Study Notes
Pāua Characteristics
- Pāua are ancient sea snails that haven’t evolved since the time of the dinosaurs.
- They have basic blood and respiratory systems.
- They breathe and reproduce through the row of small holes that runs along their shell.
Vulnerabilities
- Pāua are easily stressed and injured.
- Their only form of defence is to clamp down, which can take several days to recover.
- During this time, movement is restricted, making feeding difficult and increasing vulnerability to predators.
Circulation System
- Pāua have a unique circulation system where their blood doesn’t clot.
- They can bleed to death from the smallest cut.
- When injured, pāua try to stop the bleeding by contracting the muscle around the wound.
Handling Pāua with Care
- It’s essential to handle pāua with extreme care to avoid injuries.
- When taking pāua, they need to be carefully handled to survive back in the water.
Guidelines for Sustainable Harvesting
- Use a measuring gauge to ensure the pāua is not undersized (at least 125 mm for black-footed pāua in New Zealand).
- Always use a thin plastic spatula with no sharp edges to collect pāua.
- Perfect the technique of sliding the spatula underneath the pāua smoothly and quickly.
- Treat undersized pāua with extreme care and return them to the water carefully.
