Title

Fatty acid changes in embryonic and larval stages of (Sparidentex hasta)

Pages

  85-94

Abstract

 With the development of aquaculture in the marine fish sector, the identification of the nutrient composition required by larvae in the early stages of life has more considered. Despite the obvious importance of nutrition in the development of larvae of Sparidentex hasta, which is an economic species in aquaculture at; the south of the country, due to the small size and sensitivity to manipulation of marine fish larvae, little information is available about nutritional needs. Embryo and yolk sac compounds are affected by reproductive nutrition and according to the vital role of fatty acids in membrane permeability in the larval stage; it is possible to increase the survival rate of larvae by proper management of the fatty acid compounds required at the beginning of initial feeding (dry food or live food enrichment). In this study, samples were taken in three stages of gastrula, at the time of yolk sac uptake and three days after complete yolk sac uptake (beginning of active feeding). It was then stored in liquid nitrogen and-80 ° C freezer until laboratory work was performed using GC gas chromatography. The most abundant fatty acids were oleic and palmitic and there was a statistically significant difference in different stages of fatty acids (P<0. 05). According to the results in SFA and PUFA up to larval stage, the trend was increasing, and in MUFA, oleic, it was a decreasing trend. The reduction of some fatty acids is because of energy consumption and further increase is for the role of storage, especially in membrane tissue. Therefore, the amount and ratio of fatty acids in the early stages of the life of the Sparidentex hasta determines the minimum larval requirement in the initial diet.
