Advantages |
Disadvantages |
|
Feed tray |
ration placed on a 1 x 1m or 1 x 2 m fine meshed net situated
15-20 cm below the water surface |
low cost and simple to use |
limited feed distribution; significant nutrient leaching and
feed disintegration |
|
Hand feeding |
ration broadcasted by hand for 15-30 minutes |
allows uniform feeding and observation of appetite and feed
response |
costly and labour intensive |
|
Demand feeder |
feed release mechanism triggered by fish on demand |
cost- and labour- efficient; reflects on appetite and
condition of fish |
should be used strictly with a maximum feeder: fish ratio to
ensure uniform feeding; cannot be used for smaller than 20 g fish |
|
Automatic feed blower |
feed automatically broadcasted by electrically powered feed
blower |
wide area of distribution of at least 1:5,000 feeder: fish
ratio |
does not reflect fish appetite; requires electrical power;
high cost and high power consumption (1/4-1/2 hp) |
|
Automatic feed spreader |
feed automatically broadcasted by electrically powered feed
spreader |
wide area of distribution at 1:10,000-15,000 feeder: fish
ratio; lower power consumption; certain models accepts crumbled feeds |
does not reflect fish appetite |
