Whitefish wars: Pangasius, politics and consumer confusion in Europe

Rapid growth in production of the farmed Vietnamese whitefish pangasius and its trade with the European Union has provoked criticism of the fish's environmental, social and safety credentials by actors including WWF and Members of the European Parliament and associated negative media coverage. This paper reviews the range of claims communicated about pangasius (identified as a form of mass mediated risk governance), in light of scientific evidence and analysis of data from the EU's Rapid Alert System for Food and Feeds food safety notification system for imported seafood.

Wetlands of the Yellow River Delta: a heritage to conserve and treasure

The wetlands of the Yellow River delta face a situation common in many developing countries where the quest for rapid economic growth brings development to the doorstep of natural ecosystems and threatens their health and survival. This brief examines the several issues relating to wetlands in the Dongying municipality. Can the wetlands in Dongying coexist with the modern development that is creeping towards them? Is there sufficient appreciation that these wetlands are worth caring for?

Watershed governance: livelihoods and resource competition in the mountains of mainland Southeast Asia

This paper examines the challenges of managing the upper watersheds of mainland Southeast Asia, taking local livelihoods and resource competition as its point of departure. The analysis presents the factors of change that drive economic, environmental, and social transfromations of the area. These dynamics highlight the need for greater attention to the governance and challenges of the uplands- how are decisions over resource use made, who makes them, and to whose benefit?

Water quality, fish production and economics of Nile Tilapia, Oreochromis niloticus, and African catfish, Clarias gariepinus, monoculture and polyculture

Tilapia is the main cultured fish species in Egypt, contributing 43.5% of farmed fish production and 24% of total fisheries production. The main problem facing tilapia producers is early reproduction before fish reach marketable size, leading to overpopulation and smaller fish at harvest. Approaches to this problem include the use of all-male hybrids and hand-sexing to remove females.

Water and fisheries

This paper highlights the importance of fisheries and aquaculture in management of the world’s water resources. It underlines the value of these resources and the critical importance of managing water quantity and quality for fisheries and aquaculture as well as for other human uses. This will require more holistic approaches to water management and the effective governance systems these require.

Warning signs unheeded in South Pacific invertebrate trade

Nearshore marine resources play a significant role in the lives of South Pacific islanders and can be critical to the economies of nations in the region. However, few countries have adequate management controls in place to ensure harvests remain at sustainable levels, and so determining current levels of utilization is far from easy. A lack of information about the volume of both domestic and international trade in marine invertebrates in high demand is a growing concern.
