“…Overall, potassium was found to be the mineral with the highest concentration in all the fleshy tissues compared to other minerals analyzed. The mean potassium values obtained in this study are comparable to potassium values of 1276.4mg/kg and 2064.8mg/kg reported by Oksuz et al (2011) for gold band goatfish and stripped red mullet respectively. The potassium values obtained in this study are also comparable to the studies of Mohammed et al (2010) and Luczyiska et al (2009) who reported mean potassium concentrations ranges of 954-1210mg and 1429-2387mg in species of freshwater fish in Sudan and Poland respectively.…”

This study was undertaken to determine the proximate and mineral composition of Pelusios castaneus (West African-mud turtle) so as to contribute to the availability of data in Nigeria. A total of thirteen (13) male and female each of African mud turtle (Pelusios casteneus) were purchased in Benin City, Nigeria. Specimen were identified to species level, stunned and slaughtered; then each of the turtle were dissected into flanges and Microwave digestion system (Closed Vessels Acid Digestion – MARS System - CEM) procedure was used for the digestion of all the samples based on organic extraction technique before the proximate composition and the mineral contents of the flesh were determined using AOAC methods and standard technique. Data were analyzed using SPSS (version 21) and statistically using ANOVA and DMRT. Result shows that there were significant variations in the different parameters studied; the highest and lowest moisture content values of 67.00% and 52.56% were observed in the male and female respectively. Highest crude protein and lipid values of 26.78% and 15.00%, were observed in the female respectively; while the highest ash content value of 11.33% was observed in the male. While the mean mineral concentrations in the flesh varied among the different elements studied, the overall potassium had the highest value of 4030.82mg while the least value was observed in magnesium (871.04mg). Though Pelusios castaneus has been culturally important to Nigerians, the finding shows that the flesh is a valuable source of mineral elements and proximate components required in diet. Domestication in Nigeria is therefore encouraged to make them commercially available to reduce the pressure on their harvest from the wild thus preventing their going into extinction.

“…45 Taurine supplementation has been found to increase adiponectin levels, Table 4, eight minerals were quantied in S. zunasi Bleeker, including four macro minerals (Ca, K, Na, and Mg) and four trace minerals (Fe, Zn, Mn, and Cu). Ca (1240 AE 0.02 mg/100 g) was the major mineral in S. zunasi Bleeker, the content of which was found to be higher than that in Sardinella longiceps (523.9 AE 45.6 mg/100 g), 47 Mullus surmeletus (398.6 AE 105.9 mg kg À1 ) and Upeneus moluccensis (617.4 AE 90.5 mg kg À1 ), 48 followed by K (308 AE 0.08 mg/100 g), Na (168 AE 0.04 mg/100 g) and Mg (56.30 AE 2.7 mg/ 100 g). Ca rich in S. zunasi Bleeker suggests that it could be a good choice for nutritional supplements.…”

“…Ca rich in S. zunasi Bleeker suggests that it could be a good choice for nutritional supplements. The analysis of microelements revealed that S. zunasi Bleeker possessed Fe (9.48 AE 0.05 mg/100 g), Zn (2.55 AE 0.06 mg/100 g) and Mn (0.59 AE 0.01 mg/100 g), and the content of Cu was less than 0.5 mg/ 100 g. Fe is one of the essential trace minerals that good for health, the level of Fe (9.48 AE 0.05 mg/100 g) in S. zunasi Bleeker was much higher than that in Upeneus moluccensis (7.3 mg kg À1 ) and Mullus surmeletus (6.4 mg kg À1 ), 48 indicated S. zunasi Bleeker may be taken as a good supplement source of Fe with healthy benets to human. 49…”

“…Polat et al [32] reported that seasonal lipid level of red mullet was in the range of 3.68-5.76% using Bligh and Dyer method. The lipid contents of gold band goatfish and red mullet were found to be 4.35 AE 1.05 and 10.38 AE 1.9%, respectively, by Oksuz et al [33] with Bligh and Dyer method. Total lipid levels of red mullet were reported to be highly variable, with very low levels in spring (0.96-1.48%) and high levels in autumn (7.28-8.72%) by Di Lena et al [34] using Bligh and Dyer method.…”

The efficiency of the green extraction methods ultrasound‐assisted extraction (UAE) and microwave‐assisted extraction (MAE), and conventional methods (Soxhlet and Bligh and Dyer), on lipid content and fatty acid profiles of six fish species (Mullus barbatus, red mullet; Upeneus moluccensis, goldband goatfish; Mullus surmuletus, surmullet; Anguilla anguilla, European eel; Pagellus erythrinus, common pandora, and Saurida undosquamis, brushtooth lizardfish) are evaluated. The results of lipid content of fish species show that the Bligh and Dyer method and UAE in general are more efficient than other methods. There are statistical differences in the fatty acid composition of fish oil by four extraction methods (p < 0.05). Saturated (SFA), monounsaturated (MUFA), and polyunsaturated fatty acid (PUFA) contents of fish species range from 29.51 mg 100 g−1 fish (Soxhlet)–1400 mg 100 g−1 (UAE), 15.52 mg 100 g−1 (UAE)–2237.18 mg 100 g−1 (Bligh and Dyer), and 14.36% (Soxhlet)–646 mg 100 g−1 (Bligh and Dyer), respectively. Generally, Bligh and Dyer give the higher values in surmullet, red mullett, and common pandora in terms of SFA, MUFA, PUFA, and the dominant fatty acids (C16:0, C18:0, C16:1, C18:1n9, C18:1n7, C22:1n9, EPA, DHA), whereas MAE and UAE methods give better results in goldband goldfish and European eel, respectively. Thus, extraction methods affect the lipid yield and fatty acid profiles of extracted oil of different fish species. Practical Application: Total lipid content of seafood is an important parameter used in biochemical, physiological, and nutritional studies. Thus, reliable methods for the quantitative extraction of lipids from this type of food are of critical importance. The effects of green and conventional extraction methods on lipid yield and fatty acid profiles of fish species are compared in order to determine the most effective method for extracting lipid with high yield and high content of PUFA, especially EPA and DHA. The effects of green and conventional extraction methods on lipid yield and fatty acid profiles of fish species are evaluated. The extraction methods affect the lipid yield and fatty acid profiles of extracted oil of fish species. The Bligh and Dyer method and UAE in general are more efficient than other methods. In terms of SFA, MUFA, PUFA, EPA, and DHA; Bligh and Dyer gave the higher values in surmullet, redmullet, and common pandora whereas MAE and UAE methods gave better results in goldband goldfish and European eel, respectively.
