FISH FARMING IN TAGBAC/TANGAL - LUBANG ISLAND

The fish farms in Tangal are generally not mechanised to any significant extent

The supply of nutrients for fish stock is largely dependant on tidal flows. A large portion of the fish farms are operating on what was formerly mangrove swamps.

The use of tidal flows for nutrients, avoids the application of costly fertilisers, which would be in any case mostly carried away by the tides.

To restock the ponds, with prawns for example, reliance is put on trapping prawns in water flowing in from the mangrove swamps.

The optimal design for a fish pond appears to incorporate the following principles:

* Be 0.5 to 1.0 metres at the shallow end, and in the range of 1.5 to 2.0 metres at the drain end.
* It should be possible to drain the pond within three days.
* Pond edges have a slope of 2:1 or 3:1 on all sides.
* Advantage taken of the wind to mix the water and aerate it.
* To avoid erosion of dikes at windy sites the long side of the pond put at right angles to the prevailing wind's direction.
