Sea Fever - last in the series and this week - Gone Fishing!

if you missed it - don't worry - head off to the BBC iPlayer and catch the latest episode of Sea Fever - which this week took a look at the fishing through a mixture of archive and contemporary footage - much of the old and new footage from the far end of Cornwall ans St Ives in particular.

Eagle-eyed viewers with a knowledge of fishing will no doubt spot the occasional discrepancy between the commentary and the footage of gear, boats and places.

Many will also feel moved to comment on the age at which some of them first went to sea on their father's boats - as young as seven - and all without the now mandatory Sea Survival, Firefighting and First Aid Certificates - but that was then and this is now!

The series which focuses on Britain's maritime history, culture, economics and science concludes with the remarkable story of Britain's fishermen, using home movie archive.

At the beginning of the 20th century thousands made a good living working in conditions of unimaginable danger. But technology and avarice in some areas created problems of over-fishing and the century ended with the port of Hull laid to waste. Hull skipper Ken Knox and filmmaker/engineer Alan Hopper watch Alan's astonishing films and tell how the sophisticated technologies companies used to send crews to distant Atlantic waters in the 50s and 60s in the hunt for white fish. Hull's men had already fished out local waters using a technique called box fleet fishing, a dangerous method remembered by one who did it in the 1930s, Robert Rowntree.

Smaller ports survived and small scale family fishing was part of the secret of their success. In Peterhead, Donald Anderson filmed the exploits of his crew, including his young son, as the fleets hunted herring shoals.

In St Ives, the Stevens fishing family were filmed by a local film-maker on their boat the Sweet Promise back in the 1950s. Watching this film today is David Stevens, the son of the skipper and 15 at the time, and crew member Donald Perkin, the last of six brothers who worked as fishermen in St Ives from the 30s to the 80s. There is footage of David Stevens Jnr at sea today on the family boat Crystal Sea II.

Historian from the National Maritime Museum in Falmouth, Tony Pawlyn, helps explain how these men fished and why they survived while the Hull men went under. These men are our last link with a tradition of hunter-gathering.

The programme goes to Skye in Scotland and asks if the new way of fishing - farming - is the ultimate threat to livelihoods of these hunter-gatherer fishermen.
