Myxobolus cerebralis causes which fish disease?

Explanation:
Myxobolus cerebralis is a myxosporean parasite that causes Whirling disease in salmonid fishes. It mainly targets cartilage, especially in the head and spine, producing deformities and lesions that disturb swimming. This leads to the characteristic corkscrew or erratic movements and can stunt growth or cause mortality in young fish. The parasite’s life cycle involves an invertebrate host (often a tubifex worm), with spores released into the water that can infect susceptible juvenile fish. Other options refer to different diseases caused by unrelated organisms (bacteria or other parasites) and do not involve this cartilage-targeting myxozoan.
