An economical evaluation of the production of seabream (Sparus aurata) in Suez Canal Region [electronic resource]

Includes reference.

The present study investigated the effect of rearing the seabream in pond aquaculture with using artificial feeding in ponds throughout June, 2017 to June, 2018, Fingerlings of 1 g weight was stocked in pond with an area of 1 feddan and 1.25 m depth at a rate of 20000 fish/feddan in a monoculture system. Temperature ranged between 21.0 and 30.8°C; pH ranged between, 7.4 and 8.9; DO ranged between 4.0 and 5.0 mg/L and salinity, ranged between 16.0-18.8 ppt during the study. Seabream attained average final average final weight 250g/fish at harvest with an increment of 249g/fish and a daily gain of 0.46g/fish. Average survival rate was 77% and total production 3.8 ton and net production was 3.78 ton/feddan. The
results revealed that the cost of feeds accounted for the largest proportion (30.03%) of the total cost of fish production, then fingerlings (1.66%), rent and other (0.09%) and labor (30.0%). This experiment demonstrated the possibility of cultivation of Seabream as well as the higher commercial value where better net return (146250 LE /feddan) was recorded with investment return of 8.80 LE / return LE cost. The results of the study revealed that Seabream is a promising candidate for cultivating in ponds.
