Impacts of Marine Waste, Ingestion of Microplastic in the Fish, Impact on Fishing Yield, M’diq, Morocco

Abstract

Marine pollution has always shown many impacts on the environment all around the world. In this study, two of the impacts of debris are evaluated on the northern coast of the Mediterranean Sea in Morocco. The evaluation of the ingestion phenomenon of micro plastic in the fish, demonstrated that 10% was the percentage of fish samples which ingested microplastic for both species with higher values for the benthic fish, Diplodus cervinus, for the pelagic fish, Auxis thazard. The other impact detected is the presence of marine litter; 86% is the percentage of occurrence of waste in the fishing nets, which means the accumulation of debris in the seabed. This growth of marine litter leads to increased risk for marine biology in general, and to the appearance of other negative effects; in particular the low economic yield of this maritime activity.
