“Perca Fluviatilis/Der Barsch/La Perche/The Perch” (plate 52), copper engraving made by Ludwig Schmidt after the drawing of Krüger jr, for Markus Elieser Bloch’s “Allgemeine Naturgeschichte der Fische” published in Berlin between 1782 and 1795. With original hand colouring. Size: 19 x 38 cm.
Bloch’s work on the “Allgemeine Naturgeschichte der Fische” occupied a considerable portion of his life, and is considered to have laid the foundations of the science of ichthyology. The publication was encouraged by a large subscription, and it passed rapidly through five editions in German and in French. Bloch made little or no alteration in the systematic arrangement of Peter Artedi and Carl Linnaeus, although he was disposed to introduce into the classification some modifications depending on the structure of the gills. To the number of genera before established, he found it necessary to add nineteen new ones, and he described 276 species new to science, many of them inhabitants of the remotest parts of the ocean, and by the brilliancy of their colours, or the singularity of their forms, as much objects of popular admiration as of scientific curiosity.
Bloch is considered the most important ichthyologist of the 18th century.
Perca fluviatilis, also known as the European perch, is a species of freshwater fish belonging to the family Percidae, which also includes walleye and yellow perch. It is native to Europe and is commonly found in freshwater environments such as rivers, lakes, and ponds. The European perch is a predatory fish that feeds on a variety of small organisms such as insects, crustaceans, and small fish. It typically grows to around 30-40 centimeters in length and can weigh up to 1 kilogram. The European perch is an important sport fish species for anglers, and is also valued for its meat, which is often used in dishes such as fish cakes and fish stews.
