Order CLUPEIFORMES
Characters as under Clupeomorpha. Four families are
currently recognised (Nelson, 1984); Denticipitidae (one
species only) is known from freshwaters of Nigeria.

Small to moderate-sized silvery fishes (6-25 cm); body
fusiform, subcylindrical or strongly compressed, usually
with a keel of scutes along belly. Mouth more or less terminal; snout rarely projecting in front of mouth; maxilla not
reaching past eye; teeth minute or absent. Gill-rakers often
numerous, long and slender in most species. Fins without
spines. Scales cycloid, usually deciduous; no lateral line.
Pelagic, mainly inshore fishes, often forming large and
densely packed shoals which are heavily preyed upon by
fishes, birds and man. The clupeoid fishes (i.e. including the
anchovies) are the most important single group exploited by
world fisheries and in some areas they account for a third or
even a half of the total catch. The South African pilchard
fishery has declined markedly in the past 20 years; the pilchard catch has gone from 318 000 tons in 1960 to 35 000
tons in 1982. Juveniles of some species enter estuaries, and
the estuarine round-herring (Gilchristella) can tolerate
freshwater.

ern coasts. Identification is often difficult and may require a
microscope. In the fin formulae, lower case Roman numerals are used for unbranched soft-rays and Arabic numerals
for the branched rays. All warm-water species of the IndoPacific have recently been revised by Wongratana (1981).
Of the 13 new species of clupeid fishes described by
Wongratana (1983), only Etrumeus whiteheadi occurs in
our area.
