The use of a large capacity portable pump for plankton sampling, with notes on plankton patchiness
A centrifugal pump with rated capacity of 400 gals./rnin. was used for plankton sampling in Puget Sound. With the ship under way, 50 simultaneous paired hauls were made with the pump and with a 0.5-meter nylon plankton net. The pumped water was passed through a special filtering unit with negligible damage to the plankters. Data show remarkable agreement between catches of fish eggs captured by pump and by tow net....
