Pre-tax losses at Dawnfresh Seafoods have more than doubled after it unexpectedly had to pump cash into the Scot Trout business it acquired in April 2008.

Pre-tax losses at Dawnfresh the largest supplier of frozen and fresh trout in the UK rose by 108.2% to £9m in the year to 31 March 2010, accounts filed last week at Companies House show. This came despite a marginal rise in sales to £50.5m.

Scot Trout had required "significant capital expenditure" to address working standards, processing requirements and technical concerns, said Dawnfresh chairman Alastair Salvesen. The cold winter had affected fish growth rates and mortality, he added.

Salvesen predicted that Dawnfresh, which had a new management team with five new directors hired in the past 18 months, would be in profit in 2011, despite the challenges of pushing through higher trout prices.
