A sustained solid margin into 2019 from lower tuna price volatility, the absence of further UK salmon plant losses, and a shallower loss for restaurant chain Red Lobster will drive strong full year core profit growth for Thai Union this year, according to analysts from Bualuang Securities.

"We expect raw tuna prices to mostly stay in the $1,300 (€1,144) to $1,800 (€1,584) per metric ton range this year," said Prasit Sujiravorakul, an analyst at Bualuang Securities in an update.
