Fish fry transport is a very important part of aquaculture. Hydrogen peroxide is generally used in aquaculture as an immersion treatment against many different disease-causing organisms, including external parasites, bacteria and fungi, on different species and life-stages of fish. In the present study, the release of oxygen from hydrogen peroxide was assessed using the Winklerís technique. This technique is simple and cost-effective for transporting fingerlings using oxygen derived from hydrogen peroxide. Glass pieces were used, which gave good results for producing oxygen from the H2O2. The present findings showed that the fishes survive more time in the H2O2-treated water than the control. From the present investigation, it can be concluded that it would be possible to transport tilapia (Oreochromis niloticus) fingerlings using H2O2 as an oxygen source.

 
 
 

Hydrogen peroxide is commonly used as a disinfectant for cleaning wounds in people. It has also been used in aquaculture as an immersion (bath) treatment against many different diseasecausing organisms, including external parasites, bacteria, fungi, different species and lifestages of fish. Hydrogen peroxide has numerous nonmedical and medical uses because of these properties. When added to water, hydrogen peroxide breaks down into oxygen and water over time, and the formation of these byproducts is one reason that hydrogen peroxide is considered to be relatively safe for the environment. The US Food and Drug Administration (FDA) recently approved a hydrogen peroxide-based aquaculture product, which has spurred greater interest in its use (Yanong, 2008).

A major challenge facing aquaculture development today is that of ensuring a sustainable fingerlings production and distribution system. It is a chronic problem with several important dimensions: quantity of fingerlings produced, quality of fingerlings produced, cost of fingerlings produced and means of fingerlings distribution to farmers (FAO, 2000). In the aggregate, these factors created a ‘scarcity syndrome’ and have led to a situation where farmers throughout the area have been forced to wait long periods before receiving scarce fingerlings, sometimes abandoning their ponds in the interim. Moreover, when fingerlings arrive, they are often of poor quality, leading to disappointing harvests and abandonment of fish ponds.

Fish fry transport is a very important part of fish culture. Fry and fingerlings must be transported from hatchery to pond for stocking. Brood fish are sometimes transported to the hatchery to spawn. It may even be necessary to transport live harvested fish to the market for sale. Many methods of fish transportation are being used by the fish farmers. Fish are generally transported in containers such as cane of different size, pots of ceramic or metal, wooden or metal baskets, vats, barrels, bags, styrofoam boxes, bottles, jugs, animal skins and bamboo section. In fact, clean and waterproof container may be used. Certain containers provide good insulation from heat, for example, wood or styrofoam. Containers like metal or plastic are poor insulators and may have to be wrapped with wet towels or packed with ice to keep temperature down. Once fish have been placed in their transport container, they should be brought to their destination by the quickest possible means that will provide a relatively smooth and direct route.
