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.

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.

The Vibrio is the most common genera with crustaceans often causing various diseases in Aquaculture and significant economic losses. Many Vibrio species are pathogenic to human and have been implicated in food borne diseases. The present study was carried out, the isolation and identification of pathogenic bacterial flora were isolated from infected in hepatopancreas of vannamei. The SPDS Oceanic farm, RS Aqua farm of and Valli vilas Aqua farm Vellar estuary, Cuddalore District, Tamil Nadu, during the period of (September 2013 to November 2013). The collected samples were plated on TCBS- (Thiosulfate-Citrate-Bile salt-Sucrose) agar medium. The present study, totally 253 green colonies were isolated from TCBS agar plates and among these, 175colonies were identified by using the biochemical tests showed the V. parahaemolyticus, V. mimicus, V. vulnificus, V. damsela and P. shigelloides. The maximum species was recorded in V. parahaemolyticus (83.4 %) and minimum was observed in V. mimicus (1.7 %).

The Meretrix casta is an edible clam for human beings and it is widely distributed around the aquatic ecosystem. The clam has relatively thick shells that can attain a length of three inches. The knowledge of the biology, culture and biochemical composition of any edible organism is extremely important. Though the size, shape and colour of clam are different their nutritive value is very good. A maximum average length of 27.15mm was observed in the M.casta studied during 2011 and a maximum average length of 26.51mm was observed during 2012. The average lengths of M.casta in all the three different estuaries studied were as follows: 27.15 > 25.82 > 25.04 mm in 2011 and 26.51 > 25.88 > 25.17mm in 2012. A maximum average weight of 7.824 and 7.155g was observed during 2011 and in 2012; a maximum weight of 7.528g and minimum of 6.941g was recorded uniformly in all the three different estuaries. However, in 2011and 2012 a maximum and minimum of average length of 26.86, 25.10 mm, and average weight of 7.67 and 7.05g respectively were noticed in both Vellar and Uppanar estuaries of M.casta. the present investigation, it is clearly observed that M.casta can grow a weight of 0.13g/day and length of 0.122mm/day among the three different estuaries studied in the Cuddalore district which is located in Bay of Bengal.

Seafood is an excellent provider of protein with high biological values. Fish, shellfish and other aquatic organisms are appropriate for food and have world-wide importance. They‟re wonderful sources of high quality proteins, superior to those in red meat and poultry foods. The human dietary amendments that characterize the “nutrition transition” include every quantitative and qualitative change in the human diets. The present study Meretrix casta meat is used for the preparation of excellent recipes like cake, soup and mint stuffed tomato with yellow clam using M. casta meat, that have the potential to be become a regular food item in the house hold diet with consumer acceptance. The differences in food habits over the length and breadth of the nation are most that available food resources are not being used properly due to the lack of information regarding their importance. The panel of judges vouched safe for taste and delicacy of the dishes in the present study. The panel detected that the dishes were a lot of as good as those created out of the much sought after seafood in taste, smell and flavor
