Paired Scale Sample Feasibility Analysis

The contract seeks to evaluate up to 200 paired scale samples to determine the feasibility of distinguishing juvenile rearing locations through scale analysis, with the goal of correlating these findings with existing otolith data. This effort aims to assess whether scale patterns can reliably serve as a substitute or complement to otolith microchemistry for identifying the natal or early life habitats of fish, which has implications for fisheries management and ecosystem monitoring. The work will involve laboratory analysis, data comparison, and interpretation to establish methodological validity and practical applicability in real-world scenarios. The solicitation is categorized as a subcontract under NAICS code 541620, indicating scientific and technical consulting services, and is issued by Sat Team 1 Fws within the Department of the Interior. The opportunity was posted on July 30, 2026, with a response deadline of August 10, 2026. While no specific location for performance or point of contact is provided, the work is tied to federal natural resource management objectives. No set-aside designations are specified, and interested parties must submit proposals before the deadline to be considered for award.
