Abstract

Length-weight (LWR), length-length (LLR) relationships and relative condition factor (Kn) were determined for the conchfish Astrapogon stellatus (Cope, 1867) in the Mesoamerican Reef System, Mexico. A total of 26 specimens were collected between 2016 and 2018. The LWR for A. stellatus was W = 0.0159*TL2.972. LLR was highly significant (r2 = 0.989) and the range of Kn was 0.85–1.26. These findings have not been previously reported in the literature, such data is valuable for understanding population dynamics for this a poorly known species that could be within some endangered category.
