ResumoDwarf herring (Jenkinsia lamprotaenia) was investigated because of its great importance in the Virgin Islands fishery and prominence as the base of the coastal pelagic food web. The species forms large spawning aggregations each month at predictable sites which allow for intensive harvest. Strong lunar periodicity in aggregation formation was documented. Dwarf herring appears to be a rapidly growing and short-lived clupeid. Reproductive size is approximately 40–45 mm SL with estimated L∞ = 62.4 mm and K = 4.5–5.5. No seasonality in biological characteristics was observed. Egg cannibalism was common in this species with eggs observed in 29.5% of conspecific stomachs.
