The study on the evaluation of a high speed tagging device for Oreochromis niloticus (Nile tilapia) stock assessment was conducted in the Vunania dam in the Kasena-Nankana District of the Upper East Region of Ghana for two months(April-May 2014). A total of 49 Nile tilapia fishes were obtained during the period of study. Out of this number 28 were males and 21 were females representing 57.1% and 42.9% respectively. In the research the females Oreochromis niloticus had a range of 11 cm to 20 cm total length with a standard deviation of 2.0998 and a weight range of 25 g to 140 g with a standard deviation of 28.7697. Males had a range of 11.30 cm to 16.8 cm with a standard deviation 1.4409 and a total weight range of 27 g to 110 g with a standard deviation of 18.4637. In totality the sampled Oreochromis niloticus had a minimum weight of 25 g and maximum of 140 g and a mean of 82.5, minimum length of 11 cm and a maximum of 20 cm and a mean of 15.5. MS222 at a dose of 0.3 g/l [23] was used for the sedation with a minimum sedation time of 12 sec and maximum time of 238 sec and a mean of 125, minimum recovery time of 27 sec and a maximum of 311 sec and a mean of 169, a minimum tagging time of 4sec and a maximum of 122 sec and mean of 63.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
