Marine conservation

The first recorded sighting of a sperm whale off the Sindh coast, approximately 40 nautical miles southwest of Karachi, is a reminder of this ecological richness.

The 45-foot mammal, documented during an expedition by a WWF-Pakistan board member, adds to evidence of the Arabian Sea's importance as a habitat for some of the world's largest marine species.With 26 species of whales and dolphins already documented in Pakistani waters, the discovery should encourage greater scientific interest in marine ecosystems that have received far too little attention from the authorities.

Protecting these mammals is closely connected to preserving the ecological processes on which marine life depends.

Yet these delicate systems face mounting pressure from overfishing, plastic waste, industrial pollution, shipping activity and rising sea temperatures.

Entanglement in fishing nets and collisions with vessels pose particular dangers to whales and dolphins.

The degradation of marine habitats also threatens fish populations and, consequently, the livelihoods of coastal communities dependent on them.Pakistan has demonstrated that conservation measures can produce results.

WWF-Pakistan's efforts to introduce subsurface gillnets in tuna fisheries substantially reduced the accidental capture of marine mammals, showing that environmental protection need not come at the expense of fishing livelihoods.

Similarly, the designation of Astola and Churna islands as marine protected areas represents progress towards safeguarding important habitats.

However, protected status must be accompanied by restrictions on environmentally damaging activities and regular ecological monitoring.

The federal and provincial governments must invest in marine research and identify sensitive habitats or migration routes for better protection.

Marine conservation cannot remain confined to a handful of coastal locations when offshore ecosystems also require protection.
