Clupeiformes

 

an order of bony fishes. The body is usually silvery and laterally compressed. The pectoral fins are placed low, and the ventral fins are usually in the middle of the abdomen. There is a single, spineless dorsal fin. The fishes usually range in length from 5–6 to 60 cm and in weight from a few grams to 0.5 kg. Only a few species reach a length of 2–2.4 m. The scales are cycloid.

The order contains 15 suborders, embracing about 50 families. Amont the more important families are Clupeidae (herring), Engraulidae (anchovies), Salmonidae (trout), Thymallidae (graylings), Osmeridae (smelts), Daliidae (with the single species Dallia pectoralis), Chanidae (milkfishes), Esocidae (pikes), and Arapaimidae (with the single species Arapaima gigas). Some ichthyologists place a number of families into separate orders (for example, the orders Isospondyli and Haplomi).

The fishes of the order Clupeiformes are distributed in many seas and in some brackish and fresh waters. They are extremely important in commercial fishing, making up as much as one-fifth of the world’s fish catch.

Additionally, larvae within these families represent the 2 body shapes of larval fish, clupeiform (slender) and perciform (robust) that have been shown to influence susceptibility to extrusion (Smith and Richardson, 1977).
tricolor and others clupeiform fish indicate differences in salinity and temperature between environments.
The Hood Canal stock of Harbor Seals predominantly consumed gadiform fishes (64.59%), clupeiform fishes (50.89%), and salmoniform fishes (30.54% adult or unspecified, 3.74% juvenile) out of a total sample size of 7235 scats or stomachs.
On 2 December 2009 at 1309 h on the west side of Isla Tiburon, we observed a large (>1,500 individuals) group of blue-footed and brown boobies foraging on shoals of clupeiform fishes.
maculates fed mainly on clupeiform fish (anchovies and sardines), and less so on invertebrate species (shrimp and squid) (Naughton and Saloman 1981).
The anchovy (Engraulis encrasicolus), is a Teleostean clupeiform fish, a member of the Engraulidee family, about 6 inches long.
Food selective and diet overlap in larvae of Clupeiform species from central Chile.
Despite the high environmental heterogeneity linked to the upwelling circulation within Mejillones Bay, the distribution patterns of the coastal pelagic fish larvae in northern Chile usually show a direct relationship with high chlorophyll concentrations, since it shows high concentration (5 mg [m.sup.-3]) from coast to 20 km offshore (Yuras et al., 2005), in the same areas where spawning of clupeiform fishes occur (Morales et al., 1996).
Fifty-three species of fish were captured in 218 hauls at 34 fixed stations, with clupeiform species dominating.
In other clupeiform, such as Clupea and Alosa, it is more common to find undirectional polarity, where neuromasts have either cranial-caudal or dorsalventral polarity (e.g., Blaxter et al., 1983; Shardo, 1996).
Teleost fishes are represented by gadiforms, clupeiforms, oplegnathids, siluriforms, perciforms, beryciforms, and chimaeriforms (see Table 2).
