Aquatic animal supplementation practices – survey results and recommendations

Aquatic animals have been maintained under human care for centuries. Limitations in the variety of foods available to feed to these animals as well as the use of frozen/thawed diets make supplementation of some nutrients necessary. Limited research has been done on what vitamins or minerals are necessary and in what amounts. There are no standardized requirements or recommended daily...

Plasma electrolyte concentration for African penguins (Spheniscus demersus) and their relationship to habitat type and salt supplementation

African penguins are common display animals in North American zoos and aquariums. At present 43 American Zoo and Aquarium (AZA) accredited institutions, maintaining over 700 African penguins, participate in a species survival plan (SSP) for this species. There are currently some institutions that maintain their birds in freshwater without salt supplementation. No associated health issues have been reported by these...

Testing a vitamin supplement paste in Jackass Penguins (Spheniscus demersus)

According to the literature, piscivorous species fed dead, frozen fish in zoos have been shown to require supplemental vitamin E and thiamin (Engelhardt and Geraci, 1978, Robbins, 1993). The Rotterdam Zoo supplemented jackass penguins (Spheniscus demersus) with extra vitamins since 1991 by injecting liquid vitamins into the defrosted pilchards (Sardina pilchardus), mackerel (Scomber scombrus) and herring (Clupea harangus) fed to...

Penguins: nutrition and dietary husbandry

Provision of nutritional, behavioral, and environmental requirements is basic to the successful maintenance and reproduction of captive penguins. The following guidelines for nutrient intake and dietary husbandry were developed from studies of natural feeding ecology, published nutrient requirements of related species, information on potential penguin foods and their nutrient composition, and evidence of food preferences. Penguin foods are perishable and...

Penguin diet and nutrition

Meeting the nutritional needs of penguins is essential if they are to survive and reproduce in captivity. Developing appropriate dietary guidelines involves using information 1) from feeding ecology data, 2) from published nutrient requirement data 3) on food availability to zoos and 4) on food preference. It is also essential to store and process food items correctly and provision the...
