A subreddit for all things related to the farming of fish, crustaceans, molluscs, aquatic plants, algae, and other aquatic organisms.

A digest of news, articles, and comments from the global aquaculture community.


More about Aquaculture:


Big news: "Scientists Create World's First Fish‑Free Prawn Food"

"...There is intense global interest in Novaq because it solves one of the farmed prawn industry's biggest problems - its reliance on wild fisheries as a core ingredient in prawn food.

But aquaculture has reached "peak fish", where demand for wild harvested fish meal now outstrips supply. Without a solution, soaring world demand cannot be met.

"It is absolutely a critical issue for the global aquaculture industry. There's no more room to get more wild harvest fish, so we've got to find alternatives," Dr Preston said.

"A justifiable criticism about aquaculture is the continuation of catching wild fish, grinding them up and feeding to farm fish."

News of Novaq's development has caused huge excitement around the world, as many thought a fish-free food was impossible..."

Where to buy live orgamisms?

Not gonna lie but there should be a pinned post on top listing where you can buy live organisms like tilapia, catfish, prawns, etc. I know where to buy tilapia(lakeway tilapia) but where can i buy live prawns, catfish, trout, and etc. I'm in alabama soo yeah. I could drive to physical locations but i prefer having them delivered, all the things is just for aquariums, i know koi and comet goldfish could be used. soo yeah. please help me and others where we can buy live organisms online :D

How difficult is Biofloc Shrimp Farming.

Hello all,

I have looked into indoor shrimp farming as I am in the midwestern U.S., but from what I see the profit margins and business model is a bit shaky. but I am now living in Thailand permanently. and now that I will be in Thailand I have been looking at potential businesses that I can do with help from my wife.

My question is, how hard is it to learn the Biofloc method to raise Vannamei shrimp? I was thinking of starting with just a small tank around 2x2 meters just to learn the processes.

I have also looked into doing a 2-day course with RAS Aquaculture out of Malaysia if I decide to experiment with Biofloc shrimp farming.

It is also very hard to find information on RAS and Biofloc shrimp farming in Thailand, as most farms still farm shrimp the traditional way, but I have read some studies and information stating that it could be a very good time to start this sort of operation due to the issues the shrimp farming industry has had in Thailand, mainly with diseases and other factors.

I am going to be living in Northwest Thailand, far from the coast and in an area with fewer shrimp and freshwater prawn farms in relation to the rest of the country, with most farms being near Bangkok or the coast.

My thoughts, (and they could be wrong) is that a small to moderate Biofloc operation might work as I am still in the 2nd largest city of Thailand, there doesn't seem to be much competition in the local area, and being so far from the majority of the farms in the south, I could sell the shrimp to the local restaurants, and have my own stalls at the markets, etc. (the sales are where the wife comes in).

Anyways, any good info is appreciated, and if you have any regional information for northern Thailand and Biofloc farming, that would be a bonus.

Marine 50 gallon tank?

Living on the creek with supply of assorted fish do I require a sump for my new setup tank 50 gallons? Will a protien skimmer work alone? What else will I require?

Help please

Im trying to start planning to get some setups built for fresh and saltwater aquaculture in my land lab to teach my students as well as let them raise and keep these fish later down the road. Since im a floridian who loves to fish as well as the majority of my students i know how much a good bit of live mullet can set you up for a good day for just about anything so i thought id try raising some however i cant find any local or commercial mullet farms anywhere and so id like to ask yall for help and see if anyone knows of any mullet farms that sell young mullet that i can use as starters preferablly within florida since transporting fish across long distances is always a hit or miss of getting what you ordered or your fish dying or developing issues along the way.

Suggestions for fish/ invertebrates to grow in ~1,000 gallon RAS

Im running 8 ct- 1,000 gallon tanks with White Nile Tilapia right now, stocked at about 250 fish per tank. Tanks are interconnected with 2ct - 200 gallon biofilters with circulating plastic biomedia. By the end of May/ June all the fish will have been harvested, they are being harvested now at 400 fish every 3 weeks. Tilapia isnt popular with buyers right now, they are more interested in higher quality crops such as salmon, trout, freshwater prawns etc.

What would you suggest I grow in the system? Im located in South Florida (water temp gets 90-95F in the summer). I am also considering investing in chillers to maintain lower tank temperatures if need be.

Note: tanks are 4 feet deep, 8 foot diameter

Yeast as Algae substitute in Rotifer production

I'm running a barramundi hatchery and I've been using Nanno 3600 from Reed Mariculture for our rotifers. It's been great, but man, it's getting expensive. So, I've been thinking about switching things up and trying out yeast instead, probably as a partial solution.

I figured I'd ask you all for advice and insights. Have any of you experimented with using yeast as a substitute for rotifer feed in your cultures?

I'm particularly interested in:

  • Feeding Tips: How did you introduce yeast into your feeding routine? Any tricks or methods that worked well for you?
  • The protocol: do I feed the yeast directly to the tanks? do I need to feed the yeast sugar? how much do you feed per mil rots?
  • Best Yeast Strains: What yeast strains have you found to be the best for larvae?
  • Success Stories or Hiccups: What were the results like when you made the switch to yeast? Any big wins or challenges along the way?

Long, Narrow Pond?

Would a 3.5’ wide x 3.5’ deep x 10’ long (1m x 1m x 3m) pond/pool work? Right now I’m looking into tilapia, bluegill, or catfish. I’d also be filtering the water ≈3-4 times per hour.

Seeking advancement in the field.

Sorry y’all, this is going to be a TALL order. But I’m looking for the next step in Aquaculture. Or at least the same position but better pay. I’m an Aquaculture Technician with 3 years of experience. I prefer RAS but am open to net pens or any other system.

I’d prefer something NOT on the east coast. And preferably above $19/hr

My current job started at $18 and I’m now at $19.75, so I understand a raise is something I might have to work towards. But with 3 years in RAS, I know that puts me a step above entry-level.

Sorry for the rant. But if you all know of any farms in the US needing a hardworking Technician or potential Assistant Manager, please let me know!

P.S. - Not California lol

I want to try to spore and grow seaweed at home, what equipment do I need?

I am interested in a project and trying to spore and grow wild seaweed in a tank at home. I am not sure what sort of equipment I would need.

The list I have right now consists of:
-tank
-aerator
-chiller/temp control
-lighting

If anyone has any experience with seaweeds I would love to have some advice on a basic setup as I am pretty new to aquaculture.

Any guides or literature would be a great help too! Thanks all

Food in water

Does anyone here consume alot of knowledge and info from different places. If you have, this is for you. Would like an understanding of what's the dream jobs in this field. To understand.

Like the animator people dream job is probably working at disney or studio gibil

And the lingisiust people may be something like creating a language for movie

Classical types of musicans would be some kind of highest end classic music symphony or orchestra or whatever those things are called

All fields and topics has dream jobs that represent the highest end of those fields

Teachers .. teachers are likely something like private schools, or being principles ... or more likely starting their own schools or teaching on youtube to reach many more people

Another way of asking the same question as above is what is the highest end of your field

I don't know anything about aquaculture. Would like to have an understanding of all the important things of this field, and to fill in my knowledge gap and of what I understand about things

Sites are good too. Would also like all of the most interesting and very informative web pages you've seen over time

Haven't explored this topic or field before but I'd imagine one of the highest ends is to invent and use advanced tech to reach the various longterm goals that people in aquaculture have?
