Hatching begins in the earliest of our egg takes. Starting with the Pinks and Chums, the eggs hatch into alevin. In nature, the alevin will remain in the gravel in the river, so, to simulate that, our alevin remain in the incubators. Over time the alevin will develop into fry. Once the fry are buttoned up (they have absorbed their yolk sacks into their bodies and the abdominal opening will seal), the fry are moved from the incubators and placed into the Capilano Troughs. At this point, the fry weigh around 0.5g.
