German frozen seafood giant Frosta saw earnings slide in the first six months of the year as the company suffered from higher salmon and vegetable prices.

Earnings plunged 59.4 percent to €4.99 million ($5.6 million) from €12.3 million ($13.7 million) a year earlier.

Revenues, meanwhile, were 3.8 percent higher at €262.7 million ($292.3 million).

In May Frosta said it expects to post low single-digit growth in 2019 thanks to increased demand for its ready meals and the launch of its "Frosta Fit" low-carb range.
