Data description on fisheries bycatch in the chub mackerel fisheries in China

    Chub mackerel (Scomber japonicas), bule mackerel and sardine fishes are key economic and
    ecological species in the Northwest Pacific Ocean. Most of the Chub mackerel and sardine
    catches were harvested by the lighting purse seine fishery in China. It need noticed that the
    Japanese sardine catch increased from a very low production in 2014 to a peak (266615 tons) in
    2022. Squid and saury are by catch or inevitable catch in the mackerel fisheries, and the annual
    output and proportion were very low whether in purse seine or trawl fisheries. The catch of other
    fish species such as pelagic species were also very low. Since it is not the main catch, it is difficult
    to make accurate statistics.
