Again in the hatchery site, I had a very big luck for having free time, a borrowed microscope and some fries and eggs for observing them.
After spawning, the fertilized eggs had the maturation of embryo (eye pigmentation spots, developing of back bones, and organs), then after hatching the larvae has to reabsorbing the yolk sac whilst waiting the gastro enteric tube to getting ready for feeding and digestion. It was something absolutely great observing tilapias before they are grown up in ponds and lakes.
