The population characteristics of O. niloticus from Kelavarappalli Reservoir, a small reservoir of Tamil Nadu, were studied. The von Bertalanffy growth parameters (VBGF) were estimated using ELEFAN. The L∞values were 38.7 cm and 37.6 cm for males and females, respectively. The growth coefficient K was estimated at 0.65 (males) and 0.73 (females). The fishes showed isometric growth. The fishing mortality (F) was 2.4 yr-1, the natural mortality rate (M) was 1.2 yr-1 and the total instantaneous mortality rate (Z) was estimated at 3.6 yr-1. The probability of capture of O. niloticus was 25% at 12.2 cm, 50% at 12.7 cm and 75% at 16.9 cm size range. The relative yield-per-recruit (Y'/ R) and biomass-per-recruit (B'/ R) were derived from the growth parameters and the values were 0.33 and 1.88 respectively. The expected yield at various levels of fishing mortality shows that yield increased with increased fishing suggesting that it can be increased by enhancing the effort up to an exploitation rate (E) value of 0.56. The present exploitation rate (E= 0.67) is beyond MSY and therefore the catch is declining. To sustain the tilapia fishery at Kelavarapalli the exploitation rate should be brought down to 0.56 from the present 0.67. The biomass per recruit against exploitation ratio reveals that half the stock is reduced at an exploitation ratio of 0.31. Further expansion of fishing here will be detrimental to the stock of tilapia as it suffers from both growth overfishing and recruitment overfishing.

Among these rivers, the fish diversity of the Yamuna, the Gandak, the Kathajodi, and the Tons (Tamas) have been studied for the first time by ICAR-CIFRI. River Ganga was the most frequently studied river while the ichthyofaunal studies of the river Tapti was done in a gap of over 50 years. Similarly, the entire stretch of the river Cauvery was studied after a gap of 28 years. The study highlights the need to explore fish fauna of the whole stretches of the major rivers of India at regular intervals to build a comparable database that might be utilized by the stakeholders for research, planning and management activities.
