The purpose of the chapter is to test the hypothesis that food safety (chemical) standards act as barriers to international seafood imports. We use zero-accounting gravity models to test the hypothesis that food safety (chemical) standards act as barriers to international seafood imports. The chemical standards on which we focus include chloramphenicol required performance limit, oxytetracycline maximum residue limit, fluoro-quinolones maximum residue limit, and dichlorodiphenyltrichloroethane (DDT) pesticide residue limit.
The role of the WorldFish Center is to research and disseminate appropriate aquaculture and fisheries technologies for sustainable agricultural intensification. To achieve these goals the WorldFish Center works in partnership with the government of Malawi. It leverages success by collaborating with both local and overseas academic research organizations, drawing funding from the global development community.
During the period of May to July 2002, An Giang University, in conjunction with the Chau Phu, Thoai Son and Chau Doc District People's Committees, and Can Tho University conducted Participatory Rural Appraisals (PRAs) in four different Provinces. The research findings from this study are presented in this report. The purpose of this exercise was to better understand the livelihoods of people living in rural areas and depending mainly on inland capture fisheries.
Slopes and intercepts of length-weight relationships obtained from 37 populations from the rivers Oti, Pru and Black Volta in Ghana were compared using a one way analysis of covariance with fixed effects. Although no significant differences were obtained from this analysis, an ANOVA comparing the magnitudes of mean condition factors (Wx100/SL3) found 9 out of 37 populations significantly different at the 0.05 level. A two-way nested ANOVA using all populations combined, however, did not yield any significant differences between the three rivers.
The programme is assessing key risk factors among highly vulnerable target groups, including female fish traders, migrant fisher folk and youth, through surveys and par ticipatory qualitative research. Based on insights from this research, programme par tners are piloting business-based interventions that will address some of these risk factors such as lack of services in remote fishing camps and transactional sex in the context of fish marketing. These pilot interventions will generate viable business models and options for wider support to the fisheries sector.
The general goals of the research of this paper are 1. To develop a broad framework for addressing approaches for reducing overcapacity in the fisheries of Southeast Asia; and 2. To examine where conflicts may arise and to provide plans to ameliorate these conflicts and its role in reducing conflicts and enhancing national and regional security. The research will attempt to meet these broad goals by pursuing the following specific objectives: 1. To describe the socio-economic conditions of fishers in selected areas around the Visayan Sea. 2.
The controlled breeding of finfish for culture is reviewed with special refer-ence to recent developments and persistent problems. Freshwater species are at present cultured on a much larger scale than brackishwater and marine species which have potential for aquaculture in arid and semi-arid lands. A reliable supply of fish seed for freshwater farming can usually be produced from captive broodstock whereas coastal aquaculture still depends largely on collection of seed from the wild.
The Southwestern coastal zone of Bangladesh is agro-based and one of the world’s most populous, poverty-stricken and food-insecure regions, with high vulnerability to climate change. Shrimp aquaculture rapidly expanded in this tidal floodplain but shrimp is highly susceptible to disease, has less contribution in local consumption, and its profitability depends on international market prices, leading the demand for improving the farming system.
Despite the success in fertilization and hatching of fish eggs with cryopreserved sperm, report on growth and survival of larvae produced from frozen-thawed sperm is inadequate. This study evaluates the applicability of cryopreserved sperm for mass seed production by comparing the growth and survival of a popular food-fish olive barb, Puntius sarana (Hamilton 1822) larvae produced from cryopreserved and fresh sperm.
This brochure is part of a series that collectively detail how a community-based assessment of climate change was used in partnership with coastal communities and provincial and national-level stakeholders in Timor-Leste and Solomon Islands. The assessment contains four distinct, but related, steps focused on supporting community-level decision-making for adaptation through a series of participatory action research activities. Each brochure in this series details a specific activity in the four-step assessment.
