Solution

The correct option is D To cause breeding in fisheries
Hypophysation refers to the breeding of fish with pituitary gland extract. Injected pituitary gland extract bypasses the brain-pituitary link, acting directly on the ovaries and testes, providing the surge in blood GtH levels that normally precede spawning.
So the correct answer is option C.
