11. Problems and obstacles Do not have previous academic research for these 2 species - Do not have researcher to collect data from field survey - DOF has a lot of things to do then cannot have time to collected data (no time, no budget, no staff and expert) - Do not go along with middle man (price will reduce due to touching can drop of quality of fresh fish meat) - The statistic data just only in catch (no length, weight, parameter and other biological data) - The Practical Workshop on Stock Assessments of Indo-Pacific King Mackerel and Narrow-barred Spanish Mackerel
