3. Fishpond is an artificial body of water surrounded by dikes and with accessories such as gates, pipes and canals to facilitate water supply management.

4. In view of the high cost of fishpond development, the layout of improved types of fishponds, and the specifications for different pond designs must be simple and functional. The nature of compartments or units of a fishpond project is dependent upon the nature and quality of water supply and the species of fish to be cultivated.

6. Area= 10,000 m² NP TP = 9% of the production area RP = 1% of the total production area = 80% of the production area CP = At least 2% of the NP Other languages First languages Dutch German Russian FORMULA 7/10 3/10 5/10

7. NP = 10,000 x 1% = 10,000 x 0.01 100 m² =10,000 x 80% RP =10,000 x 0.80 = 8,000 m² CP = 100 x 2% = 100 x 0.02 =2m²

8. 333,000 Earths is the Sun’s mass 386,000 km After the proposed fishpond site is thoroughly examined and selected based on the required factors for pond selection, the following are the different compartment units, and the common accessories of the pond systems which are to be considered in making the layout plan.

9. Common Units of a Fishpond Transition pond Rearing pond

10. Catching pond Water supply canal

11. Jupiter is the biggest planet of them all Interests Mercury Nursery pond (NP)- for the rearing of fish fry to fingerlings size. The most suitable place is where it can be easily supplied with fresh, unpolluted water all the time and at elevation where it can be readily drained even during ordinary low tide. The size of the NP depends primarily on the fingerling requirements of the rearing ponds based on the maximum yearly targeted production . 2. Transition pond (TP) - for the storage or acclimatization of fingerlings. It is located adjacent to the nursery pond in order to have an effective and easy transfer of fry. Its pond bottom is constructed a little bit lower than that of the nursery pond. 3 . Rearing pond (RP) for raising fingerlings up to marketable size. It is the largest compartment in the pond system. Venus Venus is the second planet from the Sun Jupiter Saturn Saturn is composed of hydrogen and helium

12. 4 . Breeding pond -for confining breeders. 5. Hatching pond- for depositing eggs until these are hatched. 6 . Catching pond (CP) for confining and catching fry, fingerlings and fish of marketable size. It is constructed at the gate inside the pond where it is intended to be used. 7 . Head pond-for storing reserve water.

13. Career highlights 8. Feed pond- for producing food such as lab-lab, lumut or plankton. In fishpond areas where natural foods not grow well and supplementary feeding is necessary, one of the RP's or NP's could be utilized as a feed pond. It should be a separate compartment ideally located near the pond where supplementary feeding is intended. 9. Water supply canal - for supplying water to the different compartments.
