United States (contiguous states) country information

Common names: Mobile chub
Occurrence: native
Salinity: freshwater
Abundance: | Ref:
Importance: | Ref:
Aquaculture: | Ref:
Regulations: | Ref:
Uses: no uses
Comments: Known only from larger rivers of Mobile Bay basin in Alabama and Mississippi (Alabama, Cahaba, Coosa and Tallapoosa), where confined below Fall Line. The construction of the Tenn-Tom waterway, which has altered the original free-flowing Tombigbee River into a series of standing pools has posed threat by eliminating this species from a major porton of its original geograpic range. A close monitoring of this species throughout the remaining parts of its range is suggested (Ref. 116539).

生物學特性     字彙 (例如 epibenthic)

Occurs in larger, moderately clear to turbid rivers and the lowermost parts of their major tributaries below the Fall Line in the Mobile Bay basin. These areas have moderate to strong water current and bottom comprising of a combination of gravel, sand and silt. Inhabits sympatrically with Macrhybopsis etnieri (with no evidence of hybridization) over a 40-km section of middle Cahaba River in Fall Line area of Alabama (Ref. 116539).

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00232 - 0.01084), b=3.13 (2.94 - 3.32), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
