stomach c~o~itents of the diffwcnt cdible shoal fishes. Occasionally
they form tho food of sardines iuid mackercls. From June to September
Acttes forms tho chief cliet of' the whitefish Lactarius sp. and the
lisirtail l'richiurus YI). Aiiii1,ysis of stomach contents revcals that
A. erythraew snd Lucifer ~ p p .
arc ctiitcn respectively by 18 and 16
out of the 2% spccies of fish off' the Travancorc coast (Nath, 1966).
The former species constitutes the major part of diet of the slenderscaled scad Salaroidps leptolppia (Cuvier), the golden scad Selar kalla
(Cuvier) anti the pointed-finticd
pike Sphyraenu mutipinnis Day
from Novomber to Mnrch, whereas the latter species is a particularly
importmt food item of such thretdfiri breiirns as Nemipterus furcosus
(Valcnricnncu) and N. jnponicus (Bloch) during January and February.
These two sergestids tire also the most common in the stomachs of the
common sprat Dussumieria acuta Cuvier et Valenciennes, the Russell's
scad Ilecupterus ruwelli (Ruppell) and the yellow-striped goatfish
Upeneus vittutus (Forskkl). Le Reste (1970) reports the similar finding
that A. erythwaeus and Lucifer sp. are major food items of larger
penaeids and young shore fishes in Madagascar.
Acetes juponicus in the Ariake Sea contributes the major part of
the diet of the taper-tail anchovy Coilia mystud (Linnaeus) (Suyehiro,
1942). Ikematsu (1955, 1963) reports that many penaeids such as
Metapenaeus joyneri (Miers) and M . monoceros (Fabricius) feed primarily
on A. japonicun ulong with the mysid Neompis japonicu Nakazawa
land copepotla. Imifer chucpi (as L. faroni) has been found to constitute
one of thc most important foot1 organisms of the adult Hawaiian
wchovy Nolephorus purpureirs Fowler (Hiatt, 1951 ).
I'leuroncodes plnnipes is very important in the diet of the albacore
TIwmrs (as GYemno) alnlungti (Ronnat,errc), the yellowfin tuna T. alhacares (Honnatcrre) (as Neolhunnus mncropterzcs) and the skipjack
Katuuiuonus pdamiu (Linnacus) off Raja California (McHugh, 1952 ;
Alvcrson, 1'363). According to Alvcrson (1 963), the stomach contents
of the yellowfin tuna from the region to the west of Raja California are
dominated by the Pkuroncodes: the average volumt: of the specir:fi
contained in each yellowfin stomach is about 0.5 1 (78% of the total
volume). Pleuroncodes monodon. constitutes the main diet of' the
Chilean conger eel Genypterus mnculatus (Techudi), representing a 75%
frequenry in the stomach (Henriquez and Bahamonde, 1964). The
species has been found on one occasion in the mouth of Merluccius
gayi guyi (Guichenot), a commercially important hake in Chile (Fagetti
and Campodonico, 1971). The adult and pelagic Glymothea stages of
Munidu gregnria have been known to be an important food of several
cetacelttis including southern right) humpback and sei whales. In
