Dietary Mineral Requirements of Fish and Marine Crustaceans*
Information concerning mineral nutrition of fish and marine crustaceans is rather limited compated to that available for terrestrial animals; however, significant advances have been made in recent years. This article summarizes pertinent infomation about mineral nitrition of fish and marine crustaceans, including classification and general functions of the minerals; dietary essrnliality and/or quantitative requirments; bioavailability and dietary interactions; and general recommendations for dietary supplementation.

Trace minerals in fish nutrition Takeshi Watanabe *, Viswanath Kiron, Shuichi Satoh
The role of trace elements in biological systems has been described in several animals. However, the knowledge in fish is mainly limited to iron, copper, manganese, zinc and selenium as components of body fluids, cofactors in enzymatic reactions, structural units of non-enzymatic macromolecules, etc. Investigations in fish are comparatively complicated as both dietary intake and waterborne mineral uptake have to be considered in determining the mineral budgets. The importance of trace minerals as essential ingredients in diets, although in small quantities, is also evident in fish. 0 1997 Elsevier Science B.V.
