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.

Wheat is a common staple crop in Pakistan and it is also a major component of most people's daily diets. Pakistan is ranked eighth in the world for wheat production. The fifth major factor affecting crop yields is a lack of micronutrient availability. A field experiment was carried to determine the impact of foliar application of boron on the productivity of different varieties of wheat at Agronomic Research Farm, University of Agriculture, Faisalabad during Rabi season in 2020-21. The crop was sown by hand drill in plots with a net size of 6.5 m × 1.8 m. The experiment was comprised of 12 treatments in randomized complete block factorial design with two factors i.e. V1: Ghazi 2019, V2: Akbar 2019, V3: Anaj 2017, and four boron levels i.e. B0: 0g ha-1, B1: 50g ha-1, B2: 60g ha-1 and B3: 70g ha-1. The source of boron was boric acid which contains 5% B. Significantly the plant height (7.46%), productive tillers (6.01%), spike length (24.18%), number of spikelets per spike (35.53%), number of grains per spike (42.32%), 1000-grain weight (19.44%), grain yield (22.15%), biological yield (24.33%), harvest index (3.63%) increased as compared to control in wheat variety Akbar 2019 where 70 g ha-1 boron was applied at booting, flowering and milking stages. Recommended from observations that 70g ha-1 boron at the booting, flowering and milking stages is helpful for achieving a higher economic yield of wheat.

For their protection during the very adverse conditions produce different types of primary and the secondary metabolic compounds. As these stresses progressed in plants, a multi - gene response is triggered which caused changes in many of the proteins, signaling molecules, primary and secondary metabolites, amino acids and so on. The metabolism in plants is disrupted which leads to metabolic enzymes inhibition, substrates shortage, an increased demand of some particular compounds or all these factors combination. In this review, we showcase various kind of abiotic stresses which harms the plant. We also describe how the time scale variable stresses impact profile of secondary metabolites which could be used to identify different stresses. This paper has ability to attract researchers’ attention operating on the quantitative trait locus mapping with metabolites and also metabolomics genome wide linkage.
