Aquaculture or fish farming has become an essential solution for providing sustainable food sources as the global population grows. While traditional aquaculture feed sources involve fishmeal and oil obtained from wild fish stocks, the industry has shifted towards using crop-based feeds such as soybeans and corn. However, this alternative can have significant adverse environmental and health impacts because of the industrial and agricultural methods used to produce these crops. The aquaculture industry must prioritize sustainable practices and choose crops with a lower environmental footprint or support alternative crop production practices. Additionally, there is a need to balance food production with biodiversity conservation using strategies such as the sharing/sparing framework, which separates areas for human use from areas for conservation. The article also highlights the effectiveness of land-sparing as a conservation strategy, which separates areas for human use, such as agriculture and urban development, from areas for nature conservation.
