koaro

Koaro, also known as *Koaro* or *Koaroa*, is a small, freshwater fish native to New Zealand’s lakes and rivers. Belonging to the family *Galaxiidae*, it is one of the country’s most iconic freshwater species and holds cultural significance in Māori traditions. Koaro are typically found in clean, flowing waters, often in lakes such as Lake Taupō, Lake Rotorua, and Lake Wakatipu, where they thrive in both cold and warm conditions.

Physically, koaro are slender, elongated fish with a slightly compressed body, reaching lengths of up to 30 centimetres (12 inches) and weights of around 500 grams. Their colouration varies, often featuring shades of brown, olive, or silver, with darker spots or stripes along their sides. They have a distinctive, slightly flattened head and large eyes, adapted for detecting prey in murky waters.

Koaro are omnivorous, feeding on insects, small crustaceans, and plant matter. They play a crucial role in aquatic ecosystems by controlling insect populations and contributing to nutrient cycling. Historically, Māori used koaro for food, with traditional methods of catching them, such as *kōrero* (a fishing technique using a long pole and net).

Conservation efforts have focused on protecting koaro from habitat degradation, invasive species, and overfishing. Some populations are listed as vulnerable due to threats like pollution and climate change. Efforts to restore native ecosystems and promote sustainable fishing practices continue to ensure the survival of this important New Zealand species.
