Fish Tissue Metals Test

Mercury and heavy metals in the fish your lake community eats.

Checkout arrives with the store connection. Orders attach to the lake on your account.

Overview

Mercury is the most common reason states advise limits on eating freshwater fish. It enters lakes from the air and from the watershed, is converted by bacteria into a form that accumulates in living tissue, and concentrates up the food chain, so the largest, oldest predators carry the most. A lake can have excellent water quality and still produce fish with meaningful mercury levels, because the two are measured in different places.

This test measures mercury, arsenic, cadmium, and lead in the flesh of a fish caught from your lake. You catch and fillet the fish, record its species, size, and where it came from, and ship the sample to an accredited laboratory.

What this test does and does not decide. Lake Pulse sells tests that measure what is in the fish. We do not decide whether you can eat it. Fish consumption advice is issued by state health and natural resource agencies, which set advice by species, by size, and by who is eating, and their advisory for your lake stands regardless of what a single fillet shows. Check your state advisory first, and treat these results as additional information alongside it, never as a replacement for it.

One of three fish tissue tests. Each measures a different group of contaminants in the flesh of fish caught from your lake.

What problem does this solve for our lake?

    What's included?

    • One (1) fish tissue sampling kit for a single fillet sample
    • All materials required for clean sample collection, packaging, and cold shipping
    • Step-by-step instructions covering filleting, labeling, freezing, and shipping
    • A sample record form for species, length, weight, catch location, and catch date
    • Shipping to an accredited laboratory, with full chain of custody
    • Laboratory analysis for mercury, arsenic, cadmium, and lead in fish tissue
    • A lab report with concentrations for each metal, in milligrams per kilogram
    • Results loaded into your lake's account

    What's not included

    • Fish collection. You catch, fillet, and ship the sample; we supply everything needed to do it correctly.
    • A consumption advisory or safety determination of any kind. That authority belongs to your state agency.
    • Results that describe the whole lake. One fillet describes one fish, of one species and size, caught at one place and time.
    • Regulatory or compliance determinations
    • PFAS or pesticide residues. Those are separate tests.
    • PCBs, another common driver of state fish advisories, which this panel does not cover.
    • Species identification. You record what you caught.

    Requirements

    • Fish handled and frozen promptly after catch, then shipped per the kit instructions
    • Species, length, weight, catch location, and catch date recorded for each sample — results cannot be interpreted without them
    • Fillets prepared consistently, skin on or skin off, and recorded either way
    • One species and one size class per sample. Contaminants vary widely between a small panfish and a large predator from the same lake.
    • Your state's sampling guidance followed where you intend to compare results with its advisory
    • A Plus, Lake Admin, or PRO subscription to have results loaded into your Lake Pulse account
    • Questions about species selection, sampling design, or how results relate to your state advisory? Contact the Lake Pulse Boathouse before you order.
    What you get back

    Results

    • Concentrations of mercury, arsenic, cadmium, and lead in the sampled fillet
    • Results recorded against the species, size, and catch location you provide
    • A dated entry in your lake's record, so results accumulate across species and years
    • The signed lab report filed in Documents & Reports
    • Results are found in your lake's portal, accessible only to Plus, Lake Admin, and PRO subscription tiers

    Pro tips

    • Mercury is usually the metal that matters in freshwater fish. The other three are included because they are measured on the same run.
    • Start with the state advisory. Read what your state already says about this lake and these species before ordering. Testing adds to that picture; it does not replace it.
    • Sample the species people actually eat, and the sizes they keep. Larger, older predators carry the most.
    • Test several fish, not one. Individual fish vary enough that a single fillet is an anecdote.
    • Repeat over years, using the same species and size class, if you want to see a trend.
    • Share results carefully. Fish results move a lake community quickly. Call the Boathouse before publishing anything.
    Results sync to the Portal for Plus, Lake Admin, and PRO subscribers

    Results from this product land in your lake's shared record in the Portal — next to everything else your lake has ever measured, instead of in an inbox.

    About these results

    Every result shows the catch date and the species, size, and location you record. Results reflect one fillet from one fish, analyzed by an independent accredited laboratory using the method stated on your report. Contaminant levels vary by species, size, age, and where a fish fed, so one fish does not represent every fish in the lake. Where the laboratory provides detection and reporting limits, they are reported with your results; a non-detection does not prove absence. Lake Pulse measures what is in the fish; it does not decide whether fish are safe to eat. Fish consumption advice is issued by state health and natural resource agencies by species, size, and who is eating, and their advisory for your lake stands regardless of what a single fillet shows. Check your state advisory first. Decisions, and responsibility for any action taken, rest with you.
