Otoro is a part of bluefin tuna that is the most desirable. It comes from the inside of the belly and it's the fattiest part of the fish. The texture is often described as intensely rich, marbled, and having melt-in-the-mouth properties. Due to these facts, it's traditionally the most expensive part of bluefin tuna. It's often used in sashimi and nigiri, giving the dish a sweeter flavor. Otoro is the best during winter, once the tuna acquires additional body fat. It should always be consumed fresh as it doesn't last too much when frozen. This part of tuna is rarely found outside of Japan.Expand

Akami is a part of bluefin tuna that refers to lean red meat. This is the main part of the fish, so it's more readily available than the other parts, called chūtoro and otoro. It has the least fat out of the whole tuna, which makes it the most affordable. Akami is typically used atop rice in sashimi or nigiri. In a sushi restaurant, if you order maguro (a broad term for tuna), you will get akami from whichever species of tuna they have on hand. This part of tuna also has the most umami tuna flavor of all other, fattier cuts.Expand

Chūtoro is a part of bluefin tuna that refers to medium fatty cuts when served as a part of nigiri or sashimi. The tuna yields otoro (fatty parts from the belly), akami (red meat), and chūtoro, which is a combination of both that's found near the skin on the back and belly. It's a mix of otoro's sweetness and a deep, slightly bitter flavor of akami. This part of bluefin tuna is usually a bit more on the expensive side, and it's typically served on special occasions or festivities. Specifically, the part of the back near the head is called sekami, the center of the back is senaka, and the part near the tail is called seshimo.Expand

A pelagic fish whose typical habitats are temperate and tropical waters, although it may inhabit cold waters as well, xiphias is a species of swordfish that is sourced from the Mediterranean Sea and its embayments (Aegean and Ionian Seas) in Greece. The long and slender sword-like bill is its most recognizable feature, and it is also the reason why this fish was given the name Xiphias gladius, from the Greek xiphos and Latin gladius, both of which translate to sword in English, referring to the characteristic shape of the bill. Xiphias is listed among the fastest fish worldwide, and it is distinguished by a large and heavy, cylindrical body with a pair of both dorsal and anal fins, while the typical coloration of the body is blackish-brown, which gradually becomes paler underneath. Scales and teeth are present in juveniles, while adults lack both of these. Being a carnivorous fish, its diet mostly consists of other fish such as Atlantic mackerel, redfish, silver hake, and barracudinas, but it also preys on crustaceans and squids, all the while using its bill as a means of catching the prey. Known to be a highly migratory species, this fish is an attractive game fish and a highly appreciated seafood delicacy in Greece and beyond, and it is available in both fresh and frozen versions. In Greece, there is an annual ban on swordfish fishing from the beginning of October through January as a protective measure against overfishing of the species.Expand

Northern Albacore tuna is the prized fresh fish originating from the Basque waters. Also known as hegaluzea and bonito del norte, the tuna is white-fleshed, savory, and aromatic. Its skin is dark blue and almost black, but it fades to white along its underside. The meat is succulent and has a bit of fat along the belly. This tuna is individually line-caught from small fishing boats in the Bay of Biscay, and the process is important because it ensures that each fish is the right quality and size. Albacore tuna is often packed in tins with olive oil and salt, making it perfect for everyday eating and enjoying it throughout the year, and locals suggest to just top it with lemon juice and freshly ground pepper. Whether fresh or canned, this tuna is used in the preparation of many Basque dishes and pintxos (pinchos).Expand

Baltic herring (lat. Clupea harengus membras) is a subspecies of the Atlantic herring, but it is smaller and lives in the brackish waters of the Baltic Sea.

It is a staple food source in the Baltic region, featuring in dishes like smoked herring and salads.Expand

Safridia is a species of horse mackerel caught in the Mediterranean Sea waters in Greece, where the safridia fishing season typically takes place between August 15 and the end of January.

This fish is one of the cheaper varieties of fish in Greece, and it is typically fried or grilled with a wide range of spices. The flavor of safridia is often said to be reminiscent of sardines.Expand

Called atún de almadraba in Spanish, wild almadraba bluefin tuna refers primarily to Atlantic bluefin tuna (atún rojo in Spanish) that is caught using an ancient artisan method of fishing known as almadraba. The method uses an intricate maze of interconnecting trap nets that lead the tuna fish to their final destination - a circular central trap surrounded by boats, where only the largest adult tuna are caught and lifted from the nets, while the smaller and younger ones are set free into the ocean, making this technique of fishing sustainable. Almadraba fishing method has been practiced in Andalusia for thousands of years with little to no changes, and it is thought to have been invented by the Phoenicians. Its Spanish name stems from Arabic and means a place of fighting or a place of hitting. Starting in May, the tuna are sourced off the coastline of Cadiz Province, in the towns of Barbate, Tarifa, Conil de la Frontera, and Zahara de Los Atunes, during their migration to warmer spawning-grounds in the Mediterranean waters. The tuna is of the highest quality during this period as the blubber it has built up over the winter months results in meat that is juicy and succulent, with melting texture and an exceptionally sweet flavor. In Spain, the season of almadraba Bluefin tuna is a time of grand celebration and many gastronomic festivities revolving around this culinary delicacy, which is omnipresent in tapa bars and restaurants at this time of the year.Expand

Cornish sardines are caught and processed on the Cornish coast and belong to the species sardina pilchardus. They are olive or metallic green on the back and silvery white on the belly.

When sold, they can be either fresh or frozen, and can be cooked whole, grilled, roasted or barbecued.Expand
