Thread-Herring Identity
The species is Opisthonema medirastre. Older accounts sometimes included it under other Pacific thread herrings, especially Opisthonema libertate. Preserve the original identification and locality before assigning an older catch or size measurement to the modern species.
Nearshore Schools
Fish form schools close to the coast. Their position in the water column differs from a bottom-dwelling fish at the same location. A useful record retains the school’s coastal setting and, where available, depth and associated water conditions.
Food and Length
Crustaceans and pteropods are recorded foods. The compiled maximum is thirty centimeters total length, while a common-size entry uses standard length. Those endpoints differ, so the two numbers should not be compared directly without retaining the measurement conventions.
Keep Older Identifications Visible
A historical Pacific thread-herring name may cover more than one species. Preserve its original label and locality when reviewing records.
