3. Preamble to the Description: Complete Specification Summary:

In this method of invention proven sterilization methods which are having certain limitations in addressing wide range of microbes, virus infections are arranged in a unique design to maximise sterilization ability of the proposed instrument. The instrument is source specific and a hybrid technology which blends pulsed UV which has variable frequency adjustment facility, pulsed UV laser at a specific wave length of 1082 ran to 1084 ran to optimize the half life of ozone gas along with ultra sonics at different frequencies and micro waves at different frequencies.
In aqua culture, various phases right from nursery to post-harvest storage and logistics depending on the types of bacterial load and viral infection proposed hybrid disinfection technology desing will be determined and optimized to deliver high performances. The uniquness of the system is the design varies depending on the target area and constituents of target species.

Benefits:

The benefits of hybrid technology are as follows:

1. Sterilization of hatchery

2. Increases immunity of the embryo thereby increases the productivity

3. Sterilization of nursery pond

4. Sterilization of grow out pond

5. Post-harvest treatment enhances the shelf life

6. Increased shelf life during transportation

4. Description

In aqua culture i.e. growing of marine and fresh water fishes, prawn cultures, post-harvest preservation and storage is a major problem faced by the cultivators across the globe. Due to massive expansive of aquaculture and mindless utilization of vari¬ous processed feed utilization are responsible for, chemical traces findings in marine foods and causing several severe health hazards and complete rejection from testing authorities. Though chemical sterilization methods are under practice they are intern imparting chemical bi products adding fire to fuel. The present invention is a solution for above said problems by providing a chemical free total sterilization effective method, yet highly inexpensive in terms of commercial calculations

Background of Invention

Pollution: While many aquaculture systems are closed with no harmful output, open net cage fish farms and land-based fish farms can discharge significant amounts of wastewater containing nutrients, chemicals, and pharmaceuticals that impact on the surrounding environment. For example, the nutrients in unused fish feed and fish faeces can cause local algal blooms, or eutrophication. These blooms lead to reduced oxygen in the water, which in turn can lead to the production of ammonia, methane, and hydrogen sulphide, which are toxic to many aquatic species. Reduced oxygen can also directly kill marine life. In addition, a wide range of chemicals is currently used in the aquaculture industry, mainly pharmaceuticals such as antibiotics and anti-fouling agents such as copper. Some of these chemicals are toxic to molluscs and crustaceans, and little is known about their broader ecological implications. In some areas, such as Southeast Asia and South America, frequent use of medications has led to increased resistance of the target pathogen to treatment.

Water Pollution: Water pollution concerns include the following:

o excess food;

o feces;

o cage materials; and,

o Antibiotics/other cleaning/algal growth prohibiting chemicals.

Water flowing out of an aquaculture facility can carry excessive nutrients, particulates, bacteria, other diseased organisms and polluting chemicals. These may harm surrounding habitats, cause algal blooms, poison ocean wildlife and other severe disturbances. Feed and faecal matter from aquaculture facilities can deplete the dissolved oxygen concentrations within and around the site. Since different fish have varying tolerances to dissolved oxygen levels, the wastewater being discharged from an aquaculture operation may have large impacts outside the facility long before a problem is detected within. Anti-fouling agents used to keep cages/pens clean are highly toxic. For example, the common anti-fouling agent butyltin (specifically tributyltin) has been linked to reproductive problems in gastropod molluscs (i.e. whelks and abalone) and is suspected to cause immune suppression in marine mammals including dolphins, seals and sea otters.

Parasites and diseases: The migration of wild salmon between fresh and salt water normally keeps sea lice, a salt-water parasite, at bay. Farmed salmon spend all year in coastal areas, which increase their chances of getting parasites. More fish farms mean more hosts for parasites - indeed; sea lice numbers are now significantly higher as a result of the millions of farmed fish in the sea. Just 10-15 sea lice can kill a fish. Wild fish can also be exposed to viruses and other diseases through the use of imported, unprocessed fish to feed farmed fish. This problem is particularly associated with farmed tuna, which are usually fed whole fish rather than processed fish pellets.

Human Health Concerns: Studies indicate that farm-raised fish contain higher levels of chemical pollutants than wild fish, including PCBs, which are known carcinogens. This is due to higher concentrations in the fish feed. Antibiotics are also a problem with farm-raised fish, effecting consumers directly as well as by developing super strains of bacteria that are resistant to antibiotics, making diseases less treatable, and perpetuates the cycle of increased antibiotic use.

Description of Invention

The "Hybrid Technology" will be applied in all stages of the fish and prawn culture such as hatchery, nursery, grow out, feed sterilization, post-harvest sterilization and transportation. The hybrid technology includes ozonisation, pulsed ultra violet, pulsed ultra violet laser and ultra sonic. Hatchery, Nursery and Grow out pond: During this phase the hybrid technology can drastically reduce the microbial contamination and improve the immunity of the embryo. Post-Harvest treatment: After the harvest, the produce will be treated with ozonisa-tion, pulsed ultra violet, pulsed ultra violet laser and ultrasonic to enhance the shelf life. Also, during transportation, along with ice box, the fish and prawns will be supplied with ozone and pulsed ultra violet to increase the shelf life.
