Data from: Effects of mate availability on egg production in the marsh ramshorn snail, <i>Planorbella trivolvis</i>, and ghost ramshorn snail, <i>Biomphalaria havanensis</i>
,Pulmonate snails are the first intermediate host in the life cycle of Bolbophorus damnificus, an important digenetic trematode in Mississippi catfish aquaculture. Two species, the marsh ramshorn snail Planorbella trivolvis and the ghost ramshorn snail Biomphalaria havanensis, commonly inhabit commercial catfish ponds in northwest Mississippi, USA. Low-level, repeated applications of copper sulfate have negative effects on snail reproduction and are effective in reducing snail populations in commercial catfish ponds, although they must be applied judiciously to minimize the phytotoxic and ichthyotoxic effects of copper. At present, little is known regarding population dynamics of these snails and underlying mechanisms driving their proliferation in catfish aquaculture ponds. This study investigated effects of mate availability on egg production in both snail species. Twelve individuals of each species were assigned to one of three treatments based on access to potential mates: continuously (“control”), weekly (“cyclic”), or at a single timepoint (“solitary”). Eggs were collected weekly, and the number of clutches, eggs, and non-viable eggs counted. The study ended at 21 weeks, one week after the final B. havanensis had died. More than 93,000 eggs were counted during the study, with over 60% from P. trivolvis.,

Data from: Evaluation of a snail trap prototype for monitoring the intermediate gastropod hosts of Bolbophorus spp. in commercial catfish ponds of the southeastern United States
공공데이터포털
,This dataset provides information on collection abundances of snails from commercial catfish ponds in the Mississippi Delta Region. Snail trap data were collected from weekly trap (passive) checks and monthly collections (active) from a commercial catfish production facility, Snail species include Planorbella trivolvis, Biomphalaria havanensis, and Physa sp. Data include weekly collections from traps (unknown trapping range) and monthly collections from 1 sq. meter sampling grids.,Resources in this dataset:,
Parasite Recruitment and Host Risk in a Snail-Trematode System at Carpinteria Salt Marsh
공공데이터포털
The project is located at Carpinteria Salt Marsh, part of the University of California Reserve System. The marsh is located at 34.40°N, 119.53°W, which is near the city of Carpinteria, CA. The "exp_recruitment" data set includes information on site name (site), latitude (lat) and longitude (long) of each site, cage number (cage), the number of egg-transmitted (egginf) and miracidium-transmitted (mirainf) trematode infections per cage, the biomass of snails within a cage (cagebmdens), and the influence (g^3/4) of final hosts that carry egg-transmitted (eggfhi) and miracidium-transmitted (mirafhi) trematodes. The "exp_risk" data set includes information on site name (site), latitude (lat) and longitude (long) of each site, cage number (cage), the length of each snail (length), the mass of each snail (mass), whether the snail was infected with an egg-transmitted trematode (egginf) or miracidium-transmitted trematode (mirainf), the biomass of snails within a cage (cagebmdens), the biomass of snails in the surrounding area (surrbmdens), and the influence (g^3/4) of final hosts that carry egg-transmitted (eggfhi) and miracidium-transmitted (mirafhi) trematodes. These data support the following publication entitled “Host density increases parasite recruitment but decreases host risk in a snail-trematode system” by J.C. Buck, R.F. Hechinger, A.C. Wood, T.E.
