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.
This 16th-century fish stall shows many traditional fish products. The term fish processing refers to the processes associated with fish and fish products between the time fish are caught or harvested, and the time the final product is delivered to the customer. Although the term refers specifically to fish, in practice it is extended to cover ...
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. Fluorescence in situ hybridization (FISH) is a molecular cytogenetic technique ...
The term "hardy", used alone, refers to a cutting chisel used in the square hole of the anvil. Other bottom tools are identified by function. Typical hardy tools include chisels and bending drifts. They are generally used with a matching top tool . Different hardy tools are used to form and cut metal. The swage is used to make metal a specific ...
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.

Pristis perotteti J. P. Müller & Henle, 1841. The largetooth sawfish (Pristis pristis, syn. P. microdon and P. perotteti) is a species of sawfish in the family Pristidae. It is found worldwide in tropical and subtropical coastal regions, but also enters freshwater. It has declined drastically and is now critically endangered. [1][3][4]
A 1.3 m (4.3 ft) sawfish had a 33 cm (13 in) catfish in its stomach. [71] It had been suggested that sawfish use their saw to dig/rake in the bottom for prey, [79] but this was not observed during a 2012 study, [74] or supported by later hydrodynamic studies. [77] Large sawfish often have rostral teeth with tips that are notably worn. [35]
A 52 mm (2.0 in) hole saw with pilot bit. A 115 mm (4.5 in) diamond hole saw. A hole saw (also styled holesaw ), also known as a hole cutter, [ 1] is a saw blade of annular (ring) shape, whose annular kerf creates a hole in the workpiece without having to cut up the core material. It is used in a drill. Hole saws typically have a pilot drill ...
