Hello, I am wondering if its possible to aquaculture farm prawn? If it is possible how do you make a pond for giant river prawn and where can you get them?

Hello folks, I have a problem and would like to see what the best solution is.

I`m working on small fish farm in Croatia (capacity around 40t per year) and we are farming seabass. Our primary goal is to grow them to 1.5-2 kg, and we succeed. But last 2,3 years, during summer, oxygen saturation drop under 70% and and we have a high mortality rate, especially among the younger. Except that, we stop feed them during summer, when they supposed to grow most.

I was searching on internet how to increase oxygen level and find that some aerator pump, difussor pump, surface aerator, home made venturi pipe, normal water pump just to mix water, mixing of water on the surface to increase oxygen.......and lot of other solution.

We have 36 cages (picture below), each 10x10m and 8m in depth, they are all together, and I thought to "bring" oxygen in 4 or 5 different places all over fish farm.

Does any of you had similar problem and what is best way to solve it?

Selling the land is not an option so I’ve been thinking about how I can make use of my parcel in North Carolina. I’m from and still live in NY so I don’t have any experience. How does one learn the trade of aquaculture? I’m obviously willing to start small and invest the time in learning

Does anyone one here have experience with preventing fish from jumping from large industrial sized (10000L +) sized raceways? Currently looking for the best solution to this problem. Any photos or images would be greatly appreciated. Many thanks!

Some background: I'm currently going for my masters in environment science part-time while I work full-time (somewhat flexible work schedule makes this possible), and I need to come up with a project to fulfill my graduation requirements.

I recently got involved with an environmental education, research, and restoration nonprofit group that runs a state-owned estuarine natural habitat refuge that used to be the grounds of a summer camp. There are old cabins and some bigger buildings on site, one of which has an old, defunct indoor pool in it. The director of this nonprofit expressed to me that it would be cool if we could convert the old pool into an oyster aquaculture facility to have a home-grown supply of a native oyster species to establish an oyster reef parallell to the property's salt marsh for restoration purposes. With his permission, I spoke with my advisor and she said this project could be used to fulfill the research requirements for my degree. More importantly, it would be a huge improvement to the facilities, and the oyster reef would improve water quality and reduce marsh erosion by serving as a wave energy buffer.

My question for this subreddit is: would this be possible? Is it feasible to convert a several-decades-old indoor pool into a functioning oyster aquaculture facility? I'm very inexperienced in the field of aquaculture so I'll take any thoughts, concerns, advice, recommendations, anything you all can offer me.

I’m looking to start up an RAS for mudcrab in the US both as a proof of concept and possible commercial venture. I can easily source equipment to build a system up, but I’m struggling with sourcing crabs. Found a couple threads where people ran into the same problem.

I’m not looking for a consistent supply of soft crabs for a “fattening” system like used in Asian countries. Because of the difficulty in acquisition, I would have to find a way to sustain a population through breeding. Initially I want to isolate a few specimen and focus on breeding and raising from spawn, as I see it being the main challenge. Then I will adapt a healthy population to an RAS and repeat the cycle. With this being the case, I need a small shipment of LIVE crabs. I’m struggling with accomplishing this.

I’m curious if anyone has connections who’d be willing to ship me a smaller shipment. I’ve found Indonesian and Singaporean suppliers, but all require 1000+ kg shipments. Way out of my ballpark. If you know anyone who could help me out, please let me know. My resources are stretched thin and I’m avoiding intercontinental travel if at all possible.

UPDATE 1/23/25

I’ve come to realize my original post did not outline the scope of this project very well, so here’s some more details. I’m looking for collaboration and ideas, so feel free to share/criticize if you’d like.

I originally stumbled across this idea a couple months back on a YouTube video displaying the already thriving and active aquaculture of mud crabs in some Asian countries such as Vietnam, Malaysia, and Indonesia. It showed an RAS being used in landlocked areas to grow out mud crab for consumption. As an avid seafood enjoyer, I often find myself frustrated with the ridiculously high price and low quality of crab in my area. I saw this project as a possible proof of concept with two major goals. Fresh seafood of a higher quality, and cheaper prices due to no need for quick shipment across the country.

I initially researched the system itself, and gained an in depth understanding of it. Then, I searched and sourced components, and roughly estimated cost per unit. Once I had a generalized cost, and knew I could afford this… I started looking for crab and ran into a few issues.

Being a non native species, I was initially sure importation would be impossible, because why would someone not already be doing this? I reached out to federal fish and wildlife services and they got back with me quickly. Here is what they said:

“'Scylla serrata' is listed as appendix Il under CITES. The import of Appendix-ll specimens into the United States does not require an import permit but does require an export permit (issued by country of export). An export permit may be granted when the export will not be detrimental to the species' survival and specimens were legally acquired.”

This confirmed that importing was completely possible, and didn’t combat any legal requirements within reasonable reach.

At this point in the project, I’m still sourcing crabs. Initially, I need to get a breeding population up and running efficiently. I’ve researched this extensively and found great help from ‘RAS Aquaculture’ from YouTube through WhatsApp. They’ve helped a ton with sorting a bunch of grey areas out for me. I’ve reached out to several suppliers from above listed countries, and most have extremely high MOQs (100-1000kg), or have never shipped to the US before and avoid it completely.

This leaves me with a few options: Option1: keep searching for suppliers who meet my requirements. This may take some time, but i know it’s possible and understand what’s needed to do so. I’m actively reaching out to many people through Facebook and WhatsApp, scouring the internet for a connection.

Option2: travel abroad and deal with transportation myself. While this is a sure fire method, it’s also the most costly time wise. I do work full time, and finding even a week to fly across the world for this is gonna be tough. I’m saving this option as an absolute last resort.

Option3: I’ve recently discovered Mud Crab was introduced to Hawaii a while back to establish a commercial fishery. They go by the name ‘Samoan crab’, but are actively available. I’ve already talked to a few people through Reddit who have helped me with information regarding this. This is much more doable for me, and I’m planning on making a trip out there early summer this year.

I've seen people grow bull kelp and pond algae but I'm curious about growing edible species of brown algae like Ecklonia, just curious if it's possible and/or practical.

Hey everyone,

My uncle is starting a small crab farm operation and was wondering what testing kits are recommended. Looking for specific brands or products.

I'm also curious as to what you guys would recommend to test for.

Hi everyone,

I am a Master’s student in Aquaculture, currently based in the UK. I am looking for a 3-month internship in the EU.

I have been searching on LinkedIn, aquaculture job sites, and sending emails (including my CV) to ask about internship opportunities at some companies. However, I have received only few responses so far. Some companies do not take interns, while others that work on projects will be on a break during the period I am available.

I am interested in fish nutrition and fish feed and have gained relevant experience through previous internships and undergraduate thesis. However, as I started my Masters program, I realized that I shouldn’t limit myself and need to know more about the sector. Therefore, I am open to learning about other fields too, such as fish physiology or RAS systems, at any company or research institution.

If anyone has any leads or advice on how to approach and contact organizations for internships, I would appreciate it.

Dear Aquaculture users, I have been giving an assignment to do regarding creating a sensor hub (a conglomeration of different sensors) to test the water quality for salmon farming. I was wondering if anyone would have experience in salmon farming and could offer me some insights into what should typically be tested for. Thanks for the help 🙏

Looking to hire an expert in Indoor Shrimp Farming that will be open for a project.

Hi, I’m a student working on a research project that involves designing a solar powered floating fish feeder and fishpond monitoring system. One key aspect of my project is ensuring sufficient oxygen levels in the pond.

Here are the details of my setup:

• Pond size: 24 cubic meters (5m x 7m x 1.2m)
• Fish type: Tilapia in the juvenile stage (around 1000 fish)
• Power source: Solar
• Objective: Automated aeration

I’m looking for guidance on the following:

1. What type of aerator (e.g., paddle wheel, air stones, diffuser, etc.) is best suited for this pond size and fish type?
2. Are there specific aerators that work efficiently with renewable energy sources?
3. How do I calculate the required aeration capacity or oxygen transfer rate for optimal fish health?
4. Any tips for integrating the aerator with an automated system powered by a microcontroller?

Thank you for your time and insights. Any advice or recommendations would be greatly appreciated!

Hello. I'm building a tilapia system outdoors in an IBC tote. It will be 275 gallons. Does anyone have a suggestion for an outdoor pump that's either solar (preferred) or battery operated?

Hello I am a betta breeder that just moved to Central Florida. One thing I didn’t take into account was how cold it would get in the winters. The temperatures get in the 30 and 40 Fahrenheit which is too cold to heat the fish I breed which are bettas. My plan was to grow them out in large 4ft by 8ft concrete ponds but the only obstacle I’m encountering is how I’m going to be able to heat them up. The only option is I is to use big heaters but I’m guessing that will bring up my light bill by a lot. Anyone have any other ideas as to how I would be able to heat up these outdoor ponds?

Looking for insight on next pair of waders please.

Commercial wild harvest shell fisherman here. Typically jerk take for hard shells and it’s pretty tough on anything thus far. Looking at the guy Cotten neoprene but still kickin tires.

Thanks

So not really sure if this is the right place for this if not I'd love suggestions. So I am currently enrolled in an associates program for aquaculture & fish hatchery management. I know just a two year degree is limiting. But my question is, how insane of a dream is it to eventually get to work in death valley/amagarosa valley even if it's just relative grunt work? I suppose maybe a better question is how much more education or connections would I need to build to get hired in with US fish and wildlife realistically. I'm 32 currently so I just wonder will I be broke and in school until I'm well into my 40s if I try for something like this?

Feliz Navidad y mejores deseos de un nuevo año repleto de oportunidades y excelentes resultados a todos nuestros amigos, colegas y clientes !

Seasons Greetings & Merry Christmas and a new year filled with opportunities and excellent results to all of our friends, colleagues and customers !

I’m not qualified enough to draw conclusions. The Maldives has a lot of ocean but barely any fish farms? Why do you think so

Hello! I am a student looking for someone who has membership to SeafoodSource.com. I’m working on a project but I can’t access the second half of this one article without paying the full $325 membership. Is anyone willing to copy-paste it for me?
