The Faithful Shepherd says that fish and locusts are permitted to be eaten because they can be gathered without slaughtering. He says this is like the sages of the Mishnah, that do not need to be killed by the Angel of Death, but are gathered up. And just as the fish live in the sea and die if they are taken out, the students of the Torah die if they are separated from the sea of the Torah. We learn that the Kabbalah sages are above all, and that they have dominion over the fish of the sea and the birds of the air. Moses says that if a younger student who is not yet fit to teach goes out and teaches, he must die. He also speaks about the sages of Mishnah as being crocodiles and talks about what happens when they disagree.
