Short description
Morfologia | Morfometria
Raggi dorsali molli (totale): 13-15; Raggi anali molli: 13 - 16; Vertebre: 42. Anchoviella sanfranciscana is diagnosed from its congeners by the following characteristics: wide silver lateral band present, with a well-defined dark brown and yellow lateral band above - its total width is 1.5 to 2 times wider than the ocular diameter, (vs. width is less than 1 time in other congeners); distance from tip of dorsal fin to start of anal fin is similar in size as the dorsal fin (vs. distance is smaller in other congeners, except A. perfasciata); and 29-35 gill rakers in lower branch of the first branchial arch (vs. maximum is 27 in other congeners, except for A. cayennensis) (Ref. 116921).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00259 - 0.01222), b=3.18 (3.00 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
