Abstract
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.
Highlights
Ground and surface water are the two major water sources used in fish farming
After the experiment of six weeks, results revealed that that fish gain more body length and weight in groundwater as compared to the surface water this might be due to the fact that ground water has all the favorable qualities (Table 2) that can promote fish growth
As the water is important parameter in fresh growth the water source is considered in the experiment
Summary
Ground and surface water are the two major water sources used in fish farming. In several ways groundwater ( termed as well-water or spring water) frequently varies in quality parameters from surface water. Groundwater is generally regarded as one of the most valuable water source for fish farming because it generally consistent in quantity and quality at some particular site. Supplementary nourishing is thought to extend the carrying capacity of ways of life frameworks and can enhance the fish growth by the utilization of numerous folds (Davendra et al, 2002). It too gives the primary rate strategy of nutrients need inside the most limited conceivable time inside the lakes. Attempts have already been taken to secure the net level of
