Perch is a common name for fish of the genus Perca, freshwater gamefish belonging to the family Percidae. The perch, of which there are three species in different geographical areas, lend their name to a large order of vertebrates: the Perciformes, from the Greek perke meaning spotted, and the Latin forma meaning shape. Many species of freshwater gamefish more or less resemble perch, but belong to different genera. In fact, the exclusively saltwater dwelling red drum is often referred to as a red perch, though by definition perch are freshwater fish. Though many fish are referred to as perch as a common name, to be considered a true perch, the fish must be of the family Percidae.

The type species for this genus is the European perch, Perca fluviatilis.

Anatomy[edit]

The general body type of a perch is somewhat long and rounded. True perch have "rough" or ctenoid scales. On the anterior side of the head are the maxilla and lower mandible for the mouth, a pair of nostrils, and two lidless eyes. On the posterior sides are the opercula, which protect the gills, and the lateral line system, which is sensitive to vibrations in the water. They have paired pectoral and pelvic fins, and two dorsal fins, the first one spiny and the second soft. These two fins can be separate or joined.

Habits[edit]

Perch are carnivorous fish that are most commonly found in small ponds, lakes, streams, or rivers. These fish feed on smaller fish, shellfish, or insect larvae, but can be caught with nearly any bait. They commonly spawn during the spring, when the females lay strings of eggs in covered areas such as near branches or underwater plants. Even though Perch can be found all over the world, they are most likely found in the Great Lakes, Particularly in Lake Erie.

Fishing[edit]

Perch are sought-after by fishermen both for sport and for food. They can be caught with a variety of methods, but the two best methods are perhaps float fishing and lure fishing. The best way is to use a small hook and cast into the weeds just before the drop off. When fishing with a float, the angler will want to have a disgorger; perch are notorious for swallowing the hook, and will need aid of a disgorger or forceps for unhooking. In many parts of the world, they are also a favorite species among ice fishermen. They will take a variety of baits, including minnows, worms, maggots, goldfish, pieces of raw bacon, and softshell crayfish, but seem to prefer small fish, lobworms, red maggots, and lures. The record weight for this fish in Britain is 5 lb, 15 oz, and in America 6 lb 4 oz.

Perch grow to around 5 lb (2.3 kg) or more, but the most common fish to be caught are around 1 lb (0.45 kg) or less, and anything over 2 lb (0.91 kg) is considered a prize catch.

As food[edit]

In the aquarium[edit]

Perch are great fish to keep in aquarium as long as proper conditions are met. When, you first bring yours home be sure to put it in a quarantine tank for 2-3 weeks to ensure no parasites are residing inside. They should only be kept in tanks of 30 gallons if kept alone and a 55 if kept with other fish. Since this is a predatory fish it must be feed live fish. However, if you obtain a specimen about an inch or 2 long you may be able to wean it onto pellets. Notwithstanding that information, you must supplement its diet with live fish occasionally. Possible tank mates include sunfish, plecos, bass small enough not to swallow the perch, convict cichlids, and other fish too large to be eaten and small enough not to eat the perch. Also, all tank mates must be robust enough to handle the somewhat aggressive tendency's. Perch are great unique pets for any new aquarium.
