Juvenile cuttlefishes (14 g) ingested pellets routinely after 4 days and the feeding rates ranged 6.4-8.1% bw.dl. The cuttlefishes doubled their weight in 57 days although 7 of 20 were cannibalized. The moist, pelleted diet appeared to be palatable to both octopuses and cuttlefishes but the reduced growth rates for cuttlefishes and no growth exhibited by the octopuses fed the pellets suggest that nutritional deficiencies or imbalances exist. The results demonstrate that pelleted diets can be used to maintain cephalopods and modest growth can be expected at this stage of diet development. The disadvantages of lower growth rates are offset by the cost savings compared to expensive natural diets that require high labor costs for collection and maintenance.
