We present the length-weight relationships (LWRs) in 20 cryptobenthic reef 5sh species in the Gulf of California (Mexico). Nineof these species had no LWR records yet. However, the other species had LWRs based on in-formalin specimens collected morethan 20 years ago. -is conservation method has likely a7ected LWRs parameters. Our study showed higher estimations of theparameter a obtained on fresh specimens than in-formalin individuals. On the other hand, parameter b was not a7ected.-erefore, the biomass estimates using previous LWRs were strongly underestimated. Ergo, the similitude in parameter b betweenthe 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 thatthe body 5tness was not a7ected by reefs type, which means that both habitats seem to o7er similar living conditions for sharedspecies.
