INTRODUCTION
The research capitalizes on the condition of coastal marine environment due to eutrophication (Gray, Shiu-sun Wu and Or). This process of enrichment that is suppose to foster growth to marine and aquatic life is believed to have an adverse effect due to the disturbance that it creates in the marine system. According to the authors, eutrophication facilitates for excessive nutrient absorption of most aquatic plants and microorganism. As a result, it increases the rate of sedimentation that results to hypoxia. When this happens, fishes and other marine life forms do not receive sufficient oxygen. Malabsorption of oxygen stags growth. This happens when the oxygen concentrations in the ocean is between 6.0 to 4.5mg O2 l-1. In addition, their metabolism is also affected when concentration reaches 4.0 and 2.5mg O2 l-1. Finally, beyond oxygen concentration of 2.0 to 0.5mg O2 l-1 the fishes could die.
METHODS
RESULT
The study revealed that the enrichment of the coastal marine environment facilitates for excessive nutrient absorption of the marine life resulting to overproduction of phytoplankton that could compromise oxygen concentration. If there is over production of phytoplankton, many marine lives like fishes and marine fauna will perish thereby creating an imbalance in the marine ecosystem.
DISCUSSION
The proponents believe that to avert the effects of hypoxia by fostering a full scale assessment of the marine environment. Full scale assessment is necessary to know the oxygen concentration in the marine ecosystem and assess whether it is at an alarming level. The early detection of eutrophication is necessary as to apply the saying that prevention is better than cure.
