One time, when I went to camp at SeaWorld in San Antonio, Texas, I went into the lake where the ski stadium is located with my camp group to collected some freshwater fish that would help feed the small-clawed otters in their exhibit. As a group, we would round the fish up by walking behind them before putting a net in the water to catch them. The fish, which are taken alive from the lake, are then taken into the animal care department before they are placed into the otter exhibit to serve as both food and enrichment to the otters. This is because in the wild, hunt food by using their vibrissae to detect movements of prey in the water. They use their forepaws to locate and capture items rather than their mouth. To recreate that behavior, animal care staff at SeaWorld San Antonio acutally catches fish from lake where the ski stadium is located and bring the live fish to animal care where they are prepared to be brought to otter exhibit. For the otters on exhibit, the live fish in their exhibit is not only a form of a feeding session performed by their caretakers, but, it is also an enrichment session for them too. However, if a trainer is training them, it’s a good idea to start with a large enrichment item first because then, they would be much more responsive to training afterwards.
