What does fingerling mean?
A fingerling is, most commonly, a very young or small fish — the word is used especially in fisheries science and aquaculture for juvenile salmon, trout, and other species at the stage when they are roughly the size of a finger. Hatcheries raise fingerlings in controlled conditions before releasing them into rivers and lakes to support wild populations or stock recreational fisheries. A second, culinary sense has become widespread: fingerling potatoes are small, narrow varieties with thin skins and dense, waxy flesh, prized for roasting and salads because they hold their shape when cooked. The word derives from "finger" combined with the diminutive suffix "-ling," literally suggesting something tiny enough to fit on a finger. Its tone is technical in fisheries contexts and gourmet-leaning in culinary ones, making it useful vocabulary for anyone interested in fishing, farming, or food writing.
A young or small fish, especially a juvenile salmon or trout, typically between the fry and juvenile stages.
"The hatchery produced over a million salmon fingerlings this season."
Used primarily in aquaculture, fisheries management, and angling contexts.
A small, slender variety of potato with thin skin and firm, waxy flesh.
"She tossed halved fingerlings with olive oil and herbs before roasting them."
Standard plural; used for both the fish and potato senses.
"The river was stocked with thousands of healthy fingerlings."
A fingerling isn't named after what it eats or where it lives — it's simply a fish small enough to slip between your fingers.

Etymology of fingerling
The word fingerling was formed in English from the noun "finger" plus the diminutive suffix "-ling," which appears in words such as duckling and gosling. It arose to describe fish so small they could be measured against or held between one's fingers, and it entered regular use in angling and fisheries contexts around the 19th century. The suffix "-ling" itself comes from Old English and Germanic sources, giving fingerling clear Germanic roots. Its later extension to small potatoes is a natural metaphorical borrowing of the same size idea.
How fingerling is actually used
In fisheries and aquaculture contexts, "fingerling" refers to a specific life stage between fry and juvenile, though exact size thresholds vary by species and region. The culinary sense referring to potatoes is common on menus in American English. Both senses carry neutral connotations.
