I wish to enquire about the requirements for one to get certificate for supplying and producing fingerlings. What does one needs to have. I'm a Kenyan from siaya county bondo sub County from nyangoma division That as I a wait for your response.

We will apply the remedies as suggested. Is there an easy way to determine when water is super saturated with gases? Regard Ipade well, you can add supersaturation of carbon dioxide if you are using borehole water. We can visually see the gas bubbles when dissolved CO2 is the problem. Remedy is to greatly aerated or agitate the water to drive it off. The supersaturation of gases in general can occur from a leaky intake from a pump so that there is some suction of air followed by pressurizing. Remedy for this is to fix the faulty intake. that means supersaturated oxygen. This is rarely a problem but I have indeed seen problems from levels of oxygen that approach 250-300% saturation. Remedy for this is same as the supersaturated CO2. Agitate to drive off the excess. can supersaturate the water with gases. It cannot if the water is not in a sealed container. So, in a tank that doesn’t have a closed cover, the aeration can only de-supersaturate the water. saturated with oxygen to warm water, the gasses in the blood come out of solution and form bubbles in gill filaments and elsewhere. That is one reason why it is advised to acclimate the fish when changing temperatures. Clarias are very sensitive to abrupt temperature changes. mailto:sarnissa-african-aquaculture@lists.stir.ac.uk &lt;sarnissa-african-aquaculture(a)lists.stir.ac.uk&gt;&gt; &lt;ipade(a)fingerlakes-ng.com&gt;&gt;m>>, sarnissa-african-aquaculture(a)lists.stir.ac.uk <mailto:sarnissa-african-aquaculture@lists.stir.ac.uk &lt;sarnissa-african-aquaculture(a)lists.stir.ac.uk&gt;&gt; with ornamental fish both small one and even bigger ones. From my small experience, the most probable reason is the super saturation of air in the water and especially if the water source is from a pipe with high pressure within the pipe or high level of algae in the water and increased water temperature. I have lost both catfish fry and also blackmoores, koicarps, shubunkins and even comets.

We have checked our water parameters and all seem within acceptable ranges. We do not see anything obvious with the naked eye on the dead fingerlings. However we viewed some of the live fish under the microscope and we noticed the bumps/bubbles that can be seen on the attached pictures. We are not sure whether this is the cause of our mortality, however we are going through the process of elimination. about? <IMG-20150513-WA0015.jpeg><IMG-20150513-WA0014.jpeg><IMG-20150513-WA0013.jpeg> <IMG-20150513-WA0014.jpeg><IMG-20150513-WA0013.jpeg><IMG-20150513-WA0015.jpeg>
