"Live Slow and Die Old: What Can We Learn From the Longest-Lived Bivalve on Earth?"
The ocean quahog (Arctica islandica) is one of the longest-living animals on Earth and can survive for more than 500 years in its northern range, an extraordinarily long lifespan for any animal! This clam species also represents an important fishery throughout much of its range, including the U.S. waters of the Mid-Atlantic.
But how do you manage commercial harvests for an animal that lives for centuries? Does extreme longevity lead to less frequent spawning and make this species more vulnerable to collapse? The first step to answering these questions, is to analyze the age and length distributions of the population. Age-length data can inform resource managers of the recruitment frequency, mortality rate, longevity and growth rates for a species (i.e., population dynamics). Let’s talk about what these numbers look like for ocean quahogs living on Georges Bank, USA, and what it means for the fishery and future research.
