Effect of some immunostimulants as feed additives on the survival and growth performance of Nile tilapia, Oreochromis niloticus and their response to artificial infection
Type: Journal Article
Four plant based immunostimulants (Echinacea purpurea 0.25 and 1.0 ppt, Allium sativum 3 %, Nigella sativa 3% and Origanum marjorana 2 and 3% and mixture of Allium sativum , Nigella sativa 3:1, 1:3 and 3:3%, respectively ...
Mass spawning of Oreochromis niloticus for fry production: threats and opportunities for small-scale aquaculture and selective breeding
Type: Book Chapter
Mass selection based on mass spawning can present a feasible and low-cost selective breeding scheme. In mass spawning, however, mating is not controlled and a small number of breeding individuals may account for a ...
Phenotypic and genetic parameters for body measurements, reproductive traits and gut length of Nile tilapia (Oreochromis niloticus) selected for growth in low-input earthen ponds
Type: Journal Article
In this study we present estimates of phenotypic and genetic parameters for body size measurements, reproductive traits, and gut length for Nile tilapia (Oreochromis niloticus) selected for growth in fertilized earthen ...
Selecting Nile tilapia (Oreochromis niloticus) for growth in low-input environments
Type: Book Chapter
This chapter presents the results from a selective breeding experiment with Nile tilapia in a low input pond environment. The environment was defined as low input as the pond only received chicken manure for fertilisation. ...
