The International Training Center on the Methodology and Techniques of Research on Mackerel (Rastrelliger) was held from 20 October to 28 November 1958 under the auspices of the Food and Agriculture Organization of the United Nations and the Government of Thailand at Bangkok. In collecting data for length composition study several measuring boards were used. One of the handicaps encountered in field work was the necessity of assigning at least two individual workers in the sampling process, one who reads and sounds off the length of fish and another who records the measurement. When time is limited, this method is likely to cause errors.
An attempt to get nearly accurate data with the. least effort is submitted by one of the participants to the Rastrelliger Training Center for consideration as a standard equipment for measuring length of fish. A single worker can do the work of two individuals with a higher degree of accuracy in a shorter time.
This measuring board, the Philippine Fish Measuring Board, is designed to measure fish not exceeding 30 cm. A similar board for measuring longer fish can be constructed on the same principle.
