Age determination in fish. Removing an otolith from a red snapper to determine its age. Knowledge of fish age characteristics is necessary for stock assessments, and to develop management or conservation plans. Size is generally associated with age; however, there are variations in size at any particular age for most fish species making it ...
Fluorescence. in situ. hybridization. A metaphase cell positive for the bcr/abl rearrangement (associated with chronic myelogenous leukemia) using FISH. The chromosomes can be seen in blue. The chromosome that is labeled with green and red spots (upper left) is the one where the rearrangement is present.
The principle setup of a light sheet fluorescence microscope. Light sheet fluorescence microscopy ( LSFM) is a fluorescence microscopy technique with an intermediate-to-high [1] optical resolution, but good optical sectioning capabilities and high speed. In contrast to epifluorescence microscopy only a thin slice (usually a few hundred ...
Hangetsu-giri; half-moon cut, cut into round slices which are cut in half. Aname-giri ; diagonal cut, cut at a 45-degree angle to make oval slices. Icho-giri; gingko leaf cut, cut into round slices which are cut into quarters. Koguchigiri; small edge cuts into tiny round slices. Kushigatagiri; wedge cut or comb cut.
Fish fillets comprise the flesh of the fish, which is the skeletal muscles and fat as opposed to the bones and organs. Fillets are usually obtained by slicing the fish parallel to the spine, rather than perpendicular to the spine as is the case with steaks. The remaining bones with the attached flesh is called the "frame", and is often used to ...
Commercial fishing showing the abundance of fish species caught using a trawling method. Unsustainable fishing methods refers to the use of various fishing methods to capture or harvest fish at a rate which is unsustainable for fish populations. [1] These methods facilitate destructive fishing practices that damage ecosystems within the ocean ...
Fishing techniques are methods for catching fish. The term may also be applied to methods for catching other aquatic animals such as molluscs ( shellfish, squid, octopus) and edible marine invertebrates . Fishing techniques include hand-gathering, spearfishing, netting, angling and trapping.
A fishing line is any flexible, high-tensile cord used in angling to tether and pull in fish, in conjunction with at least one hook. Fishing lines are usually pulled by and stored in a reel, but can also be retrieved by hand, with a fixed attachment to the end of a rod, or via a motorized trolling outrigger . Fishing lines generally resemble a ...
