The Mekong River Basin, site of the biggest inland fishery in the world, is undergoing massive hydropower development. Planned dams will block critical fish migration routes between the river's downstream floodplains and upstream tributaries. Here we estimate fish biomass and biodiversity losses in numerous damming scenarios using a simple ecological model of fish migration. Our framework allows detailing trade-offs between dam locations, power production, and impacts on fish resources.
The fisheries sector of Vietnam plays an important role in the social and economic development of the country. The sector contributes about 3% of the GDP and fish contributes about 40% of animal protein consumption in the country. In 1999, total fisheries production amounted to 1.8 million t. Of this, 1.2 million t was derived from marine capture fisheries and 0.6 million t from aquaculture. Fish exports were valued at US$971.12 million in the same year. Vietnam’s marine fisheries and coastal aquaculture have further potential for development.
Over the past 5 years, fish processors and traders, along with government leaders, have begun to demand a change in the way Africa trades its fish. In May 2014, the second Conference of African Ministers of Fisheries and Aquaculture (CAMFA) endorsed the African Union Policy Framework and Reform Strategy for Fisheries and Aquaculture in Africa, which prioritizes fish trade and aims to promote responsible and equitable fish trade and marketing by significantly harnessing the benefits of Africa’s fisheries and aquaculture.
Chloramphenicol is a broad-spectrum antibiotic that was historically used as a veterinary drug for farm animal disease treatment purposes and it is currently used in human treatment; however, this is a banned substance. This paper investigates the impact of advancing chloramphenicol analytical standards on crustacean imports in the EU15, Japan, and North America. The paper extends the work of Disdier and Marette (2010) by exploring the differential effect of standards on products. We use a Heckman sample selection specification to address zero trade at the product level.
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.
Two opposing views exist in the literature on the potential role that international fish trade plays in economic development. While some claim that fish trade has a pro-poor effect, others denounce the negative effect of fish export on local populations’ food security and doubt its contributions to the macro-economy. In this paper, we explore this debate in sub-Saharan Africa. Our analysis did not find any evidence of direct negative impact of fish trade on food security; neither did it find evidence that international fish trade generates positive, pro-poor outcomes.
This paper provides an overview of the live reef fish market in Hong Kong, which accounted for about 15,000 t/yr (US$345 million) of live fish imports in the mid-1990s. The live fish trade has spawned a number of management concerns, including overfishing of highly-valued species, use of destructive fishing techniques and human health risks. Recent actions by the Hong Kong government in response to these concerns are reported and possible region-wide initiatives are briefly discussed in this paper.
A conceptual framework, drawn from an approach to poverty reduction known as the Sustainable Livelihoods Approach (SLA), is applied to understanding the role of freshwater prawn (Macrobrachium rosenbergii) marketing systems in southwest Bangladesh. Freshwater prawn marketing potentially provides economic returns and social benefits to the rural poor. Although the potential benefits are great, a number of constraints were identified for the longterm sustainability of prawn marketing systems.
There is an increasing ‘fish gap’ in sub-Saharan Africa (SSA), where fish supplies have failed to keep pace with the region’s growing demand. Despite the high dependence on fish for nutrition in much of the region, consumption is currently half the global average and declining. In SSA, as in many other regions globally, marine and inland capture fisheries resources are stagnating or decreasing, largely due to environmental or ecosystem changes and over-exploitation. Climate change is already altering the distribution of fish stocks and rainfall patterns upon which these fisheries depend.
Commercial trade is a major driver of over-exploitation of wild species, but the pattern of demand and how it responds to changes in supply is poorly understood. Here we explore the markets for snakes from Tonle Sap Lake in Cambodia to evaluate future exploitation scenarios, identify entry points for conservation and, more generally, to illustrate the value of multi-scale analysis of markets to traded wildlife conservation. In Cambodia, the largest driver of snake exploitation is the domestic trade in snakes as crocodile food.
