Presence Data

Hotspots are priority marine or terrestrial areas with high biodiversity where delineation is essential for conservation, but equally important is their linkage to the environmental policies of the overall region. In this study, fish diversity presences were linked to abiotic conditions and different habitat types to reveal multi-species and hotspots models predicted by ecological niche modelling methods within the Bay of La Paz, Mexico (south of Gulf of California). The abiotically suitable areas for 217 fish species were identified based on historical (1975–2020) presence data sets and a set of environmental layers related to distances from mangroves and rocky shores habitats, marine substrate, and bottom geomorphology conditions. Hotspot model distribution was delineated from a multi-species model identifying areas with ≥60 species per hectare and was compared to the marine conservation areas such Balandra Protected Natural Area (BPNA), illustrating how these models can be applied to improve the local regulatory framework. The results indicate that (1) there is a need for the BPNA to be enlarged to capture more of the delineated hotspot areas, and thus an update to the management plan will be required, (2) new conservation areas either adjacent or outside of the established BPNA should be established, or (3) Ramsar sites or other priority areas should be subject to legal recognition and a management plan decreed so that these vital habitats and fish diversity can be better protected.

Spatial Management

Marine conservation areas are an important tool for the sustainable management of multispecies, small-scale fisheries. Effective spatial management requires a proper understanding of the spatial distribution of target species and the identification of its environmental drivers. Small-scale fisheries, however, often face scarcity and low-quality of data. In these situations, approaches for the prioritization of conservation areas need to deal with scattered, biased, and short-term information and ideally should quantify data- and model-specific uncertainties for a better understanding of the risks related to management interventions. We used a Bayesian hierarchical species distribution modeling approach on annual landing data of the heavily exploited, small-scale, and data-poor fishery of Chwaka Bay (Zanzibar) in the Western Indian Ocean to understand the distribution of the key target species and identify potential areas for conservation. Few commonalities were found in the set of important habitat and environmental drivers among species, but temperature, depth, and seagrass cover affected the spatial distribution of three of the six analyzed species. A comparison of our results with information from ecological studies suggests that our approach predicts the distribution of the analyzed species reasonably well. Furthermore, the two main common areas of high relative abundance identified in our study have been previously suggested by the local fisher as important areas for spatial conservation. By using short-term, catch per unit of effort data in a Bayesian hierarchical framework, we quantify the associated uncertainties while accounting for spatial dependencies. More importantly, the use of accessible and interpretable tools, such as the here created spatial maps, can frame a better understanding of spatio-temporal management for local fishers. Our approach, thus, supports the operability of spatial management in small-scale fisheries suffering from a general lack of long-term fisheries information and fisheries independent data.

Tingginya intensitas aktivitas penangkapan ikan telah menyebabkan degradasi sumber daya ikan pada beberapa daerah penangkapan ikan. Salah satu langkah untuk menjaga keberlanjutan dan meminimalkan degradasi sumber daya ikan adalah membentuk kawasan konservasi laut daerah. Penelitian ini bertujuan untuk mengetahui pemanfaatan dan pengelolaan Kawasan Konservasi Laut Daerah (KKLD) Gili Sulat-Gili Lawang, Provinsi Nusa Tenggara Barat. Penelitian menggunakan metode valuasi ekonomi sumber daya untuk menganalisis gabungan data primer dan sekunder. Hasil penelitian menunjukkan total nilai manfaat KKLD Gili Sulat-Gili Lawang adalah Rp 8,99 milyar per tahun yang meliputi manfaat langsung dan tidak langsung. Hasil penelitian menunjukan pengelolaan terhadap KKLD ditinjau dari biaya, aktor atau pelaku dan aktivitas pengelolaan sampai saat ini belum optimal. Penelitian ini menyarankan perlunya menyusun strategi pengelolaan yang tepat untuk mengoptimalkan maksud dan tujuan dibentuknya KKLD. Tittle:  Utilization and Management of The Gili Sulat and The Gili Lawang Regional Marine Conservation Area.Highly intensive of fishing activities lead to degradation of fish resources in some fishing grounds. One effort to maintain sustainability of fish resources and minimize its degradation is to establish local marine conservation areas. This study aims to analyze utilization and management of Gili Sulat-Gili Lawang local marine conservation areas (or locally known as KKLD) in Wes Nusa Tenggara Province. This study applies economic valuation methods to analyze combination of primary and secondary data. Results of this study show that annual total benefit values of Gili Sulat-Gili Gili Lawang KKLD is IDR 8,99 billion which includes direct and indirect benefits. In terms of costs, actors and management activities, current management of KKLD is less optimal. Therefore, this study recommends to develop appropriate management strategies to optimize the purposes of KKLD establishment.
