UBC Study Finds Aquaculture Shift Toward Farming Carnivorous Species Over Past 70 Years

A recent study conducted by researchers at the University of British Columbia (UBC) has identified a significant shift in global aquaculture practices over the past 70 years. The findings reveal that the industry is increasingly focusing on farming species with lower sustainability potential, raising concerns about its alignment with global environmental and food security goals.

The research highlights that while aquaculture has experienced rapid growth as a key source of food production, this expansion has come at an environmental cost. The study points to a trend toward cultivating species that require higher levels of feed and resources, such as carnivorous fish, rather than more sustainable options like herbivorous or filter-feeding species. This shift could undermine efforts to reduce the environmental footprint of food systems and meet international sustainability targets. Researchers emphasize that understanding these trends is critical for guiding future policies and practices in the aquaculture sector.
