Narasimha Ramulu.K | Benarjee.G

Abstract: In the present study an attempt has been made to study the Ichthyo fauna diversity and fish production in some reservoirs in Northern Telangana districts during the year 2012 to 2014. North Telangana Zone includes the five districts i. e Adilabad, Karimnagar, Nizamabad, Medak (except southern borders) and Warangal (except western portion and N. W. Part), North-eastern tips of Nalgonda and Khammam (most parts of Khammam). In North Telangana Zone Karimnagar district has the maximum number of reservoirs (10) followed by Nalgonda (9), Nizamabad (6), Warangal (5) districts. Nalgonda, Karimnagar have large concentration of small reservoirs. Medium reservoirs are well dispersed among the districts and 4 large reservoirs are distributed among Karimnagar and Nizamabad district. Majority of the reservoirs in the North Telangana Zone are small (24), followed by those in the medium (12) and large (04) as suggested by Srivastava et al. , [3] and Anon, [14]. In the present study the fish yield has been estimated for the consecutive years (for a period of two years from 2012-2014). It is observed that the fish production has increased from 1, 48, 799tonnes to 1, 86, 960 tonnes where as the fresh water prawn production was decreased from 3, 229 tonnes to 1, 881 tonnes. However in order to increase fish production there has been an increase of pressure on these water bodies that leads to ecological imbalance, it is observed.
