Carp dominate crayfish in invasive species battleground
Date:3/6/2012

the signal reflects diet over space and time, our approach offers an appropriate scale for the study of population niches, the 'space' that a species occupies in a food web.

"Carp and crayfish eat the same types of food from the lake bed if they are not in conflict however with the carp's population increase the crayfish were forced to eat a lower quality diet, including hippo dung.

"The dietary niche of the crayfish has been squeezed to such an extent that it is now almost impossible to catch crayfish in the Lake anymore."

Lake Naivasha is extremely important to the local community and the wider economy of Kenya because of its large volume of freshwater both for drinking and floriculture, and the commercial fishery industry. Yet it has been the subject of a catalogue of ecological errors from species introductions over the last 100 years which affect its ability to provide ecosystem goods and services.

"The Lake provides such an important resource for the local community. We know that the influx of carp has helped commercial fishing in the area but with its continual dominance we don't know to what extent it will affect the lake's water quality and the wider ecosystem on which the thriving floriculture and agriculture industries rely," Dr Grey said.
