ABSTRAK Waduk Sempor merupakan salah satu tipologi sumber daya perairan umum daratan yang bersifat multiguna, yang salah satu pemanfaatannya adalah untuk perikanan baik perikanan tangkap maupun budidaya. Tulisan ini bertujuan untuk merumuskan strategi yang tepat dalam pengelolaan perikanan di Waduk Sempor, Kabupaten Kebumen. Kegiatan penelitian ini dilakukan pada tahun 2016, data dikumpulkan melalui observasi yang kemudian dianalisis secara kualitatif dengan pendekatan deskriptif. Hasil penelitian menunjukkan bahwa berdasarkan pengaruh (power) dan kepentingannya (interest), maka stakeholders dalam pengelolaan perikanan di Waduk Sempor dapat dikategorikan menjadi dua yaitu key players dan crowd. Stakeholders yang termasuk dalam kategori key players adalah Dinas Kelautan dan Perikanan (DKP) Kabupaten Kebumen, Balai Besar Wilayah Sungai (BBWS) Serayu Opak, Kebumen Dinas Kebudayaan dan Pariwisata, Dinas Sumberdaya Air dan Energi Mineral (DSA) Kebumen dan masyarakat. Pemangku kepentingan yang termasuk dalam kategori kerumunan adalah DKP Prov. Jawa Tengah, Perusahaan Hutan Negara Indonesia (Perhutani) Kebumen, Perusahaan daerah Air Minum (PDAM) Kebumen, PT. Indonesia Power, lembaga penelitian dan universitas serta Lembaga Swadaya Masyarakat (LSM) lokal. Masyarakat khususnya nelayan di Waduk Sempor tergolong sebagai stakeholder primer karena berkepentingan secara langsung terhadap sumberdaya perikanan yang terdapat di Waduk Sempor, serta memiliki pengaruh dalam pengelolaan. Pengaruh (power) masyarakat dalam pengambilan keputusan dalam pengelolaan perikanan di waduk Sempor tergolong cukup. Pemanfaatan dan pengelolaan sumber daya perikanan di perairan umum waduk dapat direkomendasikan dengan cara menerapkan unsur-unsur ko-manajemen yang terpadu dengan program pengembangan perikanan tangkap berbasis budidaya (Culture Based Fishery-CBF). Title: Fisheries Management Strategies In The Sempor Reservoir Of Kebumen Regency, Central Java ProvinceABSTRACTSempor Reservoir is one of inland water typologies with multipurpose utilizations, one of which is for fisheries, both capture fisheries and aquaculture.The aimed of this paper is to formulate an appropriate strategy of fisheries management in Sempor Reservoir, Kebumen Regancy through the impelementation of Culture Based Fisheries Program (CBF). This research was conducted in 2016 and data was collected through observation and interview. Data was analyzed quatitatively with descriptive approached. The results showed that based on the influence (power) and interests (interest), then stakeholders in fisheries management in Sempor Reservoir can be categorized into two key players and Crowd. Stakeholders included in the key players category are Marine and Fisheries Agency (DKP) Kebumen Regency, River Region Agency (BBWS) Serayu Opak, Department of Culture and Tourism Kebumen, Water and Mineral Resources Agency (DSA) Kebumen and community. Stakeholders belonging to the crowd category are DKP Prov. Central Java, State Forest Company of Indonesia (Perhutani) Kebumen, Kebumen Water Company (PDAM), PT. Indonesia Power, research institutes and universities as well as local nongovernmental organizations (NGOs). The community, especially fishers in Sempor Reservoir, classified as primary stakeholders because of direct interest to fishery resources contained in the Sempor Reservoir, and has influence in the management. The influence (power) of the community in making decisions in fisheries management in Sempor Reservoir is sufficient. Utilization and management of fishery resources in the general waters of the reservoir can be recommended by applying the elements of co-management integrated with the development Culture Based Fishery program (CBF).

Fishing Fleets

With increase in numbers, size, and effectiveness, fishing fleets have depleted important stocks of fish, and strong international action by governments is imperative for the future viability of fishery resources. The author favors a system of an overall quota of fish, with individual quotas for boats and plants, and predicts that this will become "the accepted method of running fisheries" in 20 years. He discusses how best to organize such a system, with full consultation between governments and their national fishing industries as well as at the international level. For efficient handling of the complex issues involved and a full understanding of them, he suggests that governments should appoint to their fisheries ministries officers who have specialized in fisheries management and are able to analyze the situation in depth and advise the administrators on the implications of alternative management policies. The controls over fishing that he advocates are essential because "free fish means eventually no fish."

Understanding pest species composition and their geographic distribution of important spider mites is fundamental and indispensable to establish an integrated pest management program. From a long-term survey during 2008–2017 in mainland China, we found that Tetranychus truncatus was the most frequently sampled Tetranychus spider mite (48.5%), followed by T. pueraricola (21.2%), T. kanzawai (12.5%), T. urticae (red) (5.7%) and T. urticae (green) (4.5%). Among them, T. truncatus was the major mite pest in the north of China. T. kanzawai was the dominant species in the Middle and Lower Reaches of the Yangtze River Region and T. pueraricola was the most important species in the southwest region. Other common and serious pests include Amphitetranychus viennensis (6.8%) and Panonychus citri (3.8%). This pattern was largely different from that in 2002–2004, when T. urticae (green and red) was believed to be the most serious mite pest. The factors involved in the change of species composition are not clear and need more exploration. We suggested that the increasing corn planting range may be partly responsible for the conversion of dominant species from other spider mites to T. truncatus. Further research on the mechanisms underlying the change of dominant species will help develop integrated management strategies.

First Time

We used a bio-physical model to estimate for the first time the effect of larval drift on potential connectivity among American lobster (Homarus americanus) fisheries management areas over the geographic range of the species. The model predicted drift of larvae over distances of 50-805 km (mean = 129 km), which connected many management areas and caused marked spatial heterogeneity in retention and self-seeding versus export and import of larvae by different fisheries areas. Including mortality functions in the model resulted in less drift and settlement, and had complex effects on the amount, but not the incidence, of potential connectivity among fisheries. The model’s predictions received support from comparison of predicted settlement to landings six or seven years later in some (but not all) parts of the model domain. Although improvements are still needed to capture larval behaviours and spatial variability in larval release and mortality across the species’ range, this information is important to lobster fisheries management because the amount and direction of connectivity between fisheries can inform cooperative management strategies to sustain interconnected fisheries.

Abstract Marchal, P., and Vermard, Y. 2013. Evaluating deepwater fisheries management strategies using a mixed-fisheries and spatially explicit modelling framework. – ICES Journal of Marine Science, 70: 768–781. We have used in this study a spatially explicit bioeconomic modelling framework to evaluate management strategies, building in both data-rich and data-limited harvest control rules (HCRs), for a mix of deepwater fleets and species, on which information is variable. The main focus was on blue ling (Molva dypterygia). For that species, both data-rich and data-limited HCRs were tested, while catch per unit effort (CPUE) was used either to tune stock assessments, or to directly trigger management action. There were only limited differences between the performances of both HCRs when blue ling biomass was initialized at the current level, but blue ling recovered more quickly with the data-rich HCR when its initial biomass was severely depleted. Both types of HCR lead, on average, to a long-term recovery of both blue ling and saithe (Pollachius virens) stocks, and some increase in overall profit. However, that improvement is not sufficient to guarantee sustainable exploitation with a high probability. Blue ling CPUE did not always adequately reflect trends in biomass, which mainly resulted from fleet dynamics, possibly in combination with density-dependence. The stock dynamics of roundnose grenadier (Coryphaenoides rupestris), black scabbardfish (Aphanopus carbo) and deepwater sharks (Centrophorus squamosus and Centroscymnus coelolepis) were little affected by the type of HCR chosen to manage blue ling.

The sustainability of marine ecosystem has become a major concern the government; however, the implementation of sustainability-based fisheries management has not been fully carried out and well controlled. Therefore, having a concept of ecosystem-based fisheries management (EBFM) is essential in protecting it preserved. The aim of this study was to analyze the implementation of EBFM in Karimunjawa ecosystem, Central Java, Indonesia. The analysis of this study was based on the primary data collected from fishermen and stakeholders using in-depth interviews, and the secondary data gathered from stakeholders of Karimunjawa documentation. Meta-analysis with triangulation was invoked in this study. The result showed that the vulnerability of marine ecosystem, particularly fisheries’ resource in the pilot project is in progress. The conventional approach has not yet succeeded in managing fisheries’ resource in terms of sustainability attributes. Moreover, the EBFM has not yet proven to be a suitable approach for some reasons; although, this concept is very promising in encouraging a new paradigm for sustainable management in Indonesia with a protocol concept. This initial finding needs to be furthered in order to explore other aspects of development.

<em>Abstract.—</em>Urban and community fishing (UCF) projects are viewed as a way to provide easily accessible fishing opportunities to an increasingly urbanized society, thereby retaining and recruiting anglers and maintaining support for conservation of fisheries resources. Nearby, out-of-city fishery resources provide an option for development of UCF opportunities by municipalities lacking aquatic resources that can support recreational fishing. Examples of out-of-city fishing sites used as part of UCF projects in eight states are summarized. These out-of-city fishery resources not only provide relatively accessible fishing opportunities, but they also provide more diverse and often more natural fishing experiences. This diversity of fishing experiences may be useful for satisfying a broader angler constituency and aiding the transition of anglers from urban to more traditional, rural fisheries. Inclusion of out-of-city fishery resources in UCF programs can benefit from partnerships between state fisheries management agencies and municipal agencies and organizations.
