This has been going on for a looooooooooong time,
a square mesh section was introduced in the 80/90s (UK)
the idea being undersized fish could escape
it works up to a point?
FOREIGN boats are not bothered by size or by/catch if it is in the net then it will be on the market
( a visit to any FOREIGN ports will verify this)
Up & down the country undersized fish are being caught in large numbers,
on a daily basis by ??????so called anglers
bagged & taken home...
The old adage only take what you need stands firm
have a nice day all peaceful journies & tight lines to allllllllll
