It has been used to prepare berseem leaf meal (BLM) and leaf protein concentrate (BLPC). Proximate analysis revealed that the crude protein level in BLM and BLPC were 23.98% and 41.67% respectively. Level of anti-nutritional factor especially saponin content in BLM and BLPC were found to be 0.91% and 0.71% respectively. The alkaloids were higher in BLPC (5.55%) and BLM (3.46%). It has been recorded that saponin content reduced to 0.40% in BLM on 24 hours of water soaking. Evidence from the present study suggests that BLM and BLPC can be used as a good protein source in aquafeed.

Four iso-nitrogenous (336 g kg −1) and iso-energetic (20 MJ kg −1) diets containing 0, 100, 200, and 300 g kg −1 FJKM in replacement of 0, 33.3, 66.7, and 100% soybean meal protein, respectively, were prepared and designated as control, T1, T2, and T3, respectively. A total of 180 acclimatized fish (average weight 6.05 ± 0.04 g) were equally distributed into four experimental groups in triplicates, and were fed their respective diets to satiation twice daily at 10:00 h and 18:00 h. Higher percent weight gain (%WG); specific growth rate (SGR); protein efficiency ratio (PER); protease, aspartate amino transferase (AST), and alanine amino transferase (ALT) activities; and lower feed conversion ratio (FCR) were recorded in T2 and T3 groups compared to other groups. Whereas hepatosomatic index (HSI), intestinal somatic index (ISI), and amylase, lactate dehydrogenase (LDH), malate dehydrogenase (MDH), superoxide dismutase (SOD), and catalase activities among the various dietary groups did not vary significantly (P > 0.05). Whole body composition of fish analyzed at the end of the feeding trial exhibited significantly (P < 0.05) higher ether extract and lower crude protein in the control group compared to the FJKM-fed groups. These results indicated that rohu fingerlings can efficiently utilize FJKM without any detrimental effect on growth performance, nutrient utilization, and metabolic response.

One hundred and eighty acclimatized fingerlings of mrigal with initial body weight ranging from 2.87 ± 0.01 g to 3.26 ± 0.05 g were randomly distributed in three replicates of each of four experimental groups including control (without probiotic and prebiotic), T 1 (high probiotic + low prebiotic), T 2 (low probiotic + high prebiotic) and T 3 (high probiotic + high prebiotic), using completely randomized design (CRD). Results showed that growth performance parameters, such as specific growth rate (SGR), per cent weight gain, feed conversion ratio (FCR) and protein efficiency ratio (PER), were reported to be higher in the T 2 group followed by the T 3 group. Maximum gut microbiota activity was found in the T 3 group which was significantly different from other treatment groups. Similarly, body composition and digestive enzyme activity varied significantly (p < .05) among the treatment groups. The study showed the possibility of improved nutrient utilization in terms of growth performance and digestive enzyme activity in the group following dietary synbiotic supplementation.

Different iso-caloric and iso-nitrogenous experimental diets were formulated with supplementing five levels (0, 2, 4, 6 and 8%) of marigold flower meal. The experimental fish (n=225) were divided into five equal groups having three replicates under each group and fed respective experimental diets for a period of 60 days. The biochemical composition of fish muscle was similar in all the groups. Total carotenoids concentration (μg/g) in the skin of sword tail at the beginning and end of feeding was similar in control diet (2.94 vs 3.17). The supplementation of marigold petal meal in the diet significantly increased (P<0.05) the total carotenoid concentration in the muscle and skin of sword tail from 2.87 to 6.17 μg/g. Growth performance and nutrient utilization in fish were similar in all the experiment groups. The study revealed that marigold petal meal at the 4% level can be supplemented in the diet of swordtail for improvement of skin coloration through increase in the carotenoids concentration in skin without any adverse effect on body composition, growth and feed conversion efficiency.

Fluridone, a new systemic herbicide, worked well in controlling rooted submerged aquatic weeds. Experiment was conducted under indoor condition for 90 days and tested at different doses from 0 to 90 µgL-1 on three rooted submerged weeds i.e. Vallisneria, Najas, Hydrilla and one non-rooted weed i.e. Ceratophyllum. Fingerlings of rohu were released at higher doses of fluridone (30 to 90 µgL-1). Herbicidal symptoms of fluridone appeared within seven days and slowly killed the rooted submerged weeds over 45 to 90 days. Because of this, it didn't pollute the environment and fish didn't suffer from oxygen deficiency. Efficacy of fluridone in controlling four tested submerged weeds was of this order: Najas > Hydrilla = Vallisneria > Ceratophyllum. Analysis of blood biochemical parameters of fish revealed that fluridone had no toxic effect on fish at the doses in which it killed the weeds. Presently management of aquatic ecosystem is the only option to control submerged weeds as herbicides available in India are not effective on submerged aquatic weeds. Fluridone has the potentiality to be an ideal herbicide to solve the problem of submerged aquatic weeds in India.

It was observed that 2,4-D and glyphosate (Roundup ®) which are used for controlling floating aquatic weeds could not produce any significant effect on any of the test weeds e.g. Hydrilla, Najas, Vallisneria and Ceratophyllum even at higher than the recommended dosages @ 10-20 g/ha . Fluridone is a new systemic herbicide. It worked well for controlling four submerged weeds. Experiment was conducted in 160 litre capacity fibre tanks for 90 days under indoor condition in two phases and tested at different dosages from 0-90 ppb on three rooted submerged weeds i.e. Vallisneria, Najas, Hydrilla and one non-rooted submerged weeds i.e. Ceratophyllum with rohu fingerlings (initial length: 9.1-10.4 cm and weight: 17-37g). Fluridone has no effect on floating weeds pistia and water hyacinth in these dosages. Herbicidal symptoms of fluridone on submerged weeds appeared within seven to ten days and ...

Control group {TcPR) was fed with feed having 30% crude protein@ 3% of body weight for 90 days trial period. Other experimental groups T 1 PR was alternatively 3 days fed with feed having 20% CP and 30% CP@ 3% of body weight, T 2 PR was alternatively 7 days fed with feed having 20% CP and 30% CP@ 3% of body weight, T 3 PR was alternatively 15 days fed with feed having 20% CP and 30% CP@ 3% of body weight and T 4 PR was alternatively 25 days fed with feed having 20% CP and 30% CP@ 3% of body weight during 90 days trial period with daily ration in two equal halves at morning and afternoon. It was noticed that retention of different nutrients was almost similar among all treatment groups indicated improvement of digestibility of nutrients might not be the mechanisms for recovery growth in carps. Increased percent feed intake of body weight (hyperphagia) (4.14 ± 0.30 or 4.94 ± 0.46 and 3.33 ± 0.29), improved specific growth rate (1.86 ± 0.09 or 2.26 ± 0.05 and 1.43 ± 0.01), absolute growth rate (1.57 ± 0.08 or 1.84 ± 0.18 and 1.36 ± 0.12), protein efficiency ratio (1.19 ± 0.11 or1.16 ± 0.12 and 1.05 ± 0.09) were the important mechanism showing better performance index {21.60 ± 1.09 or 23.80 ± 0.21 and 19.45 ± 0.37) through which the experimental groups which were protein restricted and re-alimented at 3 or 7 days alternatively during 90 days trial period could able to compensate the growth retardation and to catch up the final body weight of control (128.68 ± 11.53 g/f) but other experimental groups failed to compensate during 90 days trial period. Result of the present study indicated that deprived fish i.e., fish received alternate 3 or 7 days protein restriction andre-alimentation showed recovery growth had still lower values of Hb {10.21 ± 0.02, and 9.88 ± 0.04 g/dl), haematocrit value (30.62 ± 0.05 and 26.64 ± 0.11%), total erythrocytic count (3.40 ± 0.01 and 3.29 ± 0.01 X10 6 mm 142 Parimal Sardar*, S. K. Prabhakar, S.C. Dutta and H. S. Minhas haematological and biochemical parameters studied were proportionately lowered in the experimental group got higher degree of deprivation. These findings suggested that with the increase of trial length complete compensation of haematological and biochemical profiles of rohu might be achieved. The results indicated that the implementation of alternative 1 days low and high protein diet feeding during aquaculture of carps could make economize the operation through minimizing the feed input cost.

Four experimental soy protein-based diets D0 (without lysine or methionine supplementation), D1 (lysine supplementation alone), D2 (methionine supplementation alone) and D3 (both lysine and methionine supplementation) were fed to triplicate groups. l-Lysine and dl-methionine were added to the diets containing 550 g kg−1 soybean meals at 4 and 7 g kg−1 of dry diet respectively. Significant higher weight gain, specific growth rate (SGR), protein efficiency ratio (PER), dry matter retention, nitrogen retention, total ash retention, whole carcass protein, haemoglobin concentration, haematocrit value, total erythrocytic count, total leucocytic count, plasma glucose and plasma total protein and lower FCR, per cent lipid retention and whole body moisture content were observed in fish fed soya protein-based diet supplemented with both lysine and methionine than that of fish of other dietary groups at the end of 8 weeks feeding trial. Although fish fed diet supplemented with either methionine or lysine did not show any significant differences of growth performances, feed utilization, carcass composition and haemato-biochemical status, fish of both of these dietary groups showed significantly better growth performances, feed utilization, carcass composition and haemato-biochemical status than that of fish fed diet without lysine and methionine supplementation.
