Histories

Fish that go in schools are seldom born in rivers; they are raised in the lakes, and this is how they behave: when the desire of spawning comes on them, they swim out to sea in schools, the males leading, and throwing out their milt, while the females come after and swallow and conceive from it.

When the females have grown heavy in the sea, then all the fish swim back to their own haunts. But the same no longer lead; now the leadership goes to the females. They go before in a school as the males had, and now and then throw off some of their eggs (which are like millet-seeds), which the males devour as they follow. These millet-seeds, or eggs, are fish.
