A trial on electrofishing for razor clams, launched in February 2018, is delivering promising results as it continues through January 2025.
Led by the Science, Evidence, Data and Digital portfolio of the Marine Directorate, the trial aims to gather local level data on razor clam populations, assess sustainable harvesting methods, and evaluate the impact of electrofishing on marine species.
Key spawning months identified
The trial, conducted in the Firth of Forth and Firth of Clyde, has involved collaboration between fishers, scientists, and regulatory bodies. Data collected, including the analysis of nearly 6,000 razor clams, has revealed vital information about the species’ spawning activity, with April and May identified as key spawning months. Scientists suggest halting fishing during these months to protect razor clam reproduction.
Stock assessments, based on voluntary data from fishers, indicate that razor clams have been harvested sustainably, with fishing mortality below FMSY (maximum sustainable yield). Remote Electronic Monitoring (REM) systems on vessels have helped ensure compliance with trial regulations and informed survey designs.
Cooperation is key
“This trial showcases the successful partnership between fishers and scientists in developing sustainable fishing practices,” the Marine Directorate said. “The data collected is invaluable, and continued cooperation is key to ensuring the long-term sustainability of the razor clam fishery.”
The report emphasises the need for ongoing data collection, regular stock assessments, and continued collaboration between stakeholders to support sustainable razor clam harvesting practices in the future.
