The Shetland registered Altaire which was involved in a £4 million pound black fish scandel 2 years ago has made its first landing of the new mackerel season. The Altaire (The largest UK owned pelagic vessel) landed 1900 tonnes of mackerel, reputed to be the biggest ever landing of mackerel in the UK for human consumption.

I quickly put 1900 tonnes into a tonnes to pounds converter and it comes out at 4,188,782 pounds. For examples sake if each fish weighed 1 pound that would equate to over
4 million mackerel on one boat.
Also worth a mention is the scale of the illegal fish landings by Irish boats over a 5 year period.
Following a series of police raids on Scottish fish factories in late 2005 more than 40,000 tonnes of mackerel, conservatively worth at least €48 million, was reported by the UK authorities to have been landed illegally by some of the largest Irish pelagic fishing trawlers over a period of five years.

www.fishupdate.com88,184,905 that's 88 million pounds. Again at a pound a fish its 88 million and that's just what was taken illegally.
So next time someone tells me to practice catch and release with this species please do not be offended when I lodge one in your rectal area ;)
