Right then, let's get to it. You wanna know how to use them special bacteria, the photosynthetic ones, for your fish and shrimp? It's a bit like givin' your pond a super-powered cleaning crew that also feeds your critters. Smart, eh?
Key Takeaways: PSB for Your Ponds
So, what's the deal with these Photosynthetic Bacteria, or PSB as folks call 'em? Well, they're tiny little living things, like super-small bugs, but the good kind! They're special 'cause they can take sunlight and turn it into energy, kinda like how plants do. This means they're not just floatin' around; they're busy workin'. In fish farms, they do a whole heap of good. They clean the water by eatin' up nasty stuff that can make fish sick. This helps the fish grow better and stay healthy. It's all about keepin' the pond in a nice balance. Companies like Pangoo Group are really into these eco-friendly ways to help fish farmers, 'cause the old ways sometimes just don't cut it no more. These PSB are like a modern fix for healthy ponds, and they're way better for the earth too. It aint just about cleaning up; it's about making the whole pond a better place for fish to live and thrive.
Now, Pangoo Group, they've got some real nifty PSB products. They don't just chuck any old bacteria in a bottle, oh no. They've got stuff like "Aqua Photosynthetic Bacteria" and "BioAqua" which are made to really help out your pond. What's their secret, you ask? Well, they got this big "strain bank," which is like a library of different bacteria. From there, they pick the best ones, like the "fastest ammonia-eater," to put in their products. This means you're gettin' bacteria that are proper good at their job. They take quality serious too, with all them fancy certificates like ISO9001 and stuff, so you know you're gettin' somethin' that's made right and is pure. The kinds they use, like Rhodobacter, are tough cookies and really good at gettin' rid of ammonia and other yucky bits. This aint just some random mix; it's a carefully chosen team of tiny helpers for your farm.
One of the easiest ways to use these PSB fellas is just to pour 'em straight into the pond water. Sounds simple, right? And it is! Once they're in there, these bacteria use the sunlight to munch on all sorts of dissolved yuckiness – stuff like ammonia, nitrite, nitrate, and even that stinky hydrogen sulfide. A real cool thing about many PSB, especially the Purple Non-Sulfur Bacteria (PNSB) types, is that they do their photosynthesis without using up the oxygen in the water. This is super helpful, 'specially at night when oxygen levels can drop. Pangoo's "Aqua Photosynthetic Bacteria" is made just for this. The numbers show it works too! They've seen ammonia go from 8 parts per million (ppm) down to just 1 ppm in about four days. Other smart folks found similar things, with ammonia dropping heaps in tilapia tanks. They even reduce nitrites and nitrates. Pangoo says about 10 ml for a small tank or 20 liters for a big half-hectare pond is a good start, maybe more often if you're feedin' a lot. It just makes the water a much healthier place for your fish.
Another clever trick is mixin' PSB right into the fish food. Why'd ya do that? Well, PSB cells are packed with good stuff. They got loads of protein that's easy for fish to digest – some types are up to 70% protein! Plus, they're full of important things like special amino acids, lots of vitamins (B vitamins, A, D, and H), and pigments that can even make your fish look more colourful. When the fish eat this, it helps their tummies work better, they get more goodness from their regular food, and it gives their immune system a good ol' boost. For instance, tilapia fed with PSB grew way faster and converted their food into growth much better (that's FCR, if you're fancy). Shrimp did better too, and carp fry had a much higher survival rate. Pangoo even mentions prawn larvae growin' 18% faster with a PSB "snack". Products like Pangoo's FA3 Feed Starter can be part of this strategy. It don't cost much either, somethin' like 0.005 USD per kilo of feed. So, it's good for the fish and good for your wallet.
Alright, so what's this Biofloc Technology (BFT)? It's a way of farming fish where you grow a thick soup of tiny living things – bacteria, algae, all sorts – right in the water with the fish. This "biofloc" then cleans the water by eatin' up waste, and the fish can eat the floc too! It's like a natural recycling system. Photosynthetic Bacteria fit in here real nice. They help keep the important carbon to nitrogen (C/N) ratio balanced, which is super important for biofloc to work right. Pangoo says PSB can "sharpen carbon-nitrogen balance, cutting extra molasses cost," which is pretty neat. They also help with nitrogen bits and can break down leftover food. Plus, the PSB themselves become part of the biofloc, making it even more nutritious for your fish or shrimp. Studies have found that bacteria like Rhodobacteraceae, which are a type of PSB, are often the main players in healthy biofloc systems. Pangoo even has a guide for "Biofloc Fish Farming" that probably tells you more about using their PSB in these systems. It just makes the whole BFT thing work better.
Now here's a clever idea: biofilms. Wot's a biofilm? It's when these tiny bacteria stick to a surface and grow into a whole community, all cosy together. If you get PSB to form these biofilms, say on special plastic bits or even just on surfaces in your pond, you concentrate their cleaning power. It's like havin' a dedicated water treatment plant right where you need it. As water flows past, the PSB in the biofilm grab onto the bad stuff like ammonia and other muck, and clean it up real good. There's been studies showin' this works. One used a mix of PSB including Rhodopseudomonas and Rhodobacteria on some brushes in a system for cleaning up mariculture (seawater fish farming) water, and it removed a massive amount of pollutants. Another study, while it focused more on nitrifying bacteria (which are also super important, especially products like PRO/09 Nitrifying Bacteria), showed that growing bacteria on sponges in shrimp tanks made the shrimp grow bigger, survive better, and kept the water way cleaner. Imagine combining the power of PSB with these nitrifying bacteria in a biofilm – that’d be a super-duper cleaning team!
Using these PSB from outfits like Pangoo Group ain't just about chuckin' 'em in and hopin' for the best. Nah, there's a bit of know-how to get 'em workin' their hardest for ya. First off, they're photosynthetic, right? So they need light! Ponds should get a good six hours of sun, maybe even eight to ten is best. But careful, too much strong sun right at midday might be a bit harsh, so adding liquid PSB at dawn or dusk is often a good shout. Temperature matters too. Keep liquid PSB stored cool, like in the fridge (5-20°C is ideal). In the pond, if it gets below 15°C, they slow down a bit. And this is a big one: chlorine kills 'em! So if you're using tap water, make sure all the chlorine is gone before adding PSB. Same goes if you've used chemical cleaners in the pond, wait a day or two. Also, the water's pH should be round about 6.5 to 8.0. If it's off, somethin' like Pangoo's AQUA/09 PH Conditioner can help. And don't forget, you can team 'em up with other good stuff, like Bacillus products (Pangoo's AQUA/02 Sludge Remover is a good 'un) to break down sludge even faster, or an "AQUA Health Booster" for an extra vitamin kick for your fish.
The world of PSB in fish farming ain't standin' still, no sir. Smart folks are always comin' up with new ideas to make 'em work even better, pushing for sustainable aquaculture growth. One really neat thing is called PSB encapsulation. It's like puttin' the bacteria in tiny protective bubbles. This helps 'em last longer, survive tough conditions when you add 'em to the pond, and even get 'em delivered right to where they need to go, like inside the fish's gut! Studies show these encapsulated PSB can be way better at removing ammonia and other nasties. Then there's makin' even better strains of PSB. Scientists are lookin' for new types with special powers, or even using fancy tools to tweak the ones we already have to make 'em super-efficient at eatin' waste or fighting off bad bugs. Pangoo Group is right in on this, with their "strain bank" and all. And as fish farming gets more high-tech, with things like Recirculating Aquaculture Systems (RAS) and advanced biofloc, PSB are gonna be even more important for keepin' everything balanced and clean. It's all about growin' more fish with less mess, and PSB are a big part of that future.
