Article impact statement: : Modeling and mapping human impacts can reveal conservation status and threat patterns for data‐poor marine species. Abstract Understanding the threats acting upon marine organisms and their conservation status is vital but challenging given a paucity of data. Here we provide a global‐scale study of cumulative human impact (CHI) and conservation status of … Read more Using cumulative-human-impact models to reveal global threat patterns for seahorses
Threats to Seahorses
Seahorse numbers have declined primarily because of egregious non-selective fishing, as well as intense targeted fishing.
They are heavily traded but generally it is non-selective fishing – and not demand for seahorses per se – that drives depletion. Many populations, particularly those in estuaries, are also suffering from habitat loss and degradation (e.g. destruction, sedimentation, eutrophication, pollution) as well as invasive species and climate change. However, fisheries are definitely the biggest pressure on seahorses as a genus, as on other marine life.
