Here are the top business stories making the headlines in the morning newspapers.
£17.5million boost for fish trading venture
North-east seafood entrepreneur Joel Watt's fish trading platform Rooser has raised £17.5million of capital funding to scale up.
The funding round was led by Index Ventures, which has previously backed Etsy, Farfetch, Deliveroo and Just Eat. Google Ventures and Point Nine Capital also took part.
Rooser plans to use the cash to advance its mission to eliminate seafood waste and improve transparency of the fish supply chain.
The Press and Journal says the firm's innovative trading platform reduces friction for seafood buyers and sellers by combining stock management, a sales tool and access to a real-time, online marketplace.
Rooser currently facilitates seafood trading across more than 250 companies and in 13 European countries.
The business was launched in 2019 and is led by co-founder and chief executive Joel Watt, a graduate of Robert Gordon University.
Mr Watt started his career in accountancy roles with PwC and Bibby Offshore, and more recently spent six-and-a-half years as a director of Fraserburgh fish processor Jack Taylor.
Russia accused of blackmail
Russia's decision to cut off gas exports to Poland and Bulgaria is an "instrument of blackmail", the EU says.
European Commission president Ursula von der Leyen said the move showed Russia's "unreliability" as a supplier.
But the Kremlin said Russia had been forced into the action by the "unfriendly steps" of Western nations.
The BBC says Europe depends on Russia for more than a third of its gas needs, and state energy giant Gazprom holds a monopoly on pipeline supplies in Russia.
Fears that more businesses will go from heart of Aberdeen
An Aberdeen businesswoman is warning of more city-centre closures to come as she shuts her Union Street hair and beauty salon.
Julie Hulcup has battled to keep The Collective afloat since the pandemic crippled trade.
But the Press and Journal reports that, after overcoming obstacle after obstacle, her recent business rates bill proved to be the final straw.
Faced with a monthly tax of £1,900 on the Granite Mile premises, she has thrown in the towel -relocating to her smaller Collective on the Corner on Diamond Street.
Ms Hulcup said the salon suffered a death by a thousand cuts over the last two years.
It comes after the Nail Co salon and Bravissimo lingerie shop closed in recent weeks, creating more unsightly vacant units on the once-thriving thoroughfare.
Ms Hulcup fears more Union Street businesses could soon go the same way.
She said: "The number of places closing is unreal, and I think there will be more. Other businesses will be feeling the effect of these new rates."
Serious Fraud Office at Liberty Steel
The Serious Fraud Office has visited the offices of Sanjeev Gupta's Liberty Steel, demanding information.
The BBC says the SFO launched an investigation into suspected fraud and money laundering by parent firm GFG Alliance last May.
GFG owns a collection of businesses in energy, steel and trading, employing about 35,000 people, including thousands of staff in the UK.
Mr Gupta, its executive chairman, came under scrutiny after GFG's main lender Greensill Capital collapsed.
The finance company went under after its insurer refused to renew cover for the loans it was making. It was the main lender to GFG's Liberty Steel, which employs 3,000 people in England, Scotland and Wales.
Once described as the "saviour of steel", SFO officers visited addresses linked with Mr Gupta's operations on Wednesday and requested documents including company balance sheets and annual reports.
Air Force One deal is expensive for Boeing
Former US President Donald Trump's new deal for Air Force One was a bad one for Boeing, the plane-maker's chief executive has said.
Dave Calhoun spoke as the firm said it expected to lose £875million on the two planes for the White House.
The BBC says Mr Trump had forced the company to renegotiate its contract, calling the initial deal too expensive.
The new agreement made Boeing, not taxpayers, responsible for changes to costs.
"We took some risks not knowing that Covid would arrive and not knowing that inflation would take hold like it has - and both of those have impacted us fairly severely," Mr Calhoun said on a conference call with investors on Wednesday.
