The Continuous Underway Fish Egg Sampler (CUFES) is a ship-mounted oceanographic instrument that collects pelagic fish eggs and ancillary data. The system operates continuously under nearly all sea conditions, providing a real-time estimate of the volumetric abundance of pelagic fish eggs from the surface to the instrument’s pump depth at 3 meters. CUFES is capable of drawing about 650 liters of seawater a minute into an egg collection chamber.
