I am looking for a recipe

Hello all,
Has anyone tried this recipe of Cou Cou and flying fish? It is a famous cuisine of Barbados. My husband told me about this. He had been to Barbados for some official purpose, and he had happened to taste this dish. He loved it so much that now he has asked me to make it for him. I checked on the internet for a good recipe, but it’s too confusing. I finally selected this one, which I feel is the authentic one,http://thecrane.com/blog/2016/07/13/barbados-recipes-cou-cou-flying-fish/. The recipe looks simple. I want to know if anyone has a better version of this dish.

Where do you intend on getting flying fish and I can't imagine how you think you will get flying fish big enough to 'scale, bone and butterfly'.
