200753900 - Promote Kokanee Repopulation in Lake Pend Orielle using Autonomous Underwater Vehicles (AUVs) for Location and Verification of Lake Trout Spawning Areas.
Sponsor: University of Idaho - Microelectronics Research & Communications Institute (MRCI)
Short description: The proposed work will apply underwater robotics technology to allow researchers to visually survey large areas of the floor of Lake Pend Orielle to locate and verify Lake Trout spawning areas.
Location: Intermountain province, Pend Oreille subbasin
Budgets: FY08: $363,476 | FY09: $36,701
Primary species:
Resident: Kokanee
Resident: Bull Trout
Objectives
| Objective | Description | Subbasin plan | Strategies |
| 01. Bull trout/Cutthroat trout Preservation. | In Lake Pend Oreille reduce competition and predation by lake trout on bull and cutthroat trout by reducing lake trout abundance to < 4,000 adults, if feasible. | Intermountain | Strategy a: ... if lake trout abundance or population structure is resulting in unacceptable predation (it is)... research methods to reduce the energetic demand or competitive impact of the lake trout population. |
| 02. Restore kokanee abundance | By 2020 restore kokanee populations in Lake Pend Oreille to allow sustainable harvest of 750,000 fish/year, as long as this activity does not adversely impact native fish. | Intermountain | Strategy c. Develop methods to monitor predator abundance and balance predator and kokanee populations. |
| 03. Predator/prey balance | By 2010 balance predator (lake trout, rainbow trout, bull trout)/prey (kokanee) populations in Lake Pend Oreille (1:10 biomass ratio). | Intermountain | Develop... active predator reduction methods to restore predator:prey balance if needed. |
