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):

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

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!

Cheers,

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

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:
