Lethbridge Herald, The (Newspaper) - August 2, 1973, Lethbridge, Alberta 3O THE LETHBR1DGE HERALD August 1973 Fishing in alternate years in the southwestern Al- berta tributary is essential and the restriction must continue. This is the conclusion of a special report by Duane Rad- regional fishery biolo- gist at prepared recently. Mr. Radlorrt offers no hope ct meeting the recre- ational demands on the sport fisheries of given Following is the full text of the The present Alberta man- agement plan for east slope streams instituted in 1952. This program permits annual open fishing sea- sons on large whereas tributary streams are open only during alternate years. Previous to 1952 the provin- cial trout management poli- cies consisted stocking fingerlmg and yearling trout in streams believed to be perman- ent closure of unnamed minor tributary streams v.ithin the the that trout from the belief that tout from major streams migrated into such tributaries to thereby sustaining -wild trout populations in major closure of seasons during assumed spawning perioJs to cfford protection to mature and enforcement of a minimum size limit to allow trcut to spawn at least once before capture. the fallacies of these policies became known all subsequently being replaced in 1952 by the present regulators. For it was deter- mined that fingerling and yearling trout stocked in streams under all but ex- ceptional circumstances do r.ot provide a significant number of fish for anglers in most cases. the most abundant fish of east slope cutthroat are not mig- gratory and individually ap- pear to spend most of their life in a very small permanent clos- ure cf unnamed minor tribu- tary streams is not warrant- ed because cutthroat popula- tions in given streams are not migratory. By closing these streams fishing the populations of fish in major rivers are not en- and no harvest can be realized on the minor streams. Because spawning periouS of fish vary not only between different species but also and may be ex- tensive for certain it is unrealistic to attempt to protect fish by a blanket clos- ure of streams in large areas during spawning periods. This approach has consider- able merit in isolated especially when fish- are known to congregate. the state maturity therefore spawning con- of fish is not always related to their for ex- fish cf a given species may be mature at very dif- ferent sizes in streams locat- ed even in the same geo- graphical area. size limitations as a management tool are generally impractical except for specific cases and be very difficult to en- force if specified for all our streams. Our present management policy of opening tributary streams on alternate years is based on the premise that catchable-size cut- throat trout or more inches in caught dur- ing an open season are a product of previous closed seasons and reach a more de- sirable size or more inches in as a result of alternate closed a high percent of mature female cutthroat trout are harvested during an open thereby necessitating a subsequent closed season to ensure a minimum amount of natural the present season and delayed opening re- stricts most of the harvest of fish to the summer perioi angling pressure is hea- viest the daily catch limit of cutthroat trout is satisfactory. A creel census was con- ducted on Dutch Creek typical mountain stream in the Crow-Bow Forest open to fishing on alternate from June 1 Sept. 1972 to evaluate the effectiveness of our management program under present angling pres- sure. This pressure has increas- ed substantially since this program was initiated 20 years and about angling licences are sold an- nually in Alberta at this there are thousands of other anglers over the age of 55 and less than 16 years of that are not required to purchase licences and therefore cannot be tallied. The nature of the harvest on Dutch Creek in 1972 indi- cated that almost all catchable fish caught during the open season were a prod- uct of previous closed sea- a high percent of mature female cutthroat were harvested during the open the present season length 1 Oct. 31 of each fiscal year from April 1- March and re- cently delayed opening date in restricted most of the harvest to the period of greatest angling pressure and therefore satis- fied the most intensive recre- ational and the daily catch limit of cutthroat trout would have to be reduced DII Dutch Creek to four fish to effect even a pos- sible 20 percent reduction in the harvest. sort of re- duction would probably not save 20 percent of the trout but would likely only redis- tribute the total harvest among or permit it to be taken at later times dur- ing an open These results indicate that cur policy of opening tribu- tary streams to fishing on al- ternate years only still satis- fied the basic objectives of the management program. A departure from this system is not required and would in fact be undesirable. Anglers must realize that the productive capacity of our east slope streams is severe- ly limited by low annual stream temperatures and ex- tremes in two factors cannot be adjusted. Be- cause of these limitations only a finite number of fiSTi can reach a catchable size even under our present man- agement hatchery fish cannot be expected to add much to the catchable population of m o u n t a in sireams unless possibly all the wild fish are extermin- ated in the process. There- further restrictions in our programs may be neeu- ed to satisfy increasing de- mands on our sport Since an estimated angler trips occur in the Crowsnest Forest annually even now to 2.4 million for the the sngling pressure is too great to provide stream fish for everyone. For the number of anglers re- corded on Dutch Creek in 1972 was greater than the har- vest of fish there is considerable evidence to indi- cate that by the end of the season most of the catchable- size fish had been taken in this stream. a reduction in the limit from 10 to 4 cut- throat trout on Dutch Creek might be deemed necessary in the future to redistribute the harvest among anglers. If our native fish popula- tions are to be maintained in perpetuity is a goal of the fisheries section of the fish and wildlife the policy of opening tributary streams to angling on alter- nate years must remain un- changed. This policy will have con- siderable impact on the pos- sible establishment of perm- intensive recreational developments m the forest reserves. It will be unrealistic to al- ter our present management program to satisfy annual recreational demands on the sport fisheries of given streams. If this is attempted a serious decline in angling opportunities will follow.
