seed provided by CP or Kaset Samboon Farms which charged almost
twice the price. When nursery ponds were used, the number of
individuals transferred to grow-out ponds was significantly correlated
to stocking density in the nursery pond (slope = 0.580, pb0.05,
R
2
= 0.606). However, the proportion that survived was not related to
initial stocking density in the nursery pond. The average proportion of
prawns that survived to be transferred was 63% (Table 4).
Once prawns were stocked they were most commonly fed with
commercial feed consisting of 40% crude protein, 15% water, 5% fat, 3%
fiber, and 1% phosphorus. Feeding trays were utilized by many farmers
as well as broadcasting feed from the dyke or from a boat. The
majority of farmers (94%) used their own judgment to modify feeding
rates by checking the remaining feed in the feeding tray or on the
pond bottom, rather than following a feeding table. Average feed
conversion ratio was 2.1 and was not related to feed type, commercial
or homemade.
