Becker, George C. / Fishes of Wisconsin
Preface, pp. ix-x PDF (623.3 KB)
x Preface only in Wisconsin but throughout their ranges. The accounts for these species are often fragmentary, and they point up the need for careful investigation to ensure the continued existence of such species. As I prepared the distribution maps, it became evident that an irretrievable loss had occurred in the fish resource. Some species were extirpated. The spe- cies composition of Lake Michigan had changed radically within a few decades: in some basins several species had been completely eliminated, and exotic fishes had established successful populations, especially in waters undergoing exten- sive man-related changes. The fish complex was changing rapidly in parts of the state-much too rapidly to predict a secure future for some species. My concern resulted in the preparation of introductory sections of text dealing with the water resource as it affects the fishes; past and present changes in water quality and anticipated effects if present demands for water continue; our early handling of the fishery resource, the manipulation of the fishery resource today, and the future values of fishes. I have suggested changes in management which may help to restore an ailing fish resource. Remedial action may be costly to implement, but this cost will be insignificant compared with the cost to our children who must mourn the missing pieces and who must struggle to reas- semble the ecological disruptions we leave behind. My taxonomic keys have been tested in a number of fish laboratories, and criticisms and suggestions have been honored in the latest revisions. But be- cause fish did not evolve into species all fitting neatly into the slots provided within an artificial key, the key may break down unexpectedly. I would appre- ciate hearing from readers regarding problems with the keys. I am also aware that in the life history accounts new knowledge will replace or modify old knowledge. It is difficult to keep abreast of all publications, bits of unpublished research, and isolated but important pieces of information. I therefore welcome such information and encourage you to write to me at the Department of Biology, University of Wisconsin-Stevens Point. Your sugges- tions will ensure a better future edition.
