WHAT CAN BE DONE TO HELP?You can do many things to help.• Foremost, you can remember that theaquaculture industry is driven by consumerdemand, and that customer choices, count.The less demand, the less production, andless marketing in stores and restaurants;• You can stop buying and eating farmedsalmon;• You can tell others why you won’t buy or eatfarmed salmon;• You can ask whether unidentified fish—instores and restaurants—are wild or farmed,and;• You can write to your Federal Member ofParliament or Provincial Member of theLegislative Assembly, the Provincial Minister ofAgriculture, Food and Fisheries, or the FederalMinister of Fisheries explaining that thesalmon farming industry should not be permittedto operate in BC unless it is run in a sustainablemanner, and unless it poses no threatto wild salmon.• Find your Federal Member of Parliament hereor check your local library:www.canada.gc.ca/directories/direct_e.html• Find your Provincial Member of the LegislativeAssembly here or check your local library:www.legis.gov.bc.ca/mla/3-1-1.htm• To contact the Hon.

Why conserve the diversity of wild salmon?Conservationists frequently extol the importanceof conserving biodiversity—butrarely explain why. Most of the argumentshave to do with ethics (it is the right thing todo). Only recently, however, have we begununderstanding the biological merits of biodiversity.A study of Alaskan sockeye sheds newlight on how “biocomplexity” (or biodiversity)in salmon helps generate sustainability. (1)Sockeye have colonized numerous rivers in BristolBay, and over time, these populations have developeda ‘suite of adaptations to the diversity of spawningand incubation environments’. In certain years, environmentalconditions appear to favor some populationsover others. Rivers that were once productivehave declined, while others that were once small producersare now major ones. In a broad sense (thescale of Bristol Bay, at least), the resilience of salmonis linked to the maintenance of “all the diverse life historyand geographic locations that comprise thestock.” The biocomplexity now recognized as being soimportant could easily have been lost, had earliermanagers focused too much on the then most productiveruns, and neglected the less productive ones. (1)Conservation biologists have recently said that byconserving biodiversity we are in fact conservingimportant “redundancies” and “reinforcement of function”.(2) In this case, redundancy is not used in theway an engineer might explain how to achieve engineeringreliability, but rather, how each species (orpopulation, or stock) has a “similar scale of function”through “different responses to unanticipated environmentalchange.” Put another way, this ‘within-scaleand between-scale diversity’ produces an overlappingreinforcement of function that is remarkably robust. (2)The importance of overlapping reinforcement of functionis shown in the simple example of roofing shingles.(2) We can also liken wild salmon to the cast of an“ecosystem theater” in which certain populationsserve as “stand-in actors” waiting in the wings toreplace regular performers who fall. (2) Without suchstand-ins, a loss of function might cascade across abroader geographic area, thus reducing the continuous(sustainable) supply of salmon for catching, forcultural and social needs, for biological perpetuation(through both natal stream spawning, and strayingand replacement of lost stocks), and for supplyingcritical marine-derived nutrients to terrestrial habitats.This overlapping function has been termed “imbricated(overlapping) redundancy”. (2) In the case ofsalmon, the greater the number of locally adaptedsalmon populations in a given area, the greater theoverlap in function, and the more likely that wildsalmon will collectively persist and adapt in the faceof changing environmental conditions. Thus, anythreats to local populations of wild salmon—includingthose posed by open net-cage salmon farming—havecoastwide implications to the adaptability, productivityand persistence of wild salmon.(1) Hilborn, R.
