The only diet study of little tunny in Colombian Caribbean waters is that of Moreno (1986): clupeoids (Harengula sp.
At family level clupeoids are still the most important prey item followed by carangids, but a number of fish families do not appear in 2003/2004 while mugilids were absent in 1986.
Herring, unlike most other
clupeoids, are total spawners with a group-synchronous ovarian organization (Murua & Saborido-Rey, 2003).
Sardine and other
clupeoids respond to oceanographic conditions, and, in the absence of predators and competitors, tend to aggregate near their prey in monospecific, epipelagic (ca.
Guelinckx J, Maes J, De Brabander L, Dehair SF, Olliever F (2006) Migration dynamics of
clupeoids in the Shede estuary: A stable isotope approach.
Growth of
clupeoids in tropical waters is faster and the life cycle is shorter when compared to temperate areas.
Xenomystus, have somewhat similar 'abdominal scutes', but "the abdominal scutes found in
clupeoids are formed as single median elements, whereas those of notopterids are paired, and therefore do not pass the test of similarity in the establishment of (primary) homology".
Year-Class Strength and Survival of O-Group
Clupeoids.
Within the coastal zone are found the big-eye scads, anchovies,
clupeoids, and half-beaks.
Clupeiforms showed distinct temporal, diel and tidal patterns, which is consistent with Modde & Ross (1981) results showing that
clupeoids vary more than percoids within 24 h period.
This dependency on
clupeoids, particularly Atlantic menhaden, has been well-documented throughout the range of striped bass (Walter et al.
Because trawling activities during PBSs were aimed at small pelagic
clupeoids, it was not possible to use CPUE data from these cruises to analyze spatial patterns in juvenile snoek abundance.
