High water turbulence, tidal flux, and biofouling at Alaska’s high latitude oyster farms create various challenges for growing marketable Pacific oysters (Crassostrea gigas). As oyster mariculture expands in this region, there is continued interest in developing efficient oyster grow-out methods that minimize farmer labor. Tumble culture oyster gear is configured to move with tide and wave action and be exposed during low tide, thus naturally tumbling oysters, deterring growth of fouling organisms, and reducing farm maintenance. To understand the efficiency of these tumble cages in creating marketable oysters in Alaska where this method of culture is not currently used, we stocked SEAPA cages with 500 oysters per cage, equipped the cages with HOBO temperature loggers and accelerometers, and deployed the cages in both the subtidal and intertidal at an oyster farm in Juneau, Alaska in early June 2024. After time 0 data collection in early June, subsets of 20 oysters were collected in late June, July, and September 2024, where we measured shell morphology (height, length, depth) and individual whole and wet meat weights to determine differences between the gear configurations per tidal region (intertidal cage pivot lines, subtidal cage stacks, control group of floating bags). Initial results indicate oysters from each treatment have comparable wet meat content and cup ratios (length: depth). Subtidal oysters have the highest shell growth, though growth is thin and uneven. In contrast, intertidal oysters have more rounded shell shapes which are desired for the half shell market, compared to the control oysters. Additional data on gear biofouling, water flux, temperature conditions, and labor between each tidal configuration will be quantified. Overall, these results can inform Southeast Alaska farmers about the best tumble gear configurations for sustainable, productive growth of oysters, providing opportunities for mariculture operations to expand in the region.
