The populations of two species of seahorses are declining. and are among the internationally more commonly traded species of seahorse. They are particularly used for Chinese medicine and aquarium trade. Apart from being harvested, these species are also caught as by-catch when fishing for other species. Destruction of the species’ main habitats (coral reefs, seagrass beds and mangrove forests) threatens both species. Currently, both H barbouri’s and H. comes’ statuses on the IUCN’s Red List of Threatened Species are “vulnerable”.
You are part of a team of specialists whose mission is to determine the best way to preserve two species of seahorses: and . Your team has been invited to make a presentation at an international conference where other teams will be competing for project funding. Will your presentation earn your project funding?
Your task is to:
1. Find out what has caused the decline in the seahorse population in the Philippines.
2. Investigate methods for reversing the population trend.
3. Present a proposal that will increase and sustain seahorse populations so that they do not become extinct.
Your presentation must include graphics and visual organizers. Presentations may be in the form of PowerPoint or overhead projector transparencies.
