Abstract

Advances in fisheries system have been made in the few past years due to different technological progress in the food chain system by improving the mutual communication among different types of organisms. Overfishing, anthropogenic climate change, and pollution are already having measurable impacts on the marine environment throughout the majority of the globe, and their potential long-term repercussions are very concerning. Fishing activity contributes to marine debris; the proportional contribution of recreational fishing has not been quantified. New approaches that are being used in various ways include the precautionary approach, the ecological approach, adaptive management, and harvest control rules. Growth in coastal population has made water and land pollution worse and placed additional pressure on coastal development. Satellite remote sensing has been an essential tool in fishery research, management, and harvesting because it offers synoptic ocean measurements for evaluating environmental influences on the abundance and distribution of fish populations and allows ecological analyses at community and ecosystem scales. Synthetic super-active analogues with higher inducing potency at lower doses were developed using biotechnological techniques including protein engineering and recombinant DNA technology. There are many methods of preservation, including as drying, smoking, freezing, chilling, and brining. Fish that has been smoked or dried has more nutrients and is easier to digest. Fish is often prepared by smoking or drying; both processes eliminate moisture by heating, which reduces the development of germs and increases shelf life. Advances in genetic engineering also helpful for improving the new varieties in the fisheries system.
