a quick google reveals the entire absurdity of 'Carnis' note birds included as land animals.....
Why Is Fish Acceptable?
Per the USCCB, the Church’s laws refer to abstaining from “land animals” only. This includes the meat from chickens, sheep, pigs, cows and other forms of livestock — any animal, really, that makes its home on land. This also includes birds. However, because fish make their home in the water, the Catholic Church does not consider fish a meat. In fact, the laws of the Church go on to explain that followers may eat “fresh and saltwater fish, reptiles, amphibians and shellfish” on Good Friday, as animals that fall into one of these categories are not “carnis.”
It’s important to note that the rules for Lent and Good Friday were developed centuries ago, when meat was the food of celebrations. Back then, fish was not considered a “celebratory” dish, and so was perfectly acceptable to eat on a day of penance.
In today’s culture, however, the opposite is usually true.
