Eel (Tuna)

The New Zealand longfin eel is a species of freshwater eel that is endemic to New Zealand. It is the largest freshwater eel in New Zealand and the only endemic species – the other eels found in New Zealand are the native shortfin eel, also found in Australia, and the naturally introduced Australian longfin eel. Longfin eels are long-lived, migrating to the Pacific Ocean near Tonga to breed at the end of their lives. They are good climbers as juveniles and so are found in streams and lakes a long way inland. An important traditional food source for Māori, longfin eel numbers are declining and they are classified as endangered, but over one hundred tonnes are still commercially fished each year.

Interactions & contraindications

May affect blood pressure

Watch for: Antihypertensive medications (ACE inhibitors, beta-blockers, calcium channel blockers, diuretics)

Combined use can push blood pressure too high or too low — monitor readings if you take blood pressure medication.

May thin the blood

Watch for: Anticoagulants (warfarin), antiplatelets (aspirin, clopidogrel), and other blood-thinning herbs or supplements (ginkgo, garlic, fish oil, vitamin E)

Combining blood-thinning substances can increase bleeding risk, including before surgery or dental work.
