A fingerling is a juvenile fish that is 10–15 cm, roughly the size of a finger. Fingerlings are extremely delicate, must be transported carefully, and kept and fed well to allow for a good harvest.
Using a nursery pond is a good way to grow quality fingerlings and boost your profit. This video from Access Agriculture explains the basics of the technique.
The video is available in English, French, Bangla, Bemba, Chitonga/Tonga, Hindi, Kannada, Nepali, Spanish, Tamil, and Telugu.
