| Abstract | Zebrafish (Danio rerio) have an innate tendency to join shoals. Based on this, we refined visual choice tests to focus on social interaction and novelty preference. Our design follows mouse three-chamber sociability protocols, except testing is conducted under 940 Lux fluorescent lighting. Initially, we compared performance among zebrafish strains: inbred (AB) or wild-crossbred (WIK) from Zebrafish International Resource Center, to golden and short-fin from Petco stores. AB fish exhibited a preference for shoaling; they dwelled longest near transparent boxes containing zebrafish, while short fin favored blue boxes without fish. AB and golden exhibited a strong preference for social novelty, not evident in short-fin or WIK fish. Serotonin and cannabinoids shape mammalian social behavior, and equivalents of both receptor types are expressed in the zebrafish brain. We examined the effects of the cannabinoid receptor agonist WIN 55,212-2 (1 mg/l), or serotonin 5-HT(1A) receptor agonist buspirone (10 mg/l) on Petco short-fin social choice. Fish were bath exposed to test compounds for 10 min, under these conditions [(3) H]CP55,940 (4 nm) bound to brain with a concentration of 1.9-6.4 fmol/mg 5-30 min afterward. Social approach was measured 20 min after acclimation to the test arena. WIN 55,212-2 and buspirone increased dwelling near boxed zebrafish. In zebrafish whole-brain homogenates, buspirone displaced [(3) H] 8-hydroxy-N,N-dipropylaminotetralin (dissociation constant, K(D) = 16 ± 1.2 nm) with an inhibition constant (K(i) ) of 1.8 ± 1.0 nm lower than that of WAY 100,635 (K(i) â¼1000 nm). These fish social choice tests may enhance social behavior research, and are useful for studying the effects of genetic manipulations, pharmaceuticals or environmental toxins. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
