Description:
In the first chapter, all documents in aquaculture feed, feed formulation, nutritional requirement and basic
concepts of aquatic feeding had been collected. The second chapter focused on broodstock feeding in order to
improve reproduction effecieny . The third chapter performed to importance of live food specially in sturgeon
fishes larvae and the forth chapter attended to biology and ecology of this fishes and finally in the fifth chaper,
special nutrition and feeding in sturgeon fish larvae had been brought with all the works out in Iran on. There
are 63 documents including papers, thesis and reports from different research library and universities among
them 34 base on sturgeon larvae nutrition specially on Huso huso and Persian sturgeon species and almost there
are not any documents on the other three species. 14 documents comes from the role of protein, energy and lipid
replacements basically in the first growth year, 3 of back to the special nutrition requirement of Persian and
Huso huso species and 12 were on digestive enzymes physiology, the role of probiotic and prebiotic on growth
and survival rate. Almost there is not any organization in Iran to work on this species specificly and it seems
every student and researcher paid attend to a narrow way of high way sturgeon fish researches. There is not any
data bank on these important fishes and some repeated worked out by researchers in different parts of the
country.
Beside of this documents there had been gathered some research documents from the other countires for
comparing and showing the correct way in this regards. First, we must focus on broodstock sturgeon feeding,
then on egg and yolk analysis, larval stages, morphology, measurement of larval mouth and finding the best live
food for different stages of sturgeon larviculture and finnaly on digestive physiology and enzymatic activities. In
the stage of shifting from endogenous to exogenous feeding, nutritional requirement, protein digestibility,
essential and free amino acids, essential fatty acids spcially PUFA and HUFA, vitamins, minerals, pigments,
growth and survival stimulants and resistance to physiological environmental stress are very important to search.
