Morphology

fish + louse

The meaning is directly compositional: 'fish louse' denotes a louse (a parasitic organism) associated with fish, so a learner who knows 'fish' and 'louse' can infer it. This follows a standard modifier+noun pattern common across languages; even if 'louse' often evokes mammals or birds, the phrase transparently signals a parasite that lives on fish.

Etymology

The noun fish louse is a literal name: the words fish and louse create the image of a tiny parasite clinging to a fish and feeding on its skin or blood. That's why it means 'a small parasite that attaches to fish and feeds on them'.
