Summary
Leuciscus idus (orfe) are a large-bodied freshwater fish native to Europe. They are valued as a sport fish in many countries and have been introduced to a number of locations for this purpose. Concerns have been raised about their potential to damage to native aquatic ecosystems but there seems to be a lack of information regarding any proven effects.
Species Description
Orfe are a chunky fish, with the back and belly dinstinctly arched. The head is small and bluntly pointed, and the tail has a definite fork in it.

Two colour forms exist. The wild form is a greyish-olive colour on the back and upper sides, paling to silver on the sides and a silvery-white on the belly. Both anal and pelvic fins are a reddish colour. The ornamental variety of orfe has a bright orange back, silvery-orange sides and belly, and bright orange tail and dorsal fin. These two colour morphs are known as 'silver orfe' and 'golden orfe' respectively. Golden orfe populations may revert to the wild colouration over time (McDowall, 2000).

Notes
The maximum reported age for this species is 18 years, and the maximum published weight is 4kg (FishBase, 2004).
Lifecycle Stages
Matures at three to four years of age. Spawning occurs in spring (McDowall, 2000).
Uses
A popular sporting fish among coarse anglers (McDowall, 2000), and in some areas of Europe there is also commercial fishery production (McDowall, 1990). The golden orfe variant is valued as an ornamental fish, as it is just as suitable as goldfish for small ponds (McDowall, 1990).
Habitat Description
Orfe inhabit clear, clean pools of medium-to-large rivers, ponds and lakes (FishBase, 2004). Retreats into deep holes during winter (McDowall, 2000).
Reproduction
Spawns in schools over weed beds or gravel in shallow areas. Produces thousands of pale yellow eggs c. 2mm in diameter. Hatching occurs in one to two weeks, producing young fish 8-10mm long (McDowall, 2000).
Nutrition
Feeds on crustaceans, insect larvae, worms, snails as well as some fish and vegetation (McDowall, 2000).
Pathway
There have been instances of orfe being illegally introduced to new locations by anglers.Golden orfe are valued as ornamental pond fish

General Impacts
There is no information regarding the impacts of orfe in New Zealand as it is confined to one location. Most concerns appear to be based on the fact that it is in the same family as the highly invasive European carp (Cyprinus carpio), which has caused damage to some aquatic ecosystems where it has been introduced Australia, New Zealand and the USA. However, orfe can tolerate a higher level of salinity than any other cyprinid fish so may be able to colonise brackish water and estuarine habitats. These are often critical bottlenecks for anadromous (migrating up rivers from the sea to breed in fresh water) species. The potential for orfe to cause problems in countries where its natural controls are absent is of concern (David Rowe pers.comm., 2005).
Management Info
Preventative measures: The use of potentially invasive alien species for aquaculture and their accidental release/or escape can have negative impacts on native biodiversity and ecosystems. Hewitt et al, (2006) Alien Species in Aquaculture: Considerations for responsible use aims to first provide decision makers and managers with information on the existing international and regional regulations that address the use of alien species in aquaculture, either directly or indirectly; and three examples of national responses to this issue (Australia, New Zealand and Chile). The publication also provides recommendations for a ‘simple’ set of guidelines and principles for developing countries that can be applied at a regional or domestic level for the responsible management of Alien Species use in aquaculture development. These guidelines focus primarily on marine systems, however may equally be applied to freshwater.

Copp et al, (2005) Risk identification and assessment of non-native freshwater fishes presents a conceptual risk assessment approach for freshwater fish species that addresses the first two elements (hazard identification, hazard assessment) of the UK environmental risk strategy. The paper presents a few worked examples of assessments on species to facilitate discussion. The electronic Decision-support tools- Invasive-species identification tool kits that includes a freshwater and marine fish invasives scoring kit are made available on the Cefas (Centre for Environment, Fisheries & Aquaculture Science) page for free download (subject to Crown Copyright (2007-2008)).
