Optimizing prepared feed ration for somatic growth and gonad production of the sea urchin Tripneustes gratilla (Linnaeus 1758)

Asia Facundo B., . Optimizing prepared feed ration for somatic growth and gonad production of the sea urchin Tripneustes gratilla (Linnaeus 1758). pp. 71-84. ISSN 0116-6514

Somatic growth and gonad production and quality of the sea urchin T. gratilla fed with prepared diets with Sargassum sp. as feed base at different feeding rations was studied in vitro using glass aquaria from April to August 2006. The trial consisted of five treatments with three equal replications arranged in Completely Randomized Design as follows: I-Fresh Sargassum sp. (control) II-Dried pellets at 2 body weight (BW) day-1 III-Dried pellets at 3 BW day- IV-Dried pellets at 4 BW day- and V-Dried pellets at 5 BW day-. Results show that Treatments I IV and V significantly (p0.05) gave better results than Treatments II and III. The highest monthly mean growth increment was observed in Treatment V which was significantly higher (p 0.05) than all the treatments except for Treatment IV. These results show that dried pellets feeding ration was optimized at 4 to 5 BW day- for somatic growth and gonad production and quality. Significantly higher gonadosomatic index (p0.05) was also observed in Treatments I IV and V than Treatments III and II respectively. Treatments II and III did not differ significantly.

Abstract

Somatic growth and gonad production and quality of the sea urchin T. gratilla fed with prepared diets with Sargassum sp. as feed base at different feeding rations was studied in vitro using glass aquaria from April to August 2006. The trial consisted of five treatments with three equal replications arranged in Completely Randomized Design as follows: I-Fresh Sargassum sp. (control) II-Dried pellets at 2 body weight (BW) day-1 III-Dried pellets at 3 BW day- IV-Dried pellets at 4 BW day- and V-Dried pellets at 5 BW day-. Results show that Treatments I IV and V significantly (p0.05) gave better results than Treatments II and III. The highest monthly mean growth increment was observed in Treatment V which was significantly higher (p 0.05) than all the treatments except for Treatment IV. These results show that dried pellets feeding ration was optimized at 4 to 5 BW day- for somatic growth and gonad production and quality. Significantly higher gonadosomatic index (p0.05) was also observed in Treatments I IV and V than Treatments III and II respectively. Treatments II and III did not differ significantly.
