The perch-like (Perciformes (= Serraniformes sensu Li et al.)), Also called perch fish , are an order of bony fish . The taxonomic name is made up of the Greek " perke " ( perch ) and the Latin " forma " (form). Perch-like live both in fresh water and in the sea. The best-known Central European perch-like include the river perch and the pikeperch .

The perch-like were for a long time a poly- and paraphyletic collective taxon, in which all families were housed, which do not have any of the derived characteristics that define the other barbed-fins or perch-related orders. Nelson gives over 10,000 species, over 1500 genera, 160 families and 20 suborders for perch-like in the traditional sense. With a third of the fish species, they were the largest fish order and also the most species-rich order of the vertebrates (Vertebrata).

At the beginning of 2013 Ricardo Betancur-R. and colleagues developed a new system of bony fish based on the comparison of nuclear and mitochondrial DNA , in which the Perciformes form a monophyletic taxon around the core group of the perch (Percidae). From all other the Percoidei assigned Untertaxa only remain groupers (Serranidae) and the weever (Trachinidae), as well as the Antarctic fish (Notothenioidei) and Aalmutterverwandten (Zoarcales) left. Instead, almost all families of the former armored cheeks (Scorpaeniformes) (with the exception of the flying cocks (Dactylopteridae), which came to the pipefish-like (Syngnathiformes)) were assigned to the perch-like, as well as the stickleback-like (Gasterosteales), which represent the sister group of the eel mother relatives. A few months later, Thomas J. Near and colleagues in their work on the diversification and phylogeny of the Acanthomorphata came to the same conclusion with regard to the composition of the Perciformes.


The body shape of the perch-like can be very different. It can be moderately high back (river perch), spindle-shaped (pikeperch) or eel-like elongated ( eel mother relatives ). Typically, perch-like have two separate dorsal and anal fin, the front part of which is supported by spiny rays. An adipose fin is always missing. The pelvic fins are on the chest, but can also be absent. The caudal fin has a maximum of 17 fin rays. The body of most species is covered by ctenoid scales (comb scales), in some families there are cycloid scales (round scales). There are also scaly species. There are no bones or connective tissue ossifications between the muscle segments without contact with the spine.

Internal system

In the following, the classification of perch-like is based on an update of the classification published in July 2017 by Ricardo Betancur-R. and colleagues reproduced:
