Length-weight (
LWR
), length-length (
LLR
) relationships and relative condition factor (
K
n
)
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*
TL
2.972
. LLR was highly significant (
r
2
= 0.989) and the range of
K
n
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.
