Abstract

IN order to investigate the changes in the distribution of young fish in the Clyde sea area it was necessary to obtain on each of a series of dates numerous samples of the population over a large area. To cover this area it was necessary for the research vessel to travel at full speed for as much as possible of the time available. This precluded the use of conventional tow-nets or trawls at set stations. Further, an apparatus like the Hardy plankton recorder would filter too small a volume of water to catch a significant number of young fish. Sheard1 has described a net which appeared to be of the type required, in which the bucket is dispensed with and the tail of the net fliped (turned in on itself).
