20 And God said, "Let the waters bring forth swarms of living creatures, and let birds fly above the earth across the firmament of the heavens." 21 So God created the great sea monsters and every living creature that moves, with which the waters swarm, according to their kinds, and every winged bird according to its kind. And God saw that it was good. 22 And God blessed them, saying, "Be fruitful and multiply and fill the waters in the seas, and let birds multiply on the earth." 23 And there was evening and there was morning, a fifth day.
24 And God said, "Let the earth bring forth living creatures according to their kinds: cattle and creeping things and beasts of the earth according to their kinds." And it was so. 25 And God made the beasts of the earth according to their kinds and the cattle according to their kinds, and everything that creeps upon the ground according to its kind. And God saw that it was good.

Commentary on Genesis 1:20-25
(Read Genesis 1:20-25)
God commanded the fish and fowl to be produced. This command he himself executed. Insects, which are more numerous than the birds and beasts, and as curious, seem to have been part of this day's work. The Creator's wisdom and power are to be admired as much in an ant as in an elephant. The power of God's providence preserves all things, and fruitfulness is the effect of his blessing.
