Heritage Open Day 7: Fisheries Research

The Great Ouse, the western boundary of King’s Lynn (on the other bank is West Lynn), is a commercial river, and the area has a long history of fishing. It was therefore both appropriate and very welcome that there was some exceedingly interesting and educational stuff provided by fisheries research people.

Not only did they lay on a full tour of their research vessel, in addition they had an exhibit featuring marine wildlife. Some of the younger folk were allowed to handle these creatures in carefully controlled circumstances. The featured image was also available to be taken away – a copy now adorns my outside table (and has survived a night’s rain).

One of the things that fisheries research does is monitor, and where necessary take preventive action, the proportion of juveniles that are being caught. Obviously, creatures caught while still juvenile are denied the opportunity to breed, whereas if they are only caught once they have already had the opportunity to breed future generations are protected.

What are the possible consequences of neglect? Well, when John Cabot first set eyes on the Grand Bank he had never seen such a preponderance of fish in a single location. Yet in 1997, 500 years (in natural history terms not even an eyeblink) after this, the Grand Banks Fishery closed for good – there were no fish left.

This was one of the most interesting and beyond a shadow of a doubt THE most important element of the day. My next post will feature another boundary marker, the Southgates, meantime enjoy a selection of photographs…
