KRIS E. Marin Sonoma: Meta Information Page
This page contains detailed information about a data set in KRIS, including where the original data reside and how to contact the sources for the data. Data sets are linked to the appropriate page by means of the Meta Identifier. Many data sets can be linked to same page by sharing the same Meta Identifier.
Meta Identifier Simpson_Fish Type of Data Fish Dive Survey Originator Nick Simpson Description Fish dive surveys were conducted in Miller Creek on August 2, August 5, August 8, 2002 as part of a fish behavior study conducted by student project by Humboldt State University student Nick Simpson for the San Jose Flyfishing club. The data also included maps of each surveyed pool, indicating where fish of each species were observed in relation to pool depth. However, formatting difficulties may have compromised the accuracy of the maps, so they could not be included in KRIS. At the time the data were contributed to KRIS, his final report was not completed and so could not be included in KRIS. Additional data were collected in summer 2003 that is not included in KRIS.

Data Quality Information The survey found juvenile Chinook salmon, which was previously unknown to inhabit Miller Creek. That finding was not documented with photographic or other verifiable evidence, so the possibility of misidentification cannot ruled out. Use Constraints See data quality information Keywords fish, snorkel, behavoir Abstract Abstract: I examined behavioral interactions between five species of fish, Steelhead trout ( Oncorhynchus mykiss)(Age class 0+, 1+, 2+/resident), Chinook salmon (Oncorhynchus tshawystscha), California Roach (Hesperoleucus venustus), Threespine stickleback (Gasterosteus acculeatus), and Sacramento Sucker ( Catasotumus occidentalis )(Greater than 11cm and less than 10cm), to discover patterns in spatial distributions between species and depths within pools in late summer. Similar habitat was found to be utilized by certain species, as well as distributions among species. Interspecific interactions could be primarily seen within the steelhead and California roach, where steelhead were found taking refuge in schools of California roach, in both tailouts and heads of pools, 30 -60 cm deep. Intraspecifically, threespine stickle back and <10cm Sacramento suckers resided among only themselves in average depths of 5 -10 cms, as did the Chinook, in deeper pools. 2+ steelhead and Sacramento sucker greater than 11cm, although few in number, were found in the deepest pools and also behaved intraspecifcally within their own size classes.
