Edible insects, which insects can be grown and eaten

They also write about the use of insect protein for baby food:

And since insect protein is present in baby food, it is known that baby food is often used by bodybuilders and athletes to gain muscle mass along with or instead of protein (from casein, for example).

Are insects really that nutritious? Although we are not surprised to eat crustaceans (lobsters, crayfish, crabs, shrimp) or shellfish (octopus, squid, oysters, grape snail)? As far as I know, these two groups of invertebrates have very nutritious and easily digestible protein, of dietary quality.

In general, I will immediately note for reasons of humanity-to cook alive like crayfish or fry in oil like cockroaches in Asia-is not worth it.

It is much more humane to freeze insects at -10...- 20C in the freezer of the refrigerator, and then make them into flour or minced meat. From which then form cutlets or sausages, meatballs.
And then subjected to heat treatment.

It will be more aesthetically pleasing and practical.

Here's another question: I decided to compare the effectiveness of using insect protein.
If a person weighing 70 kg needs 100 grams of protein per day, and the protein content in minced insects is 17%, then this means 0.588 kg of biomass is needed per day. Per year: 215 kg of biomass.
Using the rule of the ecological pyramid, insects need to feed 2150 kg of plant food per year.
It can be used for cricket: legume leaves, mulberry and acacia leaves, carrot and beet tops, nettle, dandelion, non-starchy vegetables (pumpkin), fruits (apples, pears), grain, wheat, legumes.

I want to compare it with a pig, for example.
But here is the question: for a pig, the protein content in meat and the feed coefficient (the mass of feed in kg that must be fed to the animal in order to get a 1 kg increase in biomass) are known. So, if you feed with mixed feed, the feed coefficient is 3, and the percentage of protein in meat
is 11-17%. That is, to supply protein to 1 person, you need 0.588 kg per day, 215 kg per year ( 2-3 pigs per year), 645 kg of mixed feed.
Naturally, the figures are too high, since a person can not eat 600 grams of fat pork per day, he receives proteins from other sources. But in our case, let it be a "spherical meat eater in a vacuum" that eats nothing but meat

Drawing analogies with carp (a poikilothermic animal that does not spend energy on maintaining a high body temperature), which has a feed coefficient of 1.5 to 3, depending on the quality of the feed, we can assume that in poikilothermic insects it is also somewhere around 1.5.
If we compare it with the meat of cancer, also an arthropod, then there is approximately 16 100% protein and lots of water, little fat and even less carbohydrates.
Then a person will need 0.625 kg of arthropod biomass per day, or 229 kg of biomass per year. Taking into account the feed coefficient of 1.5, we get about 343 kg of vegetable feed per year.
This is 1.88 times less than for a pig.

Questions:
1. What is the percentage of protein in insect biomass?
2. What is the feed ratio for herbivorous insects, such as crickets?

I offer cooperation on mass cultivation of edible insects. Premises and modest funding for the start-up are available. We need specialists who really have experience in this area. Location-nearest Moscow region, Russian Federation.
