The objective of this study is to investigate the sustainability properties of the stock of the shrimp trawl
fishery in the Tonkin Gulf, Vietnam. Surplus production models of Verhulst-Schaefer and Gompertz-Fox
are applied to the shrimp trawl fishery, which is a typical tropical fishery with the characteristic properties
of small...
Program description: Do users want simpler access to "best sources" for subject research? Should libraries filter information by discipline, subject area or course? Should information be tailored to undergraduate level? This presentation will present findings from research on these and other questions.
The aim of this paper was to compare the nutritional value of some low price fish (Sardina pilchardus, Engraulis encrasicholus, Anguilla anguilla, Salmo trutta, Mugil chepalus) to high price fish with high consumption rate (Sparus aurata, Merluccius merluccius, Dicentrarchus labrax).In general, the commercial values of several fish species in Greece...
Basic research on semantic interoperability is just beginning to address support for spatial data and information. This is clearly important for data portals containing geographic information system (GIS) layers, as well as supplemental information, often with cartographic and decision support tools. Agreements on content/semantic interoperability of these resources can help...
The World Summit on Sustainable Development (Johannesburg, 2002)
encouraged the application of the ecosystem approach by 2010.
We propose a framework that deals jointly with i) ecosystem dynamics,
ii) conflicting issues of production and preservation and
iii) robustness with respect to dynamics uncertainties.
More specifically, we define robust viability kernels...
Catfish farming has increased over the past decade in Uganda. In order for this emerging industry to be sustainable, systematic production and marketing are essential. This paper discusses the existing catfish farming industry in Uganda and its value chains. Analysis is done to answer questions on the industry structure, value...
The Lake Victoria dagaa constitutes over 38% of the total fish landings from Lake Victoria in Tanzania. The fishery supports a major artisanal fishery in the country, ranking second to the Nile perch in Tanzania. However, the dagaa fishery is associated with high level of post-harvest loss (physical and quality...
The paper discusses contribution of dagaa Rastreneobola argentae fishery to Tanzanian economy. It uses data from two studies conducted in Lake Victoria as well as literature retrieved from Fisheries Division and other institutions. Results indicate that dagaa fishery generates an average monthly income over $150 to individual fisher/trader, provided employment...
This study carried out an appraisal of fresh fish marketing in Ondo-State, Nigeria. It
specifically examined the socio-economic characteristics of fresh fish marketers in the study
area, determined profitability and examined market structure for fresh fish in the study area .A
multi-stage sampling technique was used to select 45 fresh...
Fish is an important source of protein which is highly needed for human beings to experience
necessary growth and development. This is the reason for the phenomenal rise in the
consumption of fish in order to meet up with the body nutritional requirements. Therefore,
marketing of this source of protein...
Women are recognized as agents of changes and development .Their involvement in aquaculture is one issue that needs to be addressed when dealing with rural communities and poverty alleviation among the rural women .The major way to ensure that women utilize their full potentials in profitable aquaculture is to provide...
In the past, fisheries and aquaculture researchers in Africa have been handicapped by poor access to current scientific literature and difficulties in getting published in visible outlets. Efforts in the past decade to improve access, awareness and use of information have flourished. We examine whether these efforts are reflected in...
This project examines the rulers of late medieval Castile, Enrique IV and Isabel I, and the controversies surrounding their reigns.
The paper begins with an examination of Isabel’s youth and education prior to her life at Enrique’s court. From there the troubles in Enrique’s reign are detailed beginning with discontented...
The linefish sector is one of the 10 commercial fisheries in Namibia. This sector is made up of two subsectors: commercial right holders and angling. The angling subsector is further divided into two types of fishing activities; subsistence angling which serve as a source of food supply and recreational angling...
In this study, the gene expression levels between 6 month old mice and 26 month
old mice were compared. The purpose of this research was to identify genes that are
differentially regulated due to aging. The results showed 148 significantly differentiated
genes in the analysis of a total of 44,170...
Saccharina sessilis, lettuce kelp, is a macroalgae that contributes to the primary production in the intertidal zone off of the Oregon Coast. Macroalgae can serve as a bioindicator of increased nutrient input, water quality, and shifts in the intertidal environment. Competition for light exists between macroalgae species and with other...
The release of transgenes into the environment by transgenic plant species is a significant ecological concern, and consequently a containment method for these genetically modified organisms is highly sought after. For poplar trees, an option for containment is to produce trees that do not flower and therefore cannot spread genetic...
Fusarium solani is a chronic disease that causes root rot which affects bean production worldwide. Recently, a QTL map was generated which identified several SNPs which were found to be associated with resistance to the pathogen. To be useful in a breeding program, INDELs must be identified which co-seggregate with...
