    The semi-wild mariculture of Caribbean King Crab (Maguimithrax spinosissimus) for coral reef restoration by Samantha Glover, Mark J. Butler, IV

    Published 2025-03-01
    “…We examined whether this bottleneck could be alleviated by the semi-wild mariculture of the Caribbean King Crab (MaguiMithrax spinosissimus)in saltwater quarries for subsequent use in coral reef restoration in the Florida Keys, Florida (USA).We surveyed the physico-chemical characteristics of 16 saltwater quarries in the Florida Keys relative to conditions in the wild and, in four quarries where crabs occurred, we examined crab population dynamics in comparison to that in the wild. Water chemistry and the availability of food (macroalgae) and crevice shelters were suitable for crab mariculture down to depths of at least 6 m. …”
