A family of fish where several rays of the pectoral fins are detached
and elongated, sometimes greatly elongated. These "pectoral rays" are thought
useful for feeling out food. Threadfins are found in the Indo Pacific and
the Atlantic, several along the east coast of the U.S.. Most are salt water
fish but a few live in rivers and others may enter rivers at times.

This Indo-West Pacific fish is common from the Persian Gulf to Papua New
Guinea and along the north coast Australia. It enters freshwater during
the breeding season so it's sometimes listed as a freshwater fish. It can
grow to 6-1/2 feet but the photo specimen was 13 inches and weighed
11 ounces. This fish is highly commercial, both wild catch and
aquaculture, and frozen ones from Vietnam are found in Asian markets in
Los Angeles. Packages I've purchased were labeled "Threadfin Bream" which
they clearly are not.

Paradise Threadfin -
This Indo-West Pacific fish is found from Pakistan to Vietnam. It enters freshwater during the breeding season so it's sometimes listed as a freshwater fish. It can get over 10 inches long but the photo specimen was 8-1/4 inches and weighed 3.3 ounces. Another in the package of frozen fish from Vietnam was 10-1/2 inches and 7.9 ounces but was not photographed because the tail fins had been clipped to fit the package. Prep & Cooking Details.
