An unusual haddock caught off Unst may represent a ‘golden’ opportunity for fans of rare fish.
An albino, or “golden”, haddock was landed at the Lerwick fishmarket.
It was caught by local vessel Resilient while she was fishing about 45 miles northeast of Unst.
NAFC Marine Centre technician Leanna Henderson said golden haddock have no pigment in their skin, meaning that they lack the haddock’s normal colouration, including the distinctive black ‘thumb print’.
That leaves the fish almost completely white, but with a golden tint around its fins.
Very little scientific information is said to be available about the condition, but it is thought to be caused by a genetic abnormality that means that the fish’s skin cells don’t make any pigment.
The lack of colour hadn’t obviously affected this haddock too much as it had grown to a length of 56cm, as this photograph shows, and must have been several years old.
Golden haddock are very rare – no-one at the NAFC has seen one before, although a handful have previously been caught around Britain and Ireland.
