Biologie     Verklarende woordenlijst (b.v. epibenthic)

Feeds mainly during the daytime, though some large fish (15-20 cm SL) extend their foraging activity to dusk (about 1800-1900H). Night is spent sheltered among vegetation. Small-sized to medium-sized fish (7-10 cm) are solitary and patrol feeding territories (3-4 square m.) in a way similar to that reported for the scale-eating Catoprion mento. Stalking with some use of plant cover is a frequent mode of hunting employed by S. marginatus. It approaches its prey with a slow, stealthy movement from behind or below. It strikes its prey on the tail or anal fin, of which a piece is clipped out with a jerking motion of the body. This clipping is audible underwater. Lurking is also employed during daytime (Ref. 9080).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01318 (0.01056 - 0.01645), b=3.16 (3.11 - 3.21), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.56 se; based on food items.
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
