One of the important economic activities in the Amazon region is aquaculture, an activity that is affected by the high cost of acquiring food for fish larvae. The activity of the benefit of cattle generates by-products such as blood the source of iron. One of the stated objectives is to take advantage of spray-dried dehydrated blood for use as a coverage of pectin microparticles by ionic gelation using low-grade pectin coated with bovine blood proteins and maiden's skin jelly in an attempt to mimic the composition centesimal found in Artemia nauplii, a live food commonly used in the intensive rearing of fish larvae. The highest amounts of protein were obtained in the combination of temperature of ~ 35°C to ~ 150°C and flow rate of 6 to 8 v/s. The microparticles produced by ionic gelation were coated with bovine blood and maiden skin jelly proteins containing a mixture of oils (sacha inchi, fish and aguaje) sacha inchi oil was used as active. The size of the microparticles without protein coating measured 185.25µm ±7.45. Microparticles coated with bovine blood decreased in size compared to the size of the gelatin-coated microparticles of maiden skin. The combination of ionic gelation and electrostatic interaction produced a diet for fish larvae of ~ 60% protein and ~ 20% lipids. The centesimal composition of the microparticles mimic to the live food of fish larvae. Scanning electron microscopy was used to evaluate the resistance of the microparticles to the drying process.
