# Agriculture Daily Summary: What Happened on October 29, 2026

**A refined qPCR test adds a control for sturgeon sexing**

Lake Superior State University's research center has tested hundreds of fish samples with the assay, which may also help interpret results when sample quality is uncertain.

## Today in brief

A refined qPCR assay identifies sturgeon sex and includes a control that can help researchers judge whether a negative result is reliable. [1]

## A control helps distinguish negative results from inconclusive tests

Sturgeon sex determination has been limited by a lack of male-specific markers. [1] Britton Ranson Olson said the control helps distinguish a true negative from an inconclusive test or an inadequate sample. [1]

Lake Superior State University's Center for Freshwater Research and Education has tested hundreds of sturgeon samples with the assay and continues testing. [1] Olson said the assay could also inform pathogen detection when samples are limited or their quality is uncertain. [1]

## The day in numbers

- **Hundreds of sturgeon samples**: Tested with the assay at Lake Superior State University's freshwater research center. [1]
