Abstract

An inexpensive, simple and effective method is described for preparing water-stable diets suitable for aquatic crustacean feeding experiments. Seven representative diets ranging from 25 to 40% total protein were prepared and tested for their dry weight loss in water for 1-, 3- and 5-hour periods. Dissolution was influenced by diet composition, and loss was greater in fresh water than in sea water. Diets were subsequently fed to both marine shrimp (Penaeus sp.) and fresh water Malaysian prawns (Macrobrachium rosenbergii) held under experimental conditions. Results of these trials showed that diets were capable of producing a 106–329% increase in weight in juvenile Penaeid shrimp over a 25-day period. Growth appeared to increase with amount of protein in the diet. Juvenile Malaysian prawns held under mass culture conditions for 60 days increased in length from 98 to 112% on three different diets. Juvenile Penaeus japonicus held under mass culture conditions for 75 days increased in weight 1877% on a 35% protein diet. In general, all prepared diets produced good growth with low mortality when compared with data reported by other workers.
