Biology     Glossary (e.g. epibenthic)

Favors the shallow mud bottom waters near fringing vegetation such as papyrus and Vossia. Feeds mainly on Caridina and caenid larvae (Ref. 9606). Oviparous (Ref. 205). A male to female ratio of 1:10.5 has been noted for this species (Ref. 10608). Migrates up the river to spawn (Ref. 10608).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00712 - 0.03073), b=2.87 (2.69 - 3.05), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.50 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 206).
Vulnerability (Ref. 59153):  Low vulnerability (12 of 100) .
Price category (Ref. 80766):   Unknown.
