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

Communication Sources Used By Fish Farmers And Field Extension Functionaries In Floodplain Wetland Fisheries Of Assam : A Comparative Study, Ganesh Chandra
Ganesh Chandra
A study was carried out in 106 floodplain wetlands of Assam with the objective of ascertaining the preference of communication media use by the fishers of floodplain wetlands and extent of their use by field extension functionaries. Two categories of respondents namely 106 lessee fishermen and 30 officials lower level field extension functionaries constituted the sample of the study. The findings revealed that the interpersonal communication sources like consultation with FEO/ Beel manager was the most important sources for obtaining information by fishers. Demonstration and consultation with progressive farmers were assigned second and third rank. Field extension functionaries preferred group …

Effects Of Pre-Treatments And Drying Temperatures On The Drying Rate And Qualityof African Catfish (Claris Gariepinus), Michael Ayodele Omodara, Adesoji Matthew Olaniyan
Michael Ayodele Omodara
Effects of pre-treatments and drying temperatures on the drying rate and the quality of African Catfish Clarias gariepinus was examined by drying samples of catfish under four different temperatures (40 0C, 45 0C, 50 0C and 55 0C) and four different pre-treatment methods (Salting, Sugaring, Blanching, and Control) using an experimental dryer. Drying of the fish samples for all the pre-treatments at 40 0C to 55 0C occurred in the falling rate period only showing that the predominant mechanism of mass transfer in drying process of catfish is that of internal mass transfer. The drying rate increases with increase in …

Efficacy, Effort, And Cost Comparisons Of Trapping And Acetaminophen-Baiting For Control Of Brown Treesnakes On Guam, Larry Clark, Peter J. Savarie, John A. Shivik, Stewart W. Breck, Brian S. Dorr
Efficacy, Effort, And Cost Comparisons Of Trapping And Acetaminophen-Baiting For Control Of Brown Treesnakes On Guam, Larry Clark, Peter J. Savarie, John A. Shivik, Stewart W. Breck, Brian S. Dorr
Brian S Dorr
Abstract: Brown treesnakes (Boiga irregularis) are an invasive species to the island of Guam. Because they have extirpated the native forest avifauna on Guam and are a threat to other Pacific islands, the development of efficient and cost-effective methods to control them is desired. We compared the efficacy, cost, and effort required to remove brown treesnakes on 6-ha plots in forest scrub on Guam, using 2 methods: trapping and poison baiting. Toxic baits consisted of dead neonatal mice adulterated with 80-mg acetaminophen. To assess efficacy, we used mark-recapture methods to estimate snake abundance on plots 12 days before and 12 …
The Direction Of Research And Management Of Double-Crested Cormorants Heading Into The 2000s: Symposium Overview And Future Information Needs, Brian S. Dorr, Christopher Somers
The Direction Of Research And Management Of Double-Crested Cormorants Heading Into The 2000s: Symposium Overview And Future Information Needs, Brian S. Dorr, Christopher Somers
Brian S Dorr
Abstract.—An overview is provided of a symposium on the direction of research and management of Double-crested Cormorants (Phalacrocorax auritus) heading into the 2000s. The current symposium built on previous efforts and described a number of focus areas of informational need, including cormorant impacts on natural resources, demographics of cormorants, assessment of control efforts, assessment of fish consumption and bioenergetics, and cormorant spatial ecology and influences on movements. The cormorant symposium highlighted a shift in research focus relative to earlier symposia, from evaluating potential impacts on commercial and natural resources to evaluating management actions in attaining desired goals. In addition, the …

Modification Of Net Configurations Of The Coda Netlauncher© To Enhance Bird Capture, Amanda M. Prisock, Brian S. Dorr, James C. Cumbee
Brian S Dorr
Abstract: We modified and evaluated capture nets fi red from the Coda Netlauncher® as a tool for capturing various avian species. We modified the netlauncher by using customized nets to maximize the area of the capture zone. We captured 137 birds, comprising 12 species, in 23 attempts between July 2008 and October 2009 using this method. Capture success rates varied from 25 to 69% were comparable to success rates reported for other capture methods for these species. However, individual capture success for different net configurations varied greatly from 3 to 65%. Minimal injuries and 2 bird fatalities were reported. The …

Towards Optimized Population Control Efficiency In Space And Time: A Modelling Framework Adapted To A Colonial Waterbird, Alban Guillaumet, Brian S. Dorr, Guiming Wang
Brian S Dorr
The double-crested cormorant is a native North American waterbird that recently underwent a dramatic population expansion. Population control efforts in the USA and Canada attempt to mitigate cormorant damages to natural resources and aquaculture. However, there is currently no coordination among the various stakeholders involved in management activities as well as no attempt to optimize population control efficiency. In this paper, we present for the first time a spatially explicit stage-structured metapopulation model parameterized for the cormorant. We developed simulation tools to get insights into the efficiency gain that can be expected from a better planning of management activities in …

Abstract.—A two-year satellite telemetry study was initiated in May 2000 at a Double-crested Cormorant (Phalacrocorax auritus) breeding colony on Little Galloo Island (LGI) in eastern Lake Ontario, New York, USA, which is managed by egg-oiling. The objective was to describe cormorant (N = 26/year) movements, specifically during the period of reproductive management by egg-oiling and seasonally (breeding, migration and wintering). Egg-oiling at two-week intervals resulted in a hatch success on LGI of 5.7% for 2000 and 2001, combined. The majority (97%) of core use areas of marked cormorants contained LGI throughout three egg-oiling treatments (six weeks), and 71% still contained …
