Marine aquatic life is one of the primary food sources for human beings and a drinking water source for the Gulf, Mediterranean, and other world countries. In this view, the author has undertaken studies on the distribution of seasonal dissolved heavy metal (Cd) in the coastal waters of Visakhapatnam over one year (February 2003 to January 2004) and to assess the hydrological and biological factors of carbohydrates and lipids in marine Crab (Portunus sanguinolentus (L)) affecting their concentration levels. The result has been followed respectively in this research study. The Cadmium (Cd) and lipid levels were noticed in the 11 selected experimental sites (PLW5 to PLW1 – MPS – PRW1 to PRW5 in the present study for all the samples collection. The author has noticed carbohydrates and lipid levels in the same survey. On the other hand, high depletion was found in postmonsoon at MPS at 5.208 mg/g and 30.128 mg/g at MPS over the all-experimental sites. The present study evaluated Cadmium (Cd), carbohydrates, and lipids in marine water and The Visakhapatnam coast in different seasons like pre-monsoon, monsoon, and postmonsoon. The Cadmium founded to be high at 0.0460 µg/ml and 0.1383 µg/g, respectively, in water and crab tissue at MPS in all three seasons among all sites, and another hand, the author was noticed carbohydrates and found lipids' high reduction percentage (RPC) in postmonsoon at MPS 50.21% and 16.42% at PRW3 in monsoon compare with overall sites in three seasons, due to toxic Cd could be accumulated in marine Crab through the food chain as well osmosis process of water and body flues of Crab. This bioaccumulation process could be a path for a human being through the food chain. Cadmium accumulates its lead toxic effect with systemic effect on human body organs especially cause kidney damage (renal tubular damage). Human and animal studies indicate skeletal damage (osteoporosis). Key words: Cadmium, Crab, Carbohydrates, Lipids, Water
