The biofouling issue is a tenacious issue throughout the history of aquaculture farming in the world, however it has elevated in priority as labour and electricity costs have arisen in recent years. Besides, fouling development is frequently fast on the grounds that the waters encompassing aquaculture activities are enhanced by natural and inorganic squanders (uneaten food, fecal and excretory material) created by high-density fish populations. The large surface area and structure of mesh material, especially multifilament mesh, is exceptionally appropriate for colonization and development of fouling. Biofouling of fishcage netting is a critical operational issue to aquaculture. The occlusion of mesh and the subsequent limitation in water exchange adversely influences fish health by the reduction in dissolved oxygen (DO) and the accumulation of metabolic ammonia. Fouling is also reducing the cage floatation, cage deformation, increases structural fatigue, and may go about as a supply for pathogens. The effects of fouling differ significantly relying upon season and area, and are additionally impacted by cultivating techniques and practices. The impacts of these factors are reviewed and highlighted. Suggesting an effective biofouling control will help to develop non- toxic coating particularly suited for aquaculture applications in future.
