Trophy Fish?

[Big Kahunaz]

While living in Galveston, I recall stumbling upon a website advertising guided trips to fish holding tanks placed offshore where potential trophy fish would be kept and fisherman could pay different rates (wasn't cheap) for different target species: Tuna/Marlin/Grouper etc. I can't remember the name of the site or what exactly it related to on the google search engine. If anyone has any idea what im talking about....feel free to help out.

I recall it being some sort of pen setup offshore. Not fish farms for food.
