“…Azad et al (2021) described the condition factor of prawn using the same probiotics only at the grow‐out stage at stocking density 2 juvenile/m 2 ranged from 0.93 to 1.16, which is like T 2 (0.94–1.14) in this study. The range of condition factor in this study was found higher than that of some other previous studies (Karim & Uddin, 2008; Kunda et al, 2008; Lalrinsanga et al, 2012). Thus, this study suggests that zymetin and super PS probiotics enhanced the nutritional and health status of shrimp through a series of beneficial activities, including improving digestive system, protecting from pathogens, microbial balance in the gut, nutrient absorption, and supplying essential vitamins (El‐Kady et al, 2022).…”

“…On the other hand, isometric growth in C and T 2 also indicated a reasonable index of shape (Riedel et al, 2007). Positive allometric, isometric, as well as negative allometric (in females) growth pattern of prawn have been also recorded in previous studies (Azad et al, 2021; Lalrinsanga et al, 2012; Rocha et al, 2015). Similarly, higher condition factor ( K ) in T 1 throughout the entire culture cycle indicated the striking impact of probiotics to maintain their steady growth.…”

“…Variations of length-weight relationships are a good indicator in crustaceans that reflects the fluctuations of the uptake and allocation of energy, furthermore, these variations are a function of many factors such as food availability, reproductive cycle, sexes and seasons, and these were reported in both wild and cultured populations of the prawn (Lalrinsanga et al, 2012).…”

The reproductive cycle of the Macrobrachium nipponense (De Haan, 1849) was studied in Al-Hammar Marsh, Southern Iraq during Dec. 2015 to Nov. 2016.The averages of total length, carapace length and weight for males were 65.7 mm, 28.8 mm and 2.9 g respectively, and for ovigerous females were 60.1 mm, 26.0 mm and 3.3 g respectively. Length-weight relationship of M. nipponense was W= 0.407 L e 0.031 (r = 0.67) for the females and W= 0.177 L e 0.043 (r = 0.90) for the males. The highest percentage of ovigerous females was 98.88 % attained in August. The maximum gonado somatic index was recorded in March (10.66) and the minimum was 5.72 recorded in July 2016. The condition factor for the males was ranging from 1.30 to 2.90 in November and August, respectively, while for the females it was between 1.11 and 2.10 at the same periods. Total number of eggs per female was from 799 to 2047 egg/ind. Minimum sex ratio (males: females) was 1:0.17 recorded in February, and the maximum 1:9.00 was recorded in June.

“…The treatment-wise condition factor (K) was determined in the current investigation, indicating that all treatments had K values that were closer to 1. Despite variations in the stage of development, sex and culture phases, Lalrinsanga et al (2012) found that all prawns had a better condition factor (K > 1). Several authors have described a comparable variance of Kin M. rosenbergii from 0.98 to 1.08 (Abohweyere, 2009;Azad et al, 2021;Enin, 1994;Kunda et al, 2008).…”

The aim of the present study was to evaluate the water quality, growth performance, body composition, length–weight relationship, condition factors and benefit–cost analysis of giant freshwater prawn (Macrobrachium rosenbergii) cultured with biofloc system in pond conditions. The experiment was conducted in twelve (12) experimental ponds, each measuring 240 m2. The control group was cultured without any biofloc (T1), and biofloc‐based three treatments were biofloc with 100% feed (T2), biofloc with 90% feed (T3) and biofloc with 80% feed (T4). The biofloc‐based treatments showed significantly higher floc volume, total suspended solids, total heterotrophic bacteria and plankton density than the control (p < 0.05). All the growth parameters were significantly higher in biofloc‐based treatments (T2, T3 and T4) than in the control (T1). The lowest feed conversion ratio was found lowest in T4 (1.40 ± 0.02) and highest in T1 (2.13 ± 0.04), which was significantly different among the treatments (p < 0.05). The significantly highest production was obtained 939.02 ± 6.61 kg/ha in T2, and the lowest was 779.67 ± 7.50 kg/ha in T1. The length–weight relationship indicated positive allometric growth in all treatments. The condition factor ranged from 0.95 to 1.07, showing that the prawns were in good health throughout all treatments. The results of the present study indicated that M. rosenbergii can adapt to a biofloc‐based aquaculture system, and the conventional feeding rations can be reduced up to 20% without affecting the growth and production.
