| Abstract | ||
| The investigation's primary goal was to determine whether it is possible to raise the gilthead seabream (Sparus aurata) and European seabass in private earthen ponds. In this study, 22,000 gilthead seabream and European seabass, each weighing an average of 10g, were raised for a full year in the Fish Farm's one-feddan pond, which has a water depth of approximately 1.50 meters. The fish were fed an artificial diet consisting of 45 percent protein, and their final body weight was 200 ± 6.14g with a weight rise of 190g, while the gilthead seabream reached 230 ± 8.24, with a weight gain of 220g. For the seabass and seabream, the daily weight gain was 0.52 and 0.60, respectively. Moreover, the SGR was 0.63 and 0.83g/ day, respectively. Seabass and seabream had respective production costs of 146,192 and 159,180 LE/feddan, total production of 2.200 and 3.036 tons/feddan, total income of 330.000 and 485.760 LE/feddan, net return of 183,808 and 326,580 LE/feddan, and investment return of 1.26 and 2.05 LE/feddan. Compared to the seabass raised in clay ponds during this experimental investigation, the seabream demonstrated superior growth performance, feed consumption, and profit. | ||
