<strong>Pangasius</strong> <strong>Culture</strong> <strong>in</strong> <strong>Cage</strong><br />
I. BRIEF DESCRIPTION OF THE PROJECT:<br />
The project is a rectangular float<strong>in</strong>g fish cage with metal frame measur<strong>in</strong>g 12m x<br />
6m. <strong>in</strong>stalled <strong>in</strong> Small Farm Reservoir or Small Water Impound<strong>in</strong>g Project (SFR/SWIP).<br />
The float<strong>in</strong>g frame is made of galvanized iron pipes jo<strong>in</strong>t together with the use of<br />
scaffold<strong>in</strong>g clamps with plastic drums (210 liter capacity) as floaters. The whole structure<br />
is anchored on at least two sides to prevent it from drift<strong>in</strong>g. The net cage is attached to<br />
the floater like an <strong>in</strong>verted mosquito net where cultured fish are stocked.<br />
The cage is made of nylon nets size 18 mesh measur<strong>in</strong>g 10 meter long by 5<br />
meters wide and 3 meters high. The customized net cage is attached to the float<strong>in</strong>g frame<br />
with at least .5 meters freeboard to prevent the stocks from escap<strong>in</strong>g. The approximate<br />
effective volume of the above mentioned cage is about 125 cubic meters.<br />
The cage is stocked with P. hypopthalmus a tropical warm water catfish, which<br />
grows to a maximum size of 8 kg. Under <strong>in</strong>tensive aquaculture conditions the species will<br />
reach harvest size of 1 kg. more or less <strong>in</strong> approximately 6-9 months. The fish are highly<br />
resistant to crowd<strong>in</strong>g and low oxygen and convert low prote<strong>in</strong> feeds. In Vietnam, much of<br />
the production is done <strong>in</strong> large float<strong>in</strong>g cages suspended <strong>in</strong> rivers, or <strong>in</strong> earthen ponds.<br />
<strong>Cage</strong> production ranges from 35 to 65 kg/m 3<br />
while pond production can exceed 35 MT/<br />
ha.<br />
To date, there are about 3,000 hectare comb<strong>in</strong>ed area of SFRs and SWIPs<br />
established <strong>in</strong> the region. These are potentials areas that can be tapped to produce<br />
alternative fish species such as <strong>Pangasius</strong>. Our fish sufficiency level regionwide is only<br />
about 65%. The demand for fish as source of prote<strong>in</strong> especially <strong>in</strong> land-locked areas is<br />
want<strong>in</strong>g. Hence, ventur<strong>in</strong>g <strong>in</strong>to other species for culture could <strong>in</strong>crease our sufficiency<br />
level and generate job opportunities and <strong>in</strong>crease <strong>in</strong>come which could support our<br />
government <strong>in</strong> the fight aga<strong>in</strong>st poverty.<br />
II. BRIEF TECHNICAL ASPECT<br />
The recommended areas to be tapped are the exist<strong>in</strong>g SFRs and SWIPs which are<br />
currently not optimized for aquaculture purposes. Water quality must be suitable for fish<br />
culture with at least 2-3 meters deep or above dur<strong>in</strong>g summer. Selected areas must be free<br />
from water pollutants and accessible by land transportation for ease of <strong>in</strong>puts delivery<br />
and movement of produced for market<strong>in</strong>g.<br />
Stock<strong>in</strong>g shall be done early <strong>in</strong> the morn<strong>in</strong>g or late <strong>in</strong> the afternoon to avoid too<br />
much stress, which may result to high mortality. Proper care shall be taken to acclimatize<br />
the newly procured f<strong>in</strong>gerl<strong>in</strong>gs from the hatchery to the temperature of the SWIP/SFR by<br />
float<strong>in</strong>g the bags <strong>in</strong> the cages for at least 15 m<strong>in</strong>utes before releas<strong>in</strong>g the f<strong>in</strong>gerl<strong>in</strong>gs <strong>in</strong>to<br />
the water.<br />
<strong>Pangasius</strong> f<strong>in</strong>gerl<strong>in</strong>gs size 14 will be fed with commercial feeds follow<strong>in</strong>g a<br />
feed<strong>in</strong>g rate of 5% of their ABW to be adjusted bi-monthly ( see below feed<strong>in</strong>g rate).<br />
Feed<strong>in</strong>g will be based on the follow<strong>in</strong>g:<br />
