  • PFNCS is the most basic facility in aquaculture activity. The features in PFNCS will greatly affect the growth rate of fish and fish quality. The basic features required from the PFNCS are: - Environmentally friendly.
  • the environmentally-friendly PFNCS will provide good aquaculture condition and improve the growth rate of fish, the quality, and the price of farmed fish that leads to the: increase in the value of the aquaculture activity itself.
  • the ease of assembling and disassembling the PFNCS will reduce the PFNCS transportation and installation cost at the aquaculture site, and will allow the fish farmers to relocate, to modify the configuration, or to expand the PFNCS in optimizing the value of aquaculture activity.
  • the optimation of aquaculture activities requires an adjustment to the shape and dimension of PFNCS utilized.
  • the adjustment to the shape and dimension is owing to the habits of each different aquaculture commodities. For instance, "fast swimmer” fish need large farming site in order to swim freely like in the ocean. By placing the "fast swimmer” fish in large PFNCS, the growth rate of fish will be more optimal and allows the fish farmer to reduce costs and risks as well as to accelerate the capital turnover.
  • Multigonal Knock-down Polyethylene (PE) Floating Net Cage System and Method of Manufacture Several reasons for choosing Multigonal-shaped PFNCS is closely related to the advantages acquired from the shape, which are:

  • Multigonal PFNCS has some advantages compared to rounded FNC which is made using a butt fusion methods as follows:
  • Multigonal PFNCS consists of components that may be assembled and disassembled at the installation site without electrical tools, while the butt fusion rounded FNC requires a large area, pulling truck, and electrical tools in order to assemble at the cultivation site and cannot be reassembled.
  • Multigonal PFNCS has floating devices which are separated from each other so that if damage occurs to one of the floating device, the affected floating device can be removed and replaced without affecting the other floating devices.
  • ⁇ the butt fusion rounded FNC has one integrated floating device that if damage occurs, it may ruin the whole set of FNC.
  • I section of floating device in Multigonal PFNCS may be disassebled to allow ships to enter the Multigonal PFNCS and perform the proses of net replacement or harvesting.

SYSTEM AND METHOD OF MANUFACTURE
Field of the Invention
The present invention generally relates to a Multigonal Knock-down Polyethylene Floating Net Cage System [PFNCS] and method of manufacture, more specifically, the present invention relates to polyethylene floating net cage system having at least 8 [eight] angles for one cage assembly opening, then combined with other floating net cage assembly openings to be assembled with each other forming a cage assembly configuration consisting of several openings and the method of manufacture.
Background of the Invention
For the information, the present application is an improvement from prior patent applications, namely Patent Application No. POO 2009 00257 filed on May 04, 2009; S00 2009 00139 filed on July 13, 2009; POO 2009 00480 filed on August 31, 2009; P00 2010 00291 filed on April 22, 2010; and P00 201 1 00079 filed on January 27, 201 1 and many other patent applications which are not stated herein.
In fish farming (aquaculture) activities, either in sea water or in fresh water, the aquaculture facility utilized is Polyethilene (PE)-based Floating Net Cage (FNC).
PFNCS is the most basic facility in aquaculture activity. The features in PFNCS will greatly affect the growth rate of fish and fish quality. The basic features required from the PFNCS are: - Environmentally friendly.
The environmentally-friendly PFNCS will provide good aquaculture condition and improve the growth rate of fish, the quality, and the price of farmed fish that leads to the: increase in the value of the aquaculture activity itself.
- Easy to assemble and dissassemble (completely knock down).
The ease of assembling and disassembling the PFNCS will reduce the PFNCS transportation and installation cost at the aquaculture site, and will allow the fish farmers to relocate, to modify the configuration, or to expand the PFNCS in optimizing the value of aquaculture activity.
- Durable.
The durability of PFNCS wi ll reduce the FNC maintenance and supply costs.
In a more detailed discussion, in addition to the abovementioned basic features, the optimation of aquaculture activities requires an adjustment to the shape and dimension of PFNCS utilized. The adjustment to the shape and dimension is owing to the habits of each different aquaculture commodities. For instance, "fast swimmer" fish need large farming site in order to swim freely like in the ocean. By placing the "fast swimmer" fish in large PFNCS, the growth rate of fish will be more optimal and allows the fish farmer to reduce costs and risks as well as to accelerate the capital turnover.
In optimizing the farming activities of "fast swimmer" fish, a large PFNCS with low cost is required. This may be accomplished by constructing nearly-circular shaped PFNCS, i.e., "Multigonal Knock-down Polyethylene (PE) Floating Net Cage System and Method of Manufacture". Several reasons for choosing Multigonal-shaped PFNCS is closely related to the advantages acquired from the shape, which are:
Multigonal PFNCS has the basic features which are highly needed in optimizing the cultivation activites, which are environmentally friendly, completely knock down, and durable, as well as:
1. The multigonal shape is an efficient nearly-circular (semi -circle) shape, can contain a very large area allowing vast volume of water with the smallest number of floating device possible.
2. Multigonal PFNCS allows the application of linear floating device. By modifying the length of floating devices used, the diameter of Multigonal PFNCS can be modified, and even allows making long Multigonal PFNCS.
3. Multigonal PFNCS may be connected with similar PFNCS in four directions so that it facilitates easy monitoring and expansion.
4. The application of Multigonal PFNCS shall provide oxygen reserve to the cultivated fish by leaving a square shaped space between FNC openings.
5. Joint cube (a connector for Multigonal PFNCS) is located immediately above the water surface, providing the Multigonal PFNCS with many lines for oxygen inflow on water surface into the cultivation area through under joint cube. This will improve the oxygen circulation for the cultivated fish.
6. In the case of assemble and disassemble, Multigonal PFNCS has some advantages compared to rounded FNC which is made using a butt fusion methods as follows:
a. Multigonal PFNCS consists of components that may be assembled and disassembled at the installation site without electrical tools, while the butt fusion rounded FNC requires a large area, pulling truck, and electrical tools in order to assemble at the cultivation site and cannot be reassembled.
b. Multigonal PFNCS has floating devices which are separated from each other so that if damage occurs to one of the floating device, the affected floating device can be removed and replaced without affecting the other floating devices. On the other hand^ the butt fusion rounded FNC has one integrated floating device that if damage occurs, it may ruin the whole set of FNC.
c. In the condition of harvesting or net replacement, I section of floating device in Multigonal PFNCS may be disassebled to allow ships to enter the Multigonal PFNCS and perform the proses of net replacement or harvesting.
Considering the abovementioned matters are very important in aquaculture, the inventor creates a knock-down polyethylene floating net cage [PFNCS] as required for the knock-down polyethylene floating net cage discussed above.
