There is an effort to conserve the Mobulid (manta and devil rays) species (9-11 species) as most of the species are considered endangered. Purse seine nets and gill nets are the leading reason for the death of mobulids. But there is a new fishing gear hack that gives mobulids a better chance for survival if they are caught in purse seine nets. The device is called a manta grid and it could be used as a tool in the conservation tool belt for tuna fishing (or any other type of fishing) in the future. Other tools could consider pre-fishing adjustments that could give mobulid species a fighting chance at survival. We are going to discuss these tools and strategies in this episode.

A graduate student and the Executive Director of Manta Trust, Joshua Stewart has discovered a nursery habitat in the Flower Garden Banks National Marine Sanctuary in the Northwestern Gulf of Mexico. This is a HUGE discovery as manta rays are known to migrate around the world making it difficult to find their important life history habitats.
Joshua is looking forward to conducting further research in the near future to find out the size of the nursery habitat and whether the boundaries will go beyond the Marine Sanctuary boundaries. If the boundaries are larger, then the Sanctuary managers have grounds to expand the boundaries and protect the Endangered Species.
