- Disinfection Dip for Broodstock Lobsters:
- Freshly captured spiny and slipper lobster broodstock (Panulirus homarus, Thenus unimaculatus) from natural marine reefs frequently harbor heavy fouling loads of commensal polychaetes, stalked barnacles, and fouling peritrich ciliates (Zoothamnium, Epistylis).
- prophylactic chemical dip in formalin ($100-150\text{ ppm}$ bath for 30–60 minutes, or short dip at $200\text{ ppm}$) rapidly detaches epibionts, ciliates, and polychaetes without injuring lobster gill filaments.
- Correct Option: Option 3 (Formalin).
