It might have been Morocco, which has a large Atlantic & a lesser Mediterranean coast line.

Their Sardine fishing rights are extremely important to their quite poor economy.
If you look at virtually all brands of canned Sardines on sale here, they are mostly from Morocco, with Essaouira being the main port for it with large canning factories there.
It is a great place to go for a really fresh fish meal with a line of restaurants virtually on the docks, where if you go in, they send you off with a waiter to pick your own fish from the numerous stalls on the dockside and then cook it to your requirements.
There is an interesting fortification there as well, dating back to Phoenician times and with an interesting selection of old Spanish, mainly cannons still there!
It was my favourite town in Morocco!
