Box 1269 <br />Highway 550 South <br />Montrose, Colorado 81401 <br />Bob Rosette <br />Southwest Regional Director <br />Division of Wildlife <br />1800 Highway 550 South <br />Montrose, Colorado 81,401 <br />Dear Mr. Rosette: <br />IN ItesLY ■pick rD . •. <br />6670 . <br />(130) <br />The enclosed data is being submitted by our District Fisheries Biologist <br />(Jeff Cameron) for your information concerning electroshocking results <br />on the District during the FY8O field season. Due to the workload <br />this summer, we only had time to effectively shock one stream (Rock <br />Creek in the Gunnison Resource Area), but wer <br />o.'spat check" k a <br />couple others in the West End (Tabeguache and aSal eeks). E1�ct�o- <br />shocking is very much a part of the aquatic inventory process here on <br />the District and we are pleased to be able to cooperate with ydur <br />agency in this exchange of information. We plan to continue these <br />efforts in the future and hope to obtain more of this type information <br />on the ,District's fishery. <br />Also enclosed is Jeff's application for a 1981 Scientific Collecting <br />Permit and the required fee of $10.130. <br />Salmonids were the only fish species found in Rock Creek, The adults <br />were identified as brook trout but no positive identification on <br />juveniles was obtained (see attached data sheet). The Sebor- laCren <br />two pass method is being used for population estimates. However, in <br />the case of Rock Creek, there may not have been a large enough differ- <br />ence in, total numbers between Catcand Catch2 to give valid results. <br />This system will be worked with and refined in the future since we <br />usually leave much of the data analysis until after the field season. <br />Rough estimates indicate that there are approximately 120 lbs /acre of <br />fish in this stream. However, as evidenced by the data sheet, we may <br />want to get together and take a closer look at the age distribution. <br />Last year Jeff observed a good number of large (greater than 10 <br />inches) brook trout but the larger fish appeared to be lacking in <br />this year's sample. We plan to keep working with Rock Creek since it <br />will be used as a °demonstration•stream" for exclosure work, habitat <br />coNeemve <br />AMERICA'S <br />Eh1Y <br />Save Energy and You Serve America! <br />• <br />
