82 REPORT OF THE COMMISSIONER OF FISHERIES. 



tiro 75 foct loii^, (■> fc'ct Avido, witli uii avora^e depth of 'M) inches, 

 and liave an estimated rapacity of r)0,()()() sookeyo fin«rerlin<:^s. Shortly 

 after Septeinher 15, traps Avere ])hiced in tlie rack at Binr Crock, and 

 the e(jiiipincnt was made ready for the spawninuj season, which 

 opened October 1. Tlie sockeye salmon conntcd thron^di the trap 

 at the end of June, li)t22, niimliei-ed 1!M),IS{), in addition to 42J) steel- 

 heads and 1251 l)lacksi)ottcd trout. It is estimated that the run was 

 ecpial to the hi^; nni of l!>ir). Many of the Indians secuird excellent 

 catches of salmon, some takino- j,s many as -'500 fish per day with dip 

 nets, and a profit of fi-om $!>()() to $;U)() per day for the «;ill-netters 

 was not nnnsual. A price of 50 cents per fish, re<2:ardless of size, was 

 paid by the packers throu^diont the season. Of the salmon counted 

 at the weir S.S per cent had received ^ill-net markin^rs at the mouth 

 of the rivei-. 



l<'ish-cuHui-al operations \v(M-e con(hicted as usual in the California 

 fl(dd, and at Haird and its two auxiliai'i(>s an axcra^'e numb(>r of fry 

 was held and fed to the fin<j;erlin<!; sta<j;e. The total number of 

 clunook-salmon e<2:<rs colkM-ted amounted to (),,'55;i,00(). All of these 

 stations are in need of extensi\e I'earinjj; jionds and a more ade(]uate 

 water supply. 



The usual oix*: collections were mmh at the stations in ()re«f<)n, 

 althoujih a rise in the Clackamas Kiver ended the season suddenly 

 at Clackamas staticni on October 'JS, Avhen a portion of the rack was 

 can-ied away, allo\vin<!; lar<j;e numbers of chinook and silver salmon 

 to pass upstream. Both runs of <'hinook salmon were etiual to ex- 

 |)ectations thr()u<!:hoiit tlie field excei)t on the Ko^ue Kiver and in 

 Idaho, the take of eivfis at these points bein<]f materially lessened by 

 hi^h Avater durin<i; the late sjn-ini; Avhen the snoAv Avas meltin<i:. At 

 (Mackanuis and its anxiliaries ()-'V()S5,0()0 ejrf^s were collected, of which 

 5T,SS5.00() weiv chinook salmon. Salmon fry to the number of 

 5 1,M (),()()() were retained at the various i)oints to he fed, but it Avas 

 I'ound later- that this heavy stock Avas o\(M'ta\in<j: the caj^acity of the 

 hatcheries, and the sur))bis had to be released. Tt is very essential 

 that increased holdin<r si)ace be provided in advance of another 

 season's operations so that all salmon ])ro(lnced may be held and fed 

 for liberation at a more advantai^eous ])eriod. The fish held ap- 

 ])eared to thrive and showed no ill effects from a diet of middlinp:s 

 mixed with meat. Tt has been found that by feedin<r the lish sloAvly 

 tAvice a day the i-esults ar(> better than if fed from fonr to six times 

 daily. Tn liberatinir the fish from the sloughs and other inclosui'es 

 experience has shoAvn that it is ])referable to release them in small 

 lots.

Collections of (><2;<rs at the marine stations exceeded those of 1921 by 

 approximately ;U)0,000,0()0, but the outi)nt Avas materially less than iii 

 the precedin<; year, owinjx to the adverse conditions under Avhich the 

 eiTjrs Avere obtained and tlieir resultant inferior (luality. On acconntof 

 the shorta<;e in funds s|)awn takers could not be placed on the vessels 

 of the ofVshoi-e fishermen to fertilize and ])lant the ripe spawn taken.

 jl^ation of the winter flounder, of Avhich the output amounted to 922,-
