Amazing Catching Thousands Tons of Fish With Modern Big Boat - Fastest Giant Net Fishing on the sea

purse seine mackerel fishing Mackerel is an epipelagic fish that swims in schools around coasts and in the open ocean Normally it swims at depths between 10 and 70 meters, but it can swim as deep as 300 meters Mackerel are prolific broadcast spawners and must breed near the surface of the water because the eggs of the females float Individual females lay between 300,000 and 1,500,000 eggs Their eggs and larvae are pelagic, that is, they float free in the open sea The larvae and juvenile mackerel feed on zooplankton As adults, they have sharp teeth and hunt small crustaceans such as copepods, forage fish, shrimp, and squid In turn, they are hunted by larger pelagic animals such as tuna, billfish, sea lions, sharks, and pelicans Mackerel flesh is high in omega-3 oils and is intensively harvested by humans Purse seine fishing is a fishing method in which fish are caught by surrounding them, and a large number of fish can be caught at once It used in the open ocean to target dense schools of single-species pelagic fish like tuna and mackerel A vertical net curtain is used to surround the school of fish, the bottom of which is then drawn together to enclose the fish rather like tightening the cords of a drawstring purse Purse seine fishing in open water is generally considered to be an efficient form of fishing It has no contact with the seabed and can have low levels of bycatch Mackerel are strong swimmers Known in the Latin family as punctulus peces which translates to punctual fish This is due to its punctuality of migration during mating season as it moves from warm to cold waters Atlantic mackerel can swim at a sustained speed of 0.98 meters per second with a burst speed of 5.5 meters per second Mackerels are canned or marketed fresh for human consumption. They are a staple food in Africa They are also processed into fish meal, which is fed to swine and salmon 5 kilograms of jack mackerel are needed to raise 1 kilogram of farmed salmon Let's take a look at how the fish process Frozen processed products are most commonly produced at the cutting edge In the flow of many mackerel machines, they are sorted and boxed The state-of-the-art machinery and quick work are used to freeze fish while preserving its freshness The selected fish are cut into pieces and seasoned with salt and miso to become products Canned foods and processed foods that everyone is familiar with are also made with the cutting edge Reliable human work is included in each process We manufacture safe and reliable products Fermentation is done manually by skilled workers in the factory This is a beam trawl that is rigged to target flatfish on soft sand and muddy seabeds The open beam gear has series of tickler chains towed ahead of the mouth of the net designed to stimulate the fish out of the mud and over the footrope of the trawl In the early days of beam trawling, only one net was towed from the stern of the boat Nowadays, most commercial beam trawlers use two beam trawls towed from long derricks projecting about half as broad as it is long. Being a right-eyed flounder, both its eyes are on the right side of the fish's body, though the eyes are symmetrical just after hatching When yellowtail flounder are first hatched, their eyes are symmetrical with an eye on each side of their head. As the fish grows, it flattens out and the left eye slowly moves over to the right side of its head. After this metamorphosis, the juvenile settles to the ocean bottom. Yellowtail flounder grow faster than most flatfish, up to 22 inches and 2.2 pounds. They can live up to 17 years, although most don't live past age. Yellowtail flounders are fished between late fall and spring, usually with a trawl net or gill net. Hooks are ineffective as their mouths are small. In 2021, commercial landings of yellowtail flounder totaled 1.6 million pounds and were valued at 1.4 million dollars. Yellowtail flounder is sweet and mild while being a source of B vitamins.
