Resumen:
A study was carried out to assess the biological aspects of Dormitator
maculatus, analyzing sex ratio, diet, and growth estimates based on the
von Bertalanffy model. All organisms were captured with the help of 50
m. long cast fishing lines at ten sampling stations monitored between
May 2015 and May 2017. 642 subjects were captured ranging between 3 to
14.7 cm total length for males, 3.9 to 15.9 cm for females. Sex ratio is
1:1 female:male, they consume nine different types of food, mainly
Ruppio maritima, detritus, benthic algae and ostracods. The constants
for the von Bertalanffy model for frequency analysis were, a Maximum
Length (Maxi.) of 22.37 cm for males, 22.71 and 22.93 cm or females, k=
0.20785 and 0.17199 for males, 0.20856 and 0.16749 for females. For
scale analysis, the growth rate was MaxL =19.51, and k=0.26642. The
grown rate estimate (empty set') ranging from 1.93 to 2.03 with the
different adjustments. Currently, there is a reduction in population
that may endanger its exploitation, affecting other species that feed
from it, is recommended to increase the number of studies that aim at
predicting the possible environmental impacts on productive use systems
involving the ichthyofauna that inhabits the Alvarado lagoon.
