ABSTRACT
The present study was carried out to record growth respose of Labeo rohita fingerlings fed with Lactobacillus rhamnosus supplemented feed. In a completely randomized design fishes were divided into two different treatments based on feeding with and without probiotics in canola meal and corn gluten meal. The control group was fed with commercial feed. Before stocking, all the aquaria were dried for 3 days. One eighty hundred and eighty fish (Labeo rohita) were stocked in 9 aquaria. Twenty fishes were kept in each group. Before stocking, the fish was treated with KMnO4. In treatment 1 (T1) fish were fed with canola meal along with Lactobacillus rhamnosus (NR-113332.1). In treatment 2 (T2) fish were fed with corn gluten meal along with Lactobacillus rhamnosus. The fish were fed at the rate of 3% body weight. All the fish were carefully weighed during the trial to verify the result of feed on growth. Feed was readjusted after every fortnight’s sampling. The initial mean weight of the experimental fish (Labeo rohita) was recorded as 40.01±1.00g, 39.67±0.76 g, and 40.01±1.00 g for T1, T2, and control group respectively. After 90 days the highest weight gain was found in case of T1, (683.64c ±1.93) and the lowest one (479.35 ±1.8g) was recorded in the control group. Significant differences were found in the feed conversion ratio between the control group (2.02±0.07), T1 (1.65±0.01) and T2 (1.74±0.01). Survival remained 100% in all the treatments. Water quality parameters remained in a favorable range throughout the study period, and non-significant differences were recorded for the different treatment groups. All the treatments showed low fat contents and good crude protein values of the fish meat. It is concluded that fish production can be enhanced with the addition of the probiotic in the feed derived from plant origin ingredients. This practice will economize, promote growth and prevent feed associated stress in the aquaculture industry in this country in an environmentally sustainable way.
