The human body cannot make significant required quantities of vital nutrients but fish is minimum-fat, big-protein nutrition that delivers a variety of health advantages. Several external factors including temperature, oxygen level, alkalinity and photoperiod have impact on growth rate while water is also an important parameter in fish rising. Therefore, there is need to work and evaluate impact of fish food and water quality to improve the fish growth. For this purpose, twelve glass aquaria (six with ground water and six with surface water) were considered to assess growth and food conversion ratio (FCR) of Catla Catla and Labeo Rohita and two feeds (i.e. sunflower and bone meal) were provided. The feed has been given twice a day and changed 4% on the rate of body weight of fingerlings in the ground water pond and surface water pond as well. The fingerlings get the most elevated body weight in ground water and on sunflower meal (1.43 ± 0.01 g) as compared to surface water and bone meal (1.39 ± 0.03 g). The general lengths obtained using the fish feed have gotten to be (5.78 ± 0.03cm) on sunflower meal and (5.47±0.03 cm) on the bone meal. The values of FCR had been lower (better) on sunflower meal (2.13±0.01) as compared to bone feast (2.32±0.03). In conclusion, it was observed from the results that fishes fed on sunflower meals had shown better growth with improved morphometric parameters and lower FCR values.

Immense amount of wastewater is used for irrigation of vegetables and crops in order to cope with water scarcity issues in Pakistan. Wastewater is highly contaminated due to the disposal of untreated industrial wastewater into the main drains. Therefore, crops and vegetables have concentrations of heavy metals and other contaminants. The study was conducted at Chokera wastewater treatment plant in district Faisalabad, where wastewater is used for irrigation of vegetables. Samples of wastewater were collected from the drain during different time interval to find out variations in wastewater characteristics. Samples of irrigation wastewater and cultivated vegetables by wastewater were collected and investigated to check the Arsenic concentrations in vegetables. Soil samples and groundwater samples from the nearby vicinity have been taken so as to investigate the impact of wastewater characteristics which is being used for irrigation purposes. Furthermore, health risk assessment due to arsenic was conducted because consumption of wastewater irrigated vegetables. Results of selected vegetables shown that the edible portions of vegetables had average concentrations of Ni, Pb, Cd and Cr as 30.14, 27.49, 27.67 and 7.56 mg kg-1, respectively. All the water samples were alkaline. The mean concentrations of Ni, Pb, Cd and Cr in leaves samples were 30.78, 15.58, 12.37 and 3.74 mg kg-1, respectively. Waste water without treatment is not fit for irrigation to the vegetables.
