| Abstract | The study on productivity of, and fouling control in, hap a-based seed production of
the Thai red tilapia ( Oreochromis niloticus x Oreochromis mossambicus) was investigated in
a series of three experiments. The first and second experiments were concerned with
biological control of fouling on tilapia spawning hapas. An initial experiment compared the
use of suckermouth catfish, sex-reversed red tilapia, sex-reversed Nile tilapia, cherry snail
and pond snail as the organisms of choice for the control of fouling in aquaria. The second
experiment compared the three most promising organisms in fed and unfed spawning hapas
stocked with Thai red tilapia. Significant differences in fouling control and seed productivity
were found. Suckermouth catfish controlled fouling the best but seed production was
reduced. Cherry snails in fed hapas showed significantly higher total seed production than
red tilapia. Tilapia broodfish in hapas with cherry snails spawned significantly better and
earlier. Control hapas were significantly more fouled than those stocked with red tilapia or
suckermouth catfish, but seed production was higher. In a third experiment (84 days), the
spawning performance of the Thai red tilapia and the Nile tilapia, Chitralada strain, were
found to be similarly low (4 fry/m2
/day) and there was little effect of interharvest interval of
the two species. |
