A medieval view of fish processing, by Peter Brueghel the Elder (1556). There is evidence humans have been processing fish since the early Holocene. For example, fishbones (c. 8140–7550 BP, uncalibrated) at Atlit-Yam, a submerged Neolithic site off Israel, have been analysed. What emerged was a picture of "a pile of fish gutted and processed ...

They are among the largest fish, with some species reaching lengths of about 7–7.6 m (23–25 ft). [2]
Electrofishing. Scientists carrying out a population and species survey using electrofishing equipment. Electrofishing is a fishing technique that uses direct current electricity flowing between a submerged cathode and anode. This affects the movements of nearby fish so that they swim toward the anode, where they can be caught or stunned.
Salted fish, such as kippered herring or dried and salted cod, is fish cured with dry salt and thus preserved for later eating. Drying or salting, either with dry salt or with brine, was the only widely available method of preserving fish until the 19th century. Dried fish and salted fish (or fish both dried and salted) are a staple of diets in ...

[ 5 ] Scottish zoologist Andrew Smith named the genus in 1840.
The oldest archeological findings of fish fermentation are 9,200 years old and originate from the south of today's Sweden. [5] [6] More recent examples include garum, a fermented fish sauce made by the ancient Greeks and Romans, and Worcestershire sauce, which also contains fermented fish.
Blade (archaeology) In archaeology, a blade is a type of stone tool created by striking a long narrow flake from a stone core. This process of reducing the stone and producing the blades is called lithic reduction. Archaeologists use this process of flintknapping to analyze blades and observe their technological uses for historical purposes.
The largetooth sawfish is a predator that feeds on fish, molluscs and crustaceans. [4] The "saw" can be used both to stir up the bottom to find prey and to slash at groups of fish. [6] [12] Sawfish are docile and harmless to humans, except when captured where they can inflict serious injuries when defending themselves with the "saw". [12] [26]
