生态学
海洋; 海洋洄游的; 深度上下限 3 - 80 m. 亞熱帶的; 13°C - 23°C (Ref. 6); 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).
東南太平洋: Aguja Point, 祕魯到智利的智羅島.(分布取決於祕魯水流的海岸範圍)
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 12.0, range 10 - 12.5 cm
Max length : 20.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 189); common length : 14.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5504); 最大年龄: 3.00 年 (Ref. 189)
背棘 (总数): 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.
细长的身体, 细长的, 而且圆的横切面; 吻长而突出的; 低分支第一个鳃弓有 34 到 49个鳃耙; 臀鳍有少于 22个鳍条, 位于背鳍基底后面了; 身体有光泽的蓝色或绿色.(参考文献 55763) 一条银色的斑纹在随着年龄而消失的稚鱼中沿着侧面有。 鳃耙的高数字区别它和 Anchoa 的所有太平洋种。
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).
主要地生存在海岸 80 公里之内,形成极大的鱼群, 主要地在水表面中。 一个滤食动物完全地取决于秘鲁水流的丰饶浮游生物。 在一些研究中，硅藻构成了多达 98% 的食性。 粪鸟与鹈鹕的大族群也仰赖这一个鱼。 (参考文献 9988) 用来作鱼粉与油了。 (参考文献 9988)
