Abstract

Indian major carps are the widely consumed fish species of Pakistan, being a cheap source of proteins and unsaturated fatty acids, they are good for cardiovascular health. Water pollution due to discharge of untreated industrial waste water into water bodies contaminates this precious source of nutrients. The present study therefore, was aimed to assess deterioration of fatty acid profile of three Indian major carp species due to different concentrations of industrial wastes. The water samples were collected from the river Chenab at the site where it receives industrial wastewater via Chakbandi drain. After exposure to 1.5%, 3.0%, and 4.5% dilutions of collected water in different aquaria it was observed that proportion of unsaturated fatty acids in selected fish species were decreased significantly as the intensity of the dose increased (P < 0.05). Conversely the level of saturated fatty acids increased with the increasing dose of treatment (P < 0.05). These findings suggest that untreated wastewater not only deteriorate the fatty acid profile of aquatic animals but also these toxic substances can reach human body through fish meat and pose further health hazards. Therefore, it is highly recommended that industrial effluents should be treated before they are dumped into water bodies.

Highlights

Labeo rohita (Ham.), Catla catla (Ham.), and Cirrhinus mrigala (Ham.) having great economic importance are the commercial fish species and important aquatic food item of Pakistan due to consumer prefer ability owing to their taste and quality of meat (Hussain et al, 2018)
Concentration of unsaturated fatty acids decrease gradually as we increase the concentration of textile effluents for shop maximum value of unsaturated fatty acids present in T1 and gradually declined as we increase the effluent concentration in T2 an T3 similar observations were seen for polyunsaturated fatty acids like Omega 3 and Omega 6 fatty acids
The findings of present suggests that the values of PUFA decreased while that of SFA were increased in samples as compared to controls (Table 2-4)

Summary

Introduction

Labeo rohita (Ham.), Catla catla (Ham.), and Cirrhinus mrigala (Ham.) having great economic importance are the commercial fish species and important aquatic food item of Pakistan due to consumer prefer ability owing to their taste and quality of meat (Hussain et al, 2018). Big concentration of many pollutants may rise pH, total dissolved solids (TDS), biological oxygen demand (BOD), total suspended solids (TSS), electrical conductivity (EC), metals like as Cr, Cd, Ni and fecal coliform, Pb making such water toxic for irrigation and domestic use (Tariq et al, 2020). This untreated water has proved to be detrimental for human consumption. The aim of present study was to assess perturbed fatty acid profiles in Indian major carps after treatment with different concentrations of industrial effluents as a potential bio-indicator of water pollution
