“…In the present study, the growth rate was lower and FCR was comparatively poor which is due to severe winter season during the period of experiment (November–January). This is in agreement with Hossain, Khatun, Kamal, Habib, Tumpa, Subba and Hossain () who reported that growth rate and total production of mirror carp, Cyprinus carpio Ver. Specularis was very poor in winter season.…”

A feeding trial was conducted for 90 days to assess the metabolic and digestive enzyme activity in response to alternate or mixed feeding of different protein levels in the diet of Pangasianodon hypophthalmus fingerlings. One hundred and forty four fingerlings with an average weight of 5.0-5.5 g were distributed into four experimental groups each with triplicate. Four iso-caloric diets with varying level of crude protein viz., 35%, 30%, 25% and 20% were made and designated as diet 35P, 30P, 25P and 20P respectively. Four treatments were maintained based on four different feeding schedules such as continuous feeding of diet 35P (35P/35P), alternate feeding of 1 day diet 35P next day diet 30P (35P/30P), alternate feeding of 1 day diet 35P next day diet 25P (35P/ 25P) and alternate feeding of 1 day diet 35P next day diet 20P (35P/20P). As a result, specific growth rate (SGR) and weight gain percentage were relatively higher in treatment (35P/25P) followed by (35P/35P) and (35P/30P). The metabolic enzymes such as lactate dehydrogenase (LDH), malate dehydrogenase (MDH), glucose-6-phosphate dehydrogenase (G6PDH), Glucose-6-phosphatase (G6Pase), alkaline phosphatase (ALP), acid phosphatase (ACP), alanine aminotransferase (ALT), aspartate aminotransferase (AST) were expressed better in (35P/35P) group followed by (35P/25P) and (35P/30P) groups. The digestive enzymes, protease and lipase activities were higher in (35P/35P) and (35P/ 25P) groups. The present study revealed that the better nutrient utilization and growth of 35P/25P group is because of their balanced digestive and metabolic enzyme activities through alternate level of higher and lower protein diet.

“…Taher et al (2014) recorded DGR of 3.16, SGR of 1.85 % day −1 and FCR of 2.63 for common carp fed 5 % feeding level in floating cages. 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) pointed out that SGR of 2.44 % day −1 and FCR of 2.12 for common carp reared in semi-closed system for 52 days.…”

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.
