§ Sir A. SINCLAIRasked the Secretary of State for Scotland whether the experiments recommended by Lord Mackenzie's Committee to determine the relative efficiency of the Danish seine net and the trawl have been carried out by the Fishery Board: and, if so, with what results?
§ Sir J. GILMOURSome experiments have been made upon this question. A strict quantitative comparison between the Danish seine net and the otter trawl is difficult because they are generally used from different types of vessels and under different conditions. The Danish 2339W seine net is restricted in its use to the shallower and to the cleanest grounds and it can be operated successfully only during the hours of daylight. It is used only on the smaller steam vessels and on motor boats. The otter trawl is used on larger steam vessels. Subject to these remarks the experiments indicate that the Danish seine net compares favourably in efficiency of catching power with the otter trawl, and that the seine net allows a greater proportion of undersized fish to escape.
