Answer 2

Catla and Rohu are freshwater bony fish.

Explanation:

Fishes are classified into two groups: Bony fishes and Cartilagenous fishes.

Bony fish have bony endoskeleton while cartilagenous fish have an endoskeleton predominantly made up of cartilage.

Bony fish have gills covered with operculum while cartilagenous fish have gill slits not covered with operculum.

Bony fish have four gills and air bladder but cartilagenous fish lack lungs or swim bladder.

Bony fish have mesonephric kidneys while cartilagenous fish have opisthonephric kidneys.

Excretion in bony fish is ammonetelic while excretion in cartilagenous fish is ureotelic.
