Hi guys!
How are you doing?
Welcome back to Fisholover Issue.
Today I'm going to talk about a few myths surrounding fish farming industry
that we always hear about these days.
The controversy about eating wild over farmed fish
will hugely impact the future of aquaculture industry.
Media have been bombarded with these issues
and influence the consumer without any justified facts.
So, we as a consumer should be aware of this myth,
study the sources and not only spread unnecessaries rumors
that we find on social media.
So without further ado let's get started
[Low Omega-3 in farm salmon]
Salmon has been one of the excellent source of Omega-3 fatty acid,
undoubtedly.
Compared to other fish species,
salmon has been number one choice for Omega-3 fatty acid.
Omega-3 fatty acid extracted from salmon is dependent on what they eat.
Wild salmon has high Omega-3 fatty acid due to their high diet range
from algae plankton and small fish surrounding them
On the other hand,
farmed salmon get their doses of Omega-3 fatty acids from the pelleted feed given to them
These pelleted feed may contain fish oil and other types of plant oil.
Many aquaculture producers today limit the amount of fish oil that goes into their fish.
The use of plant oils such as canola oil and marine algae oil are emerging
due to the presence of Omega-3 fatty acid in these ingredients.
However, the feed containing canola oil
has a shorter chain of Omega-3 than the ones in fish oil,
which is more beneficial for human health.
So to ensure that Salmon
gets sufficient amount of Omega-3
and reduced the use of fish oil,
feed containing canola oil
will be fed to the salmon throughout their lifetime
and fish oil feed will only be fed before the farmers
send their fish to the market.
So by using this practice,
farmed fish contain more or less the same amount of
Omega-3 fatty acid compared to the a wild counterpart.
Besides canola oil, marine algae oil is highly promoted today as replacement for fish oil.
Wild fish that processed into fish oil
contain high Omega-3 fatty content
due to the presence of EPA and DHA
from the marine micro-algae that they consume.
So, using marine algae oil should be a great way
to take the pressure off from fish oil,
while producing highly nutritious sustainable ingredients for aquaculture.
[Dyed Pink Flesh Farmed Salmon]
Pink flesh salmon is a necessity in the salmon industry.
Without this pink fillet, no one will know that
that's salmon they're eating.
Would it be appealing if your salmon flesh colour is white?
I don't think so
Some misconception about the pink colour in salmon fillet
is the use of dye injection to enhance the colour.
The fact is,
both wild and farmed salmon get their pink meat colour
from what they've eaten, called Astaxanthin.
The wild salmon will consume more crustaceans,
algae and seaweed as their natural Astaxanthin producers.
So, similar to Omega-3,
Astaxanthin also were obtain from the algae for example
Spirulina, Haematococcus and Dunaliella.
Farmed salmon has been supplied with feed
that contains carotenoid pigments
containing chemically synthesized astaxanthin from many sources
similar to what the wild salmon have eaten.
So, obviously this carotenoid pigment is not dye though
Either way, the same source of Astaxanthin is included
in both diets of farmed and wild salmon,
making them pink as we've seen them today.
[Tilapia Worst Than Bacon]
This claim about farmed tilapia is widely circulated over the internet a few years ago.
The unfounded facts indicated that tilapia contains
high level of Omega-6 fatty acid and low Omega-3
making it worst than bacon.
In reality, the nutrient level of fish is based
on what they've consumed as I've said earlier.
Although tilapia has lower Omega-3 fatty acid than salmon,
it is comparable to both cod and catfish.
It is true that tilapia has a higher ratio of Omega-6 to Omega-3 fatty acid with the ratio 4:3
but the amount of Omega-6 is too low to be an issue,
which is 0.5g per serving.
In fact, this amount is lower than other healthy sources such as nuts and seed
and more junk food such as chips, cookies and fries.
So, the issue with bacon appeared when it is fried.
The greasy bacon may contain a whopping ratio of 10:1 of Omega-6 to Omega-3 fatty acid.
So, clearly it is unjustified to compare tilapia to bacon as essentially.. tilapia is less inflammatory than bacon.
[Tilapia Contain Dioxin]
What is Dioxin?
A Dioxin is a group of contaminants,
which get carried away into the water through the land contamination.
So if we think thoroughly...
How could only tilapia be affected with Dioxin
if there are many other fish living in the water?
So, Dioxin will affect every organism in the water not only tilapia.
In reality, the presence of Dioxin appeared to be observed in wild-caught fish as well as farmed fish.
There are tilapia cultured in recirculation system or aquaponic system,
which are more healthier and not exposed to any harmful contaminant.
So, this claim that all tilapia contain Dioxin must be fabricated!
As far as Dioxin is concerned,
a study from National Institute of Nutrition and Seafood Research (NIFES)
reported that; a higher concentration of Dioxin in wild salmon was observed than farmed salmon.
The same findings also applied to other contaminants including Polychlorinated Biphenyls (PCBs) and Mercury.
Despite these level of contaminants in both wild and farmed salmon,
the researchers still recommend both fish to the consumer as they are not alarming levels.
[Farm fish need protein from wild fish]
So generally speaking, this statement might be true 20 years ago.
As in today, even for carnivorous fish such as salmon,
the highest feed conversion ratio ever recorded is 2:1.
Two kilos of wild fish; to produce 1 kilos of farmed salmon.
But, that was unlikely to occur now.
Many major salmon producers are able to produce less FCR level at 1:1.
That was so much lower than beef and swine,
with 6:1 and 3.5:1 respectively.
Wild fish caught to feed farmed fish is processed into fishmeal.
The use fishmeal from wild fish in farmed fish has been extensively reduced
due to the unsustainable factor.
Many feed producers already opt for more sustainable ingredients
for protein source in aquaculture to replace fishmeal from wild caught fish.
However, to get rid of fishmeal altogether is impossible.
In fact, according to IFFO (Marine Ingredients Organisation),
around 35% of fishmeal today is produced by using recycled byproduct
and waste from fish processing.
By removing all fishmeal in fish feed would compromise fish health
and close the environmentally friendly way of recycling fish waste products.
More sustainable sources such as algae, insects, and single cell organism
are well-documented to be great alternative for fishmeal.
To produce this ingredient today are comparatively much expensive than using fishmeal entirely,
So we need more time..
However, it could take some pressure off the fishmeal
with the significant increase in technological advancement in the fish feed industry,
there are no reasons why we shouldn't be able to reduce the cost of production for these ingredients in the future.
So guys, that's all.. the most common myths that I've frequently heard about aquaculture
that I thought, well I should talk about this
So, if you happen to know any other myths that I've not stated here,
please feel free to share them in the comment section
and leave a review about what I've just discussed.
So.. do you agree with those statements? yes? no?

So with that, thank you for watching
and see you next time!
