KARACHI: Uncontrolled fishing fleets, high bycatch and large-scale post-harvest losses are putting Pakistan’s Arabian Sea biodiversity at growing risk, WWF-Pakistan warned on Thursday ahead of World Fisheries Day, calling for urgent reforms to protect coastal ecosystems and the livelihoods that depend on them. World Fisheries Day, observed globally on Nov. 21, highlights the mounting pressures facing marine environments, including declining stocks, habitat damage, pollution and climate-driven changes.
