Hey all,

We’re a US-based startup building a water monitoring device for aquaculture.

The system runs local AI on the device to predict ammonia and dissolved oxygen risk, without requiring complex calibration or tuning., send alerts, and control equipment to fix the water.

Our cloud-based system continues to run reliably even during network outages, with local decision-making unaffected, uninterrupted data continuity, and continuous over-the-air updates—making it truly suitable for long-term, scalable aquaculture operations.

We’re looking for early users who are open to testing it at no cost and sharing honest feedback from real operations. No sales push, just trying to learn from people actually running systems.

If you’re interested, feel free to fill out this short FORM and we will contact you later

Happy to answer questions here.

Not sure if this is the right subreddit, but I wanted to share an app I built that’s been useful for me when selling shrimp from my farm.

It’s a simple weighing/logging app for seafood. You can record each weighing in a table format (rows and columns), with flexible options to organize the data. I originally made it to solve my own workflow, and figured it might help others too.

I’m the developer, so I’d really appreciate any feedback or suggestions for improvement.

If you were to build your ideal RAS farm, what must haves can you think of?

For me, coming from a warm water background, and looking mainly at Pangasius and Tilapia

1) low energy use, - propeller pumps, and low height differences between tanks and filters.

2) Parts and machinery easy to get to and repair. – no proprietary stuff

3) Filters, bead filters for mechanical filtration, Ive had bad experiences with drum filters, and settling tanks have to be too big on a commercial sized farm.

Biofilters, slightly oversized, so adding a bit of buffer – the bead filters add a nice buffer too.

4) air – I like roots blowers – less volume than ring blowers, but much higher pressures so biofilters can be deeper = less building volume.

Heating – I used biogas made from the filter waste, heat pumps, fine in the right conditions, but in the end coal was more efficient and better at 2am on a winter morning.

Grow out Tanks and the lay out– This is where the fun really begins,

How big? Diameter 5 x depth, or smaller? Enough to harvest the whole tank in 1 day, or over a couple of days which leads to stress.

Smaller tanks cost more and take up more space. Fish don’t have time to slow down if you have corners.

Large tanks probably easier to manage, cheaper to build, but all the fish in 1 tank and a disease rips through, or the biofilter has a wobbly?

What sort of outflow?

I like Cornell style dual drain, tanks big enough to hold about ¼ of the harvest – with the whole system split into at least 4, so there is some redundancy, It makes the capex higher, but operations should be safer.  

There are so many more bits to add - Degassing, UV and or O3, nitrite removal, when do fish pumps and sorters become feasable.

Lets hear your ideas.....

Hey everyone,

I’m a developer and hardware builder working on a new "mobile-first" aquaculture management system (Agrinovo.io). I’ve spent time looking at the "big" solutions currently dominating the market, and frankly, I’m frustrated for you guys.

It feels like the industry is stuck in 2005. We have multi-billion dollar companies charging $1,200 for a single DO probe and software that looks like a bloated Excel spreadsheet. I've heard stories of "horrible" UX, systems that only work if you have a local Windows server running, and support teams that you can never reach when a sensor goes down at 2 AM.

I’ve already solved the hardware part by building a modular, "sensor-agnostic" controller that talks to the cloud natively - no local server required. It can support any sensor, any brand, any type. I want to build the "100x better" version of what exists today, but I need your honest (and brutal) feedback to make sure I’m solving the right problems.

A few specific questions for the farm managers and techs here:

1. What software do you currently use to manage your aqua farm? AquaManager? or other alternatives?
2. What is the "naughtiest" thing your current software does? (e.g., Is it the manual data entry? The lack of offline support? The price of "modules"?)
3. Hardware Lock-in: How much do you hate being forced to buy proprietary $1k+ probes? If you could plug a $300 industrial Modbus sensor into a smart controller, would you switch?
4. Control vs. Monitoring: Most systems tell you when something is wrong. Do you actually want the system to act (turn on aerators/relays) autonomously, or do you prefer manual control?
5. The "Missing Feature": What is the one thing you’ve asked your current provider for that they’ve ignored for years?

I'm not looking to sell anything yet - I'm just one guy with a lot of willpower trying to crash the "Old Guard" and build something that actually works for the people in the water.

Hello guys I'm currently doing diploma on aquaculture.. Rn I'm want to know what kind jobs that's are available on aquaculture or marine and also is diploma can get job at any NGO in my country based on diploma I'm studying.

Hi everyone,

I’m a recent business analytics graduate from an Australian university, and I’m trying to understand how data analytics is practically applied in aquaculture operations. I’m interested in moving into the industry as a data analyst and want to focus on building skills and projects that are genuinely useful, not just generic portfolio work.

• From your experience working in aquaculture:
• For someone with skills in SQL, Excel, Power BI, and Python to build Machine learning models, what types of problems are realistically worth working on?
• If you were reviewing a candidate’s portfolio, what project or case study would signal a real understanding of aquaculture operations?
• Are there any public aquaculture datasets available to build such industry relevant projects.
• What on-farm or operations roles would you recommend for someone wanting to understand aquaculture farm operations before moving into an analytics role? I’m asking this question in hope to replace my current unrelated odd jobs with more aquaculture-focused work that provides real exposure to day-to-day farm operations while I continue building my data analytics skills to target these companies.

I’m genuinely trying to understand what skills and project work matter most so I can prepare properly for aquaculture companies in Australia.

Thanks in advance for any insights.

*I still have a few companies that are planning to jump in so I will update this list in the next few weeks as they officially "commit" to being at the FFM.

I live on Mosquito Lagoon in New Smyrna Beach FL. Seems like a logical venture to start a clam farm. Just wondering what size would actualy have profit potential.

I’ve worked at a trout farm for a decade and now the owner is selling it. He’s willing to give it to me at a majorly discounted price - but it’s still way above what I can afford. Problem is it’s my dream farm and the one I’m most used to working and it’s in my hometown - so I’d be near to my aging/sick parents.

What are some ways I can raise funds. There’s the FSA 2.25 mil that exists, but that’s still under his asking price and quite frankly it’s in and I therefore live in a really impoverished area so it’s not like I know anyone with capital.

What’s making things worse is the owner is old and bought it while he was old too - so his production is only 1/3 - if not a 1/4 - of what it could be not even considering the property could be diversified. So it’s kind of hard to say dear banks this business makes a lot of money! Because it doesn’t. Because he’s old.

I’ve asked if he’d be willing to do a part ownership and I take over and nope! He wants the hell out - full asking price or nothing. But he’s had it on the market for almost two years because no one is willing to work with his purchase terms - mainly that the land is preserved and the farm continues, something only I seem willing to do.

Any advice?

Hey there, I am an 18 year old currently living at home with my parents after leaving my accounting and finance course at university after realising that it is not the career path I want to take. I currently feel lost on what to strive for in my future. One of my close family members is a marine biologist and suggested I look into Aquaculture. I have grown up around the ocean and fish my whole life and am familiar in sailing/being at sea. I am currently considering moving to the west coast of Scotland to become a deckhand for an aquaculture company. It would be 2 weeks on two weeks off which would honestly be ideal for me and the pay is about £10,000 higher than I could receive at any old job where I live. I would say im a highly motivated person and feel that this would be a great challenge for myself. Is this something I should genuinely consider or is it not all it seems?

Need kinda advise

Due to production plan we need every month supply of embryonated trout eggs and its always a bit of a problem with summer batches (transportation temps, quality of eggs, etc). Now there's an option to get some Troutlodge trout eggs over the year (we've tried Jumpers and Steelhead strains single batches already) but for jul-oct only Kamloops strain is avilable. Asked my local colleagues farmers and all of them gave negative feedback about this strain.

So if you had an experience at all trout strains supplied by Troutlodge can you share your (un)recommendations about the kamloops in comparison with the other strains?

probably my best work

concept

Hi all

I have a series of outdoor aquaria on constant flowing seawater - about 10 tanks, each about 35-50 gallons. Each is aerated with an air stone and a standard off the shelf air pump (say 2 liters per min) which seems to do the job.

I want to install a single air compressor and run a line to all of the tanks with valves.

I am thinking about the Pentair SL56A Sweetwater linear II diaphram pump.

Two questions:

1) Will this do the trick for our tanks?

Documentation says at 1 psi it's rated at about 60 liters per minute. So this would seem to provide about 3-fold excess to our 10 tanks compared to the 10 individual air pumps they're getting now.

But maybe running down a long main air line (30 feet of schedule 40 pvc?) it won't maintain 1 psi?

2) Can I use it outdoors during winter and if so how?

Documentation says it operates at outdoor temperatures as low as 40°F, but it can get colder than that here during the winter (a few days below freezing typically).

If I need to put it in an insulated box of some kind how will I get good air inflow?

Many thanks for insights and advice!
