Davis 1998 <p>The Nepalese government and some 225 families in the private sector are engaged in an expanding aquaculture program in lakes Phewa, Begnas and Rupa in the Pokhara Valley, Nepal (Swar &amp; Pradhan 1992). Bighead carp (<i>Aristichthys nobilis</i>) and silver carp (<i>Hypopthalmichthys molitrix</i>) are propagated in hatchery ponds and are raised to market size in mesh enclosures (having sides, tops and bottoms) suspended to a depth of 2 m. Some 300 cages are presently in use, with annual production varying from 3.4 kg/m³ Lake Phewa to about 5 kg/m³ in lakes Begnas and Rupa (Swar &amp; Pradhan 1992). These cage-reared fish are an important source of animal protein and revenue (Swar 1981). Tourism in the region provides growers a continuous market for their fish.</p> application/pdf 10.1080/03680770.1995.11901140 en Taylor & Francis Use of a subsurface plankton layer to benefit a cage-culture fishery in Lake Phewa, Nepal article
