Abstract

In the world, the great amount of aquaculture products comes from small and medium farms and in Brazil the family aquaculture also contributes to the production of fish. In the west of São Paulo State, producers of tilapia in cages show the high price of feed and the poor quality and lower amount of tilapia juveniles as the main problems of the sector. In this sense, the production of Nile tilapia juveniles to supply the cage farms is an interesting option for family farmers obtain income and diversify their production. One way to improve the efficiency of this system is reducing the feeding cost. In a recent study carried out by our research group (Process FAPESP 2013/18721-6), we tested the inclusion of bamboo substrates for the production of periphyton in cages and we found that, depending on the biomass of stocked fish and the feed management (with or without feed restriction), the inclusion of the substrate can reduce 40% of the feed intake, also reducing 55 days of the productive. Thus, we defend the need to assess the inclusion of substrates in juvenile of Nile tilapia production (average weight 2-40 g), in order to propose a production model more efficient and profitable so that in small productive modules, small producers could obtain income and sustain long-term its activity. An experiment in split plot with two main factors (with substrate and without substrate) and two secondary factors (100% and 50% of the recommended daily amount of diet), with 3 repetitions, will be installed in six ponds with two hapas inside each one. The experimental unit will be represented by one hapa. We will assess: growth performance, cumulative mortality, health, stomach contents, technical and economic viability and the ecosystem services provided by this system. (AU)
