Review: Use of Highly unsaturated fatty acid (HUFA) in Ornamental Fish Feeds

Histological and fatty acids changes in Caspian salmon (SalmotruttacaspiusKessler, 1877) fed diets with different levels of vitamins E and highly unsaturated fatty acids (HUFA)

In this study, the combined effect of different levels of dietary n-3 HUFAs with α-Tocopherol on changes in the structure of intestine and pyloric caeca and fatty acids profile of Caspian salmon, Salmotrutta caspius, fry (initial weight of 600 ± 25 mg for 10 weeks) were investigated. Six experimental diets containing three different dietary levels of n-3 HUFAs (Low: 1 + 0.5, DHA+ EPA, Med...

A review of the role and importance of essential fatty acids in the feeding of ornamental fish

Ornamental fish farming, like other aquaculture productions, it depends on the quality and quantity of egg production, hatching, fecundity and survival of the larvae. In general, every step of aquaculture, followed by nutritional goals. Most of these studies are in the stages of larval growth. Because the highest costs are imposed on aquaculture and the most critical biological period of orname...

Gammalinolenic Acid, an Unsaturated Fatty

Unsaturated Fatty Acid Biosynthesis in Tetrahymena

The ciliate Tetrahymena pyriformis synthesizes a wide variety of saturated and unsaturated fatty acids. Variations in growth temperature or the addition of sterols such as cholesterol or ergosterol alter the proportions of a number of unsaturated fatty acids. The pattern of substitution is complex when examined on the basis of individual fatty acids. A straightforward explanation is possible, h...
