Bangkok tuna prices back on the rise Hopes for lower tuna prices were dashed this week as a slight dip ended suddenly and Bangkok was back at more than $1,500 a tonne for skipjack. Fishing in the Indian Ocean should have been good, but vessels reported only yellowfin in quantity. Skipjack remains elusive with repeated concerns over sustainability. After a good start to the year - which prompted a slight easing in price - the western tropical Pacific region, which supplies Thailand, the Philippines and Indonesia, has tailed off. "If things don't pick up over the next couple of weeks we will be back over $1,600 a tonne," said a Bangkok source.
