If successful, this could be amazing for fish stocks

very interesting article

It seems a nice idea but were do they get the food from to feed the fish in the farm, surely that will have to come from fish stocks that are already under pressure.

it would be a good idea if you could feed the fish on meat or veg atleast it would be sustainable

exactly takes 10lb of feed to put 1lb of weight on.

and your cod and tuna will most likely taste like carp the chinese wont mind if it swims lets eat it

Not necessarily true. It depends on species to species but even the ratio of 10:1 is vastly over exaggerated. 1.5:1 to 3:1 is more realistic

anything to back that up ,or maybe the end of the line is telling us lies

Just use economics to logic this out.

1 ton fish feed costs about €1200-1400 per ton.

Using 10:1 it would cost €12000 - 14000 of feed to produce 1 ton salmon.

Salmons worth about €6000 per ton tops to a salmon farm.

You can work out yourself what the convertion rate should be for farming to be economic. Remember to factor in cost of smolts, labour etc.

And yes some will say its un-economic and un-sustainable but pubs, hotels etc are closing we still have salmon farms.

The End of the Line is a great movie - don't get me wrong.


However in fisheries circles the findings of the team from the EOFTL have bben widely criticised and disputed (especially the collapse of global stocks by 2048 - however that is something I can believe given how stupid we are now. Just look at CITES and the Atlantic bluefin tuna this year). To my knowledge (and I have a particular interest in mariculture) the worst feed to weight conversion ratio is for tiger prawns at approximately 3:1. This however is unacceptable. In fact, anything above 1:1 is unacceptable - if mariculture is the future of marine fisheries production, it must represent a net gain in consumable biomass. Even farmed Atlantic salmon is not under this 1:1 ratio (however listening to to 'experts', you'd think it was). In all honesty, we have raped the oceans for all they are worth. we all better get used to jellyfish and carp sandwiches because at this rate we are shagged

i dont see the point to this. why would they need fresh water? its far harder to get quality fresh water than salt and they will nead to reclimatise the back to see water for offshore farms

It seems like a very good idea... Money talks eh.. they were offered 25mil before anything has even started

Money might talk, but not very smartly at times. People are still investing in companies that claim to have invented perpetual motion machines.

very good point, there is a global crisis on the availability of clean freshwater - remember our cryptosporidium outbreak - and these lunatics are talking about getting some of that into the desert of all places to grow modified saltwater fish - no bloody wonder we are doomed

when the last fish is caught men will realise they cant eat money

what I want to know is when the will invent the hoverboard like back to the future... the world would be a happier place with hoverboards
