These gene-edited fish, pigs, and other animals could soon be on the menu:

The CRISPR gene-editing tool has been making headlines for the last 10 years, since scientists showed it could be used to easily alter the genome of a living organism.

[...] So perhaps it's no surprise that scientists have started experimenting with CRISPR in farm animals. One popular target is a gene called myostatin, which codes for a protein that controls muscle growth. Interfering with this gene can lead to muscle overgrowth. In other words, you end up with big, muscly animals. And, eventually, more meat.

[...] Research in fish is also well underway. Using CRISPR to target the myostatin gene, scientists in Japan have generated red sea bream that are bigger and heavier, with 17% more muscle than their unmodified counterparts, despite being fed the same amount of food.

And similar approaches have been used to beef up carp, tilapia, catfish, and other aquatic animals, including oysters. Other researchers are experimenting with different ways of using CRISPR to boost disease resistance or create salmon that make more omega-3.

You won't find CRISPR animals as products on supermarket shelves just yet. But some are remarkably close. In 2021, Japan approved the sale of two CRISPR-edited fish. One of them is the beefed-up red sea bream. The other is a tiger puffer fish that's also designed to be heavier.

The researchers behind the transgenic catfish are hoping they'll get it approved for commercial production in the US. But that could take a while. Only one gene-edited fish has so far been approved for sale in the US—and it took decades to get to that point.

[...] It's difficult to predict how quickly CRISPR animals will progress through the US approval process. But they are on their way.

    I hope they CRISPR up some rainbow guppies so I don't have to keep buying those salt water fish for cool colors.

    Just make sure never to name any of the CRISPR pigs Napoleon.

    But will it have the same effects we had with tomatoes? Where they got bigger and redder and generally taste like water now instead of tomatoes?

    What about the taste?

      Artificial flavors can be injected just before the fruits fully mature.

      Artificially flavored genetically engineered tomatoes!

        I thought artificially flavored meat was just called marinating?

          Maybe the taste of genetically modified tomatoes will ketchup to the taste of natural tomatoes.

      Don't worry, all meat will taste like chicken now.

        Did ChatGPT already win the fight, take over control of the earth and still didn't figure out what chicken tastes like?

      The flavor problem with tomatoes is that they are picked early and artificially ripened with vespene gas. Oops, ethylene gas.

    Stop screwing around with seafood and give me some genetically modified beef already.

    It will go amazingly well with all of the heavily engineered flavors present in a Big Mac.

    With all the seafood talk they'll next be telling us they can feed the whole world with plankton and issue an annual oceanographic report on this.

    A billion years from now, cockroach geneticists will look at the DNA record and see an anomalous surge in evolution which they will attribute to a rare meteorite strike that left behind a thin layer of microplastics. According to their theories, giant stupid hominids walked the earth but died in their own filth because they lacked the sophisticated societal traits of ants, termites and other higher species.
