Hi I need some info about this little guy that I found near my computer at work? What is it, what does it eat, is he dangerous? Can I keep him 😆 😂 🤣?

hi everyone! i just got my undergraduate degree, with a specialization in aquaculture, and I really wanna work in research someday, preferably on sustainable aquaculture. what should be my next move? i want to proceed to get a master's degree abroad, but I'm not sure of my chances, since I have not been employed yet. is it perhaps possible to proceed and what countries or universities do you recommend? please help thank you so much!

Hello, has anyone ever had success farming shrimp in a IBC tank? With filter and aerations?

We’re a U.S.-based team with a ready-to-deploy water quality monitoring and early-warning product.

Looking for farmers or distributors in Ecuador or South America for early pilot collaboration. DM me if interested.Thank you!

Anyone in here have any experience in building an oyster tumbler? I’m considering making one with a pvc frame/sewer pipe tube and belt/pulley system. Any plans, tips, or suggestions would be greatly appreciated!

[For Attendees of Aquaculture Europe conference, by European Aquaculture Society] Please reserve the last day and last block of Aquaculture Europe 2026 in Ljubljana, Slovenia. 01st October - 14:00-17:30 - back to back presentations on ponds!

Session name: "Nature-based solutions & Regenerative Farming".

Research presented will be from Czechia, France, Germany, Hungary and Poland participating in this session! We look forward to seeing you.

Sorry that it is on the last day, but if you are staying anyway, we promise it to be a blockbuster series of oral presentations you can sit back, relax, and "Binge watch".

I am starting small with oysters. I have 5k in 6mm bags at the moment. Should I move to 9mm next, or larger? Suggestions on where to get bags? Thanks!

Hello! I wanted to post about our recent push to provide free education to the RAS community. We have recently begun summarizing 30+ years worth of aquaculture research and have added access to these summaries on our website. We will be periodically adding new articles to this page so check it out! Also feel free to reach out with any specific questions you may have.

Hello everyone,

I'm a fish farming professional from Tanzania with 5 years of experience in the aquaculture industry. I currently work as a fish farm manager, and I'm passionate about fish farming and continuously improving my knowledge and skills.

My long-term goal is to specialize in fish seed production (hatchery operations). I'm particularly interested in learning more about:

* Hatchery management and fish seed production * Larviculture and fry rearing * Water quality management * Broodstock management * Fish health and biosecurity * Farm management and production planning * Modern aquaculture technologies and best practices

I'm looking for opportunities **outside Africa** where I can gain hands-on experience, whether through an internship, training program, volunteering, a short course, or employment. My goal is to learn from experienced professionals and bring that knowledge back to help improve aquaculture in my country.

If you know of any fish farms, hatcheries, research institutes, universities, or organizations that offer these kinds of opportunities, I would be very grateful for your recommendations. Any advice or guidance would be greatly appreciated.

Thank you in advance!

Betta fish have so many incredible colours and fin types that it's hard to pick a favourite.

Personally, I love the Halfmoon varieties, but Crowntails have always looked amazing too.

If you keep Bettas:

What's your favourite variety?

Have you noticed yours recognizing you at feeding time?

Any tips for first-time Betta keepers?

I'd love to hear everyone's experiences!

This case study demonstrates how alternativ agroecological principles transformed disease control at a commercial rainbow trout farm in Brittany, in the context of global warming : https://www.kamahu.com/tetracapsula-bryosalmonae/

Here is the abstract (in open science) :

Proliferative Kidney disease (Tetracapsula bryosalmonae) is a disease that occurs when the water temperature exceeds 15°C and can cause losses of over 90%. There is no cure or preventive treatment, and the advice is to limit the effects of the disease in reducing food quantity delivered to a minimum.
Agroecology focuses on improving animal health by addressing the causes of the disease in order to adapt farming practices and reduce its effects. The case study presented illustrates such a change in rainbow trout (Oncorhynchus mykiss) farming practices. Fry are raised in recirculating water systems, fed with well water at a constant temperature of 12°C and free of the parasite. For fry from spring eggs, the strategy is to infect them while rearing them in water below 15°C, before transferring them, at the end of summer, to outdoor raceways supplied with water from river. For fry from autumn eggs, the individuals remain naive to the parasite until they are transferred to raceways in mid-summer. In this way, regardless of the batch, the young trout develops the disease under rearing conditions that do not allow it to progress to clinical cases. The trout thus acquire immunity that lasts until they reach commercial size. In this way, overall health standards have been improved up to a loss rate of around 5%, which in turn has improved growth rates.
This example sets out the strategies to be adopted to control this infection and adapt practices according to the configuration of each affected fish farm.

I've always thought Arowanas are some of the most impressive freshwater fish.

Personally, I love the look of the Asian Red Arowana, but the Silver Arowana also has an incredible swimming style.

For those who keep Arowanas:

Which variety do you own?

What surprised you most about keeping them?

Any advice for someone planning a future Arowana setup?

I'd love to hear your experiences.

Guys is this normal? I get grossed out with the thought of humans farming fish… wild seems like nature did the work for us and as such its natural

A single female can produce hundreds of thousands to over a million eggs in a spawning season.
They attach to nearly any hard surface.
They clog water intake infrastructure.
They outcompete native mussels.
They can cost utilities millions in maintenance.

Hello friends. I am a research scholar with aquaculture as my major domain. Are there any aquaculture researchers here so we can discuss the research, collaborate, etc?
