Abstract

During the last few years, the world-wide demand for fresh sources of protein has increased considerably and this has been a stimulus for the rapid development of the fishery for some of the pelagic fishes in the tropical and subtropical oceans. The scombroid fishes (mackerels, seerfishes, tunas and billfishes) constitute an important element of pelagic fishes, the annual world production of which has more than doubled, from about 0.93 million metric tons in 1948 to about 2.1 1 million metric tons in 1961. This quantum of increased production has naturally added to the volume of selected, preserved and processed fishery commodities of tunas and related fishes sold in the world markets during the last few years. In figures, from 301,000 metric tons in 1955, it has risen to about 420,000 metric tons (net product weight) in 1961 (FAO, 1960-61). A bulk of the increase in fresh catches as well as in processed goods mentioned above is constituted by tunas, the fishery of which has rapidly expanded during this period, and is being most actively pursued by Japan and the United States.
