The number of smelt fluctuated between years, with a marked decline since 2002, which has no obvious cause.
The movements of smelt shoals were difficult to follow.
In several large lakes the yield of smelt has been found to depend on ambient temperature (Nyberg et al., 2001).

If you're lucky enough to be in the right spot at the right time, smelt dipping can be as simple as bending over and picking up a dime on the sidewalk.
Dipping is not always that easy, however, as people often have to wade out in waist-deep water and still stretch to reach any smelt. That makes maneuvering those long-handled nets even more awkward.
The secret to smelt dipping, Roelle said, is to skim the net along just above a sandy section of river bottom where smelt have "balled up."
If you're banging against rocks on the bottom, that cloud of smelt will scurry away.
Roelle's group limited out in about two hours, sharing one net to accumulate 60 pounds of smelt, most of which were scooped out of the same spot.
Smelt in Lake Peipsi preferred large-bodied zooplankters in July and August, but from September onwards both large- and small-bodied zooplankters were selected.
Age 0+ smelt in Lake Peipsi mainly consumed zooplankton, especially cladocerans and copepods, and not rotifers.
