Abstract:

Balanced feed represents approximately 60 % of production costs in fish culture and ration size has significant effects on this parameter. Ration size varies according to culture strategies and producer knowledge. It can also have environmental implications since feed can be a pollutant. A bioeconomic model was developed for an...

Partial substitution of balanced feed by Chaya leaves in Nile tilapia production: a bioeconomic analysis

Tilapia culture in Yucatan State, Mexico, is largely semi-intensive. The producers are mostly poor farmers who receive government subsidies for purchase of fingerlings and balanced feed.
