With regards to the Giant Otters for Chester . I have just been looking at the 2004 Giant Otter Studook and Husbandry manual ( on the San Diego Library website , found via Studbooks thread ) .
This very long - 270 + pages - document goes into great detail on husbandy necessities for the species . The 3 critical elements of an enclosure for successful husbandry are
- the correct land: water ration , seems about 60% land in an average enclosure, a formula is given for calculation
- provision of a soft , dry , loose natural substrate for the land area is essential for grooming and digging in
- provision of deep digging areas within the enclosure
I am sure the team at Chester have studied this document . It does seem that the Sea Lion enclosure as it now stands is nothing like how an Giant Otter enclosure should be set up , so hope we will see a lot of work on it .
I also picked up from a quick skim through some of the document that the previous pair of Giant Otters at the Chestnut Centre were fed live rainbow trout . As has been mentioned elsewhere I did not think this was allowed in the UK . Also the enclosure at the Chestnut Centre was judged to meet husbandry standards .
Encouraging to see how the species captive situation has improved in the last few years , then very few were being bred with most animals very closely related .
