in 1993, pangasius was one of two extant genera (along with helicophagus) in the family pangasiidae. At this point, it was split into four subgenera. Pangasius (pangasianodon) included p. Gigas and p. Hypophthalmus and was diagnosed by the absence of mandibular barbels, the absence of teeth in adults and the presence of a single-lobed swimbladder. Pangasius (pteropangasius) included p. Micronema and p. Pleurotaenia and was diagnosed by four lobes in the swimbladder and with multiple segments in the last lobe. Pangasius (neopangasius) included p. Nieuwenhuisii, p. Humeralis, p. Lithostoma, p. Kinabatanganensis, diagnosed by palatal teeth arranged in a single large patch and high vertebral counts. Pangasius (pangasius) was the final subgenus and had no diagnostic features, containing the remaining species.[2] these subgeneric classifications were confirmed in 2000 except for neopangasius, found to be polyphyletic and to be part of pangasius (pangasius), thus leaving three subgenera.

salmon is the common name for several species of ray-finned fish in the family salmonidae. Other fish in the same family include trout, char, grayling and whitefish. Salmon are native to tributaries of the north atlantic (genus salmo) and pacific ocean (genus oncorhynchus). Many species of salmon have been introduced into non-native environments such as the great lakes of north america and patagonia in south america. Salmon are intensively farmed in many parts of the world.
typically, salmon are anadromous: they hatch in fresh water, migrate to the ocean, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water through their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn. Tracking studies have shown this to be mostly true. A portion of a returning salmon run may stray and spawn in different freshwater systems; the percent of straying depends on the species of salmon

mackerel is a common name applied to a number of different species of pelagic fish, mostly from the family scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment.
mackerel species typically have vertical stripes on their backs and deeply forked tails. Many are restricted in their distribution ranges and live in separate populations or fish stocks based on geography. Some stocks migrate in large schools along the coast to suitable spawning grounds, where they spawn in fairly shallow waters. After spawning they return the way they came in smaller schools to suitable feeding grounds, often near an area of upwelling. From there they may move offshore into deeper waters and spend the winter in relative inactivity. Other stocks migrate across oceans.
smaller mackerel are forage fish for larger predators, including larger mackerel and atlantic cod. Flocks of seabirds, whales, dolphins, sharks, and schools of larger fish such as tuna and marlin follow mackerel schools and attack them in sophisticated and cooperative ways. Mackerel flesh is high in omega-3 oils and is intensively harvested by humans. In 2009, over 5 million tons were landed by commercial fishermen. Sport fishermen value the fighting abilities of the king mackerel.
