introduction
Introduction
  • Mussels clean rivers and streams
  • Indicate health of river system
  • Round Pigtoe threatened in MN, native to St. Croix

Introduction

Glochidia with and without tissue

Previous studies show there may be a difference

previous studies
Previous Studies
  • Spotfin shiner, common shiner and hornyhead chub are host fish
  • Golden shiner and creek chub are marginal host fish
    • From 2003 Host Fish Suitability Trial
previous studies6
Previous Studies
  • 2003 Study, glochidia without and with tissue as life cycle stages
goals
Goals
  • Find which host fish is statistically stronger: hornyhead chub or common shiner
  • Find new host fish
  • Study glochidia without tissue and with tissue as life cycle stages
procedure
Procedure
  • Collect host fish and mussels from St. Croix River
  • Infest fish with glochidia and check siphonate every three days
  • Fish in statistical study kept in individual aquaria
results
Results

Table 1: Percent Transformation for hornyhead chub and spotfin shiner

conclusions
Conclusions
  • Common shiner, mimic shiner, blackchin shiner and longnose dace are host fish
  • Not able to determine difference between glochidia without tissue and with tissue
  • It appears that related fish host the same mussel
practical applications
Practical Applications
  • Results of the statistically stronger host fish could be used to reintroduce the Round Pigtoe mussel by making raising mussels in a laboratory setting more efficient
  • By finding that related fish host the same mussel, host suitability trials can be simplified
future studies
Future Studies
  • Repeat the study with many species of fish from the same family
  • Conduct a Histological study with pictures of mussels at different life cycle stages to deterimine if glochidia without and with tissue are separate life cyce stages
