Unfortunately on the coast of the Pacific Northwest, specifically British Columbia, the salmon "farms are being completely shut down. Why? Lice and the excrement is seriously affecting the wild species of 3 types of salmon as well as the food for those salmon. The resident Orca whales are losing the salmon numbers due to the loss of salmon habitats and the production of vehicle tires made from plastics that contain 6PPD which, when in water and air contact converts to a deadly toxin for salmon and trout. Check out the materials in your own tires, find out what they're composed of, and realize that if they're plastics, your water systems have microplastics and ozone chemicals draining into water systems.

[@Saalor100]

FCR (Feed conversion ratio) is somewhat misleading. The "feed" is very different for the animals being compared. Fish needs a high protein content feed, while the protein content ( and sometimes moisture content) in the feed for other animals are different. Better to look at protein retention. This puts for example poultry on an equal efficiency as fish farming. If fed without fish meal, then you drastically reduce the harm to the marine environment.

[@TheKdcool]

Even better than that would be calculating calories per dollar or calories in calories out

[@DogeMultiverse]

FCR of 1 shown in the video seemed awfully suspicious. its like the fish don't poop at all to get a ratio of 1

[@Saalor100]

@@DogeMultiverse That is because the feed is dry, while the fish is not. If you would have taken the same feed, and added water to it so it would have the same water content as the fish the FCR would decrease as the weight of the feed increases because of the added weight of the water. FCR thus implies that "wet" feed is worse that dried feed, which is just ridiculous. This is what I mean that the measurement is very misleading.

[@FlyingDwarfman]

​@@Saalor100 I'm not proficient in the matter and won't claim to be. From the information here in this thread, I infer how dry feed is inherently better than wet in, if nothing else, shipping costs. The major factor in shipping of anything is density (weight relative to volume). If an animal feed is water dense, the reduced shipping costs for transporting it become huge. Add in that there is likely also no added cost or effort when the water is added back and that cost differential becomes even more significant.

[@Saalor100]

@@FlyingDwarfman I agree regarding the shipping costs, but the point of FCR is to measure how efficient an feed is converted into the mass of the animal. One flaw in the measurement is that it does not account for the feed composition or dryness. For example would it be more efficient to put effort in raising animals with an FCR of 1, when the feed is dehydrated waigu beef, or animals with an FCR of 0.5 where the feed is grass ( purely hypothetical). It is better to look on how well (mainly) the protein in the feed is preserved into the final product.

Hold. Up. this video started by saying "we're running out of land to produce food" and then suggested that we can grow this food within the ocean. I can't take anything you say seriously, now. For one, the issue with land optimization for farming is more complicated than that. It is intrinsically tied with how much airable land we are using to produce CERTAIN crops and livestock and the lack of rationality and research regarding the ratios of nutrients v. ressources to produce them. SECONDLY, the ocean is not an endless supply of marine life. Infact, we are depleting our ocean ressources at a MUCH faster rate than our land ressources as it pertains to food production. Without being clear, and direct about the differences between suistainable practices concerning the harvesting of marine ressources, and the limits of its capacity to solve our lack of systematic consideration for the optomization of food ressource extraction: you have started this video on blatent greenwashing langue du bois.

I would guess FCR is very different depending type of food an animal eats. Cows eat grass so they have to metabolize it to make protein for growth. Salmon eat fish meal high in protein.
