The apparatus 1 of the present invention serves to stun animals prior to slaughter, these being introduced with a gondola 3 into a pit 2. On a sidewall 5 of the pit is/are designed a gas module 7, preferably a plurality of gas modules 7. Each gas module 7 comprises a gas introduction line 8 having a multitude of pores 10 through which an anaesthetic gas can flow laterally into the pit 2. The multitude of pores 10 ensures a laminar inflow of the anaesthetic gas. The lateral laminar inflow of the anaesthetic gas avoids an increase in the stress of the animals being stunned, thus enabling humane stunning prior to slaughter. At the same time, the modular construction by means of the gas modules 7 facilitates simple dimensioning of the gas intro¬ duction capacities required and also the construction and retrofitting of corresponding apparatuses 1.
