Dear FISH-ECOLOGY Members,
I am seeking your help in identifying any documentation of ecological
effects of introduced salmonines in the North American Great Lakes, with a
particular emphasis on the following species:
- Atlantic salmon (Salmo salar); in the upper lakes
- brown trout (Salmo trutta)
- chinook salmon (Oncorhynchus tshawytscha)
- rainbow trout (Oncorhynchus mykiss)
- coho salmon (Oncorhynchus kisutch)
- kokanee (Oncorhynchus nerka)
- pink salmon (Oncorhynchus gorbuscha)
I have worked my way through much of the primary literature on this topic,
however it is clear that many ecological effects of non-native Great Lakes
salmonines have been reported in an anecdotal manner or as side issues in
a larger context. Moreover, it appears that much of the work on
ecological effects was written up in the format of technical reports,
rather than being published in the primary literature.
For convenience, I have generally followed Li & Moyle (1981) in
classifying the potential ecological effects:
1. Effects of introduction on the introduced species
1a. Survival
1b. Growth and development
1c. Dispersion and migration
1d. Reproduction
1e. Life-history alteration
2. Effects of introduction on the receiving ecosystem
2a. Diseases and parasites
2b. Predation
2c. Competition
2d. Genetic effects (direct and indirect)
2e. Environmental alteration
2f. Community alteration
NOTE: Please forward any references to relevant primary or technical
literature directly to me at [log in to unmask]
After compiling all of the responses I will notify the FISH-ECOLOGY
members, and I will send a copy of the resulting bibliography to those who
request it.
Thank you in advance for your assistance.
Sincerely,
