The proximate, chemical and amino acid composition of four oven dried shell fish meat samples were analysed, Clam, (<i>Mercenaria mercenaria</i>), Whelk, (<i>Thias coronata</i>), Oyster (<i>Crassostrea gasar</i>), and Periwinkle (<i>Tympanotonus fuscatus</i>). Results shows that whelk has the highest moisture content of 13.96±0.01, followed by oyster 8.99±0.00, clam, 8.98±0.01 and periwinkle 6.50±0.04. The protein content of periwinkle was the highest with a protein content of 70.42±0.03, followed by oyster 64.70±0.00, whelk 47.3±0.03, and clam 46.90±0.00 was the least. Ash content was highest in whelk 5.62±0.00, followed by clam 5.07±0.03, oyster 4.23±0.00 and the least periwinkle 3.38±0.01. The fat content of oyster was the highest with 10.60±0.00, followed by clam 10.07±0.03, whelk 9.20±0.00, and periwinkle 4.76±0.01, the least. Whelk contains the highest crude fiber content 10.45±0.01, followed by clam 10.10±0.00, oyster 5.33±0.04 and periwinkle 3.56±0.01. The calcium content was highest in oyster 580±0.000mg/100g sample and the least clam 101±0.000mg, selenium was highest in clam 40±0.000mg, and lowest in oyster 0.50±0.014mg. Oyster contains the highest levels of phosphorus 200±0.000mg, and the least whelk 110±0.000mg. Periwinkle contains the highest levels of Magnesium 150±0.000mg and the least clam 40±0.000mg. Oyster contains the highest levels of Zinc 100±0.000mg, the least clam 70±0.000mg. Clam contains the highest levels of iron 330±0.000mg and the least periwinkle 183.10±0.071mg. The highest level of Sodium was found in oyster 590±0.000mg and lowest clam 150±1.414mg. The mineral content of the four shell fish however differ significantly from each other at the (P<0.05). All the four shell fish contains all the essential and non-essential amino acids, they however differ significantly from each other at (P<0.05). The total amino acid values was highest in oyster with total amino acid values of 86.05±0.071, followed by whelk with total amino acid values of 83.02±0.000, clam with total amino acid values of 82.22±0.014 and the least is periwinkle with total amino acid values of 78.45±0.000. Oyster contains the highest total essential amino acid values 42.06±0.000, followed by whelk with total essential amino acid values of 40.65±0.014, clam 39.90±0.014 and the least is periwinkle with total essential amino acid values of 35.16±0.014.
