Closed containment – The future of fish farming

Thanks! Share it with your friends!


Closed containment is the future of salmon farming in B.C. Sea lice infestations, farm waste, disease and escaped farmed salmon could be distant, unpleasant …

Let’s not be driven by film footage from what are basically research
facilities, operating at densities far below commercial ones! If you
believe that open cage farms crowd the fish, then land-based units go FAR
beyond this. The sad truth is that land-based salmon aquaculture risks
replacing one bad system with an even worse one, from an animal welfare
point of view. In order to have any remote chance of being economically
viable, land-based systems will have to cram the fish in at several times
the density of cage farms. And in most climates, the tanks will be in
buildings, so the fish will spend their entire lives in factories. This is
NOT progress, this is regression to the worst kind of factory farming. We
need an answer to the problems inherent to open cage farming – but
land-based units for the fish’s entire life-cycle are not the best answer.
In my opinion, we should be pursuing the technologies which involve solid
floating cages/tanks, so that the farmed fish have at least some access to
natural elements such as seawater and daylight, but are protected from
becoming infected by sea lice & hit by diseases like AGD. Fish waste from
such systems can also be pumped ashore for treatment, rather than
discharged into the ocean. It also seems to me that such systems, with
their lower capital & running costs SHOULD have the potential to be
operated at more animal-welfare-friendly stocking densities. Raising fish
at densities of 100kg/m3? No thanks. Civilised nations should be leaving
intensive factory farming behind, not turning to it.

As long as you play the carbon game nothing is sustainable! Aquaponics is
very sustainable on a small basis. But we continue to move forward not
letting carbon foot print be the thing that controls our decisions for
making thing better. With new ways of doing things [ as long as greed and
power is not there] thing will get cleaner and more healthier.

lets stick to the facts says:

land based systems have been used for a long time with great success for
some species that have a high market value, and for specific life stages
such as smolt production and broodstock holding. However, there is no
proven success with raising Atlantic salmon to commercial production size
yet. these projects are R&D only. there is nothing wrong with doing R&D its
needed…but do not pretend its prooven to be viable. its not.

Some salmon that has been produced has been described as tasting different,
some say ‘buttery’ some say ‘muddy’…and its more expensive. Farmed salmon
is able to compete in the seafood section of your grocery store at current
prices…its already cost enough, who is going to buy it when the price
goes up because its tank reared…that may be fine for niche markets where
people will pay fro the novelty..but the average North America seafood
consumer wants lower costs , not higher. this is a scam to get people to
invest in R&D projects, and to make people believe that anti-salmon farming
activists are offering a viable alternative that the industry is jsut too
lazy and corrupt to take.

IF it is ever proven viable ,you can bet the industry will follow.

but what about in deep winter when everything gets frozen because the
containers seems to be outside and the weather is nice so what happened
when the temprature drops down to minus 30

GO AQUAPONIC!!!!!!!!!!!!

Dallas Weaver says:

Every analysis I have run says that net pens can economically beat recycle
aquaculture systems (RAS) in sustainability, especially the Carbon in a
life cycle analysis, and in large scale production costs.

That is reality. However, RAS for niche markets, broodstocks, biosecure
systems research species and producing fingerlings, where the value of the
product is much greater than food animals, you can afford the extra energy
consumption and make a profit. I know, I designed, build and operated a
totally closed RAS for three decades until I recently semi-retired and was
profitable every year.
