Etymology: Anchoa: Italian ancioa = anchovy (Ref. 45335).
Eponymy: Professor Dr Boyd Wallace Walker (1917–2001) was an American fisheries biologist; ultimately Professor Emeritus of Zoology-Fisheries at the University of California, Los Angeles, where he worked for over three decades (1949–1980). [...] (Ref. 128868), visit book page.
Environment: milieu / climate zone / depth range / distribution range
Ökologie
seewasser; süßwasser; brackwasser; tiefenbereich 0 - 50 m (Ref. 96339). Tropical; 31°N - 5°N, 115°W - 77°W (Ref. 189)
Eastern Central Pacific: Gulf of California at San Felipe, Baja California and along Sonora and Sinaloa coasts, Mexico, south to Panama, possibly reaching further south.
Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 14.5 cm TL Männchen/unbestimmt; (Ref. 96339)
Rückenflossenstacheln (insgesamt) : 0; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 23 - 32. Snout moderately pointed, about 3/4 eye diameter; maxilla long, tip sharply pointed, reaching to or just beyond gill opening, but shorter and more blunt at 4 to 5 cm standard length; gill cover canals of walkeri-type. Pectoral fins large, tip reaching to beyond pelvic fin base; anal fin origin below dorsal fin origin or a little behind. Silver stripe along flank, as eye in some places.
Presumably schooling and most often found in warm, murky waters near shore and in bays near river mouths (specimens taken some km up the Rio Santiago, Nayarit, Mexico). Capable of tolerating lower salinities than that of the sea (Ref. 9298). The ovarian eggs are elliptical. Caught as a by-catch of encircling, lamparo, and trawl nets (Ref. 9298).
