A study by the National Institute of Fisheries Science in Korea estimates the potential anchovy production in the Korean sea to be 100 million tons, with current resources at 16 million tons. However, the article highlights the need for caution in estimating marine life, as it is more complex and uncertain than population or economic forecasting. The article criticizes the use of unverified biological and ecological information to estimate resources and points out the underestimation of resources due to climate change and a decrease in phytoplankton, a food source for anchovies. It emphasizes the importance of minimizing uncertainty in resource estimation and suggests using advanced technology and equipment to obtain more biological information to calculate resources more accurately.
