Mattanza in Sicily, an etching La pêche du thon ("Tuna Fishing", 1782) by Jean-Pierre Houël. The practice of mattanza is an elaborate and age-old fishing technique for trapping and catching Atlantic bluefin tuna that can be traced back to the Phoenicians.
It is a traditional form of fishing practiced mainly in southeastern Spain (Andalusia, Murcia and southern Valencian Community), Morocco and southern Portugal (the Algarve).

A fishing sinker, plummet, or knoch is a weight used in conjunction with a fishing lure or hook to increase its rate of sink, anchoring ability, and/or casting distance. Fishing sinkers may be as small as 1 gram (0.035 oz) for applications in shallow water, and even smaller for fly fishing applications, or as large as several pounds (>1 kg) or ...
The Atlantic bluefin tuna is a close relative of one of the other two bluefin tuna species, the Pacific bluefin tuna. The southern bluefin tuna , on the other hand, is more closely related to other tuna species such as yellowfin tuna and bigeye tuna , and the similarities between the southern and northern species are due to convergent evolution.
World War II interrupted fishing and after the war the technical developments in commercial fishing in the North Sea reduced herring and mackerel stocks and led to the disappearance of tunny. [1] In 2000 a 76-year-old pensioner using a fishing rod for the first time landed the largest tuna caught off the British Isles for nearly 50
Once the fish is hooked (often colloquially called "fish-on"), any struggles and attempts to escape will pull along the line, causing the bite indicator to signal the angler, who jerks the fishing rod back to further deepen the hook anchorage (i.e. "setting the hook") and then tries to retrieve the line back, pulling the fish closer in the ...
The Carolina rig. A rig is an arrangement of items used for fishing. It can be assembled of one or more lines, hooks, sinkers, bobbers, swivels, lures, beads, and other fishing tackle. A rig might be held by a rod, by hand, or attached to a boat or pier. Some rigs are designed to float near the surface of the water, others are designed to sink ...
Southern bluefin tuna, along with other marine teleost fish, have acquired a variety of proteins and mechanisms which allow the secretion of ions through the gill epithelium. [6] Due to the southern bluefin tuna's high metabolic need, ions must be taken up relatively quickly to ensure sufficient concentrations for cellular function.
