Laser Ablation ICP-MS Otolith Microchemistry Analysis

The contract requires high-precision elemental and isotopic analysis of up to 400 salmon otoliths using laser ablation inductively coupled plasma mass spectrometry techniques, specifically LA-ICP-MS and MC-LA-ICP-MS, to determine the natal origin, migration timing, and whether individual fish originated from hatcheries or natural environments. The analysis will leverage microchemistry data extracted from otoliths to provide scientifically robust classification critical for fisheries management and conservation efforts. The work is scoped to deliver detailed spatial and temporal life history profiles for each sample, enabling differentiation between wild and reared salmon populations with high accuracy. This subcontract, posted under NAICS code 541380, is administered by the Department of the Interior through Sat Team 1 Fws, with a response deadline of August 10, 2026. The performance location and specific delivery details are not specified in the provided data, and no set-aside provisions or point of contact are listed. The solicitation is open for bids, and successful offerors must demonstrate capability in advanced geochemical analysis methods, sample handling protocols for biological microstructures, and experience interpreting isotopic signatures in aquatic vertebrates to meet the technical objectives of the project.
