Science , NAU • Year:- 2018 TUNGABHADRsetelite DAM view Nandanavana Garden TBD Tungabhadra River & Dam River Tungabhadra River TUNGABHADRA and BHIMA are main tributaries of river KRISHNA. STATES:- Karnataka ,Telangana , Andhra Pradesh TRIBUTARIES:- LEFT:- Tunga , Kumudvati & Varada River RIGHT:- Bhadra , vedavathi & Handri River SOURCE:-koodi (Place wehere the Thunga & Bhadra rivers meet) LENGTH:- 531km BASIN:- 71,417 km.2 Tungabhadra Reservoir This reservoir is the only place in india where reservoir – based pen culture is being carried out from year 1982 onwards for the rearing of carp seed. The reservoir has a water spread area of 37,814 ha. Growth and survival of rohu spawn in pens with varying stocking desities commissioned in the perhiphery of Tungabhadra reservoir was studied by Gireesha et al (2003). Soil charecteristics recorded at the beginning of the study (Gireesha et al , 2003) Sir No. Charecteristics Range 1. NO3-N(ppm) 0.132-0.382 2. P2O5(ppm) 1.08-2.05 3. Organic matter(%) pH 0.23-(-0.46) 4. 7.1-9.9 Zooplankton in the Pens The zooplankton in the pens mostly consisted of rotifers (branchionus , Filinia , Conochilus ,Asplanchna) , copepods (Diaptomus and Cyclops and their larval stages) , cladocerans (Daphnia , Moina) and ostracods (Cypris). The volume of zooplankton ranged between 1.5 and 3.5 ml/50 liter water during the period of investigetion.

CRAFT AND GEAR Coracle , the saucer-shaped country craft , made of split bamboo and covered with hide , is the most commonly used fishing craft.
