reference: Fish TuberculosisWhat few of us know, however, is that a bacterium closely related to Mycobacterium tuberculosis called Mycobacterium marinum can be present in wild caught as well as captive bred fish and stay lurking in our aquariums without us ever realizing it. After all, when one of our fishes goes belly up, few of us drag out the Petri dish and starts growing bacterial cultures to find out exactly what caused its demise.
Our skin is remarkably good at keeping malevolent microorganisms out, but as soon as the skin gets injured, an important part of the body’s defense system has been breached. It doesn’t have to bee a large wound; a simple paper cut or eczema can be enough for Mycobacterium marinum to slip through.

- Bacteria from fish and reptile pets, such as Salmonella, can cause gastroenteritis after entering our digestive system.
- Other types of bacteria can enter the body through cuts and scratches on the skin, causing a skin infection that may spread to other parts of the body.
- Common symptoms of gastroenteritis include diarrhoea, fever, stomach cramps, nausea, vomiting and headache.
- Symptoms usually last 4-7 days, sometimes longer depending on the severity.

Im not a fan of using nets to lift fish out of the water. The fins so often get caught and damaged. Catchinhg it with a net then placing it in a small container (while still under water) is a much better option. This way no hands are involved either.
Another question, or rock into the bush...
Are our nets not too harsh for some of the fish?
Example, Powder Blue Tangs are white spot magnets. Why do they get infected after being handled? They can be clean for some time, but net them, move them and viola. WS infection.
Why can WS infect the fish easier after being netted? Are we not injuring the fish with a too rough net, rubbing or exposing scales in the process. So that the WS actually get change to enter the protective coating or mucus layer on the fish.
Or am I missing something.

Hi Riaan, i do think that certain nets can harm fish and the way we handle them in and with the net also plays a big roll. I think that if you are not use to handeling fish in this way every day then you will do more harm than someone who does it often or everyday. Bottom line is that fish will be harmed when handeling but it is the amount of harm that differs depending on the experience of the person catching and handeling that perticular fish.Another question, or rock into the bush...

I like where you are going with this. I personally use hands. My fish are happy and so am I. I find that you do it gently and with nets they always seem to get stuck and you end up trying to pry them out of that and that make the transition period (the move) much longer and more stressful.
PS I am far quicker at catching a fish with my hands than with a net![]()

I also wash my hands....Come visit by me williet ... you can catch my lion .... then we'll see how fast you are ....BTW ... I have a friend of mine in Durbs that pets his lions but only on the side fins ... after being stung a few times he keeps clear of the dorsels![]()
Used a plastic cup for them since then.
