One of the problems with shrimp (and other crustacean) culture is broodstock diets and nutrition. Currently, most hatcheries around the world are using fresh or frozen squid, worms (polychaetes), fish and other marine organisms, topped up with nutritional additives. This practice is far from ideal, exposing the cultured animals to potential pathogens and diseases, nutritional inconsistency and is dependent on wild fisheries. Considering the cost of broodstock (especially SPF), these are serious risks and in many cases result in high mortality and/or reduced productivity, leading to significant financial loss.
Until now, broodstock fed maturation formulated dry diet, pelleted or extruded did not match the performances of animals fed on fresh/frozen food. The dry diets tend to break down due to the unique feeding behaviour of the animals, resulting in polluted water and very high FCR. Moreover, palatability and ingestion rates are usually low.
Recently, NutrKol developed maturation diet (NutraFeed® diet range) for crustacea that can completely replace the use of fresh/frozen feed. The diet is semi-moist and manufactured as short pellets at any length and diameter needed. The diet is stable in the water for 24 hours and will not break down when the shrimp or lobster is holding and chewing it.
NutraFeed® diets were tested with several crustaceans including; white shrimp L. vannamei, tiger prawn P. monodon (wild and domesticated), bugs (T. orientalis) and tropical lobster (Panulirus ornatus). The diet can be designed and manufactured to any crustaceans.
NutraFeed® diets are based solely on dry meals without any fresh or frozen products. They are pathogen free (all ingredients pass Gamma radiation) with a shelf life of six months (refrigerated) or 12 months (frozen).
Herbal extracts (NutraGreen® products) are incorporated into the diets. These 100% natural additives aimed at improving broodstock performances including; enhancing egg and larvae quality, sperm motility, vitellogenesis, as well as immune system and digestive system support.
Currently, three different maturation diets are manufactured according to species: NutraFeed® SM for shrimps and prawns, NutraFeed® LM for lobsters and bugs and, NutraFeed CM for crabs.
