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 ...
Mating systems and male reproductive success in Nile tilapia (Oreochromis niloticus): a microsatelite analysis
Type: Journal Article
Fry production in Nile tilapia, Oreochromis niloticus is typically achieved by mass spawning of males and females stocked in large hapas suspended in ponds. In such spawning aggregations, territorial behavior and reproductive ...
Heritability estimates and response to selection for growth of Nile tilapia (Oreochromis niloticus) in low-input earthen ponds
Type: Journal Article
This study presents results of two generations of selection (G1 and G2) for growth of Nile tilapia. The selection environment consisted of earthen ponds which were fertilized daily with 50 kg dry matter (dm)/ha chicken ...
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. ...
