Effect of grading on energy consumption in European catfish Silurus glanis

Popis výsledku v původním jazyce

In aquaculture, fish grading is usually used to balance the resource availability for conspecifics in a stock. However, grading also leads to the interaction of individuals without any previous contact. Under laboratory conditions, we observed the spatial distribution of juvenile European catfish using passive integrated transponders while simultaneously measuring individual energy consumption using physiological sensors. We observed energy consumption during the interactions between familiar and unfamiliar conspecifics. Our results show that energy consumption during contact with familiar conspecifics was lower compared to energy consumption during contact with unfamiliar individuals. Furthermore, familiar conspecifics always took up positions closerto each other than did unfamiliar conspecifics. The presented results provide further evidence that the familiarity of stocked fish represents an important factor influencing the welfare of fish in aquaculture.
