Marine protected areas (MPAs) are an area-based conservation strategy commonly used to safeguard marine biodiversity and ecosystem services. Population connectivity governs the exchange of individuals among spatially fragmented habitats and is an essential criterion in the design of MPAs. However, detailed computational methods for connectivity are inconsistently applied in management decisions. We reviewed the scientific and management literature to explore the use of connectivity in MPAs located in countries with advanced marine spatial planning. Only 7.8% of 739 MPAs considered connectivity as an ecological criterion, although it has been increasingly used since 2007, suggesting progress in spatial conservation planning towards the use of ecological conservation objectives. In most cases, connectivity was measured implicitly using either rules of thumb or size and spacing guidelines. Of the MPAs that considered connectivity, 67% were for state marine conservation areas or reserves in California and commonwealth marine reserves in Australia. This pattern indicates substantial geographic biases and significant differences in conservation planning and prioritization among countries. We suggest that the incorporation of connectivity in conservation planning needs to become more accessible to practitioners. Prioritizing connectivity as an ecologically important criterion in MPA design will more adequately address metapopulation persistence and recovery.

Different Levels

In the last decades, several targets for marine conservation were set to counter the effects of increasing fishing pressure, e.g., protecting 10% of the sea by 2020, and establishing large-scale marine protected areas (LSMPAs). Using the ‘reconstructed’ catch data for 1950 to 2018 made available by the Sea Around Us initiative, we show that the declaration of an exclusive economic zone (EEZ) in 1983 by the U.S.A. and its protection by the U.S. Coast Guard had a much bigger impact on catches around the Northwestern Hawaiian Islands than the subsequent creation of a LSMPA. This is similar to Pitcairn Islands, a UK territory. Trends differed sharply in the Galapagos and New Caledonia, where neither their EEZ declaration nor the LSMPA (by Ecuador in 1988 and by France in 2014) stopped local fisheries from continuous expansion. Our results also demonstrate that in the studied multizone LSMPAs continued local fishing induces a ‘fishing down’ effect wherein the mean trophic level (TL) declined, especially in the Galapagos, by 0.1 TL per decade. Stakeholders’ responses to a short questionnaire and satellite imagery lent support to these results in that they documented substantial fishing operations and ‘fishing the line’ within and around multizone LSMPAs. In the case of EEZs around less populated or unpopulated islands, banning foreign fishing may reduce catch much more than a subsequent LSMPA declaration. This confirms that EEZs are a tool for coastal countries to protect their marine biodiversity and that allowing fishing in an MPA, while politically convenient, may result in ‘paper parks’ within which fishing can cause the same deleterious effects as in wholly unprotected areas.

Kawasan Konservasi Perairan Daerah (KKPD) ditetapkan untuk berbagai tujuan, termasuk melindungi spesies dan habitat laut, melestarikan keanekaragaman hayati laut, memulihkan stok perikanan, mengelola kegiatan pariwisata, dan meminimalkan konflik di antara beragam pengguna sumber daya. Oleh karena itu, timbul pertanyaan apakah pengelolaan Kawasan Konservasi Perairan Daerah (KKPD) di Selat Dampier Raja Ampat telah dilakukan secara efektif untuk memperoleh hasil yang berkelanjutan serta meningkatkan status sosial ekonomi masyarakat yang ada di kawasan tersebut.Analisis penerapan zonasi dalam pengelolaan kawasan konservasi laut Selat Dampier diukur dengan memetakan kelimpahan dan biomasa ikan karang, memotret persepsi nelayan tentang zonasi serta menilai tingkat kepatuhan nelayan pada batas-batas zonasi. Penelitian ini dilakukan di kawasan konservasi Selat Dampir, Kabupaten Raja Ampat, Provinsi Papua Barat, antara November 2016 dan Oktober 2017. Data dikumpulkan dengan menggunakan metode survei, termasuk data primer dan sekunder. Metode transek sabuk, dilakukan pada kedalaman 3 m, digunakan untuk mengukur kelimpahan dan biomasa ikan. Responden adalah nelayan terumbu karang yang tinggal di Desa Saonek, Desa Yenbuba, Desa Friwen dan Desa Arborek. Data sekunder diperoleh dari beberapa sumber (Dinas Perikanan Kabupaten, BPS, jurnal ilmiah, dan laporan penelitian). Data dianalisis secara deskriptif dan metode tabulasi silang. Hasil penelitian menunjukkan bahwa sistem zonasi pada pengelolaan kawasan konservasi di perairan Selat Dampier, Raja Ampat dapat dikatakan cukup efektif terlihat dari kelimpahan ikan dan biomasa yang cukup tinggi pada zona inti dan zona wisata (sebagai Daerah Perlindungan Laut/DPL) dimana pada kedua zona tersebut nilainya 1.5 sampai 2 kali dibandingkan dengan zona perikanan (Non DPL). Rata-rata tingkat kesadaran dan kepatuhan nelayan untuk tidak melakukan penangkapan ikan di daerah zona inti dan zona wisata cukup tinggi yakni 95%, Persepsi sebagian besar nelayan mengekspresikan kesadaran lingkungan dan pengetahuan yang baik tentang kawasan konservasi.Title: EFEKTIVITAS ZONASI DALAM PENGELOLAAN  PERIKANAN KARANG DI KAWASAN KONSERVASI PERAIRAN  SELAT DAMPIER, RAJA AMPAT Marine Protected Areas (MPAs) are defined for various purposes, including to protect marine species and habitats, to conserve marine biodiversity, to restore fishery stocks, to manage tourism activities, and to minimize conflicts among diverse resource users. Therefore, question arises whether there has been effective management of the Marine protected Area in the Raja Ampat Dampier Strait in order to achieve sustainable results and improve the socio-economic status of its society. Analysis of the zoning system in the management of the Dampier Strait was measured by mapping the abundance and biomass of reef fish, capturing fishers’ perception towards zoning and assessing the level of fishers’ compliance at zoning boundaries. This research was conducted in the Dampir Strait conservation area, Raja Ampat District, West Papua Province, from November 2016 to October 2017. Primary and secondary data were collected through surveys. The belt transect method was carried out to a depth of 3 m to measure the abundance and biomass of fish. Primary data were collected from coral reef fishers living in Saonek Village, Yenbuba Village, Friwen Village and Arborek Village. Secondary data were taken from several sources (District Fisheries Service, BPS, scientific journals, and research reports). Data were analyzed descriptively and cross tabulated method. The results showed that the zoning system was effective to manage the conservation areas in the Dampier Strait waters, Raja Ampat since there are abundance of fish and high biomass in the core zone and tourist zo9ne (as Marine Protected Areas) with 1.5 to 2 times amount compared with the fisheries zone (Non DPL). The average level of awareness and average compliance of fishers to prevent themselves from fishing activities in the core zone and tourism zone is 95 %. Most fishers express high environmental awareness and good knowledge toward conservation areas.

Nursery Habitats

Marine Protected Areas (MPAs) must function as networks with sufficient stepping-stone continuity between suitable habitats to ensure the conservation of naturally connected regional pools of biodiversity in the long-term. For most marine biodiversity, population connectivity is mediated by passively dispersed planktonic stages with contrasting dispersal periods, ranging from a few hours to hundreds of days. These processes exert a major influence on whether threatened populations should be conserved as either isolated units or linked metapopulations. However, the distance scales at which individual MPAs are connected are insufficiently understood. Here, we use a biophysical model integrating high-resolution ocean currents and contrasting dispersal periods to predict connectivity across the Network of MPAs in Western Africa. Our results revealed that connectivity differs sharply among distinct ecological groups, from highly connected (e.g., fish and crustacea) to predominantly isolated ecosystem structuring species (e.g., corals, macroalgae and seagrass) that might potentially undermine conservation efforts because they are the feeding or nursery habitats required by many other species. Regardless of their dispersal duration, all ecological groups showed a common connectivity gap in the Bijagós region of Guinea-Bissau, highlighting the important role of MPAs there and the need to further support and increase MPA coverage to ensure connectivity along the whole network. Our findings provide key insights for the future management of the Network of MPAs in Western Africa, highlighting the need to protect and ensure continuity of isolated ecosystem structuring species and identifying key regions that function as stepping-stone connectivity corridors.

AbstractConservation of the high seas marine environment poses a significant challenge to policy-makers and managers. Marine conservation efforts are often hindered by the lack of data and the difficulties in addressing multiple, and typically conflicting uses. The majority of extant Marine Protected Areas (MPAs) are in coastal or tropical regions within national jurisdiction. Conservation of high seas MPAs has emerged on the international agenda as a critical issue requiring the application of novel approaches, international cooperation and political will. Knowledge and understanding of the marine environment and data on marine biodiversity are all typically limited for the high seas, and the use of surrogates to assist in the identification of areas of high conservation value is one possible mechanism to address and potentially overcome these limitations. Drawing upon a database spanning more than 20 years and containing approximately 140 000 records of seabird sightings at sea, this study assesses the potential use of seabirds as surrogates for marine biodiversity in the Indian sector of the Southern Ocean. At-sea ranges, species diversity and the distributions of endangered species may be appropriate selectors or filters to identify areas with high conservation values. Integrating policy with science provides an appropriate mechanism to identify and prioritise MPAs in the Southern Ocean.

Abstract Despite strong legal duties and political commitments for marine conservation and ecosystem-based management, biodiversity in the high seas and the Area (jointly referred to as areas beyond national jurisdiction (ABNJ)) is under increasing threat. One important tool for enhancing conservation and multi-sectoral cooperation is the establishment and maintenance of representative networks of marine protected areas (MPAs). This commentary reviews potential avenues for accelerating progress towards representative MPA networks as part of a larger-scale effort towards improving the conservation and sustainable use of marine biodiversity beyond national jurisdiction. It builds on the report by Petra Drankier, Marine Protected Areas in Areas beyond National Jurisdiction, Report on Research Question 2 of the Study on ‘Biological Diversity and Governance of the High Seas’ (2011), which describes the applicable global and regional conventions by discussing the strengths and weaknesses of proposed avenues for progress, including a possible multilateral agreement under the UN Convention on the Law of the Sea (LOSC). The commentary concludes with some observations for a pragmatic path ahead.

Recovery Education

Compliance with spatial fishing regulations (e.g., marine protected areas, fishing closures) is one of the most important, yet rarely measured, determinants of ecological recovery. We used aerial observations of recreational fishing events from creel surveys before, during, and after 77 Rockfish Conservation Areas (RCAs) were established in British Columbia, Canada. There was no evidence of a change in fishing effort in 83% of the RCAs, and effort in five RCAs increased after establishment. Fishing effort in open areas adjacent to the RCAs declined with time and was higher than effort in the RCAs in all 3 years. Next, we used compliance data for 105 RCAs around Vancouver Island to model the drivers of compliance. Compliance was related to the level of fishing effort around the RCA, the size and perimeter-to-area ratio of RCAs, proximity to fishing lodges, and the level of enforcement. Noncompliance in RCAs may be hampering their effectiveness and impeding rockfish recovery. Education and enforcement efforts to reduce fishing effort inside protected areas are critical to the recovery of depleted fish stocks.

Mexican Caribbean

In the Mexican Caribbean, 15 marine protected areas (MPAs) have been established for managing and protecting marine ecosystems. These MPAs receive high anthropogenic pressure from coastal development, tourism, and fishing, all in synergy with climate change. To contribute to the MPAs’ effectiveness, it is necessary to provide a long-term observation system of the condition of marine ecosystems and species. Our study proposes the establishment of a new marine biodiversity monitoring program (MBMP) focusing on three MPAs of the Mexican Caribbean. Five conservation objects (COs) were defined (coral reefs, seagrass beds, mangroves, marine turtles, and sharks-rays) for their ecological relevance and the pressures they are facing. Coral reef, seagrass and mangroves have multiple biological, biogeochemical and physical interactions. Marine turtles are listed as endangered species, and the status of their populations is unknown in the marine area of the MPAs. Elasmobranchs play a key role as top and medium predators, and their populations have been poorly studied. Indicators were proposed for monitoring each CO. As a technological innovation, all information obtained from the MBMP will be uploaded to the Coastal Marine Information and Analysis System (SIMAR), a public, user-friendly and interactive web platform that allows for automatic data management and processing.
