Application area
Aquaculture is MEGUMI's first international focus. This page lists what has been explored, what was observed, and how far each record has been verified.
Fish and shrimp, across several production environments.
Aquaculture carries the largest accumulated field experience in the source materials, it is central to food security in the Middle East and Africa, and its production cycles make structured local measurement practical.
Spotlight
Two vannamei shrimp contexts have been explored in Japan with MEGUMI BIO's 100% natural Japanese biotechnology. Both records are still under source verification, so no performance figures are shown.
A collaborative trial compared four conditions: the technology with high dissolved oxygen, the technology alone, high dissolved oxygen alone, and a control. The source material reports the strongest late-stage growth and fastest attainment of market size in the combined condition.
The contribution of each factor cannot be separated from the combined result — it is not attributed to the technology alone.
A tank trial examined early-stage stability. The source material describes more active swimming and lower protozoan proliferation in the test condition, with possible relevance to water quality.
Preliminary observations only — not a disease-prevention claim. Needs source verification and local validation.
The goal is not to reproduce a Japanese result. The goal is to build reliable local evidence under your own farm conditions.
Recorded before and throughout a trial, so a result can be interpreted rather than just reported.

Outcomes
The same numerical measurement may not represent the same biological state on two different farms. A given water temperature, oxygen reading or density means something different depending on species, life stage, season and system design.
That is why context is recorded alongside every value. Without it, a result cannot be compared between sites or reproduced later — and comparability is what makes evidence commercially useful.
Each record on this page carries one of these positions.
Recorded in a documented field or production setting, with the source shown.
Reported figures are still being checked against a public source; qualitative wording only.
Not yet tested in other species, climates or production systems.
12 aquaculture records are listed below: 3 with a checkable source attached, 9 with source verification in progress.
Each record shows species, setting, what was observed and its evidence status. Records are expandable.
Where a source figure has not yet been formally verified, the record shows qualitative language and a verification label instead of numbers.
JapanCommercial flounder farm, Saiki City, Oita Prefecture
A 2024 Japanese publication reports two field trials at a flounder farm in Saiki City, Oita Prefecture, where a microalgae-derived extract was mixed into feed. The report describes observations relating to survival and growth compared with the control, with gene-expression findings discussed in relation to lipid metabolism and innate immunity. These findings belong to that specific species and production setting and are not used as a performance benchmark for other aquaculture applications; local validation is still required elsewhere.
JapanAquaculture under high-water-temperature conditions
A June 2026 aquaculture trade feature discusses the microalgae-derived material, seedling robustness in farmed fish, and the possible relevance of this work to high-water-temperature conditions. It is published context for why the topic is being studied, not evidence of a guaranteed outcome under heat stress.
JapanCommercial land-based flounder production
A Japanese flounder producer in Saiki City publicly describes mixing the microalgae-derived material into feed as part of its rearing method and reports greater body weight and practical operating experience. This is real-world producer context, published by the producer itself, and should be read separately from peer-reviewed or academic evidence.
JapanResearch facility
Owner source materials describe collaborative university research in Japan examining health and immune response markers alongside growth and feed efficiency. The institution and reference are still being confirmed and the material remains source verification in progress, so no verified performance conclusion is published from this record.
JapanClosed culture system with high dissolved oxygen supplyGrow-out
A collaborative grow-out trial in Japan compared four conditions: the technology with high dissolved oxygen, the technology alone, high dissolved oxygen alone, and a control. The source material reports the strongest late-stage growth and fastest attainment of market size in the combined condition. Because that condition combines two factors, the individual contribution of the technology cannot be separated from high dissolved oxygen. Source verification is in progress, so no figures are shown.
JapanFreshwater farm production
Rainbow trout field-use records from Japan include observations relating to growth, body weight, feed efficiency and crowding- or stress-related conditions. These observations come from owner source materials and remain source verification in progress. They are presented as field context rather than verified performance results.
JapanElevated water temperature
Early, exploratory observations at elevated water temperature. Too preliminary to support any expectation and listed here only for transparency.
VietnamCommercial shrimp production
A shrimp field evaluation outside Japan is described as under way. No results are reported here.
JapanBroodstock and egg development
Exploratory reproduction work has looked at fertilisation and hatching. This is early research, not commercial proof.
JapanVarious commercial aquaculture environments
Source materials report extensive accumulated field experience in Japanese aquaculture over many years. The scale figure is held back from publication until a formal evidence record is attached.
JapanIndoor tank trialFry / early stage
A preliminary tank trial in Japan looked at the early stage of vannamei shrimp. The source material describes more active swimming and lower protozoan proliferation in the test condition, with possible relevance to early-stage stability and water quality. These observations are preliminary, are not a disease-prevention claim, and need source verification and local validation.
JapanMarine cage aquaculture
Marine aquaculture observations exist for yellowtail and grouper. Results are not summarised here because verified figures have not yet been entered.
A first international trial should define these before it starts.
A local trial is most useful where production data is already being recorded.
Japanese experience provides a starting point. Local conditions still matter.
Tell us the species, system, scale and the indicator you want to improve. We review each enquiry and reply with whether a small local trial is a practical next step.
Pilot participation is reviewed, not automatically accepted. A structured pilot needs a comparison group and consistent record-keeping to produce usable data.
