| Popis: | The ecological consequences of hatchery rearing have been widely studied, whereas there are relatively few investigations of the impact diets and culture conditions have on morphological variation, especially in rare or endangered species. The aim of the current study was to determine the impact of diet and culture conditions on the morphometric features of crucian carp (Carassius carassius), which is a species characterised by a highly variable body shape. In the first experiment, the impact of feed type on crucian carp's body shape was tested, while in the second, the impact of culture conditions on the body shape was determined. Feed type and culture conditions significantly impacted the shape and the morphology of crucian carp. Fish-fed larval chironomids exhibited the least variation in biometric characters, while those fed high-energy-formulated feed exhibited the greatest variation. In turn, individuals cultured in ponds exhibited greater variability in measurable characters than did fish cultured ... |
