“…Mirror carp (C. carpio) recorded SGR of 4.95 and 4.80 %day-1 in two densities during 90 days (Hossain et al, 2014). Taher et al (2018) revealed SGR of 2.44 %/day and FCR of 2.12 for common carp reared in semi-closed system for 52 days. Taher (2020) recorded WI of 484.5-411.4, DGR of 4.07-8.21 g/day and FCR of 2.56-7.07 when investigated four imported floating pellets.…”

The current experiment was conducted in one earthen pond (2500 m2) at Agricultural Research Station of the Aquaculture Unit, College of Agriculture at the University of Basrah, Al-Hartha District from 17 February to 10 June 2021. This experiment aims to investigate growth differences between common carp cultivated in small cages (2 x 3 x 2 meter) located inside earthen pond and those were released in the same pond. Effects of fish stocking density inside small cages were also investigated. Four stocking densities were used [100 fishes in cages 1 and 2 (T1); 150 fishes in cages 3 and 4 (T2); 200 fishes in cages 5 and 6 (T3); 250 fishes in cages 7 and 8 (T4); while 1600 fishes were stocked in the earthen pond (T5)]. Fishes were fed daily 3% of fish weight on commercial sinking pellets manufactured by Agricultural Consultant Office of the College of Agriculture. Total length and weight of fishes were measured at the beginning and at the end of the experiment, while subsamples of fishes were weighed periodically and daily feed changed after each weighing. Daily feed was divided into three meals, the first one was given early at the morning, the second one at mid-day and the third one at afternoon. Results of current experiment revealed best growth criteria in T1 where average final weight was 750.5 g, average weight increment was 454.6 g, average daily growth rate was 4.33 g/day and average feed conversion rate was 2.77. Some of these criteria showed significant differences (P≤0.05) between T1 and other treatments, while feeding conversion rate (3.33) was achieved by fishes reared outside cages in the pond. As a conclusion, it can be pointed out that growth criteria of fishes reared inside cages were better than fishes reared outside cages and fish stocking densities were not affecting growth criteria of fishes reared inside cages.

“…Enache et al (2011) recorded 1.07 %day -1 as specific growth rate and 1.49 as feed conversion rate of common carp cultivated in RAS for 30 days. Common carp showed specific growth rate of 2.44 %day -1 and feed conversion rate of 2.12 when reared in semi-closed system for 52 days (Taher et al, 2018). Coroian et al (2015) stated that life food had positive effects for growth of common carp fingerlings comparing with traditional feeds.…”

A comparison was conducted for growth criteria of common carp, Cyprinus carpio larvae cultivated in earthen ponds and recirculation aquaculture system (RAS) depending on live foods (phytoplankton and zooplankton stimulated by buffalo fertilizers in earthen ponds, while the larvae cultivated in RAS were feed on Artemia larvae reproduced in vitro, in addition to manufactured pellets (38% crude protein) for common carp in both systems. Three 2500 m2 earthen ponds were cultivated for 90 days with larvae of initial weight 0.002 g at different numbers (40800 larvae for pond 1, 55600 larvae for pond 2 and 36400 larvae for pond 3). These larvae depend on natural food for 19 days, then fed on manufactured feed. Fishes were weighed every 19 days to change daily feed. Three replicates of RAS plastic tanks (100 letter capacity) cultivated for 90 days with 0.002 g larvae at a density of 2 larvae per one liter (160 larvae at each plastic tank). These larvae fed for 15 days to saturation (4 meals daily) with Artemia larvae and small Artemia, then fed on manufactured feed. Subsequently, fishes were weighed every 15 days to change daily feed. Larvae cultivated in earthen ponds recorded weight gain of 26.90 g, daily growth of 0.30 gday-1, relative growth of 1345000%, specific growth of 10.56 %day-1, feed conversion of 1.25 and survival rate of 13.16%. Larvae cultivated in RAS system recorded weight gain of 1.53 g, daily growth of 0.02 gday-1, relative growth of 76200%, specific growth of 7.37 %day-1, feed conversion of 2.82 and survival rate of 72.32%. Statistical analysis of results revealed significant differences (p>0.05) in all growth criteria for larvae cultivated in both systems. Final conclusion that earthen pond was better than RAS systems in producing fingerlings of common carp.

The experiment was conducted at Agricultural Research Station- Aquaculture Unit- Agriculture College- Basrah University in six earthen ponds (600 m3). The stady inclouding of alien organizms effect on growth of common carp Cyprinus carpio. Using an agricultural shadow as a filtering fabric was put in inlets pipes (T1), while T2 without filters. Fishes was daily feeding by a commercial sinking pellets manufactured by Agricultural Consultant Office belonging to Agriculture College, With a ratio of 3% from fishes weight. Total length and weight of fishes were measured at the beginning and at the end of the experiment. The weight of subsamples for fishes were taken periodically and daily feed changed after each weighing. At the end of the experiment the alien organism in all ponds were collected, classified and weighed individualy except shrimp. Results of current experiment revealed that there were significant differences (P≤0.0.5) in final weigh, wight increment, daily growth rate and feed conversion rate between fishes reared in ponds with and without filter. These differences may be related to differences in numbers and weighs of alien organisms in these ponds (97 individuals of six fish species in ponds without filter comparing with two individuals of one fish species in ponds with filter, and also 16314 g of shrimp in ponds without filter comparing with 440 g in ponds with filter). From the results of the current experiment, it can be concluded that culturist must used filters in inlet pipes of their ponds to prevent or reduced the entering of alien organizms to these ponds.
