THE USE OF STRAWS AND HAY FOR ENABLES OF THE SURVIVAL PERCENT AT CTENOPHARYNGODON IDELLA ALEVINS
Keywords:
straw and hay, Ctenopharyngodon idella, survival percentAbstract
The use of hay or straws as developing source for plankton ensures a higher
survival percentage of the fish of alevins to fry basins than the classic system. Hay
or straws are placed in basins in stacks of 15-30 kg and are covered in water in a
percentage of 75%. The experiment was carried at the Chiochis acvcultural farm
in two basins of 0.25 ha each. The basins were populated with 200,000 and at the
end of the experiment the survival percentage in the basin with hay was 36.15% as
compared to the 6.7 percentage obtained in the basin without hay. The average
weight of the samples in basin 1 was of 3.65 g/sample as compared to 1.8g/sample
in the other basin. The objective of the study was to point out that, the use of
environmentally friendly methods of growing plankton ensure the larvae a higher
survival percentage and better weight gain in their first development stages.
