Abstract
We present the length-weight relationships (LWRs) in 20 cryptobenthic reef fsh species in the Gulf of California (Mexico). Nine
of these species had no LWR records yet. However, the other species had LWRs based on in-formalin specimens collected more
than 20 years ago. Tis conservation method has likely afected LWRs parameters. Our study showed higher estimations of the
parameter a obtained on fresh specimens than in-formalin individuals. On the other hand, parameter b was not afected.
Terefore, the biomass estimates using previous LWRs were strongly underestimated. Ergo, the similitude in parameter b between
the two conservation methods highlights that the shape of the LWRs is conserved and did not change over the last 20 years. Finally,
we compared the LWRs of shared species in the region’s two main types of shallow reefs, i.e., coral and rocky reefs. We found that
the body ftness was not afected by reefs type, which means that both habitats seem to ofer similar living conditions for shared
species.
