Comparative Study on Growth Performance and Proximate Composition of Meat and Internal Organs of Farmed and Wild Cirrhinus mrigala

Fish play an enormous role in the diet of humans and are a great source of essential nutrients. Simple techniques determined growth performance. The tape foot was used to determine the length, and the weighing balance was used to calculate the weight. Proximate composition is the measurement of the percentage of proteins, fats, carbohydrates, ash percentage and moisture content. The present-day study was helpful in analyzing the accurate difference in body composition as well as the difference in growth rate of wild and farmed Cirrhinus mrigala. Twenty-one farmed and wild Cirrhinus mrigala in three (3) weight groups, such as W1 (250-500g), W2 (501-1000g) and W3 (1001-1500g) were taken from Satyana Road Fish Farm, Faisalabad and Trimu headworks Jhang Sadar, respectively. Each of the fish was fed on three types of treatments T1 (25% CP or 250g protein in 1kg) T2 (30% CP 300g in 1kg) and T3(35% CP 350g in 1kg) according to weight categories. At the end of the experimental trial, each fish was weighed individually (W1) and weighed after dressing loss (W2). Micro Kjeldahl method was used to determine the protein percentage and Crude fat was determined by using ether extract extraction method in the Soxhlet system. Total ash percentage was calculated by burning the sample in the muffle furnace. To determine the moisture contents, one gram of the samples of fish organs was placed in weighed Petri dishes and was dried in the oven at 105Celsius for twelve hours. The samples were taken to vacuum desiccators for five minutes and weight was recorded continuing this drying practice.  For one to two hours the samples were again kept in oven until they achieve their invariable weight. Data was subjected to statistical analysis. Analysis of variance was performed to compare means.
