Local products Pla thu (ปลาทู, 'short mackerel') is regarded as an important commercial fish and the most famous product of the province. Mackerel from Samut Songkhram is well known as "Pla Thu Mae Klong." Because the province borders the Bay of Bangkok, which is rich in
plankton, the staple food of this fish species, Samut Songkhram's pla thu have a distinctive characteristic locally called
"na ngo kor hak" (หน้างอ คอหัก, "curved face, broken neck"). This unique trait contributes to their large body size and delicious meat. They can be cooked into a
variety of dishes such as
Pla thu tom madan (ปลาทูต้มมะดัน, 'pla thu in spicy and sour soup'),
Chu chee pla thu (ฉู่ฉี่ปลาทู, 'pla thu in red curry sauce'),
Pla thu sa tia (ปลาทูซาเตี๊ยะ, 'pla thu in sweet black soup'), and even pla thu
burgers made from their meat, a specialty that can only be found in Samut Songkhram. ==Local festivals==
