The firm has blamed the closure on EU fish landing quotas and the decline of the fishing industry.
G&J Jack said in a statement: “For four generations, G&J Jack has been delivering high quality fish to customers throughout Europe.
“However, the decline in the industry has been significant over the last two decades, with the white fish sector in which G&J Jack operates being affected by reduced fish stocks and quota availability.
‘Tried various strategies’
“The Jack family, who owns and operates the company, have tried various strategies in order to sustain long-term trading and safeguard the workforce.”
The processor added that despite recent interest, attempts to sell the business as a going concern have proved unsuccessful.
The closure proceedings have been handled by chartered accountancy Meston Reid.
