| Abstract | Effects of zooplankton refuge on the growth of tilapia (Oreochromis niloticus) and plankton dynamics in pond were assessed by using 12 land-based experimental enclosures (7 m× 4 m) in a saline–alkaline pond. There were 4 treatments resulting from a combination of 2 stocking densities of tilapia (5 and 10 kg per enclosure) and 2 enclosure types (refuge and nonrefuge). Each treatment had three replicates. In the enclosures with refuge, all fish were excluded from a water column ¼ of the enclosure’s size with a polyethylene net (1.5 cm mesh size). Our field experiment showed that the individual gain in weight of tilapia increased 6.4 times with refuge treatment at the stocking density of 5 kg per enclosure than that in nonrefuge treatment. But at the stocking density of 10 kg per enclosure, the individual fish weight in all enclosures decreased due to the excessive density of fish stocking. Our results also showed that the refuge significantly increased the rotifer biomass and phytoplankton diversity and decreased the phytoplankton biomass (P < 0.05), but the copepod biomass was not affected by the refuge. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
