Biologia     Glossario (es. epibenthic)

Obligate air-breathing (Ref. 126274); Found in ponds, swamps, brackish water (Ref. 6028), ditches and beels (Ref. 1479). Adults prefer stagnant waters in muddy streams (Ref. 4833). Feed on worms, insects and small fish (Ref. 6028). Accept chopped fish and shrimp in the aquarium. Breed throughout the year. Mitochondrial hypertrophy, noted in the double cone of the retina of this species, is considered a basic process in oil droplet formation (Ref. 10557) believed to be an adaptation for enhanced visual contrast detection in turbid waters (Ref. 10407). Used as live bait for angling larger snakeheads.

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

Spawning usually takes place at night in shallow water with a silty substrate. Eggs are laid in nests through elaborate tunnels in vegetated areas which look like vertical columns of water with the eggs floating in the center (Ref. 205). The male and female move towards the center of the nest during spawning where the male entwines his body to the female moving upward while releasing the eggs to be fertilised (Ref. 45309). Eggs are guarded by one or both parents. Hatching takes place in a day (Ref. 6028).

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=0.01023 (0.00801 - 0.01307), b=2.98 (2.92 - 3.04), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.70 se; based on food items.
Generation time: 1.2 (0.9 - 2.4) years. Estimated as median ln(3)/K based on 11 growth studies.
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (K=0.2; Fec=2,300).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (18 of 100).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 144 [56, 374] mg/100g; Iron = 1.07 [0.71, 1.61] mg/100g; Protein = 17.5 [16.6, 18.4] %; Omega3 = 0.138 [0.069, 0.274] g/100g; Selenium = 29.4 [12.4, 70.3] μg/100g; VitaminA = 55.9 [26.3, 115.7] μg/100g; Zinc = 1.27 [0.86, 1.81] mg/100g (wet weight); based on nutrient studies.
