> 



Popular account of the natural history of the smelt — 

 habitat, spawning, growth, food, predators ,•• • — , its introduction

 as a food and sport fish and as a competitor with and predator 

 on native species. 



19hl, The age and growth of fresh- water fishes, A Symposium 

 on Hydrobiology, Univ. of Wis. Press, pp, 196-20^, 



An appeal for further and more discriminating research into 

 fundamental aspects of the scale method, a review of recent develop- 

 ments in the use of scale measurements for the calculation of cast 

 growth, and an outline of the numerous applications of age-and- 

 growth studies in conservation and fish management and in taxonomic 

 investigations .
