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.

200 fry of carp obtained from induced breeding by stripping were fed three times daily ad libitum with Artemia (DT1), commercial starter diet (DT2), and dried egg yolk (DT3)for  8 weeks. Each  treatments were in triplicates in indoor hatchery. At the end of the experiment, the progenies mean weight gained (MWG) was highest in the treatments fed Artemia (3.490±0.015a) as compared to others with significant difference (P<0.05).Mean weight gained (MWG) was highest in the treatments fed Artemia. Percentage weight gain (%WG) and specific growth rate (SGR) had no significant differences (P<0.05). Feed conversion ratio (FCR) was highest (P<0.05) in treatment fed with smashed egg yolk. Feed conversion efficiency (FCE) was highest (P<0.05) in the treatment fed with composed feed. Mortality rate was highest in treatment fed with Artemia, and percentage survival was highest (P<0.05) in treatment fed with composed feed. Percentage jumpers per treatment were highest in Artemia diet. In conclusion, it is imperative that Artemia feed (amidst other starter diets researched on) is most preferable for the optimum growth and development of common carp fry.

The present study aimed to investigate the effect of fish grading on the growth performance of common carp Cyprinus carpio cultivated in floating cages located in the Al-Mashab River northwest of Basrah. A total of 4896 fishes were transferred from storage cages to culture cages (3×4×2 m), and distributed at a rate of 816 fishes per cage with a culture density of 34 fishes/m3 into six cages, three of which were classified into large (GL), middle (GM) and small (GS) individuals, whereas three cages were left without grading (UG). The graded and ungraded cages were chosen depending on the standard deviation for each cage. The fishes were fed for both treatments on a standardized, locally made diet. The results of the study were evaluated according to the criteria for total weight gain (WG), daily growth rate and specific growth rate. In the first grading process, significant differences (P<0.05) were recorded between graded (GL) and ungraded in final weight and specific growth rate (SGR) but not in weight gain and daily growth rate (DGR), while in the second grading, significant differences (P<0.05) were recorded between graded (GL) and ungraded in final weight and weight gain but not in SGR and DGR. At the end of the second grading period, the daily and specific growth rate of graded fishes were ranged between 3.26-4.73 g/day and 0.22-0.46%/day, respectively, while for ungraded fishes there were 2.35 g/day and 0.23%/day, respectively. The survival rate (SR) was not different very much in all treatments and ranged between 94.34 to 95.49% in small graded and ungraded fishes, respectively. The study results recommend at least two grading processes should be established during the culture season in two or three months intervals.

Three intestinal bacteria isolates (namely C1, C2, and C3) from common carp (Cyprinus carpio) were isolated and identified as new potential probiotics. This research aimed to study the effect of three isolates potential probiotics addition on growth performance, survival rate and feed efficiency of common carp. Completely randomized design was assigned to fourth diet treatments with five replicates. As a control, we used the feed without any supplemention of potential probiotic. The result showed that the addition of potential probiotic bacteria (C1, C2, and C3) gave significant effect on daily growth rate, survival rate and feed efficiency and could be used in aquaculture industry to reduce feeding cost.

     This investigation was carried out to utilize common vetch Vicia sativa in formulating diets for 84 common carp Cyprinus carpio L. with initial weight 28±2g/fish were distributed randomly over seven experimental diets with three replications for each. The fish fed experimental diets for 56 days contained 30% and 45% of common vetch Vicia sativa of total diets which treated with germinated for 5 days (diet 2 and 3), 7 days (diet 4 and 5) and  the last diets contained crude vetch (diet 6 and 7). The statistical analysis of data showed that the fish fed at diet 3 was significantly different (P≤0.05) compared to fish fed at another diets in total weight, total weight gain, relative growth rate, specific growth rate and feed conversion ratio. It is in conclusion germinated common vetch seed can be successfully used as an inexpensive plant protein source at level of 45% (germinated seed for 5 days) in common carp diets without adverse effect on fish performance.

Growth parameters of common carp Cyprinus carpio were investigated in 13 plastic tanks (550 cm diameter and 130 cm depth) of semi-closed system at Abu Al- Khaseeb District, Basrah from 27 October to 17 December, 2016. Number of fishes in every tank was 1300 with an average initial weight 101.9 g. Fishes were fed at a ratio of 5% on sinking pelleted food manufactured in Basrah University factory with 25% protein ratio. Results of current study exhibited highest final weight (381.1 g) achieved by fishes reared in tank number 1 and lowest (326.3 g) in tank number 2. Average fish weight increments for 13 tanks were 248.2 g, with highest weight increment (266.5 g) achieved by fishes reared in tanks 6 and 11, while lowest (222.3 g) achieved by fishes reared in tank number 7. Result also appeared average daily growth of 4.87 g/day, with highest (5.22 g/day) achieved by fishes reared in tanks 6 and 11 and lowest (4.36 g/day) achieved by fishes reared in tank number 7. Average specific growth rate for 13 tanks was 2.44 %/day, with highest (3.10 %/day) achieved by fishes reared in tank number 3 and lowest (1.99 %/day) achieved in tank number 1. Average food conversion rate (FCR) for 13 tanks was 2.12, with highest (2.55) achieved by fishes reared in tanks number 1 and lowest (1.74) achieved by fishes reared in tank number 3.
