The experiment was carried out
in a 6-month period prior to spawning of the broodstock rainbow and brown trout
groups fed by commercial fish feed. The study aimed to determine the changes of
fatty acid composition in eggs obtained from broodstock fish which were
spawning for the first time. The fish in each group were selected from the same
age and hatching eggs. The amount of PUFAs between the experimental groups was
not different, while SFA and MUFA amounts were significantly different. The
amounts of oleic acid (C18: 1n9c), linoleic acid (C18: 2n6c) and palmitic acid
(C16: 0) were the highest among the fatty acids detected in broodstock fish egg
groups and their feeds. Total omega-3 (n-3) content was considerably different
between rainbow trout (4.3%) and brown trout (2.89%). The percentages of
palmitic acid, palmitoleic acid, heptadecanoic acid and EPA were significantly
different between the egg groups. Broodstock fishes need to be fed with good
quality feed to give quality eggs in suitable environment conditions. For this
reason, it has been shown that it reflected in the fatty acids of fish eggs
while the breeding fish consume sufficient amounts of essential fatty acids on
the diet. As a result of this situation, it can be ensured that the fish are healthier
and have a higher percentage of life.
