Length-Weight Relationship of 20 Cryptobenthic Fish in Coral and Rocky Reefs in the Gulf of California, Mexico

Figure 3

Comparison of LWR based on fresh (green) and in-formalin (purple) specimens. (a) Comparison of parameters a and b. (b) Effect of LWR difference on weight and biomass estimations. For example, the estimated weight of Acanthemblemaria crockery along the full simulated range size of the species is shown according to the two conservation methods. The biomass per quadrant of fish assemblages considering the 14 species in common between the present study (fresh specimens) and the anterior study (in-formalin specimens, [15] is also shown. Data are represented by site and reef types are indicated (coral and rocky). Three biomass values are shown: (i) the estimated biomass based on LWR parameters using in-formalin specimen (purple); (ii) the estimated biomass based on LWR parameters using fresh specimen (green); and the true (weighted) biomass (grey).
