Effects of smoking on fatty acids composition of croaker (<i>Pseudotolithus senegalensis</i>)

Fatty Acids Composition of Two Commonly Consumed Freshwater Fishes (Clarias gariepinus and Chrysichthyes nigrodigitatus) from the Cross River at Ahaha, Obubra, Nigeria

“…Fish oils are rich in highly saturated and unsaturated long chain fatty acids which plays vital roles in animal and human nutrition reflecting their characters in various critical biological processes. The fatty acid composition of these fish species decrease in the order saturated, > monounsaturated > and polyunsaturated fatty acids which was in agreement with available information on fatty acid composition of similar fish species as reported in previous work [42,25,22,20,3]. The most abundant of the SFAs were palmitic and stearic acids for the both species.…”

“…Polyunsaturated fatty acids are known as important chemical constituents for the human diet which can provide several health benefits. The lower values of PUFA than MUFA and SFA obtained in these species corroborates the findings of many researchers [37] The number of omega -3 (seven) and omega -6 (three) fatty acids recorder in this study were higher than those reported for two Loach species [21], some economically important fish species in Lagos [20] and croacker purchase from Lekki beach in Lagos [42]. Guler et al [56] [59].…”

“…The higher value of MUFA, 31.35% in African catfish than 30.36% in silver catfish although not significant (p > 0.05) agrees with various researchers who recorded differences in the composition of MUFAs in various fish species [53] [37] [20]. These values were similar to the 31.50% and 30.70% reported C. gariepinus and T. zillii respectively by Osibona [20] but were however higher than those reported for Pseudotolithus senegalensis (26.61%) by [42] and Pseudotolithus typus (24.90%) by Osibona [20]. Monounsaturated fatty acids and SFAs can be synthesized de novo.…”

“…Palmitic and myristic acids have been reported as the predominant SFA in freshwater channel catfish, Oncorhynchus mykiss, [43], while Kaliyamurthi et al [21] reported the abundant of palmitic, myristic and stearic acids in two loach species (Biota lohachata and B. geto) of Brahmaputra river, India. Similar results were obtained for African fishes as Ugoala et al [37], Mohamed and Al-Shabali [36], Osibona et al [22] and Salaudeen et al [42] reported palmitic, myristic and stearic acids as the most abundant SFAs in fishes.…”

“…Ackman [46] reported that high levels of palmitic acids is a characteristic of freshwater fish hence corroborates the findings in this study. The total of 43.18 and 42.24% of SFA recorded for African catfish and silver catfish respectively in this study were higher than those reported for fresh (35.79%), smoked with skin (39.62%) and smoked without skin (38.43%) croaker, Pseudotolithus senegalensis [42]. This study showed that C. gariepinus had a higher composition of saturated fatty acids than C. nigrodigitatus.…”
