Tuna is a broad term that refers to several species of large, fast-swimming fish belonging to the Thunnini tribe. These fish are highly migratory and can be found in both tropical and temperate oceans around the world.

Habitat: Tuna are pelagic fish, meaning they primarily inhabit the open ocean rather than coastal areas. They are known for their ability to traverse vast distances and can be found in both deep and surface waters. Tuna species typically prefer warmer waters but may also inhabit cooler regions depending on the time of year and their migratory patterns.

Where they are caught: Tuna fisheries operate in various oceans and seas around the world, targeting different species of tuna depending on their geographic location and fishing methods:

• Western and Central Pacific Ocean ис one of the largest tuna fishing grounds in the world, with significant catches of species such as yellowfin tuna, bigeye tuna, and skipjack tuna.
• Eastern Pacific Ocean is another important tuna fishing region, with catches of species like yellowfin tuna, skipjack tuna, and albacore tuna.
• Atlantic Ocean and Mediterranean Sea - тuna fisheries in these areas target species such as bluefin tuna, yellowfin tuna, bigeye tuna, and skipjack tuna. Major fishing grounds include the Mediterranean Sea, Gulf of Mexico, Caribbean Sea, and waters off the coasts of countries like Spain, Portugal, France, Japan, and the United States.
• Indian Ocean is another important tuna fishing region, with catches of species like yellowfin tuna, bigeye tuna, skipjack tuna, and albacore tuna.

Types of tuna: There are several species of tuna, each with its own unique characteristics and distribution:

• Bluefin tuna are among the largest and most highly prized tuna species. They are found in both the Atlantic and Pacific Oceans and are known for their rich, fatty flesh. Bluefin tuna are heavily targeted by commercial fisheries and are considered endangered due to overfishing.
• Yellowfin tuna are found in tropical and subtropical waters worldwide. They are prized for their mild flavor and firm texture, making them popular for sashimi, sushi, and canned tuna products.
• Albacore tuna is among the most fished types of tuna. It is found in oceans around the world, mostly in temperate and tropical waters. It is often found in offshore areas, especially in areas with nutrient-rich waters and strong ocean currents. It is known for its extensive migrations, traveling long distances between feeding grounds and spawning grounds. Albacore tuna is prized for its firm meat with a mild flavor.
• Bigeye tuna are found in tropical and subtropical waters of the Atlantic, Pacific, and Indian Oceans. They are known for their large, deep-set eyes and rich, flavorful flesh. Bigeye tuna are targeted by commercial fisheries for their high-quality meat.
• Skipjack tuna are the most abundant and widely caught tuna species. They are found in tropical and warm temperate waters worldwide and are known for their smaller size and more modest flavor compared to other tuna species. Skipjack tuna are commonly used in canned tuna products.

Sardines are small, oily fish belonging to the herring family. Sardines have a distinct flavor that is often described as rich, oily, and slightly salty. They have a firm texture and are known for their high oil content, which gives them a unique taste. Sardines are also prized for their nutritional value, as they are rich in omega-3 fatty acids, protein, vitamins, and minerals.

Habitat: Sardines are found in coastal waters of the Atlantic, Pacific, and Indian Oceans. They typically inhabit temperate and subtropical regions.

Where they are caught: Sardines are caught in various parts of the world:

• Mediterranean Sea is one of the largest sardine fishing grounds in the world, with countries like Spain, Portugal, Italy, and Greece having significant fisheries.
• Pacific Ocean - sardines are also caught in the Pacific Ocean, particularly off the coasts of countries like Japan, Peru, Chile, and the United States (California).
• Atlantic Ocean - sardine fisheries operate in the Atlantic Ocean, targeting species like the European pilchard off the coasts of Europe and North Africa, as well as the Atlantic sardine in regions like South Africa and South America.

Types of sardiness: There are several species of fish commonly referred to as sardines:

• European pilchard: Found in the northeastern Atlantic Ocean and the Mediterranean Sea, European pilchards are known for their small size and rich, oily flesh.
• Atlantic sardine: This species is found in the Atlantic Ocean, particularly off the coasts of South America and South Africa. It is similar in appearance and taste to European pilchards.
• Pacific sardine (Sardinops sagax caeruleus): Pacific sardines are found in the Pacific Ocean, from Alaska to Mexico. They are known for their silver-colored bodies and strong, fishy flavor.

Cod fish, specifically Atlantic cod (Gadus morhua), is a popular and widely consumed species of fish found in cold waters of the North Atlantic Ocean. Cod is known for its mild, slightly sweet flavor and delicate, flaky texture. The flesh of cod is white and lean, with a low oil content compared to some other fish species. Cod's mild taste makes it versatile and adaptable to various cooking methods and flavor profiles. It readily absorbs seasonings and sauces, making it a popular choice in a wide range of culinary preparations.

Habitat: Atlantic cod is primarily found in the North Atlantic Ocean. It inhabits both deep and shallow waters, typically preferring temperatures between 0 to 10°C. Cod is a demersal species, meaning it dwells near the sea floor, often in areas with rocky bottoms or undersea structures where it can find food and shelter.

Where they are caught: Cod fisheries operate in various regions of the North Atlantic Ocean.

Types of cod fish: Atlantic cod (Gadus morhua) is the most famous species of cod that is caught industrially.
