Investors remain shaken by land-based salmon farmer Atlantic Sapphire's fish-die-off on Tuesday, sending the Oslo-listed company's share price down an additional 3.28 percent compared to Wednesday's close.

The company, which boasts the highest market cap within the land-based salmon farming segment, loss 500 metric tons of fish at its Miami facility, blaming the die-off on a "weakness" in its recirculating aquaculture system.

Other shares listed on the Oslo Stock Exchange also took a hit on the news, though the losses were much more modest.

Atlantic Sapphire's shares are currently trading at NOK 118 (€11.57/$13.64), setting the company's current value at NOK 9.52 billion (€934 million/$1.1 billion).

Around NOK 2.1 billion (€205 million/$242 million) has been wiped off the company's value in total since last week, after holding strong for the past few months.

"People become uncertain about how stable the operation will be in the future," Johannessen said. "The stock has been strong so far this year - when this happens you get a strong reaction down."

Johannessen refers to the incident as "one-off," citing the price dip as a "clear overreaction."

"In all biological production, one must reckon that something unforeseen happens, but that such a large proportion of production suddenly dies, I hope and believe that they will avoid that in the future," Johannessen said.

Pareto Securities keeps its 'buy' recommendation for the stock, with a target price of NOK 150 (€14.71/$17.33).

"However, it is obvious that the company must continue to prove that they will succeed in defending the share price," Johannessen said.
