Natural food and fish feeds

Abstract

Rearing fry and fingerlings is to nurture 3 or 4-day-old postlarvae, which start to eat food, into fingerlings for stocking in grow-out ponds. It is generally divided into two stages: at the first stage, fry are cultured for 18–25 days to a body length of 3 cm. At the second stage, fry are reared for another 3-5 months to fingerlings with a body length of 8-20 cm. Most of the grow-out ponds are stocked with fingerlings, but sometimes with some two-year-old fingerlings. [Extract]
