Short communication: The effect of feed ingredients on the settling velocity of feces in tilapia (Oreochromis niloticus L.)
Knowledge on the solid waste characteristics is valuable to set up a proper facility in order to increase the removal efficiency and also to understand the factors influencing waste quality. There are two main methods to evaluate removal efficiency of solids generated from a fish farm: feces recovery percentage and settling velocity of feces. Both the recovery efficiency and settling velocity of particles generally have a direct relationship to the weight and size of particles (the heavier the particle, the faster the deposit). Manipulation of diet composition alters fecal physical properties improving feces consistency and leading to a higher recovery and a larger particle size.
