Why should you feed your tilapia larvae with high quality micro-extruded feed ? By By Delphine Weissman, R&D Aquaculture manager – DRDI, Neovia Group.

Intensification of aquaculture and the increasing need in fish coming from aquaculture require high quality fish larvae for an efficient production. A good feeding in early phases will ensure a good production in terms of survival, deformities and growth in the future carrier of the fish. Tilapia as one of the most farmed species over the world is often fed with crumbled feed during the first feeding days after yolk sac absorption.

pellets. The feed nutritional balance is guaranteed by the high nutrients levels and the noble raw materials used in the formula. All these features lead to good survival rate, twice faster growth and optimal FCR.

The study presented here shows the great technical interest of using high quality micro-extruded feed to feed tilapia fingerlings during the first 28 days after yolk sac absorption. MEM® from BernAqua is a micro-extruded feed that ensures the right size of pellets for the fish. It avoids water pollution due to its good stability in water (see Figure 1) allowed by its unique technology: cold micro-extrusion and marumerization. It permits a good catch-up by the fish thanks to its good dispersion in water and the slow sinking behavior of the
