Congressman Soto passed a law to protect billfish, such as marlin, spearfish, and sailfish. Bony fish included mahi mahi, conger eels, rattails, ancestral billfish, cod, hake, and rockfish. Other fish like the tunas, billfish and Lamnid sharks also possess this ability. Tuna, mahi-mahi, billfish, barracuda and sharks reside outside the lagoon. Examples of larger pelagic fish are tuna, billfish, king mackerel, sharks, and large rays. The major U.S. catch stock is tuna, though billfish, swordfish, and shark are also caught. Based in Hawaii, a longline fishery for tuna and billfish were popular. Adult swordfish have no teeth, and other billfish have only small file-like teeth. They are in turn eaten by billfish, mackerel, and sharks. Most recreational fishermen now tag and release billfish. They are a popular sport fish of the billfish category, though elusive. It is considered the most tropical billfish species. They are, therefore, described as billfish in sport-fishing circles. The term billfish refers to the fishes of the families Xiphiidae and Istiophoridae. Many fisherman have been injured, some seriously, by a billfish thrashing its bill about.
