Proximate, fatty acid and mineral composition of orange-spotted grouper Epinephelus coioides from Parangipettai coast

The marine fish are extraordinarily nourishing food and are affluently accessible fish meat source. Fresh examined sample of grouper fish was collected from Mudasal odai fish landing center. The protein, carbohydrate, lipid, ash and moisture contents of Epinephelus coioides were found to be 19.07 mg, 4.03, 2.61, 77.38 mg and 1.21 mg/g respectively. The potassium and phosphorus are the predominant elements other nine components are present in considerable quantities in the total of 11 minerals. Palmitic acid, Oleic acid and Stearic acid were observed to be the major elements of total presented 15 fatty acids. In this current study we have concluded the grouper fish having rich source of protein and good fatty acids and it will facilitate to enhance the nutrition level on poor folks

Proximate composition and Fatty acid analysis of Puffer fish, Lagocephalus inermis (Temminck and Schlegel, 1850) and Lagocephalus lunaris (Bloch and Schneider, 1801) from Parangipettai, Southeast coast of India

ABSTRACT The nutritional effects of marine food have increased far and wide due to the beneficial effects of consuming marine food, fats and oils. In general, the proximate composition is well known as a proportion composition of basic elements such as protein, lipids, carbohydrate, minerals and water. The puffer fish Lagocephalus lunaris and Lagocephalus inermis were collected at Mudasal odai fish landing centre and the skin and visceral organs like gonads and intestines were removed the edible portion only took for the analysis. Species of the fish sample was oven-dried in an electric oven at between 70 -80 °C until the samples had constant weight. The protein, carbohydrate, fat, ash and moisture content of green -rough-back puffer fish and smooth-backed blow fish were investigated. L. lunaris and L. inermis were has 9.22 %, 8.92 %, 1.96 %, 1.87 %, 11.25 %, 11.98 %, 80.32 %, 86.05 %, 0.96 %, 1.27 % respectively. Totally seven saturated fatty acids; ten Mono unsaturated fatty acids and two poly unsaturated fatty acids were found as the major components on the investigated puffer fish. Polyunsaturated fatty acid like n-3 has 31.17 %, 31.19 and n-6 7.26 %, 7.29 % of PUSFA found as the dominant composition on puffer fish. This study revealed that these species are having high saturated fatty acid and protein content and able to compete with more commercially utilize species in terms of nutritional value, and they can definitely also compete when it comes to taste. It can act as a good source of nutritional and economic value when it is carefully handled and properly cooked
