April is when the constellation Leo becomes visible in the eastern evening sky.
Some kupuna (elders) believe April to be a productive month for planting, and in this month the malolo (flying fish) are running,
Ka iʻa hoʻāla i ka pō, wai lama i ke ahi
The fish that wakes people up at night and causes a glowing of torches over the water
Fishermen traditionally used torches (and now flashlights) to identify where the flying fish are skimming at the surface of the water. The Hano malolo technique was used to catch malolo, whereby a weighted fishing net was thrown where they were jumping out of the water.
April also welcomes the spawning of the moi (Pacific Threadfin) and the peak nesting season for the endangered ʻalae keʻokeʻo (Hawaiian coot), which lay five to six eggs in floating nest platforms near the edges of ponds.
