The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Behavioural Analysis of Zebrafish: Shoaling and Fear ResponsesLuca, Ruxandra Monica 15 February 2010 (has links)
Zebrafish, a novel vertebrate model organism, has a high nucleotide sequence homology with human genes. Its transparent and fast developing embryo allows the analysis of physiological and anatomical characteristics, many of which are similar to those of mammals. Although the prolific nature of zebrafish can facilitate genetic studies, linking genes and behaviour is difficult because behaviour is not well investigated in zebrafish. The aim of this project is to develop robust behavioural tests that can quantify shoaling with conspecifics and fear responses to natural predators. Eight conditions using different computer-animated stimuli were used to induce behavioural responses. The results demonstrate that shoaling behaviours and fear responses can be successfully induced. More importantly, the behaviours caused by the computer-animated images confirm previous research findings using natural conspecifics and predators. Thus, computer-animated images will help standardize behavioural tests in zebrafish and will lead the way to more sophisticated and better controlled experiments.
