Fish are highly perishable. A central concern of fish processing is to prevent fish from deteriorating, and this remains an underlying concern during other processing operations. Fish processing can be subdivided into fish handling, which is the preliminary processing of raw fish, and the manufacture of fish products.
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 ...
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.
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.
The use of detergents at a 0.1% concentration is commonly used to enhance the tissue permeability such as Tween-20 or Triton X-100. [ 12 ] It is critical for the hybridization process to have all optimal conditions to have a successful in situ result, including temperature, pH, salt concentration, and time of the hybridization reaction.
Canned fish. Canned or tinned fish are food fish which have been processed, sealed in an airtight container such as a sealed tin can, and subjected to heat. Canning is a method of preserving food, and provides a typical shelf life ranging from one to five years. They are usually opened via a can opener, but sometimes have a pull-tab so that ...
Chromogenic in situ hybridization (CISH) is a cytogenetic technique that combines the chromogenic signal detection method of immunohistochemistry (IHC) techniques with in situ hybridization. [1][2] It was developed around the year 2000 as an alternative to fluorescence in situ hybridization (FISH) for detection of HER-2/neu oncogene ...
Tilapia (/ t ɪ ˈ l ɑː p i ə / tih-LAH-pee-ə) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini.
