| Abstract | ||||
| The study involved cultivating 20,000 European seabass (Dicentrarchus labrax) in earthen ponds in the Suez Canal region for 540 days, with an average initial wet weight of 30g. During the study, the salinity of the water was 25.75ppt under commercial production conditions, and the water depth in the one-feddan pond at the Suez Canal Fish Farm was approximately 1.25 meters, from June 2020 to December 2021. The fish were fed an artificial diet containing 38% protein from the start of the experiment until its conclusion. At the end of the trial, the European seabass had an average weight of 225.0 ± 22.98g, with a feed conversion ratio (FCR) of 2.00 ± 0.001, and a feed intake (FI) of 4.134 tons per feddan. The specific growth rate (SGR) in weight was 0.37g/ day, and the feed efficiency (FE) was 0.5. The initial body length was 13.6cm, and the final length was 35.2cm, with an SGR in length of 0.18cm/ day. The overall production cost was 151,000 LE per feddan, and 2,067 tons of fish were produced per feddan. The findings indicated that under these experimental conditions, Dicentrarchus labrax (European seabass) can be successfully raised in earthen ponds with good growth performance, feed consumption, and net profit. | ||||
