Large scale hatchery production of Penaeus monodon using natural food and artificial diets

Natural food in combination with either SEAFDEC formulated or other commercial larvae diets was tested for large scale production of Penaeus monodon postlarvae. Two trials of 3 treatments each, 2 replications of each treatment, were conducted in 10 m3 circular concrete tanks. Shrimps were reared from nauplii to postlarvae. Dietary treatments for trial I included:(a) natural food (NF) alone, (b) NF+ commercial plankton substitute (PS) and (c) NF+ SEAFDEC diet (SD).For trial II, commercial powder diets SP or SMP were added:(a) NF + SP, (b) NF + PS + SP + SMP and (c) NF + SD + SP + SMP. Larvae survival was significantly higher in treatments containing the SEAFDEC diets than in the treatments receiving natural food alone (trial I) or natural food in combination with SP (trial II). Larval development was faster in the group fed the SEAFDEC diet; larvae in these groups metamorphosed into postlarvae an average of 1-2 days earlier than groups fed other diets. The presence of either SP or SMP did not improve the efficiency of the feeds. Results showed that larvae performance was affected by the nutrient composition of the diets and that by using proper feeding techniques and management of water quality, large scale hatchery production of P. monodon using natural food in combination with the SEAFDEC diet or plankton substitute is possible.

Primavera, J. H. (Elsevier, 1998)A total of 4845 penaeids belonging to nine species—Metapenaeus anchistus, M. ensis, M. moyebi, M. philippinensis, Penaeus merguiensis, P. monodon, P. semisulcatus, P. latisulcatus and Metapenaeopsis palmensis—were collected ...
Piedad-Pascual, F. (Institut Francais de Recherche pour l'Exploitation de la Mer, 1990)Marine shrimps absorb minerals from their aquatic environment aside from the minerals that come from the food they eat. Thus, the dietary requirement of shrimps for certain minerals will depend on the amounts and availability ...
