Tide-fed farms are best suited for:

Correct option is A

Correct Answer: (a) Traditional extensive system
Explanation:
→ Tide-fed farms rely on natural tidal exchange to supply nutrients and juvenile recruitment, so they suit extensive, low-input production where natural productivity is the main feed source.
→ Minimal artificial aeration or formulated feed is used in such systems.
Information Booster:
→ Conversion to semi-intensive requires control over water exchange, aeration and feed inputs beyond what tide-only farms provide.
Additional Information (Other Options):
(b–d): Require higher inputs, controlled water quality and often mechanical aeration not provided by simple tide-fed setups.
