Abstract: Objectives The objective of this research is to measure secondary production of New Zealand mud snail and native invertebrates in Polecat Creek. In addition we are surveying the Snake River to examine snail distribution there. Findings and Status We are in the middle of field sampling for mud snail secondary production. Preliminary data show that snail abundance and biomass is extremely high in Polecat Creek, with densities of about 400,000 / square meter during late summer. Abundance of native invertebrates is low. We found snails at low densities in the Snake River from Polecat Creek to the inlet to Jackson Lake. This upcoming summer we will survey the lake more completely.

| ABSTRACT | Objectives
The objective of this research is to measure secondary production of New Zealand mud snail and native invertebrates in Polecat Creek. In addition we are surveying the Snake River to examine snail distribution there.
Findings and Status
We are in the middle of field sampling for mud snail secondary production. Preliminary data show that snail abundance and biomass is extremely high in Polecat Creek, with densities of about 400,000 / square meter during late summer.
Abundance of native invertebrates is low.
We found snails at low densities in the Snake River from Polecat Creek to the inlet to Jackson Lake.
This upcoming summer we will survey the lake more completely. |
