Smolt


Definition:

  • (n.) A young salmon two or three years old, when it has acquired its silvery color.

Example Sentences:

  • (1) To examine the effect of long-term adaptation to ration and salinity, Atlantic salmon smolts were acclimated to three salinities (0, 10, and 30 ppt) and four ration levels (0, 0.2, 0.8, and 1.6% wet weight per day) for 6 weeks.
