IS THE DEVIL FISH (HYPOSTOMUS PLECOSTOMUS), THAT HABITS IN THE ECOSYSTEM OF PLAN DE AYALA, OSTUACÁN, CHIAPAS COMESTIBLE ?

Abstract

Objective: To evaluate the exploitation of Devil fish (Hypostomus plecostomus), analyzing the content of heavy metals, as well as its ecosystem.
Design/methodology/approximation: To address the study two zones were selected; three random samples were taken with three replications in each zone, analyzing the physicochemical parameters of water in situ and ex situ, for heavy metals and chemical demand of oxygen. Devil fish samples were collected to analyze their content of heavy metals, in gills, muscle and liver, using the optical emission spectrophotometer with inductively coupled plasma (ICP-OES). The results were the average of the determinations in each case and, a proximal chemical analysis on the Devil fish meat was also carried out.
Results: The water quality of the Grijalva River that crosses the town of Plan de Ayala, Ostuacan, complied with the maximum permissible limits of the applicable regulations to water bodies of national goods. The content of heavy metals in the organs of Devil fish fulfilled the maximum permissible limits of national and international regulations, making its consumption viable regarding this parameter.
Limitations of the study/implications: This study is a general diagnosis, and therefore it is necessary to study the use more thoroughly, to raise confidence.
Findings/Conclusions: Due to its high protein content, Devil fish can be an alternative for balanced feeding of other aquatic species in captivity.
