This plant relies partially on unsustainable species. In 2024, a certificate issued by the MarinTrust Improver Programme documented that chub mackerel and frigate tuna were among the fish species processed by the plant.¹ That same year, chub mackerel was classified as “overexploited” and frigate tuna was listed as being at risk of “overfishing” and “overexploitation” in Ecuadorian waters, according to the Public Aquaculture and Fisheries Research Institute.² This means that fish were caught faster than they could reproduce, shrinking the population and reducing their capacity to recover to healthy levels.

In 2018, Productos Pesqueros joined the Ecuador small pelagics Fishery Improvement Project (FIP), a program that claims to help make participating fisheries more sustainable.³ Plants and their parent companies routinely use involvement in FIPs and other such programs to evidence their environmental stewardship, even when participation in them does not result in actual improvement in the health of the relevant fishery. As of 2024, Productos Pesqueros remained as part of the Fishery Improvement Project and the MarinTrust Improver Programme, despite the decline of these species in the region.⁴ Subsequently, critics have questioned whether the FIP makes genuine progress toward better fishery management or if it is merely a form of greenwashing.
