The additional volume needed mula: 4 X average adult le (space) required for up to two Group I of the longest speci cetaceans is based upon the following cetacean formula: 2 x 3.14 x depth (12 body length or 5 feet, whichever is greater), or: TA Dividing this figure by 4 would give the volume required for each individual Group II cetacean of a specified average adult length. This is the figure which is to be used for each additional Group II cetacean when more than four are to kept in a pool and more space is required. See Table II for required volumes. (iii) When a mixture of both Group I and Group II cetaceans are housed together, the MHD must be satisfied as stated in g 3.104(b)(1), and the minimum depth must be satisfied as stated in $ 3.104(b)(2). Based on these fig. ures, the resulting volume must then be calculated In a pool containing more than two Group I cetaceans or more than four Group II cetaceans, & the additional surface area which may be required when animals are added must be calculated for each such animal. (ii) When a mixture of Group I and Group II cetaceans are to be housed in a pool, the required MHD, depth, and volume must be met. Then the required surface area must be deter : mined for each animal in the pool . The sum of these surface areas must then be compared to the surface area which is obtained by a computation based on the required MHD of the pool.' The larger of the two figures represents the surface area which is required for a pool housing a mixture of Group I and Group II cetaceans .

If this volume is greater than that obtained by using the MHD and depth figures, then the additional volume required may be added by enlarging the pool in its lateral dimensions or by increasing its depth, or both. The minimum surface area requirements discussed next must also be satisfied.
