Use Of Communication Media In Wetland Fisheries Development Of Assam, Ganesh Chandra Dec 2012

Use Of Communication Media In Wetland Fisheries Development Of Assam, Ganesh Chandra

Ganesh Chandra

The study was carried out in 21 districts of Assam. Two categories of respondents, namely fishers (106 nos) of floodplain wetlands and lower level field extension functionaries (30 officials) constituted the sample for the study. The study revealed that the interpersonal communication sources like consultation with Fisheries Extention Officer Beel manager and scientists were the most important sources for obtaining information on new, improved practices. Demonstration and consultation with progressive farmers were assigned second and third rank. Field extension functionaries preferred group discussion as the main source of extension programme followed by demonstration, fisheries publication and field day/ fish farmers ...


Constraints In Adoption Of Moongbean Production Technology In Sundarban, West Bengal, Ganesh Chandra Dec 2012

Constraints In Adoption Of Moongbean Production Technology In Sundarban, West Bengal, Ganesh Chandra

Ganesh Chandra

The new agricultural technologies are considered to be the prime mover to the process of agricultural development in India. Understanding farmers’ perceptions of a given technology is crucial in the generation and diffusion of new technologies and farm household information dissemination. Pulses in India have long been considered as the poor man’s only source of protein. Moongbean (green gram) is one of the important pulse crop in India, plays a major role in augmenting the income of small and marginal farmers of Sundarban. Constraints are the circumstances or causes, which prohibit farmer to adopt improved farm technology. This constraint ...


Gentrification And Vulnerability Of Maine Fishing Communities, Cameron R. S. Thompson Dec 2012

Gentrification And Vulnerability Of Maine Fishing Communities, Cameron R. S. Thompson

Electronic Theses and Dissertations

Maine hosts numerous small fishing villages that contribute greatly to the States economy and culture. The cumulative effects of state and federal regulation, stock depletion and other socio-economic trends threaten these communities. Drawing on ethnographic research and interviews, we examine how gentrification is affecting the vulnerability and resilience of fishing communities. This study has revealed gentrification to be a complex process, which is merely the most readily recognizable symptom of forces that are reshaping the post-industrial landscape. Fishing communities can no longer be thought of as discrete entities isolated from broad social and economic changes. Technology and new markets have ...


Habitat Modeling Of Three Endemic Crayfish Species In The Black River Drainage Of Missouri And Arkansas: Factors Affecting Distribution And Abundance, Matthew Stephen Nolen Dec 2012

Habitat Modeling Of Three Endemic Crayfish Species In The Black River Drainage Of Missouri And Arkansas: Factors Affecting Distribution And Abundance, Matthew Stephen Nolen

Theses and Dissertations

The Ozark faunal region of Missouri and Arkansas harbors a high level of aquatic biological diversity, especially in regards to endemic crayfish. Orconectes eupunctus, Orconectes marchandi, and Cambarus hubbsi are three such endemics that are threatened by a limited natural distribution and the invasions of Orconectes neglectus. I sought to determine how natural and anthropogenic factors influence these three species across multiple spatial scales. Local and landscape data were used in decision tree analyses (CART) to determine their influence effect on presence/absence and density of the three species. Predictive models were validated using k-fold cross validation. O. eupunctus presence ...

Nantucket Shellfish Management Plan, Kristin Uiterwyk, Steve Bliven, Dan Leavitt, Jack Wiggin, Urban Harbors Institute, University Of Massachusetts Boston Apr 2012

Nantucket Shellfish Management Plan, Kristin Uiterwyk, Steve Bliven, Dan Leavitt, Jack Wiggin, Urban Harbors Institute, University Of Massachusetts Boston

Office of Community Partnerships Posters

Nantucket’s shellfish resources are an important part of the Island’s history, culture, and economy. Nantucket waters support one of the country’s last wild-caught bay scallop fisheries. Elsewhere along the Atlantic coast, fishing pressure, habitat loss, and disease have severely depleted bay scallop populations. Although Nantucketers continue to make a living harvesting shellfish from the Island’s waters, many do so with concern for the future of the resources and the habitats that support them. Urban Harbors Institute (UHI) provided technical assistance to the community to develop a Shellfish Management Plan (SMP) that addresses issues of water quality ...


Wetland Hydrodynamics And Long-Term Use Of Spring Migration Areas By Lesser Scaup In Eastern South Dakota, Sharon N. Kahara, Steven R. Chipps Apr 2012

Wetland Hydrodynamics And Long-Term Use Of Spring Migration Areas By Lesser Scaup In Eastern South Dakota, Sharon N. Kahara, Steven R. Chipps

Great Plains Research: A Journal of Natural and Social Sciences

Lesser scaup (Aythya affinis [Eyton]) populations remain below their long-term average despite improved habitat conditions along spring migration routes and at breeding grounds. Scaup are typically associated with large, semipermanent wetlands and exhibit regional preferences along migration routes. Identifying consistently used habitats for conservation and restoration is complicated by irregular wetland availability due to the dynamic climate. We modeled long-term wetland use by lesser scaup in eastern South Dakota based on surveys conducted during below-average (1987-1989) and above-average (1993-2002) water condition years. Wetland permanence, longitude, and physiographic region were all significant determinants of use (P < 0.01). Long-term use was best described by a quadratic equation including wetland surface area variability, an index of wetland hydrodynamics that is linked to productivity, biodiversity, and value to waterfowl. Contrary to previous findings, our study shows that over the long term, lesser scaup are more than twice as likely to use permanent wetlands as they are semipermanent wetlands. The northern region of South Dakota's Prairie Coteau, which holds the highest density of hydrologically dynamic permanent wetlands, should be considered an area of conservation concern for lesser scaup. The criteria we identified may be used to identify important lesser scaup habitats in other regions of the Prairie Pothole Region.


Using Grizzly Bears To Assess Harvest-Ecosystem Tradeoffs In Salmon Fisheries, Taal Levi, Chris T. Darimont, Misty Macduffee, Marc Mangel, Paul C. Paquet, Christopher C. Wilmers Apr 2012

Using Grizzly Bears To Assess Harvest-Ecosystem Tradeoffs In Salmon Fisheries, Taal Levi, Chris T. Darimont, Misty Macduffee, Marc Mangel, Paul C. Paquet, Christopher C. Wilmers

Aquaculture and Fisheries Collection

Implementation of ecosystem-based fisheries management (EBFM) requires a clear conceptual and quantitative framework for assessing how different harvest options can modify benefits to ecosystem and human beneficiaries. We address this social-ecological need for Pacific salmon fisheries, which are economically valuable but intercept much of the annual pulse of nutrient subsidies that salmon provide to terrestrial and aquatic food webs. We used grizzly bears, vectors of salmon nutrients and animals with densities strongly coupled to salmon abundance, as surrogates for ‘‘salmon ecosystem’’ function. Combining salmon biomass and stock-recruitment data with stable isotope analysis, we assess potential tradeoffs between fishery yields and ...

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The studies in recent years (2000-2011) have allowed to make more precise the list and ranges of Mongolian fish. This is connected with new findings as well as the continuing process of invasion of alien species. Climate change and increase of human impact transformed ranges and local distribution of fish during last 30 years. Bias on ratio of ecological guilds, number of pathological findings are increasing, and declining of local diversity, rate of growth and fecundity of many species of fish are observed. In the course of long-term observation was confirmed periodically drying of waters of the Central Asian Lake ...

Fishermen, Politics, And Participation: An Ethnographic Examination Of Commercial Fisheries Management In St. Croix, U.S. Virgin Islands, Cynthia Grace-Mccaskey

Graduate Theses and Dissertations

Currently, there is widespread debate regarding the overall status of the world's fisheries, with some researchers projecting their total collapse in only a few decades, and others concluding the situation is not quite as bleak. Additional debates include what strategies should be used to manage fisheries at various scales, and further research is needed to determine which strategies are most appropriate for use in particular situations and locales, as context is critical.

Recently, prominent common pool resources scholars have expressed the need for ethnographic approaches to studying resource management institutions in order to move beyond the current focus of ...
