The exploitation of pelagic shoal resources off South Africa’s west (Atlantic) coast began during the second world war, with large-scale expansion beginning in 1947–49. At the end of the forties, the Government lacked the scientific evidence to formulate effective conservation policies, and pending the outcome of the research programs it deemed it advisable to put a brake on the expansion of these fisheries.An obvious measure was a ceiling on the annual catches. But this would not necessarily have prevented further influx into the fishing or the processing phases of the industry. As part of an economy-wide practice to require licenses for various kinds of operations, these were required for all fishing boats and factories. The Government decided in 1949 to refuse the issue of licenses for additional fish-processing factories and to limit the number and capacity to those already in operation or under construction.In 1953 the fishermen, aware of the limitation on the outlets (factory intakes) for their catches, and the continued influx of outsiders into the flourishing fishing side, willingly agreed to the freezing of the number and hold capacity of vessels fishing for pilchards and maasbankers. After the enactment by parliament of the necessary enabling laws, regulations were issued to establish a Pilchard/Maasbanker Boat Limitation Committee consisting of government, factory, and fishermen representatives to apply the controls over the number of boats, their hold capacity and the allocation of this fleet to the various factories.Adjustments, including some increases in the capacity of the fleet, were made from time to time to cope with changing conditions in the resource.A serious weakening in the control system occurred when fishing and processing licenses were granted to operators of fishmeal factory ships.The results of the limitation of entry into the fishing phase and the processing phases include several significant trends, among which are a smaller number of boats, larger-size boats with more powerful engines and equipment, and increased factory-ownership of boats. The factories introduced stickwater plants and other processes to increase the yield of meal from the available tonnage of raw fish.Although the industry has experienced difficult periods, it nevertheless seems, broadly viewed, that through the policy of restricting entry at the early stages of the new industry, it acquired sufficient resilience to cope not only with the ups but also the downs. It appears doubtful that "overcrowded" fishing and processing sectors would have had sufficient resilience to face fluctuating catches and fishmeal prices.
