In the first 8 months of the #SeyCCAT lethrinid project only 7 specimens of Yellowlip emperor (Lethrinus xanthochilus) were recored and all of those were from the Amirantes. Very interesting therefore to record two young specimens in the Mahe nearshore trap catch this weekend.

The striking features of the sicklefin lemon shark (Negaprion acutidens) - "kabo roz" - Mahe (11/07/26). This #saveourseasfoundation keystone grant project is enabling enhanced data gathering and understanding of the shark catch of the artisanal fishery. #saveourseasfoundation
Lethrinid catch data really starting to come together nicely. Here the longface emperor (Lethrinus olivaceus) catch demography and length weight modelling (R2 = 0.98).

My father, then Group Captain John Nevill, led the Buccaneer squadrons from RAF Honington to RED Flag in the States in 76/77. He would have loved to see this post.

The sky emperor (Lethrinus mahsena) - "madanm beri" - though relatively common in the local catch is listed as endangered on the IUCN red list, it is important therefore that we ascertain its status here. #SeyCCAT establishing a baseline for the Seychelles lethrinid fishery.
Tiger shark (Galeocerdo cuvier) - "demwazel" - Mahe (09/07/26). This catch survey is supported by a Save Our Seas Foundation Keystone Grant which also enables fisher collaboration in data gathering. #saveourseasfoundation #artisanalfishery #seychelles
