Levenscyclus en paargedrag
Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven
Observed presence of two distinct waves of developing oocytes in a study indicates a group-synchronous ovary in this species, thus, subsequent spawning during the same breeding season may occur though unverifiable in the same study (Ref. 57432).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5781 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00229 (0.00112 - 0.00470), b=3.19 (3.00 - 3.38), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.7 ±0.58 se; based on food items.
Generation time: 7.3 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Weerstandsvermogen (Ref.
