Abstract
SUMMARY AND CONCLUSION
This experiment was conducted in the project closed systems for fish
farming - Faculty of Agriculture - Ain Shams University - Shubra Al
Khaimah - Cairo - Egypt, and designed this experiment to investigate the
effect of farming different densities of fish Nile tilapia and plants bots
together in a closed system under the conditions of the closed system is
Experience on May 15 and ended on the seventh of September 2010 test
period lasted almost 116 days, where the transactions are: 25 tilapia fish
with the 8 plants Pothos, 50 tilapia fish with 8 plants Pothos and 75 tilapia
fish with 8 plants Pothos.
Experience Design:Used in the experiment twelve Basin Fiberglass circular dimensions (60 cm high × 81 cm radius) representative of three transactions in each treatment three replicates and treatment comparison has designed the
experiment in the sectors of simple fully randomized in three replicates,
and the average weights fingerlings in ponds (35.65 g) at the beginning of
the experiment. The first treatment:
Nile tilapia fish density in the pelvis (25 tilapia fish + 8 Pothos plants) for
the duration of the experiment.
- Second treatment:
Nile tilapia fish density in the pelvis (50 tilapia fish + 8 Pothos plants) for
the duration of the experiment.
- Third treatment:
Nile tilapia fish density in the pelvis (75 tilapia fish + 8 Pothos plants) for
the duration of the experiment.
-Study productivity:
The aim of this experiment is to determine what equations (25 tilapia
fish + 8 Pothos plants), (50 fish tilapia + 8 Pothos plants), (75 fish
tilapia + 8 Pothos plants).
gave the highest purity water basin.
During the experiment was to assess the quality of water fish in terms of:
pH water Aquarium Nile tilapia - water temperatures Aquarium Nile
tilapia, as well as been estimated concentration of nutrients in the water
Aquarium Nile tilapia and these elements are: a nitrogen element
phosphorus, element potassium, calcium, element magnesium, nitrate,
ammonia.Upon completion of the experiment following measurements were
recorded on fish: average daily gain - the average increase in weight -
specific growth rate - the rate of feed conversion - vital fish. And
recorded the following measurements on crop plants at harvest time:
number of leaves per plant plant height (cm) the total weight of fresh crop
g/m2 - total weight dry crop g/m2, and also has been estimated
concentration of nutrients for Potts and these elements are: a nitrogen, the
phosphorous, potassium, calcium, element magnesium.
Summarized the most important findings of the study are as follows:
That the transaction (comparison 25 fish) recorded the best results in the
weighted average increase in average daily gain and also said the results
were recorded the same treatment (comparison 25 fish) in conjunction
with transactions (comparison 50 fish) and (25 fish treatment) in specific
growth rate and For feed conversion rate showed (comparison 75 fish) is
highest in the transaction while (25 fish treatment) gave the highest rate
of vitality. The results showed that treatment (treatment 50 fish) produced
٥۷
the highest height of the plant and the highest yield, while treatment
(treatment 25 fish) was the largest number of securities plant and in terms
of the estimates chemical plant bots recorded treatment (treatment 25
fish) the highest concentration of the element nitrogen while the treatment
(treatment 75 fish) recorded the highest concentration of both of
Annasraltalah: phosphorus, potassium, calcium and (50 fish treatment)
recorded the highest concentration of the element magnesium while
showed treatment (comparison) the highest content of chlorophyll.
Inferred from this study include:
This system is working to increase the final weight of the Nile tilapia,
Integrated aquaculture system consider a useful system particularly in arid
land, it’s provide with safety plants and fish without water loss and
produced two kinds products with high quality
