Abstract
  • This study reviews patterns of consumption and expenditure of fish at home at disaggregate level and analyzes demand for nine different fish species/species group. The analysis is based on the household consumption survey in inland provinces of Thailand conducted during 1998-1999. Result shows that the annual per capita fish consumption was 29 kg. Rural –fish-producers have the highest per capita annual consumption (35 kg) followed by rural non-fish-producers (29 kg) and urban consumers (20 kg). Relatively poorer households consume lesser quantity of fish than the richer households. Moreover, consumers in different regions have different levels of consumption, preferences and levels of purchasing power. On average, fish expenditure accounted for 16 percent of the total household expenditure. A complete demand system was estimated to better understand changes in fish consumption with the changes in prices of fish and household income. The result shows that the uncompensated price, compensated price and income elasticity of demand vary across the different types of fish and across four income classes. Uncompensated own-price elasticities that capture both price effect and income effect are generally high in the high priced fish group. The variations between uncompensated and compensated own-price elasticities are marginal, suggesting that income effect from price changes is small. Income elasticities for all fish types across all income classes are inelastic. However, the low-income groups are more sensitive to income changes than the high-income groups. The study is important for policy planning on further fisheries and aquaculture development, by focusing on particular species and income groups in order to benefit the consumer and society as a whole.
