生態學
; 海洋; 海洋洄游的; 深度上下限 3 - 80 m. 13°C - 23°C (Ref. 6), preferred 16°C (Ref. 107945); 5°S - 43°S, 82°W - 69°W (Ref. 54434)
Southeast Pacific: Aguja Point, Peru to Chiloé, Chile (distribution dependent on the coastal extent of the Peru Current).
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 12.0, range 10 - 12.5 cm
Max length : 20.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 189); common length : 14.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5504); 最大年齡: 3 年 (Ref. 189)
背棘 (總數): 0; 臀棘 0. Body elongate, slender, and rounded in cross section; snout long and prominent; lower branch of first gill arch with 34 to 49 gill rakers; anal fin with fewer than 22 rays, located behind dorsal fin base; body shiny blue or green (Ref. 55763). There is a silver stripe along flank in juveniles which disappears with age. The high number of gill rakers distinguishes it from all Pacific species of Anchoa.
Adults occur mainly within 80 km of coast, forming huge schools, chiefly in surface waters. Are filter-feeders entirely dependent on the rich plankton of the Peruvian Current. In some studies, diatoms constituted as much as 98% of the diet. Large populations of guano birds and pelicans also depend on this fish (Ref. 9988). Utilized as fish meal and oil (Ref. 9988).
