Hosea 4:3

‘Therefore will the land mourn, and every one who dwells in it will languish, with the beasts of the field and the birds of the heavens, yes, the fishes of the sea also will be taken away.'

The consequence of all this will be that the land itself will suffer, and everyone in it will languish, to such an extent that it will have a major effect on the wild animals, the birds, and the fish. The affecting of the fish would appear to be an indication of heavy drought. Invasions usually pass fish by (unless, of course, the invaders are partial to fish). So the problems coming on Israel will be environmental as well as man-caused.

There may well be the intention here of pointing out that the people of Israel have failed in their responsibility for watching over creation (compare Psalms 8:7; Genesis 1:30). Even the creatures whom they are responsible for will suffer. It is as though creation itself is being reversed because of their behaviour.
