<b>Reproduction performance of female Nile tilapia under different environments and age classes

Abstract: ). The females were divided into three age classes, corresponding to animals under one year (age 1); between one to two years (age 2); and over three years old (age 3). Spawning was verified once a week, from October 2012 to March 2013, corresponding to a 23-week assessment. The statistical analyses were performed with Proc Genmod from the statistical program SAS. Site 2 had the lowest results when compared to the other sites for multiple spawning, spawning frequency and volume of eggs/female for animals of ag… Show more

“…The major problems for seed production of Nile tilapias Oreochromis niloticus (Linnaeus, 1758) are the low egg production during spawning and a lack of spawning synchrony (Bhujel, ). To overcome these issues, a variety of management strategies have been tested and recommended (Campos‐Mendoza, McAndrew, Coward & Bromage, ; El‐Sayed & Kawanna, ; Little, Coward, Bhujel, Pham & Bromage, ; Ridha & Cruz, ; Tsadik & Bart, ; Yoshida, Oliveira, Kunita, Rizzato & Ribeiro, ). Beyond management strategies, the choice of production system may contribute to improving the reproductive performance of this species (Ekasari et al., ).…”
