October is always a fun month for seafood. Some migratory fishes like swordfish and tuna follow the warmer gulf stream waters (and their food source) all the way to the northern Atlantic and sometimes further to Iceland and Europe. In swordfish, their diet can change also as they incorporate more shellfish and therefore more carotenes which can turn their flesh an orangish color. They call these fish "pumpkins" which I always thought was appropriate for October. Some think this gives them even more flavor. I like them either way.
October (and colder weather) will bring an end to some fisheries like soft shell crabs and soon to follow will be wild king salmon and halibut from the north Pacific.
The extremely heavy rains (and hurricane) put a temporary kabosh on clamming and shrimping in the mid-Atlantic states but rumor has it we will have more fresh shrimp next week, along with our normal array of excellent fresh products.
