Does sustainable fishing exist 2?

Tonight was the last of the BBC2 programme - The Fisherman's Apprentice. Monty Halls has taken the lessons he learnt from 8 months living in a small Cornish fishing village, including a spell of deep sea trawling and visiting US East Coast fishermen, to come up with a model of how inshore fishing can survive or even prosper.

Essentially, the fishermen started a 'fish box' scheme like a veg box. Punters don't know what they're going to get but must learn to wean themselves off the 5 species (cod, haddock, tuna, prawn and salmon) that accounts for 60% of fish eaten in the UK.

This can only be a good thing so it reduces the waste of edible fish which gets used as bait or chucked back dead and increases income for fishermen. It must also reduce the pressure on overfished species.
