Swim bladder problem in fishes

Went online to search about this. Came out with the report.

It may not be accurate. But at least there are some info which i can share with the members here..

There are two parts actually. First is the introduction and how it affects fishes. Secondly would be the causes of swim bladder problems.

I'm posting the first part. The second part may take quite a while since im still gathering on the info for better approach on dealing the problem..

Cheers!

Chapter 1: Swim bladder problems in Fish


Possible Causes: Pseudomonas Fluorescens, Aeromonas hydrophila

Infectious: Yes
Reoccurrence: Yes

Symptoms: Fish floats to the surface, often upside down, and is unable to swim down. Alternatively the fish may be unable to swim off the bottom of the tank or fails to swim upright instead it rolls from side to side.

Other characteristics: Poor nutrition [may subjected to appear thin even though is eating well], body near the swim bladder organ may appear swollen, disintegrating of colour [may appear blackish]

Introduction Aeromonas Hydrophila

- Is a pathogenic bacterium
- Bacterium can be found in marine, brackish, fresh, chlorinated and unchlorinated water supplies worldwide
- Resistance to chlorine, cold temperatures
- Able to survive in polluted or poor oxygen environments
- Travels via bloodstream to the first available organ (my guess would be the swim bladder organ)
- produces Aerolysin Cytotoxic Enterotoxin [ACT]

Introduction Aerolysin Cytotoxic Enterotoxin [ACT]

The toxin binds to high- affinity receptors and undergoes oligomerization to form a heptameric pore- forming complex which allows passage of small molecules in the plasma membrane, resulting in permeabilization of the cell, cell death, and eventually tissue destruction [taken from

In English, basically the bacterium produces ACT toxin which forms polymers aka oligomerization (consists of two, three or more monomers). It means that the lining of the swim bladder organ thickened, thus interfering with the exchange of gas into the sac or reduced sac elasticity.

NOTE: A fish may use its swim bladder to move up and down in the water by taking in and release air through its sphincter (I think found the anus maybe?). That’s why swim bladder problems have three types of problems. There are Headstanders, Tailstanders, sitters and Sleepers problems.

Headstanders type are fish which ‘stand on his head’, Tailstanders type means refers to fish which are ‘sitting on his bottom or anal fins’ and lastly sleepers are to those fishes is ‘sleeping’. [Taken from http://article.discusnews.com/cat-02/swimblader.shtml ]

good readup bro, thanks for sharing

[joels]

Thanks for sharing bro

Bro .. i need the cure URGENTLY .... gum sia

Pai seh, went to the link you gave. It's in there .... but i think my fish no cure liao ... more than 5 days ...... sianzzzzzzzzzzz

Don't worry bro, my discus has been suffering this on and off for the pass month now.

All i can tell is that first u need to transfer the affected ones to a hospital tank, then try to minimise the water level. Meaning that u need to set the water as such the fish can swim just nice. This is to avoid further tiring the bladder and thus making it weaker to the virus. If u want, you can place a heater and set it to 30 degrees. But becareful when you use heater. Over heating the hospital tank can be fatal.

Have lots of oxygen by using air bubbling pump cause when u put the swim bladder problem med, it will cause the oxygen to go down.

U should add more fibres to ur fish diet. Thats why when their fishes kena the problem, they feed them with peas.

I was thinking of inject more co2 to my hospital tank.. What u guys think?

[arwen]

rockfreaks how does injecting co2 helps.. it's a wonderful article that you have shared!! many thanks

just experimenting...



cause the swim bladder organ uses buoyancy from air it gets thru the fish surrounding.. So maybe if i introduce co2 more in the tank, then maybe i can get a perfect equlibrium..

But then again, that smells a disaster since the fish will suffocate.. =/

bro latte, how's ur fish coming along??

Mine.. gone to heaven already

cause the small air bubble hose came out..
