These fish could be saved-MALAYSIA - A total of 117 caged-fish breeders of Sri Tujuh lagoon lost almost RM500,000 when their fishes were found dead earlier this week

We (MY COMPANY-NATURAL SYSTEMS) first got the idea from a paper written by a Mr. Dahmer a researcher in the oil recovery business who explained in a trade publication how they had devisd a u-tube to dissolve air(all the gases including nitrogen, oxygen and carbon dioxide) in water and then inject the super saturated water under oil rich shale. the dissolved air would fizz off as tiny bubbles that would bubble up under the shale pushing the oil ahead, thereby helping to recover more oil from areas that were previously pumped out.

Our first question to him was would a similar setup or process allow us to dissolve pure oxygen (without the nitrogen being dissolved) in the water, and if so just how much oxygen could be dissolved. Mr. Dahmer did not know because he had never tried it, but said that we wanted to, we should try it and see how it works.

We decided to move forward in this, and as I had sufficient money from our large Mexico contract and we drilled a hole 4 inches in diameter in the ground just out side of our greenhouse that was 35 feet deep. I had already arranged to have a large tank of liquid oxygen placed on our property and installed a number of other systems to find the best way to get the most oxygen to our tilapia.

We then took a 3 inch piece of PVC pipe, glued a cap on what was going to be the bottom and dropped the pipe to the bottom of the 35 foot hole. then dropped a second piece of 2 inch diameter pipe and dropped it in until it rested on the bottom of the 3 inch piece of pipe then glued a 3 inch T on the 3 inch pipe. We left a few inches of 2 inch pipe sticking out of the top of the 3 inch pipe. We then took a 2 inch by 3 inch reduction fitting and carved out the PVC retaining ring in the two inch part of the reduction fitting so the ring reduction fitting allowed the two inch pipe to be slid up enough to raise it 2 inches off the bottom and we then glued it so that it was held up off the bottom while it was working. We the hooked it up so that we were bringing tank water to be sent down the utube with a measured amount of oxygen so that we were able to get 35 to 40 ppm going into a tank.

I got a consultation to design an intensive tank in Guadeloupe

for a nursuryman who decided he wanted to get into the tilapia business so I designed a complete system using all of the automated oxygen systems which would monitor the oxygen in the growing raceway, going down the u-tube, an coming out of the utube. I had the gentleman dig the hole for a u-tube 300 feet deep and when we dropped the pvc pipes and hooked it up and tested it the water coming out of the u-tube was over 300 ppm and so delivered approximatly one pound of dissolved oxygen per minute and so had plenty of oxygen to match the feeding rate of the tilapia, pound for pound..

From this success I have been able to calculate how much oxygen can be dissolved very cheaply to match the oxygen beig demanded by the tilapia and other organisms.

This U-tube system can be designed to meet almost any oxygen demand needed to keep tilapia lively, and hungry and growing under almost any conditions.

MIKE SIPE

I am 70 as of August 4th 2010.  I have spent over 41 years Breeding tilapia, improving tilapia gene lines creating Red tilapia, and improving the body form of "pennyfish" from 24% in 1963 to 50% in 2009. I have pioneered and installed high oxygen intensive aquaculture production  systems.   We (TILAPIA AQUACULTURE INTERNATIONAL) built the first u-tube used to control oxygen and co2 levels in aquaculture.   We can dissolve up to  800 parts per million parts of water and thereby control oxygen levels in growing situations. ( THIS IS WHAT MAKES OUR INTENSIVE CULTURE SYSTEM WORK SO WELL) We have designed hatchery systems to produce thousand of pennyfish fingerlings a day using breeder cages.   We have helped to establish the production of over two billion pounds per year of our tilapia in over 50 locations in North America, Mexico, South America, Central America, Kenya Africa, and Saudi Aribea in the Middle east.  Our goal is to help people with the production of tilapia necessary to *feed everyone* in the world a well balanced nutritious* diet, and to restore the forest of the world. If you wish to talk with me my phone number is 877 217 7006. Please feel free to call me during normal Eastern daylight times. At this particular time I believe that I have more hands on experience in building , designing and running u-tubes to lower the cost and risk for growing all kinds of Aquaculture by 10% - 20% and the cost of dissolving oxygen in an intensive system by 50- 85%. The safety issue is by far the most important issue because having complete control over the oxygen level in a tank helps to assure he safety of the crop and the cost. Another area where I have extensive experience is on what is required to create new characteristics in a gene line. We can take a tilapia that is black and turn it to a brilliant red or take a gene line and select for various body form changes or various internal genetics needed needed to manufacture certain expensive biochemical products..such as Heparin which is an important molecule in haemoglobin that plays a role in clotting blood. A good breeding and selection system could virtually increase the production of almost any biological chemical system in the tilapia.
