The Gulf of California has been widely recognized as a global marine biodiversity hotspot. For centuries, the use of aquatic resources in the region has provided food and employment to different groups of people and communities. With demand for seafood continuing to grow, domestically and globally, the pressure on these resources will increase. This raises questions about how community, government and industry can balance socioeconomic and ecological demands, including the need to meet multiple development goals, such as conservation and biodiversity targets, mitigation of greenhouse gas emissions and greater equality. This article describes the long-term impact that different human cultures have had along the coast of the Baja peninsula, with a focus on bivalve species that once created productive and critical habitats such as pearl oyster beds and reefs. Like many places worldwide these habitats are now considered to be functionally extinct and greater intervention through aquaculture and restoration is needed to enable their recovery. Using geospatial analysis that includes historical data from written and verbal sources, we developed and applied a spatial dataset and prioritization process to inform restoration and ecologically sustainable aquaculture development for bivalve species going forward.This article is part of the theme issue 'Shifting seas: understanding deep-time human impacts on marine ecosystems'.
加利福尼亚湾被广泛认为是全球海洋生物多样性热点地区。几个世纪以来，该地区水产资源的利用为不同群体的人和社区提供了食物和就业机会。随着国内外对海鲜需求的持续增长，这些资源面临的压力将会增加。这就引发了一些问题，即社区、政府和产业如何平衡社会经济和生态需求，包括实现多个发展目标的必要性，如保护和生物多样性目标、减少温室气体排放以及实现更大程度的平等。本文描述了不同人类文化在巴哈半岛沿岸产生的长期影响，重点关注双壳类物种，这些物种曾经创造了诸如珍珠贝床和珊瑚礁等高产且关键的栖息地。与世界上许多地方一样，这些栖息地现在被认为在功能上已经灭绝，需要通过水产养殖和恢复进行更大程度的干预，以使其恢复。我们利用包括书面和口头来源的历史数据在内的地理空间分析方法，开发并应用了一个空间数据集和优先排序过程，为今后双壳类物种的恢复和生态可持续的水产养殖发展提供参考。本文是主题为“变化的海洋：理解长期以来人类对海洋生态系统的影响”特刊的一部分。
