Pismo clams (Tivela stultorum) supported an iconic recreational fishery in California until populations declined in the 1980s. Legal sized clams were absent from Pismo Beach, the historic epicenter of the fishery, from the early 1990s until the last few years. The clam population on Pismo Beach appears to be recovering after recruitment events in 2015 and 2021 and legal sized (114 mm) clams are becoming more abundant. As the population recovers, current estimates of key fishery metrics, such as growth rates, are essential to determining if existing fishery regulations can adequately support this recovery. The original estimates of growth rates for Pismo clams were conducted in the 1940s and found that they reached legal size in 6-7 years. A more recent aging study (2018-2019) on Pismo Beach using shell aging found that the time to legal size was 14-15 years. To understand this discrepancy in growth rates between the historic estimates and current estimate, we conducted four growth rate experiments to gain a better understanding of the current growth rates of Pismo clams on Pismo Beach. We used our long term monitoring data to conduct a cohort analysis, ran tank and caging experiments, and conducted a mark and recapture study. Comparing the estimated growth rates from these four approaches allows us to develop robust estimates of growth rate for the current population, compare this to historic estimates, and contribute to the management of this recovering recreational fishery by helping set expectations for population recovery and growth to harvestable sizes.
