The planned transaction, valuing Scottish Salmon at 517 million pounds, will allow Bakkafrost to cut production costs by utilising greater economies of scale at a time of declining salmon prices.

Both companies are listed on the Oslo Stock Exchange, a unit of Euronext.

To fund the purchase, Bakkafrost plans to sell 7.33 million new shares to investors, which, if sold at Wednesday's closing price, would raise some 3.87 billion Norwegian crowns (346 million pounds).

DNB Markets, Goldman Sachs International and Nordea were appointed to lead the share issue, Bakkafrost said.
