The Madagascar Pygmyskate (Fenestraja maceachrani) is a rare deepwater, medium-sized skate (known to at least 41.5 cm TL) known only from two specimens off the southwest coast of Madagascar in the western Indian Ocean. This species is believed to inhabit calcareous sandy mud areas of 600-765 m depth. Likely to be caught as bycatch by the deep-sea shrimp fishery occurring off the west coast of Madagascar, but bycatch data are not available. At present there is insufficient information to assess this species beyond Data Deficient. However, given its apparently restricted range in an area that is known to be fished, bycatch levels should be quantified and this species should be reassessed in the near term.

|Current Population Trend:||Unknown|
|Habitat and Ecology:||Bathydemersal deepwater species occurring between 600 and 765 m depth on calcareous sandy mud (Séret 1989). The largest known specimen is 41.5 cm TL (Séret 1989). Presumably oviparous, like other skates but no other information is available on its biology.|
|Major Threat(s):||Potential bycatch of deepwater shrimp trawl fisheries, although no information is available. Given the restricted range and potentially narrow depth distribution of the species, monitoring should be undertaken to determine whether the fishery is impacting on the population.|
Close monitoring of the bycatch of the deepsea shrimp fishery off Madagascar is required to determine whether the species is taken as bycatch and in what quantities.
The development and implementation of management plans (national and/or regional e.g. under the FAO International Plan of Action for the Conservation and Management of Sharks: IPOA Sharks) are required to facilitate the conservation and sustainable management of all chondrichthyan species in the region.
