Seafood consumption changes and COVID-19 impact index in West Nusa Tenggara, Indonesia.

Abstract

This empirical study examines seafood consumption patterns in the province of West Nusa Tenggara, Indonesia at the regency level, and analyzes changes in consumption patterns during the COVID-19 (SARS-CoV-2) virus outbreak. We used a stratified semi-random general population survey administered online through mobile devices from November 24th-December 31st 2020 for rapid assessment and dissemination, which received 1518 respondents. Our findings enabled us to generate a COVID-19 impact index at the regency level, indicating an urban-to-rural gradient in the degree of change in seafood consumption patterns, with rural areas incurring more changes. During COVID-19, 61% of respondents ate less seafood than normal, 66% stated seafood was more expensive, and 37% stated that the seafood they normally buy was not available. Respondents also bought 5% less fresh or raw seafood, and 4.3% more pre-cooked seafood products during the pandemic. Traditional markets, mobile vendors, and food stands remain the most frequent access points for seafood, although access decreased during the pandemic for all, with mini- and supermarket access slightly increasing. Raw and fresh seafood purchases from travelling merchants decreased 12.5% during the pandemic. A larger percentage of women (~10% more than men) eat fish at least once per week, and women eat a larger diversity of seafood products. However, men classified themselves on average in a higher income class than women both before and during the pandemic, and men were significantly more likely to agree that they had enough money to buy the food they wanted during the pandemic. Overall, respondents who indicated eating a higher frequency of fish per week, were significantly more likely to agree that they ate less fish during the pandemic. Respondents on Sumbawa island were significantly more likely to agree that the fisheries products were not available during the pandemic.
