It has been announced that Foyleport had a record £10 million in turnover despite the uncertainty posed by Brexit.
The Derry harbour, reports The Irish News, recorded an operating profit of £1.9m during 2018/19, marking its seventh year of consecutive growth.
The record turnover followed the port's handling of record levels of animal feed and fertiliser.
It means that all three of the north's ports have reported growth in the past year.
In June, Warrenpoint Port said its turnover rose by 5.5 per cent to £6.1m during 2018.
