  2. 2. Introduction:Crucian carp (Carassius carassius) (Linnaeus, 1758) the mostfreshwater fish that inhabits in every place of Japan, China and most ofEurope including Russia (Copp & Sayer, 2010). The Crucian Carp is thesmallest of the Carp family It is easily distinguished from a small commoncarp by the absence of barbels. They live in lakes or stagnant areas ofrivers. This fish small head and mouth and an up-turned lower lip. It tends tobe rusty-bronze in color with a gold-orange colored belly (Jasim,2009). Basiccyprinid characteristics include no teeth on the jaws, a single dorsal fin,pelvic fins in an abdominal position, pectoral fins low on the side, and noadipose fin. (Aydin, et al., 2011 & Pamela, et al., 2006). Crucian carp cangrow to about (20-30) cm maximum length, they can live up to 10 years,although older-living individuals have been known (Taran, et al., 2000).Crucian carp prefer small, nutrient-rich ponds and lakes. They are very hardyfish: has an amazing ability to survive for months with almost no oxygen.This is an adaption to allow survival in ponds that are frozen over andcovered with snow - survive water temperatures up to (38oC) (Yilmaz, et al.,2004). and can live in acidic waters where the pH can be as low as 4.Crucian carp are also very tolerant of pollution, especially organic types(Radi,2012). 2

  10. 10. Crucian carp in Turkey:C. carassius is native to Turkey. Species of the genusCarassius were transported to numerous inland waterbodies throughout Turkey perhaps because of the physicalsimilarity of the species to the native common carp(Cyprinus carpio Linnaeus, 1758). As a result of mis-identification, the expansion of species were not noticed.These species are now common in natural habitats, alteredwaters, park and garden ponds in various parts of Turkey.(Innal,2011) Introduction of fish species in Turkey, likeelsewhere in the world, has had both positive and negativeimplications. But the impact of most introductions of fishes isstill unknown. Abundance and distribution of Carassiusspecies in Turkey continuous to increase steadily, and arenow considered a threat factor for native fish species.10

  14. 14. Crucian carp in Iraq:C. carassius is one of the scavengers fish. It can eatanything in the aquatic body like brushwood. This fishmaturate in less than one year while other local fishmaturation extend four years like shabout & Gattan or twoyear like Bunni. (Radi, 2012). Inhabit and sweeping ofenvironment affecting on the growth and life of original fishes.Because all local Iraqi fish dont tolerate turbidity because thistype is bottom-feeder besides the ability of crucian toreproduce with other cyprinids type making sterileindividuals in some cases (Fahd, 2012). So, it is important toobtain the balanced between this fish and other original fishesby controlling the release of this fish from Turkish dams andother aquatic bodies in order not to invade these bodies byforeign type with decreasing the main fish types.(Mohamed etal., 2006). 14

  20. 20. 1. This fish consider chieftain of Tigris & Euphrates fishes.2. The Crucian carp was introduced to Iraq by unintentional releasefrom Turkish dams throw 2005.3. Tolerant and hardy fish that thrive in a wide variety of aquatichabitats.4. Strongly compete with the young of most cyprinid fish species forfood and space.5. Crucian carp is known as one of the most hazardous fish speciesfor native fish communities.6. Currently the largest (3/4 of all fish production is crucian carp).7. It appears to occupy an unexpected ecological niche or even leadto unexpected changes in the behavior of native species.8. Predate heavily on phytoplankton and zooplankton.9. Appear to be a serious competitor of native fish species.10. Population density of the Carassius species have increasedrapidly in the inland waters of Turkey & Iraq , and now it is thedominant fish species of some aquatic systems.20Conclusions:
