Trevallies are the most abundant of them all, and you could find about 7 species of trevallies in Japan whose pars drift along warm Kuroshio Current.

Most of drifting pars won't survive the first winter, if they don't find their way back to Kuroshio Current or luckily manage to find and stay within warm water such as exhaust from power plant or factory. 2nd year fish grow larger than 40cm.
