Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 13 - 14; Anal soft rays: 13 - 14.

Found in shallow ponds and marshes of plains, and adjacent irrigation canals (Ref. 41299).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Female lays eggs inside mussels where they are fertilized by the male. Young remain in the bivalve until they can swim (Ref. 43281).

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=0.01148 (0.00705 - 0.01869), b=3.11 (2.97 - 3.25), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.5 ±0.2 se; based on size and trophs of closest relatives

Generation time: 1.3 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.82-2.15; Fec assumed < 100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (16 of 100).

Price category (Ref. 80766): Unknown.

Rhodeus ocellatus (Kner, 1866)
