Marine fishery stakeholders are beginning to consider and implement adaptation strategies in the face of growing consumer demand and potential deleterious climate change impacts such as ocean warming, ocean acidification, and deoxygenation. This study investigates the potential for development of a novel climate changetolerant sea urchin fishery in southern California based on (pink sea urchin), a deep-sea species whose peak density was found to coincide with a current trap-based spot prawn fishery () in the 200-300-m depth range. Here we outline potential criteria for a climate changetolerant fishery by examining the distribution, life-history attributes, and marketable qualities of in southern California.

- - Understanding the demographic patterns of harvested species, especially in areas with significant geographical differences, is vital for sustainable management, particularly in fisheries that depend on roe, like the red sea urchin harvested in California for sushi markets.
- - The gonadosomatic index (GSI), which measures the proportion of body mass that is gonad, is a useful tool for assessing reproductive quality and can help predict the fishery's success in terms of price, quality, and yield.
- - The study revealed that fishermen adjust their harvesting based on the red sea urchin's reproductive cycle, but current management practices are not effectively tailored to these local dynamics, which could lead to inconsistencies in sustainable fishing goals.
