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.

Seagrasses are unique marine flowering plants that play an important ecological role by yielding primary production and carbon sequestration to the marine environment. Seagrass ecosystems are rich in organic matter, supporting the growth of bio-medically important epi and endophytic microorganisms and harbor rich marine biodiversity. They are an essential food source for endangered Andaman state animal Dugongs. Seagrasses are very sensitive to water quality changes, and therefore they serve as ecological bio-indicators for environmental changes. The benthic components in and around the seagrass beds support a significant food chain for other Micro and organisms apart from fishery resources. The epiphytic bacterial communities of the leaf blades support the sustenance against the diseases. Recent reports have shown that the loss of seagrass beds in tropical and temperate regions emphasizes the depletion of these resources, and proper management of seagrass is urgent. The decline of seagrass will impact primary production, biodiversity, and adjacent ecosystems, such as reefs. Therefore, restoring the seagrass meadows could be possible with effective implementing management programs, including seagrass meadows in marine protected areas, restoration projects, seagrass transplantation, implementation of legislative rules, monitoring coastal water quality and human activities in the coastal zone. Lacunas on the seagrass ecosystem management in Andaman & Nicobar Islands are addressed.

AbstractComparing populations across temperature gradients can inform how global warming will impact the structure and function of ecosystems. Shoot density, morphometry and productivity of the seagrass Posidonia oceanica to temperature variation was quantified at eight locations in Sardinia (western Mediterranean Sea) along a natural sea surface temperature (SST) gradient. The locations are spanned for a narrow range of latitude (1.5°), allowing the minimization of the effect of eventual photoperiod variability. Mean SST predicted P. oceanica meadow structure, with increased temperature correlated with higher shoot density, but lower leaf and rhizome width, and rhizome biomass. Chlorophyll a (Chl-a) strongly impacted seagrass traits independent of SST. Disentangling the effects of SST and Chl-a on seagrass meadow shoot density revealed that they work independently, but in the same direction with potential synergism. Space-for-time substitution predicts that global warming will trigger denser seagrass meadows with slender shoots, fewer leaves, and strongly impact seagrass ecosystem. Future investigations should evaluate if global warming will erode the ecosystem services provided by seagrass meadows.

The research is aimed to reveal opportunity development of the capture fisheries in Talaud Islands Regency by using bionomy approach with Gordon-Schaefer model (Fauzy, 2005) con-cerning the dominant of illegal fishing activities around the area. The research was started by co-llected some secondary data on fish production and number of fishing units. Primary data were collected on catch composition and types of fishing gear. Gordon-Schaefer methods was applied to evaluate the tuna and skipjack resources in the area. The troll and pole and line are indicated as the dominant fishing gears used to catch the skipjack and tuna. In case of open access condition, the production will end up to 25,09 tons, while the resource rent will be end up to zero. For the development, simulations were exercised in 3 scenarios: 1) scenario of enhancing domestic fleet, 2) scenario of illegal fishing, and 3) scenario of net surplus. With those scenarios, if the illegal fishing could be eliminated, the capture fisheries in this regency could render economic value to 10 billion rupiah.

<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.
