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.

Long jawed mackerel resources are resources that are open access and common resources. The activity of catch mackerel in Indramayu district is increasing every year. In 2018 total fish production was 8423 tons while in 2019 there were 9047 tons. The utilization of long jawed mackerel resources must be based on economic and biological aspects as well as planning a sustainable use of long jawed mackerel. This study aims to analyze the conditions, efforts, and actual production of bloating fishing activities that are sustainable and optimal in Indramayu, as well as providing input into the direction of appropriate input and output management in bloating fishing activities in Indramayu Regency. The study was conducted in December 2019 to January 2020. The method used in this study was a survey method using quantitative descriptive analysis. Sample included 100 patients (age range 15-65 years) with respondents were owner fishermen, crew members, and/or boat captains, respondents were fishing using payang and purse seine. The data analysis method used is Gordon Schaefer's bioeconomic analysis. The results of the study found that the recommended fishing effort was in Maximum Sustainable Yield (MSY) 100.061 trip conditions and total production of 9011 tons, Maximum Economic Yield (MEY) conditions 98.756 trips and total production of 9.009 tons, and Open Access (OA) conditions in 197.513 trips and total production of 4.638 tons. The condition of long jawed mackerel in Indramayu Regency has experienced biological overfishing and economical overfishing. The policy recommendation is a limited entry of 27.242 trips (MSY) to 28.547 trips (MEY). Presentation of the reduction in the number of payang and purse seine fishing gear fleets under the conditions of MSY was 58% and 91,3% while for the MEY conditions were 59% and 91,7%.

An individual-based bio-economic model is presented and applied to the Bay of Biscay sole (Solea solea) fishery to investigate alternative quota management systems from a multicriteria perspective. For this study, the model integrates several institutional arrangements related to catch share management. The current French co-management system with nontransferability of quota is compared with an alternative individual transferable quota (ITQ) system in a context of transition to maximum sustainable yield. Trade-offs between ecological and socioeconomic impacts are highlighted and the effectiveness of governance scenarios is discussed in regard to the challenge of capacity adjustment. Results emphasize that the introduction of ITQs is expected to reduce by 40% the number of vessels in the fishery. While effectively mitigating the economic impacts of the transition phase to maximum sustainable yield, ITQs are also expected to increase substantially the fishing effort by trawlers, which may cause ecological concerns. The scenarios tested also include the simulation of a decommissioning scheme where subsequent decommissioned vessels are considerably different from the vessels that would lease out their quotas in an ITQ system, resulting in differentiated ecological and socioeconomic impacts between scenarios.

A brief review of the concept of Maximum Sustainable Yield (MSY) used in fisheries management is discussed. The convenience of assessing the exploited stocks with the aid of simulation is advised, because implies the possibility to analyze the age structure of the fishery in more detail, as compared to the traditional methods of fish stock assessment. Emphasis is given to the use of the MSY as limit reference point because as long as the Fishing Mortality or fishing effort required for that point is kept at lower values, the fishery will have a good chance to be sustainable. A mention of the Maximum Economic Yield is made, proposing its use a target for the management, because it is reached in general with lower F values then that for the MSY, and this way keeping the fishery in a healthy condition.

The current study was heading for determining the impact of Pakistani university students’ socioeconomic classes on their personality traits. Demographic and personality questionnaires were filled by available university students online. The stepwise regression technique facilitated to generate regression models to define impacts of different socioeconomic classes on students’ different personality traits. Different regression models highlighted the significant negative impacts of the middle upper socioeconomic class on Agreeableness, Extraversion and Neuroticism personality traits. The lower socioeconomic class was found to have positive impact on only one personality sub-trait self-discipline. Whereas, the upper lower socioeconomic class caused positive impacts on students’ trust sub-trait, Conscientiousness trait and negative impact on excitement seeking sub-trait of personality. The importance of these impacts of socioeconomic classes on different personality traits and the possible implications are discussed with respect to university students’ academic performance and academic behaviour.
