Fishery investigations began in September 1902 under the directorship of Walter Garstang. The work consisted of systematic exploration of the North Sea trawling grounds at different seasons of the year, together with studies of growth and migration of plaice "Pleuronectes platessa" based on tagging experiments, examination of the food of fish and the nature of the seabed. Detailed catch records from North Sea survey stations between 1902 and 1903 were summarised in a report published by Garstang in 1905. Research continued until
Ide (fish) of other cyprinids, but the larger adult fish form smaller single species groups which patrol what are believed to be regular routes.
