Engraulis anchoita Hubbs & Marini 1935

Body slender, oval in cross-section, its depth about 5.5 times or more in standard length. Snout prominent, pointed, about 3/4 eye diameter; maxilla moderate, tip bluntly tapering or a little rounded, reaching to front margin of pre-operculum, extending a little beyond tip of second supra-maxilla; teeth in jaws small, numerous. Lower gillrakers 38 to 45, long and slender; no gillrakers on hind face of third epibranchial; pseudobranch long, reaching onto inner face of operculum. Anal fin short, with iii 17 to 20 finrays, its origin a little behind base of last dorsal finray. A broad silver stripe along flank, disappearing in adults. Anchoa marinii also has a long pseudobranch and just overlaps in anal finray count, but anal fin origin below midpoint of dorsal fin base; A. filifera and A. lyolepis have a long pseudobranch and a posterior anal fin origin, but like A. marinii have a longer and more sharply pointed maxilla (to or almost to hind border of pre-operculum); also, no species of Anchoa has more than 30 lower gillrakers.

Western South Atlantic (from a little north of Rio do Janeiro at 22°S to San Jorge Gulf, Argentina, at about 47° S).

Reported to reach 22 cm total length, i.e., about 17 cm standard length.

Marine pelagic,coastal and to about 800 km or more from the shore;forming dense schools atabout 30 to 90 depth in summer off Argentina, but down to 100 to 200 m depth in winter (Bellisio, López & Torno, 1979:56).Feeds as juveniles on zooplankton (copepods, their eggs and larvae especially calanoids), but with phytoplankton becoming increasingly important. Spawns throughout year most intensely and close to shore in October/November and again but more offshore and less intensely in May/June (distinct spring and autumn spawners proposed by Fuster de Plaza, 1964; situation perhaps more complex according to Ciechomski, 1967a). Schools around southern Uruguay and northern Argentina move offshore toward the end of the year and northward in March to June, moving south again and close to shore in August to October.

Mainly exploited seasonally by small Argentinian fishing boats over the shelf, chiefly during the migration period September to October. The total reported catch for 1982 was 10 137 t, but according to Bellisio, López & Torno (1979:57) the annual sustainable catch could be increased to between 786 000 and 1 180 000 t. The most important gear are: purse seines, beach seines, lampara, ring nets, trap nets, gillnets. Some consumed fresh, the rest canned.The total catch reported for this species to FAO for 1999 was 18 912 t. The countries with the largest catches were Argentina (9 832 t) and Uruguay (3 193 t).

Snout prominent, pointed, about 3/4 eye diameter; maxilla moderate, tip bluntly tapering or a little rounded, reaching to front margin of pre-operculum, extending a little beyond tip of second supra-maxilla; teeth in jaws numerous, small. Lower gill rakers long and slender; no gill rakers on hind face of third epibranchial; pseudobranch long, reaching onto inner face of operculum (Ref.189). Blackish blue dorsally, silvery white laterally and ventrally. All fins transparent (Ref. 27363).

Oceanodromous. Migrating within oceans typically between spawning and different feeding areas, as tunas do. Migrations should be cyclical and predictable and cover more than 100 km.

Dorsal spines (total): 0; Dorsal soft rays (total): 15 - 16; Analspines: 0; Analsoft rays: 17 - 21

Occurs in coastal waters to about 800 km or more from the shore; forming dense schools at about 30 to 90 m depth in summer off Argentina, but down to 100 to 200 m depth in winter. Schools around southern Uruguay and northern Argentina; moves offshore toward the end of the year and northward in March to June, moving south again and close to shore in August to October. Employs both filter- and particulate-feeding modes on zooplankton (Ref. 42392). In south Brazil, it is during winter when the most favorable season for larval feeding with high probability of prey consumption due to shelfbreak upwelling, high vertical stability in the water column and high production in the coastal region (Ref. 53892).

Occurs in coastal waters to about 800 km or more from the shore, forming dense schools at about 30 to 90 m depth in summer, but down to 100 to 200 m during winter. Feeds as juveniles on zooplankton, but with phytoplankton becoming increasingly important. Spawns throughout the year, most intensely and close to shore in October or November and again in May or June but less intensely and more offshore. Exhibits north-south and near shore-offshore migrations. During winter as the most favorable feeding period for larvae which occurs in the continental shelf in the extreme south of Brazil (Ref. 53892). Consumed fresh or canned (Ref. 4931).Typical size 7-13 cm SL (Ref. 47377).
