Zoo Otter Welfare - Space and Behavioural Needs

Welfare requirements for otters in zoo settings, including territorial space, water quality, and feeding enrichment.

Key Facts

Eurasian otters occupy territories of 10-40 km of river bank in the wild; zoo enclosures cannot replicate this
Asian small-clawed otters adapt better to zoo environments due to smaller territories and higher social tolerance
Otters require clean, well-oxygenated water for swimming and hunting; water quality management is critical
Feeding enrichment using live fish, crustaceans, or frozen prey maintains foraging motivation and physical fitness
Otter scent-marking is a critical behavioral need requiring appropriate substrate and territory boundaries
