Re: Food! - Marsians=vegetarians?

Sadly, fish farming is very problematic where you don't have copious amounts of fresh water to constantly replenish the "farm". If you had to completely clean and recycle the water, it would become very resource intensive and there is the risk of diseases passing to humans.

I agree that, for the foreseeable future, plants are the way forward, with innovative foods like the Impossible Burger being made use of.
Then we also have the possibility of cultured meat from stem cells. That would seem a more sensible meat product for Mars. The technology is not quite there yet, but there's no reason to suppose it won't be in 30, 40 years' time. Of course, if your Mars pioneers really can't do without their meat then bringing it in frozen in vacuum packs - meat will last 2 to 3 years.

That's one great reason not to bring animals to Mars, at least not initially.
Besides, being vegetarian isn't all that bad noways. If your hungry for meat, you can always go cook up the Impossible Burger.
As an added benefit, it's way less wasteful to be plant based. For every 1 calorie of beef you get from a cow, you have to feed that same cow approximately 8 calories of food. Meat isn't evil, but it definitely isn't the most efficient form of food, and I doubt it will be a luxury that the future Martian people will be able to afford any time soon.

Edit: I forgot to mention fish as an exception. If aquaponics ends up being used to grow food on Mars, than the colonists will get fish to eat, since fish are an integral part of aquaponics and you may as well eat them if you've got them.

Re: Food! - Marsians=vegetarians?

For Louis re #201

Thank you for the caution about adequate cleaning of water for fish farming.

I think you may be missing something, and your remark here helps to allow for an opportunity to bring it out.

In a closed environment, water for sure, and (probably) everything else must be cleaned thoroughly and regularly.

Earth is a closed system taken as a whole, but it is so large we humans often think of it as open.

The Earth provides processes to thoroughly and completely clean water (and everything else) but while those processes require vast amounts of solar or nuclear energy (at the core of the Earth) we human don't pay the bill, so we don't think about it.

On Mars, we must certainly WILL be paying the bill.

You are free to place the lives of your family at risk by depending upon solar power to meet your needs, but most of the settlers (or potential settlers) I know will want to be sure they have a nice warm nuclear fission reactor at the heart of their community to keep the lights on, the air and water clean, and everyone healthy.

Re: Food! - Marsians=vegetarians?

I have a local fish hatchery near by and the fish are used to restock rivers and lakes to which as a the deseased fish which happen are moved to other tanks further from the group which is to be used to restock with. I think the desease fish occur from contaminants in the water source and from the foods used to feed them as its just moving water from the lanks that are used with in the tank areas which are open to the surrounding environment.

Re: Food! - Marsians=vegetarians?

Plant-Based Doesn’t Always Mean Healthy; You may want to reconsider a plant-based diet if your motivation is health.
But other than canned or frozen, dehydrated we are going to only have meats that are in only short lived for the most part.

These dishes do look go thou

So what is so wrong with a plant based menu?

plant-based meats are often high in sodium, ultra-processed and not any healthier than the meat they imitate.

Impossible Burger, for example, is an impressive meat-free mix of soy, potato proteins, coconut and sunflower oils.

grocery stores are taking note, featuring an array of burgers, sausages, nuggets, ground meat and seafood options all without any trace of animal products.

Singapore Institute for Food and Biotechnology Innovation modelled the outcome of replacing bacon, chicken, beef burgers and ice cream with animal-free versions.

Is the issue is nutrition?

plant-based alternative were below the daily recommendations for vitamin B12, calcium, potassium, zinc and magnesium, and higher in sodium, sugar and saturated fat.

Plant-based meat alternatives lacked certain amino acids and derivatives, like creatine, taurine and anserine, “which can all have an impact on our health and potentially brain function as well as muscle function,
