Diagnostic Description
provided by FAO species catalogs
Can be confused with: The filamentous last dorsal finray distinguishes it from members of any other eastern Pacific clupeoid genus. Separated from other eastern Pacific Opisthonema species by having 63 to 110 lower gillrakers in fishes over 14 cm standard length (41 to 69 in O. medirastre, only 25 to 36 in O. bulleri; in O. berlangai there are 50 to 87, but it occurs only in the Galapagos Islands.
- Berry & Barrett, (1964 - taxonomy only) earlier works probably combined data for O. bulleri and O. medirastre, e.q.

Benefits
provided by FAO species catalogs
Of some importance as a live bait until introduction of purse seines for tuna. Contributed to the total Opisthonema catch in the eastern Pacific of 40 481 t in 1983 (the major part from Ecuador). The total catch reported for this species to FAO for 1999 was 60 999 t. The countries with the largest catches were Panama (38 746 t) and Ecuador (22 253 t).

Biology
provided by Fishbase
Usually occur near the surface of coastal and offshore waters, down to over bottom of continental shelf (Ref. 11035). Form dense schools. Apparently the most abundant of the eastern Pacific species of Opisthonema. Feed on phytoplankton (dinoflagellates and diatoms). Oviparous, with planktonic eggs and larvae (Ref. 35601). It is reduced to fish meal (Ref. 9291). Oil may be extracted (Ref. 9291). May be canned (Ref. 9291).
