Lake-incubated Lake Champlain lake trout embryos accumulated vitamin B1 (thiamine) around hatching and in the weeks afterward, while paired embryos reared in a laboratory did not show a comparable rise. The finding suggests that natural incubation conditions matter to thiamine availability—but it does not yet reveal exactly how embryos gain thiamine or show that the increase improves survival.
What the study found
In a 2026 study, researchers split fertilized Lake Champlain lake trout eggs between incubation in the lake and controlled laboratory rearing. They measured thiamine at four developmental stages and analyzed lake water. The University of Vermont’s account reports significant thiamine increases in lake-incubated embryos by hatching and during the following weeks; the paired laboratory embryos showed no comparable increase. Lake trout eggs incubate for more than five months before hatching, according to the release.

The team also detected thiamine precursors and byproducts in Lake Champlain water. That finding is contextual evidence, not proof that lake water alone supplied the additional thiamine. The study does not identify the exact source or route by which embryos gained it. University of Vermont research release
How the lake and laboratory comparison differs
| Incubation setting | Reported thiamine result | What it does not establish |
|---|---|---|
| Natural incubation in Lake Champlain | Significant increases by hatching and in the following weeks, as described in the University of Vermont release. | The precise uptake route, the contribution of lake water alone, or a survival benefit. |
| Controlled laboratory rearing | No comparable increase in the paired embryos, according to the University of Vermont release. | That laboratory conditions explain all differences between wild and hatchery fish, or that the result applies to every hatchery. |
This is a comparison of thiamine concentrations across developmental stages, with water chemistry as supporting context. It is not a demonstrated comparison of survival, mortality, or treatment effectiveness.

Why this challenges hatchery-based assumptions
Thiamine deficiency complex (TDC) is associated with inadequate vitamin B1 and can involve behavioral and neurological abnormalities and high mortality in newly hatched fish. Hatchery staff can mitigate effects with thiamine treatments, according to the University of Vermont release. The study’s lead author, Matthew Futia, said: “Prior to this study, practically everything we knew about the effects of TDC on newly hatched fish was based on studies in labs and hatcheries.”
The result shows why observations from controlled settings may not capture every part of thiamine dynamics during development in the wild. It supports examining incubation conditions and local water chemistry alongside egg thiamine, rather than assuming that hatchery or laboratory patterns describe natural incubation completely.

What the result does—and does not—say about fish health
The reported outcome is a change in thiamine concentration. The account does not demonstrate that this increase prevents TDC, reduces embryo or hatchling mortality, or improves recruitment. Those are separate biological outcomes and should not be inferred from the concentration finding alone.

How far the findings can be generalized
The reported comparison concerns Lake Champlain lake trout. It does not establish that embryos of other species, or lake trout in other lakes and incubation environments, gain thiamine in the same way. The release does not provide numeric effect sizes, sample sizes, or detailed assay estimates, so the scale of the increase cannot be quantified from that account.
