Perch is a common name for fish of the genus Perca, freshwater gamefish belonging to the family Percidae. The perch, of which three species occur in different geographical areas, lend their name to a large order of vertebrates: the Perciformes, from the Greek: πέρκη meaning perch, the Latin forma meaning shape. Many species of freshwater gamefish less resemble perch, but belong to different genera. In fact, the saltwater-dwelling red drum is 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, P. fluviatilis. Most authorities recognize three species within the perch genus: The European perch is found in Europe and Asia; this species is greenish in color with dark vertical bars on its sides with a red or orange coloring in the tips of its fins. The European perch has been introduced in New Zealand and Australia, where it is known as the redfin perch or English perch.

In Australia, larger specimens have been bred, but the species grows heavier than 2.7 kg. The Balkhash perch is found in Kazakhstan and China, it is similar to the European perch, grows to a comparable size. The yellow perch and paler than the European perch, is found in North America. In northern areas, it is sometimes referred to as the lake perch; this species is prized for its food quality and has been raised in hatcheries and introduced into areas in which it is not native. Yellow perch are identical in appearance to European perch, but have a more yellow coloring; these fish only reach a size of about 38 cm and 1 kg. The general body type of a perch is somewhat 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, two lidless eyes. On the posterior sides are the opercular series, which protect the gills, the lateral line system, sensitive to vibrations in the water; the kidney of the perch forms a head, caudal to the gills.

Perch have paired pectoral and pelvic fins, two dorsal fins, the first one spiny and the second soft. These two fins joined. Perch are carnivorous fish most found in small ponds, streams, or rivers; these fish feed on smaller fish, shellfish, or insect larvae, but can be caught with nearly any bait. They spawn during the spring, when the females lay strings of eggs in covered areas such as near branches or underwater plants. Perch have a wide distribution throughout the world, are plentiful in the Great Lakes Lake Erie. Perch are a popular sport fish species, they are known to put up a fight, to be good for eating. They can be caught with a variety of methods, including float fishing, lure fishing, legering. Fly fishing for perch using patterns that imitate small fry or invertebrates can be successful; the record weight for this fish in Britain is 2.81 kg, the Netherlands 3.05 kg, in America 2.83 kg. Perch grow to around 50 cm and 2.3 kg or more, but the most common size caught are around 30 cm and 0.45 kg or less and anything over 40 cm and 0.9 kg is considered a prize catch.

Elvaston Castle is a stately home in Elvaston, England. The Gothic Revival castle and surrounding parkland is run and owned by Derbyshire County Council as a country park known as, Elvaston Castle Country Park; the country park has 200 acres of woodlands and formal gardens. The centrepiece of the estate is the Grade II* Listed Elvaston Castle; the castle has fallen into disrepair. Derbyshire County Council estimates the castle and estate requires at least £6.1 million of work and materials in essential repairs, with a maximum permitted overspend of 7% greater if it is decided to re-open the building to the public or sell it in repaired form. Until the 16th century the estate was held by the Shelford Priory. After the Dissolution of the Monasteries the Crown sold the priory and its estates in 1538 to Sir Michael Stanhope of Rampton, Nottinghamshire. Sir John Stanhope granted the estate to his second son Sir John Stanhope, High Sheriff of Derbyshire, in 1629; the manor house was built for the latter Sir John in 1633.

This Elizabethan-style house was redesigned and extended in a grand Gothic Revival style by James Wyatt in the early 19th century for the Charles Stanhope, 3rd Earl of Harrington. Wyatt designed a new wing, a new great hall, most of the interiors of the castle, but died before work was completed, his designs were carried out by Robert Walker between 1815 and 1829. Further modifications were made in the 1836 by the architect Lewis Nockalls Cottingham; this was the final modification and created the castle today. During World War II, the house was turned into a teacher training college after the original college in Derby was evacuated; the college vacated the house in 1947, after which time it remained empty for the next two decades until its sale, starting a steady decline that continues to this day. The 3rd Earl, approached Humphry Repton to remodel the grounds of the Castle, Repton turned down the commission due to the flatness of the estate, which he found daunting. In 1830, Charles Stanhope, 4th Earl of Harrington commissioned the untried landscape gardener William Barron, to redesign the gardens.

The Fourth Earl caused scandal by marrying an actress 17 years his junior: Maria Foote. Maria and Charles are described as "inseparable and besotted". Barron would spend the next 20 years working on the gardens; the Fourth Earl and his Countess valued their garden for the romantic seclusion it afforded them, however following the death of their only son aged 4, the couple isolated themselves at the castle, never leaving and forbidding anyone from entering the grounds. Following the Fourth Earl's death in 1851, his brother, Leicester Stanhope, 5th Earl of Harrington, opened the gardens to the public, they became renowned as "a Gothic paradise", are Grade II Listed. The estate contains over 50 structures, including stables, kennels, a walled garden, a home farm, several cottages, gatelodges, an ice house and a boathouse; the gardens are listed Grade II* on the Register of Historic Parks and Gardens. Following the Countryside Act 1968, the estate was sold in 1969 by William Stanhope, 11th Earl of Harrington to Derbyshire County Council.

The Countryside Act proposed the creation of "country parks", "for the enjoyment of the countryside by the public". The council opened the estate to the public in 1970 and have operated it since as Elvaston Castle Country Park. In 1969, Elvaston was used as a location for Ken Russell's film adaptation of the D. H. Lawrence novel Women in Love; the country park is threatened with closure. The deterioration of the castle and estate which started after World War II continued under the care of Derbyshire County Council. Derbyshire County Council claims that it cannot afford to repair and maintain the building and country park. Since 2000, the council has been marketing the estate for sale to private companies; the latest of these is an attempt to turn the Castle into the Park into golf courses. This is being fiercely contested by "The Friends of Elvaston Castle" on behalf of the local community; the £3,000,000 repair work needed in 2000 was not performed. The castle is not open to the public. Derbyshire County Council acknowledges the "ever increasing backlog of maintenance and outstanding repair work".

The cost of repair work has spiraled and as of November 2010, the council estimates the castle needs £6.422 million of work and materials in essential repairs. The castle is thought by some to be haunted: various professional investigations have been conducted in the castle, with phenomena being reported including unexplained noises, unexplained apparitions, people being pushed and things being
