Abstract
In inland saline water in an arid/semi-arid region of Haryana, India, a 60-day experiment was carried out to evaluate the growth and survival response of Amur carp, Cyprinus carpio haematopterus (Linnaeus, 1758). Following acclimatization, 300 fingerlings with an average weight of 8.38 0.04 g were evenly distributed into 5 treatment groups (salinities: control C 0 ppt; T1 3 ppt; T2 6 ppt; T3 9 ppt and T5 12 ppt) with 3 replicates in 500 L FRP tanks. Throughout the investigation, 9 ppt and 12 ppt were found to have changed behaviors such as swimming activity and appetite. While physio-chemical characteristics of the water, such as pH, temperature, and dissolved oxygen (DO), did not differ significantly over the course of the experiment, others, such as ammonia, nitrite, total dissolved solids (TDS), and conductivity, did. The highest survival rate was obtained in T1, whereas T2, T3, and T4 all showed a declining tendency as salinity increased. Fish growth (ADG, SGR, and TWG) considerably decreases (P0.05) from control to T4, although FCR significantly increases with salinity. According to the findings, Amur carp (Cyprinus carpio haematopterus) may be cultivated at a density of 6 ppt, and most likely as low as 5 ppt.
