Ancestral and contemporary intertidal mariculture practices support marine biodiversity in the northeast Pacific
Abstract The cultivation of seafood now outpaces extraction from wild populations. This novel state in the history of human-marine ecosystem interactions highlights the importance of identifying cultivation practices that balance production and conservation. Here, we test the hypothesis that two she...
