HOT SPRING NILE TILAPIA FATTENING |
| description |
In the present work, the feasibility of fattening Oreochromis
niloticus specimens on a pilot scale in a geothermal water
resource located in the Southeast of the province of Buenos
Aires was analyzed. Before placing the culture units, physical
and chemical characteristics of hot spring were studied to
evaluate its suitability for tilapia farming. In the experimental
stage, two hundred specimens with an average weight of 14.5
± 1.8g were placed in two floating cages (1.30x1x1m) (100
individuals per cage) and they were harvested at 140 days.
The specimens were fed 3 times a day with a commercial
pelleted feed with a content of 35% of proteins. Monthly
samplings were carried out to evaluate growth (weight and
total length), survival, and water samples were collected to
measure their physical-chemical characteristics. The results of
the water analysis showed a high quality in the hot springs
(Simplified Water Quality Index=88). The fattening results
showed an average final weight of 423-435.9 g, a survival of
87-91%, SGR 1.47- 1.49%/day and the FCR was estimated at
1.05-1.07 for each cage respectively. We can conclude that this
hot spring has the necessary water conditions to obtain
excellent weight gains during the fattening period for the O.
niloticus specimens. The present study represents the first Nile
tilapia culture in the southernmost thermal waters, setting a
precedent for future ventures in the area. |
