Read this excerpt from a passage. Aquaculture is the science and practice of growing fish for food; in other words, aquaculture is fish farming. Like plant farmers, fish farmers oversee the natural life cycle of what they farm. Fish farmers "plant" (or hatch) their "crops" (fish) in " fields" (places called hatcheries) Farmers feed the tiny fish and protect them from predators. In aquaculture, as in agriculture, food is produced in a controlled environment rather than gathered from the wild.
