Introduction:

Crucian carp (Carassius carassius) (Linnaeus, 1758) the most freshwater fish that inhabits in every place of Japan, China and most of Europe including Russia (Copp & Sayer, 2010). The Crucian Carp is the smallest of the Carp family It is easily distinguished from a small common carpby the absence of barbels. They live in lakes or stagnant areas of rivers.This fish small head and mouth and an up-turned lower lip. It tends to be rusty-bronze in color with a gold-orange colored belly (Jasim,2009). Basic cyprinid characteristics include no teeth on the jaws, a single dorsal fin, pelvic fins in an abdominal position, pectoral fins low on the side, and no adipose fin. (Aydin, et al., 2011 & Pamela, et al., 2006). Crucian carp can grow 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 hardy fish: 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 and covered 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).

Crucian carp in Turkey:

C. carassius is native to Turkey. Species of the genus Carassius were transported to numerous inland water bodies throughout Turkey perhaps because of the physical similarity 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, altered waters, park and garden ponds in various parts of Turkey. (Innal,2011). Introduction of fish species in Turkey, like elsewhere in the world, has had both positive and negative implications. But the impact of most introductions of fishes is still unknown. Abundance and distribution of Carassius species in Turkey continuous to increase steadily, and are now considered a threat factor for native fish species.

Crucian carp in Iraq:

C. carassius is one of the scavengers fish. It can eat anything in the aquatic body like brushwood. This fish maturate in less than one year while other local fish maturation extend four years like shabout & Gattan or two year like Bunni. (Radi, 2012). Inhabit and sweeping of environment affecting on the growth and life of original fishes. Because all local Iraqi fish don't tolerate turbidity because this type is bottom-feeder besides the ability of crucian to reproduce with other cyprinids type making sterile individuals in some cases (Fahd, 2012). So, it is important to obtain the balanced between this fish and other original fishes by controlling the release of this fish from Turkish dams and other aquatic bodies in order not to invade these bodies by foreign type with decreasing the main fish types.(Mohamed et al., 2006).

This fish consider chieftain of Tigris & Euphrates fishes.

The Crucian carp was introduced to Iraq by unintentional release from Turkish dams throw 2005.

Tolerant and hardy fish that thrive in a wide variety of aquatic habitats.

Strongly compete with the young of most cyprinid fish species for food and space.

Crucian carp is known as one of the most hazardous fish species for native fish communities.

Currently the largest (3/4 of all fish production is crucian carp).

It appears to occupy an unexpected ecological niche or even lead to unexpected changes in the behavior of native species.

Predate heavily on phytoplankton and zooplankton.

Appear to be a serious competitor of native fish species.

Population density of the Carassius species have increased rapidly in the inland waters of Turkey & Iraq , and now it is the dominant fish species of some aquatic systems.
