The accuracy of five different methods used in spraint analysis for extimating prey proportions is tested through a feeding experiment with three otters in captivity. Estimated prey proportions are copared to the actual diet of the otters.
Otter spraint analysis Moors for the Future have a new Community Science Project, looking for signs of mammals in the uplands, the Tails of the Uplands Survey. (Follow the link for details of how to get involved and training courses available.).
Otters have an acute sense of smell, hearing and eyesight. Its eyes are placed at the top of the head, so it can remain alert whilst the rest of the body is underwater. They communicate via whistles, twittering noises and spitting sounds, which can be heard at night when it is quiet and still.Stanza 1 Analysis: This woman is the cause rather than effect. She's in control in this place of romance. Her swimming is beyond rhythm and beauty. Stanza 7: And suddenly you're out, Back again, intent as ever, Heavy and frisky in your freshened pelt, Printing the stones. Stanza.Spraint analysis accurately determined the rank order of prey groups for individual otters and for all four combined. However, few of the true proportions consumed fell within the 95% confidence limits calculated from spraints.
In the case of two cryptic, co-occurring South African otter species, namely the Cape Clawless otter (Aonyx capensis) and the spotted necked otter (Lutra maculicollis), faeces (spraint) is used as a means of determining presence, space use and diet (Arden-Clarke, 1986, Van Niekerk et al., 1998, Perrin and Carugati, 2000, Angelici et al., 2005). However, due to similar diets the spraint can.Read More
The diet of otters Lutra lutra was studied by spraint analysis in six river and stream habitats in eastern Poland. In all of them fish were the staple food of otters, constituting from 29 % to 96.Read More

Otters also have an acute sense of smell! 6: NEVER BAIT AREAS OR OTTERS. Doing so may change otter behaviour patterns and will be VERY detrimental to the species. 7: Never remove spraints (dung). These are very important, as they are used to communicate with other otters. 8: Stay aware. Please remain aware of how the otter is behaving.Read More

ECOLOGY AND CONSERVATION OF OTTERS (LUTRA LUTRA) IN LOCH LOMOND AND THE TROSSACHS NATIONAL PARK. methods of diet analysis show that the most frequently occurring prey in spraints was the ruffe but there were small differences in the rank abundance of cyprinids and eel (Fig. 2).

Knowledge of the effect of habitat type and region on diet and feeding behaviours of a species facilitates a better understanding of factors impacting populations, which contributes to effective conservation management. Using spraint analysis and relative frequency of occurrence data from the literature, we described the dietary patterns of Eurasian otters (Lutra lutra) in 23 study sites.Read More
Direct monitoring methods include camera trapping and radio-tracking; indirect monitoring methods include track surveys, spraint surveys and molecular scatology (genetic analysis of spraint material). Spraint and track survey have been used since the 1970s in National Surveys to assess the rate of otter recovery. However, while most of these methods can contribute information on population.Read More
