Allard, L., Toussaint, A., Vigouroux, R., & Brosse, S. 2015. Length-weight relationships of 58 fish species in French Guiana streams. J. Appl. Ichthyol., 31, 567–570. dx.doi.org/10.1111/jai.12712.

ABSTRACT
Length-weight relationship parameters of the form W=aL^b are presented for 58 fish species representing 36 genus and 19 families captured in streams of French Guiana. LWRs for 53 of the species are estimated for the first time.

There are a few new max SL reported in here. Perhaps our only area for concern? The authors report that they recorded SL in mm, but their SL numbers are very small. Therefore either their data is presented cm... or these fish are REALLY short. If it's simply reported as cm, here are new SL values (which I've expressed as real mm below):

• Helogenes marmoratus
  79mm
• Hypostomus gymnorhynchus
  266mm
• Pimelodella geryi
  108mm
• Pimelodella procera
  117mm

Jools, if you're okay with these, I'll add them in to their respective CLOGs.

Cheers, Eric

Yes, where these figures are > the existing CLOG data then (because it's verified, published data) the site should be updated and I would appreciate that!

Okay, will do.

Here's a similar paper:

Cella-Ribeiro, A., Hauser, M., Nogueira, L. D., Doria, C. R. C. and Torrente-Vilara, G. 2015. Length–weight relationships of fish from Madeira River, Brazilian Amazon, before the construction of hydropower plants. J. Appl. Ichthyol., 31, 939–945. dx.doi.org/10.1111/jai.12819

ABSTRACT
Length–weight relationships (LWRs) are presented for 112 freshwater fish species representing 23 families and five orders captured in the Madeira River, the largest white-water river tributary of the Amazon River. The allometry coefficient (b) of the LWR (Wt = aSL^b) ranged from 2.446 to 3.856 with a median value of 3.102. Eight new LWR records are presented for Amazonian species as information for FishBase. LWRs in the present study provide historical data on a and b coefficients prior to the damming of the Madeira River in November 2011, allowing comparison estimates of predicted future population parameters as influenced by human intervention.

I've already searched it for any new SL records and made changes to the corresponding CLOGs:

• Ageneiosus ucayalensis
  325mm
• Auchenipterichthys thoracatus
  138mm
• Centromochlus heckelii
  139mm
• Trachelyopterus galeatus
  237mm
• Hemidoras stenopeltis
  194mm
• Nemadoras humeralis
  135mm
• Opsodoras boulengeri
  193mm
• Trachydoras paraguayensis
  138mm
• Hypophthalmus edentatus
  390mm
• Hypophthalmus marginatus
  470mm
• Sorubim elongatus
  322mm
• Sorubim maniradii
  256mm
