Marine Algae Based-Meal as Substitute Ingredient Feeds for the Fighting Conch Strombus tricornis L. (Mollusca, Gastropoda): Body Weights and Histomorphological Studies
Strombus tricornis is a true conch among Strombidae species predominately exploited for feeding and jewelry production. Intensive conch culture targets higher growth rates using convenient formulated feed under suitable conditions. Moreover, the efficacy of the digestive system mainly depends on the nutritive value of aqua feed. Currently, nutriment scientists attempt to use marine algae as an alternative protein for aquatic feed. Hence, an assessment was made to compare the inclusion of seaweed and protein sources in Strombus tricornis diet using five experimental diets (D). D1, D2 and D3 integrated with racemosa, J. rubens,and D. ciliolate, respectively, while D4 and D5 incorporated with animal and plant protein, respectively. Each diet was run into three replicates of conchs in 60 liters of aquaria at 30- 32°C for three months. The final body weight of Strombus conchs simultaneous with histomorphology characteristics of the digestive system and muscles were evaluated for five treatments. Results ensured that seaweed enhanced growth for further increased final body weight. Histomorphological results exhibited normal intestinal epithelium of columnar cells and well-studiated muscle fibers when compared with those of control and commercial diets. In conclusion, algae act as a proper alternative feed for protein sources of Strombus.
