These include krill, crab larvae, jellyfish, sardines, anchovies, mackerels, small tunas, and squid. Major species abound such as mackerels, sardines, squids, prawns, crabs, shells, oysters and others. Shrimp, sardines, mackerels, carangid, croakers and other varieties are available. In the Cap Bon, people enjoy tuna, anchovies, sardines, sea bass and mackerels. Like other mackerels, reproduction in the Atlantic mackerel is oviparous. Other non-kosher fish include catfish, eels, Pacific cod, snake mackerels and puffer fish. The type species for scombroid mackerels is the Atlantic mackerel, "Scomber scombrus". Predators include large, deep-roving sharks, cutthroat eels, merluccid hakes, and snake mackerels. The Atlantic mackerel ("caballa"), sardine ("sardine"), and Jack mackerels ("chicharros") are also consumed frequently. Fish "kinilaw" typically use "tanigue" (Spanish mackerels), "malasugi" (marlins or swordfish), and anchovies. The Gempylidae are a family of perciform fishes, commonly known as snake mackerels or escolars. A large number of migratory birds, catfish and mackerels were once abundant in these waters. Just two species account for about 75% of the total catch of scombroid mackerels. Suitably designed trollers can also catch mackerels effectively when they swim near the surface. They account for about half the total capture production of scombroid mackerels.
