Variação temporal da comercialização das principais espécies de peixes desembarcadas nos mercados de Belém

Abstract

This study analyzed the temporal variation in production and prices of the main fish species commercialized in the municipal markets of Belém, Pará State, from 2010 to 2024. The research was based on annual historical series of production and price data provided by the Municipal Secretariat of Economic Development (SEDCON), covering the most representative species in urban fish commercialization. Descriptive statistical analyses were applied, including measures of central tendency and dispersion, as well as the assessment of temporal variation in production and market prices. The results indicated a general downward trend in total fish production commercialized over the historical series, with an approximate reduction of 53% between 2010 and 2024, particularly concentrated in traditionally dominant species such as Dourada, Filhote, pescadas and Piramutaba. The COVID-19 pandemic period, starting in 2020, intensified this decline, causing sharp decreases in commercialized volumes, followed by only partial recovery in subsequent years. In contrast, prices showed an upward trend throughout the analyzed period, especially for species with higher market acceptance, such as Filhote, Pescada-amarela and Dourada, which presented the highest average prices and greater interannual variability. The combined analysis indicates an inverse relationship between supply and economic valuation, as well as a strong concentration of commercialization in a limited number of key species, highlighting the vulnerability of the urban supply system. The results emphasize the importance of continuous monitoring of production and prices as support for management strategies and the sustainability of fishery resources.
