Technique | (i) High Speed Wave |
(ii) & (iii) Low Speed Wave | |
- Pole to tide the cage | |
- Hut at the centre of the project | |
- Water breakers - High speed wave | |
- Float - 7 gallon or 44 gallon of | |
plastic drum | |
- Wood - Chengal Batu | |
Net | 3–5 Category (i) - 3/8" |
(ii) - 1/2;" | |
(iii) - 1" | |

VII. Economic
(A) CAPITAL
1. | Cost of cage | - Frame | $2,500.00 | |
Net | 1 Unit | |||
Anchor | 4 Unit/cage | |||
Float | ||||
2. | Cost of fry | - Seabass | $1,000.00 | |
- 1 Fry = 50¢cents | ||||
- 2,000 Fry = $1,000.00 | ||||
3. | Cost of feed | - Stocking 2,000 fry | $2,688.00 | |
80% Survival Rate = 1,600 Fish | ||||
1 Fish = 600 gm | ||||
1,600 Fish = 960 gm | ||||
F.C.R. = 7:1 | ||||
.. 7 × 960 = 6,720 kg | ||||
1 kg = 40 ¢ | ||||
.. 6,720 kg = $2,688.00 | ||||
4. | Contingencies - $1,000.00 | |||
e.g. | - Fuel | $1,000.00 | ||
- Container | ||||
- Scoop Net | ||||
- Weight machine | ||||
“Not include labour charge” | ||||
Total Cost | $7,188.00 |
(B) INCOME
1 Kg = $10.00 | $9,600.00 |
960 Kg = $9,600.00 | |
Gross Income | $9,600.00 |
Net Income | 2,412.00 |
