I have to say I totally disagree, eel numbers throughout Europe continue to crash and taking elvers from the wild and stocking them into Loch Neagh & other waters for future netting and consumption is sustainable? Surely if Loch Neagh was a sustainable eel fishery there would be no need to top up levels from other sources, so denuding those sources of there brood stock. I think you will find that eels are abundant in certain waters, e.g. the lower Severn but overall in massive decline compared to historical levels.
Loch Neagh is stocked with elvers from farms - these are NOT elvers taken from the wild
many companies are now farming eels commercially by the way
i generally try to be polite to people but you are really pushing my limits
some eco systems are at risk and as such no commercial fishing is permitted - other systems are performing well and can sustain a level of commercial 'harvest'
its simply checks and balances
