| Popis: | Passive integrated transponder (PIT) technology allows passive, individual identification of small fish, making it a potentially useful tool to address an information gap of juvenile salmon habitat use in off-channel environments. We investigated the combined use of field enclosures and PIT technology as a method for studying the habitat preference of juvenile Chinook Salmon Oncorhynchus tshawytscha on a flooded rice field, a potential surrogate for lost floodplain habitat. We stocked two field enclosures (182 m2) with 42 juvenile salmon. One enclosure had equal portions of rice stubble, disced, and fallow habitat treatments, and the second contained only the disced treatment. Fish were tagged with 8- or 12-mm-sized PIT tags, and generated approximately 1 million detections in each enclosure over 14 d. We used a condensing procedure to reduce the data volume while preserving habitat use patterns. The smaller 8-mm tags were only detected along antenna edges, and the 12-mm tags had broader but more ... |
