Sustainable sea urchin aquaculture

The process of obtaining sea urchin gonads, a high-demand culinary delicacy, involves the killing of the organism. Rakaj and colleagues present a sustainable no-kill sea urchin aquaculture method to produce an alternative market product of ‘caviar’ made of eggs produced by female batches.

Comment & Opinion

  • The pervasive contamination of ecosystems with active pharmaceutical ingredients poses a serious threat to biodiversity, ecosystem services and public health. Urgent action is needed to design greener drugs that maintain efficacy but also minimize environmental impact.

News & Views

  • The acute effects of climate change are already manifesting, yet coastal residents have taken little action to mitigate these effects or adapt to them. Understanding how targeted risk communications might influence their risk perceptions is critical to encouraging actions that will protect coastal properties and communities.

Research Briefings

  • We present a sea urchin aquaculture method called raking. Unlike traditional methods in which the entire gonad is the final product, thereby requiring sea urchin killing, eggs are the final product in raking. As killing of sea urchins is not necessary, several production cycles are possible with this method, enabling sustainable echinoculture.

  • The Indian government implemented the National Clean Air Programme (NCAP) in 2019 to tackle airborne particulate matter pollution. Based on monitoring data and regional model simulations, this study reveals partial achievement of NCAP targets, but highlights the critical need for additional mitigation measures to further improve air quality in India.

  • Sea urchin gonads are high-demand culinary delicacies, and depleted wild populations of these echinoderms have spurred efforts to culture them sustainably. This study presents a sea urchin aquaculture method that produces ‘caviar’ made of eggs produced by female batches, without needing to kill the sea urchins.
