You seem to be getting things a bit mixed up. Yes "Lobe fins" are paddle like fins. The more primitive (prehistoric) fish like the Coelocanth and the Australian Lung Fish have pectoral fins described as "lobed fins". However these have absolutely nothing to do with "milt". Milt is the name given to the substance spread by male fish to fertilise the females ova (eggs). It is the equivalent of sperm in mammals.
The main difference between lobe-finned fish and ray-finned fish lies in their fin structure. Lobe-finned fish have fleshy, lobed fins supported by a bony structure, while ray-finned fish have fins supported by bony rays. Additionally, lobe-finned fish are believed to have given rise to tetrapods, including amphibians, reptiles, birds, and mammals.
Perch are lobe-finned. The fins on Perch fish are fairly rounded and distinct for this species of fish in the wild.
A goldfish is a ray-finned fish because its fins are supported by bony rays. Ray-finned fishes belong to the class Actinopterygii, characterized by fins made of webs of skin supported by bony spines or rays. This differs from lobe-finned fishes like lungfish or coelacanths, which have fins with a fleshy, lobed appearance.
