims to describe a concept of Fisheries Management Rights (FMRs) as a management tool. This concept is potentially applicable in Indonesia, especially for near-shore fisheries. A qualitative content analysis method, triangulated through focus group discussions that involved experts, decision makers and practitioners was used to describe FMRs concept. The results indicated that this approach legitimizes the entities of the right holders to secure their exploitation right and to prevent others from over exploiting their fisheries resources. Lessons learnt from other countries showed that this approach that have been  integrated within fisheries management plan, successfully addressed open access problem as it prevents fishers’ motivation to the race for fish. This approach need the contemporary and traditional sciences to inform allowable catch to ensure the success implementation. For instance, “Sasi”, traditional fishing right in Maluku  is have similar framework with the contemporary FMRs. Therefore, FMRs should be acknowledged and adopted into Indonesian’ regulations to prevent the over-exploitation
