The end of the line? Is this a film or an echo of the thoughts in my mind, somehow captured and recorded to be played to those that are prepared to listen to the truth that is unfolding all around us.

My name is Jason Hemmings, I am the managing director of a fishing company, Portland Sea Bass Ltd, that catches and sells seafood that is fished in a sustainable manner - by rod and line - direct to the customer.

We also dive for scallops picking each one individually from the sea floor whilst leaving their surroundings intact and unharmed.

I was invited to a screening of The End of the Line at which Claire Lewis, one of the producers of the film, was doing a question and answer session afterwards.

I would like to say that it was an eye opener but as a commercial fisherman I am all too aware of what is happening in our oceans and see the story unfolding in front of me every day.

I have only been a fisherman for three full years, this is my fourth, our main target species is the European Sea Bass. Currently this is not a pressured stock but in the not-too-distant future, it may well be.

If the fishing methods that are used to catch these fish by other fishermen, such as pair trawling, are not stopped, if politicians continue to ignore what they have paid their scientists good money to undertake and understand, if the policing of illegal fishing is not funded or they are not given the power to do anything about illegal fishing, if reserves are not set up, if closed seasons when fish are breeding are not introduced then the Sea Bass will go the same way that the rest of the fish are going - fish heaven. Which would be hell for all of us that depend on them for our livelihood.

We need to harness them not just harvest them.

Politicians find it hard to come up with solutions, they have to think about commerce - which is destroying our planet. They always act too late and the longer they leave it, the more the costs spiral and the less financially viable the solutions become.

Sometimes in politics dictators are needed just enough to get us back on the right tracks, so we can “do the right thing!” The dictator is… yep… that’s right… little old wise… you.

Start buying fish that is fished by sustainable methods, don’t buy fish that is endangered, buy fish that have finished their breeding season and are in season, so to speak.

Buy fish that belong to an accredited fishery. Ask where your fish comes from and what fishing method was used. If the person selling the fish doesn’t know, then don’t buy it.

If you stop buying fish and fish products that are not harvested in a sustainable manner, then the person catching them will not be able to sell their fish, their operation will not be profitable, they will either put their good head on and fish sustainably or go out of business.

If you stick to your guns you can make it happen. Don’t give in, be powerful, be part of it, be strong play your trump card and win.

You are trumps and the line is in your hand! What is at the end of it?
