Fasting 001: A feast or a fast?

This year, the Feast of the Dormition of the Theotokos falls on a Wednesday - at least for those of us who follow the Julian calendar. This presents an interesting problem: is today a feast or a fast? On the one hand, it is definitely a feast in liturgical terms. On the other hand, Wednesday is usually a fast, and so many popular calendars show that fish is allowed, implying that meat is not. Thus, it may appear - and many treat it as such - that if a liturgical fast falls on a Wednesday or a Friday, with some exceptions, then we still keep the fast, however relaxed by eating fish but not poultry, meat, or other animal products, such as cheese and eggs. Is this correct?
