In Portugal and Spain, there are quite strict quota regulations limiting fishing to late Spring, Summer and early Autumn: quota regulations for sardines. Those quotas regulate the fishing of "free range" sardines.
However, some restaurants in Portugal offer sardines also in the Winter. Where would those sardines come from? Since frozen sardines taste quite differently — badly, in my opinion — compared to fresh ones, could those stocks come from farmed sardines (aquaculture)?
