Canadian shellfish giant Clearwater reported an increase in earnings in the first quarter of 2019 despite flat sales.

Earnings before interest, taxes, depreciation, and amortization (EBITDA) was CAD 20 million (€13.2 million/$14.8 million), up 4.7 percent from the same period a year earlier.

Sales over the period flat lined at CAD 120 million (€79.5 million/$89.1 million).

The improvements in earnings are a result of a better sales mix, heavier on high-margin species, and lower operational costs, the company said.
