This study validated hand tong sampling as a cost-effective, quantitative alternative to "gold-standard" quadrat sampling facilitated by SCUBA diving. Side-by-side replicate sampling was conducted in six managed oyster habitat areas in Apalachicola Bay, FL, using hand tong and quadrat sampling approaches. Data were analyzed using cumulative population size distributions and conventional oyster fishery monitoring metrics. Cumulative height distributions and binned height data from all six sites demonstrated excellent agreement between quadrat and hand tong sampling approaches, with low D-statistics from Kolmogorov-Smirnov (K-S) test outputs across sampling sites, ranging from 0.06 to 0.16. Cumulative height distributions discerned from hand-tong sampling were indistinguishable from those derived from quadrat sampling at four of the six sampling sites (K-S test, P >= 0.05). Median oyster heights were statistically indistinguishable between quadrat and hand tong samples at all sites (Mann-Whitney U-test, P > 0.05). Mean oyster heights and the number of harvestable bags per acre were statistically indistinguishable between quadrat and hand tong samples at five of the six sites. Oyster counts per square meter and by size bin discerned by hand tong sampling and quadrat sampling were indistinguishable at four of the six sites. Overall, there was excellent fidelity of tong sample estimates compared with quadrat sample estimates, including detection of live oysters across size bins, when present. This study determined that standardized hand-tong sampling and quadrat sampling approaches produce functionally equivalent monitoring data. Hand tong sampling offers managers an additional tool to conduct oyster habitat assessments and monitoring under appropriate environmental conditions. Relative to quadrat sampling using SCUBA diving, hand tong sampling requires fewer trained personnel and has lower initial vessel and equipment costs, lower vessel and equipment maintenance costs, and fewer safety concerns. Together, these can facilitate the needed collection of more frequent and longer-term oyster monitoring data.

Failure of the Apalachicola Bay oyster population to recover since the 2012 fishery collapse, despite a decade of unprecedented restoration efforts and a fishery closure, indicates that the system has lost its former resilience, crossed a critical threshold between ecological steady states, and is experiencing hysteresis. This commentary contributes to the weight of evidence that reflects how accumulated system stressors led to reduced resilience and alterations in the ecological state of Apalachicola Bay. Discussion of resource exploitation, negative shell budget, salinity extremes, predator abundance, parasites, and disease underscore how these stressors accumulate over time to impact oyster populations and system resilience. Additionally, various interpretations of "resilience," "exploitation," and "restoration" have facilitated chronic resource over-exploitation and oyster habitat degradation in Apalachicola Bay. Within this context, a necessary cultural shift is described that reframes restoration and management goals to target healthy oyster habitat as the endpoint rather than using fishery metrics based on the number of harvestable oysters per acre. Failure to reframe restoration goals may be the cumulative result of resistance to accepting the presence of ecological state change, economic drivers overshadowing the weight of evidence, and outcomes not directly impacting decision makers.
