■ A SLUMP in prawn sales during the pandemic knocked sales at the largest division of aquaculture group Benchmark Holdings.

Annual turnover in Benchmark’s advanced nutrition business fell by a fifth to £59m as people around the world have eaten out less frequently this year.

Revenues across AIM-listed Benchmark fell 15pc to £106m in the year to September.

Benchmark shares fell 5.3pc, or 3p, to 54p, but are up 25pc so far this year.
