Nutrition is also an important aspect in juvenile production. Newly hatched red claw occupy a very small territory (a few square inches). Therefore, feed must be distributed throughout the tank so that juveniles will have access to it both on the bottom and within the mesh. Several diets have been used to rear juveniles in the hatchery. At the present time, the best recommendation is to feed a high protein (>33 percent) commercial shrimp diet. Juveniles should be fed at 40 percent of estimated biomass per day, with the feed being fed over three to five feedings a day. Improved survival and growth have been obtained by feeding brine shrimp (Artemia) during the first week. Newly hatched brine shrimp nauplii are best but frozen adult brine shrimp have been used. Brine shrimp can be substituted for one of the daily feedings of formulated diet. Care should be taken to ensure young crayfish have all they can eat without overfeeding. Overfeeding can quickly cause deterioration of water quality. Excess food should be removed from tanks by siphoning daily. Feeding behavior and water quality should be closely monitored
