Import demand functions for live reef food fish are estimated for Hong Kong, in aggregate and for individual fish species. Cross-price, income and population elasticities, and the impact of SARS and Chinese New Year on demand, are estimated. Results show that price has a smaller influence on import demand than expected. The most influential factor is Chinese New Year. The price of low and medium-value species exhibited a negative impact, whereas the price of very high-value species exhibited a positive impact, on demand. This suggests that high-value live reef species may be Veblen goods, where consumption increases as a direct function of its price, in this case due to associated prestige and status.

Cointegration analysis is used to test for relationships between wholesale and retail prices in demand countries for live reef fish species in aggregate and then by species. Results indicate that wholesale and retail prices of live reef fish species are cointegrated and form part of the same market. An analysis of price integration between wholesale supply and wholesale demand prices is undertaken using a high value reef fish exported to Hong Kong from Australia.

This paper explores market chain issues for the live reef food fish trade, a highvalue export fishery involving nearly 20 countries in the Asia-Pacific region, with demand centred in Hong Kong. The characteristics of the trade mean the market chain is more extended than most seafood chains. With supply dominated by artisanal fishers in developing countries, there are concerns that gains are being unevenly distributed along the chain. This paper describes the market chain for live reef fish and identifies key cost, revenue and risk components that may affect the distribution of value along the chain.

There is a paucity of research and limited empirical data on market chains in developing country fisheries, especially small-scale fisheries. With these fisheries dominated by artisanal and subsistence fishers, concerns that gains will be unevenly distributed along the chain are more acute. Differences in gains extracted along the market chain are usually attributed to marketing costs incurred by upstream agents. The magnitude of these costs will vary with market chain complexity, distances to market and processing, storage and transportation requirements. Another factor often identified as affecting the distribution of value along the chain is risk; however risk is rarely explicitly incorporated into market chain analysis to explain divergences in value gains extracted. All these factors are exacerbated in low technology small-scale fisheries.

The total regional trade in LRFF is considered to be around 30,000 tonnes per year with an estimated 15–20,000 tonnes of this going into Hong Kong (Sadovy et al., 2004). More than 20 countries in Southeast Asia and the Pacifi c supply fi sh to this market using a variety of capture techniques and transport technologies.

They are highly-prized food fishes that are targeted by subsistence, artisanal, commercial and recreational fisheries throughout their geographic range. Plectropomus have broadly similar diets and habitat requirements to other tropical groupers, but typically have faster growth and higher natural mortality rates. Although these characteristics are expected to increase population turnover and reduce innate vulnerability to environmental and anthropogenic impacts relative to other groupers, many Plectropomus populations are in decline due to the combined effects of overfishing and habitat degradation. In many locations, stock depletion from uncontrolled fishing, particularly at spawning aggregation sites, has resulted in local fishery collapse. Therefore, improved management of wild populations is urgently required to ensure conservation and sustainable fisheries of Plectropomus. Where possible, a combination of no-take marine reserves, market-based

Approximately twenty countries in the Asia-Pacific region supply these markets. A number of economic, environmental and social issues have arisen from the trade; including the sustainability of wild stocks (it is likely that future demand will need to be met from mariculture), the use of destructive fishing practices in some countries, and the market effects of economic shocks (such as the Asian economic crisis). This paper presents a theoretical framework and preliminary analysis of the trade. Key data challenges and linkages to other fishery models are also outlined.
