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 ...
Ikejime (活け締め) or ikijime (活き締め) is a method of killing fish that maintains the quality of its meat. [1] The technique originated in Japan, but is now in widespread use. It involves the insertion of a spike quickly and directly into the hindbrain, usually located slightly behind and above the eye, thereby causing immediate brain ...
Human chromosomes painted with DNA from mouse chromosome 11 showing hybridization signals on human chromosomes 17, 5, 2, 7, and 22 and some other chromosomes. That is, an ancestral chromosome broke up into multiple fragments that can still be found in many human chromosomes. [32] FISH can be used to study the evolution of chromosomes. Species ...
Fish preservation is the method of increasing the shelf life of fish and other fish products by applying the principles of different branches of science in order to keep the fish, after it has landed, in a condition wholesome and fit for human consumption. [1][2] Ancient methods of preserving fish included drying, salting, pickling and smoking.
Cuttlefish and squid may also dried this way [4] The amount of drying can vary. In the labtingaw variant, the drying period only lasts a few hours, allowing the fish to retain some moisture and texture. [5] In the lamayo variant, the fish isn't dried at all, but simply marinated in vinegar, garlic and spices. [6] Dried squid
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.
Fisheries management. The goal of fisheries management is to produce sustainable biological, environmental and socioeconomic benefits from renewable aquatic resources. Wild fisheries are classified as renewable when the organisms of interest (e.g., fish, shellfish, amphibians, reptiles and marine mammals) produce an annual biological surplus ...
The basic concept was first used in the 1920s, and is considered one of the seven basic tools of quality control. [5] It is known as a fishbone diagram because of its shape, similar to the side view of a fish skeleton. Mazda Motors famously used an Ishikawa diagram in the development of the Miata sports car. [6]
