Minnesota Fishes

 
Bony Fishes (Class Osteichthyes)
 

Osteichthyes is the class of bony fishes. It is characterized by having skeletons composed of bone, not cartilage; gills; a two-chambered heart; and no pelvic girdle. Most have paired lateral and median fins; a terminal mouth; and smooth, overlapping ganoid, cycloid or ctenoid scales.

The class is divided into two subclasses: ray-finned fishes (Actinopterygii) and lobe-finned fishes (Sarcopterygii). The vast majority of extant (living) fishes are ray-finned fishes. There are no lobe-finned fishes in North America.

 
Ray-finned Fishes (Subclass Actinopterygii)
 

Actinopterygii are characterized by having a fin composed of a web of skin supported by bony or horny spines. The subclass includes almost 99% of all species of fish.

There are about 30,000 Actinopterygii species worldwide. In 2011, there were 162 species in Minnesota.

 
Lampreys (Class Hyperoartia)
 

The taxonomy of lampreys is in dispute. Some taxonomists place lampreys in the class Cephalaspidomorphi. Most consider this taxon extinct. Most now place lampreys in the class Hyperoartia.

Though they look like eels, lampreys are jawless fish. They are characterized by having a toothed, funnel-like, sucking mouth.

 
Traditional Classification
 

The division of fishes into five classes, with ray-finned fishes (Actinopterygii) a single subclass of bony fishes (Osteichthyes) is the traditional classification, Linnaean taxonomy. Under Linnaean taxonomy, taxa are grouped into sets or classes by characteristics shared among their members. It is the scheme followed by most non-specialist sources. Under this scheme the grouping of all fish also contains tetrapods (Superclass Tetrapoda), which are not fish. In taxonomic terms, the group is paraphyletic. Most taxonomists avoid paraphyletic groups whenever possible.

A newer classification scheme, the International Code of Phylogenetic Nomenclature, Phylocode for short, emphasizes ancestry at the expense of descriptive characteristics. Phylocode seeks to regulate the naming of clades, with the naming of species remaining the responsibility of the rank-based Nomenclature codes (ICN, ICZN, ICNB, ICTV). The most recent Phylocode draft was released in 2019. Few reputable sources for taxonomic classification follow Phylocode. Two that do are Integrated Taxonomic Information System (ITIS) and National Center for Biotechnology Information (NCBI). As of February, 2020, it remains uncertain whether Phylocode will ever be widely adopted.

Plural of Fish

We were all taught in elementary school that the plural of moose is moose and the plural of fish is fish. That remains true – mostly.

When the word fish refers to individual organisms, like those found on ice in a grocery store, the plural of those organisms is fish. When the word refers to a taxonomic grouping, such as the species bluegill (Lepomis macrochirus) and brook trout (Salvelinus fontinalis), the plural of those groupings is fishes.

Brook trout
     

Brook trout is a medium-sized freshwater fish. It is native to eastern United States and southern Canada from Newfoundland west to eastern Minnesota, south to northern New Jersey and eastern Iowa, and also south along the Appalachian Mountains to northern Georgia. It is a popular sport fish and has been stocked around the world since the 1800s. It is now widely distributed and locally established across Europe, Canada, and the United States. In Minnesota it is most common in the northeast. It is found in small, spring-fed streams that are cool, no more than 66°F; well oxygenated; and clear, mostly free of siltation.

Brook trout is a medium-sized freshwater fish. It lives an average of 6 to 8 years in the wild in its native range, but has been known to survive up to 24 years in other areas. The average length at maturity is 15 to 20, though in Minnesota the average length is reported as just 8 to 10. The body is long, streamlined, and slightly compressed laterally. The mouth is large. During breeding season the male develops a hook on the lower jaw. The back is olive-green to dark brown or almost black with numerous worm-like pale spots. The sides are lighter with numerous round pale spots and smaller red spots. Each red spot has a thin bluish halo. The belly is silvery white. During spawning season the sides and fins of the male often become bright orangish-red.
