Boggy or wet areas, ponds, ditches and streams are all potential habitats for the mud snail
and thus risk areas.
Chemical mediation of egg capsule deposition by mud snails
Fourteen species and higher taxa of trematodes were reported from native populations of the New Zealand mud snail
(Macfarlane 1939, Winterbourn 1973, MacArthur & Featherston 1976, Jokela & Lively 1995, Dybdahl & Lively 1998).
The study group later conducted a reproduction test with the New Zealand mud snail
to determine the source and potency of the xenoestrogens.
Odorant solutions prepared from horseshoe crab eggs, and molecular weight fractions of these, were tested because they have been reported to be attractive to mud snails
(Ilyanassa obsoleta), and because horseshoe crab eggs have been proposed as a source of compounds for inclusion in manufactured bait (Ferrari and Targett, 2003).
New Zealand mud snails
(shown here on top of a dime) have been found in Tim Alpers' trout farm, forcing his fish to be banned from most Eastern Sierra waters.
We discovered previously that the mud snail
(Ilyanassa obsoleta) biotransforms and retains excess testosterone primarily as fatty acid esters.
In these areas populations of the native mud snail
, Cerithidea californica, have declined precipitously.
Resistance issues will also be highlighted along with the fourpoint plan for fluke control, which includes pasture protection in the spring and reducing the mud snail
population in summer, as snails are an intermediate host for liver fluke.
Capitol Lake New Zealand mud snail
response: benthic macroinvertebrates study results.
The New Zealand mud snail
, equally prolific, already has arrived in Oregon, having hitched a ride from the islands, most likely with anglers.
The mud snail
called lymnaea truncatula, is found in boggy areas with neutral or alkaline soil conditions.
