JAIME-CEBALLOS, Barbarito et al. Use of Spirulina platensis meal as feed attractant in diets for shrimp Litopenaeus schmitti. Hidrobiológica [online]. 2007, vol.17, n.2, pp.113-117. ISSN 0188-8897.

An experiment was conducted at the wet laboratory of the Fisheries Research Centre, Havana, Cuba, to evaluate the attractability of a pelleted diet containing Spirulina platensis meal for Litopenaeus schmitii juvenile. The design was completely randomized with 4 treatments and 6 repetitions. Two diets: a diet containing 5% of Spirulina platensis meal and a control diet without it, and two positions of the feed were assayed inside an experimental device consisting in a rectangular glass aquarium in which two internal glass walls were placed in order to have three equal sections. Ten shrimps with mean weight of 0.503 ± 0.018 g were placed in the central section of the aquarium, with access to the other two sections, where the experimental diets were placed. A bifactorial analysis showed that the attraction was significatly affected by type of feed, although the position did not have any significant effect. A greater percentage of shrimp (68%) moved toward the position where the diet containing Spirulina platensis meal was placed, and ingested the diet. It is concluded that the inclusion of 5% of Spirulina platensis meal improved the attractability of the feed for Litopenaeus schmitti.
