Turkish Journal of Veterinary & Animal Sciences

This study was conducted to determine the effect of nutritional stress due to reduction in the number of feeding days during the fifth instar of parental larva on the parental and following genaration for larval and cocoon traits. Mulbery leaves were provided during the fifth instar for different durations of 1, 2, 3, 4, 5, 6 and 7 days, which were regarded as treatment. The normal span of feeding of these larvae were 8 days which was considered as control. A lot of larvae mortality occured due to feeding for 1 and 2 days therefore, these treatments were not considered. …

The Importance Of \Omega-3 Series Fatty Acids In Marine Fish Larvae Nutrition And Recent Developments, Abdurrahman Polat, Gülsün Özyurt Jan 1999

The Importance Of \Omega-3 Series Fatty Acids In Marine Fish Larvae Nutrition And Recent Developments, Abdurrahman Polat, Gülsün Özyurt

Turkish Journal of Veterinary & Animal Sciences

In general, marine fish larvae require \omega-3 HUFA, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Larval growth, survival and larval activity are affected by dietary levels of essantial fatty acids. Some pathological signs, such as abnormal pigmentation, hydrops etc. and low feed conversion efficiency, poor growth, mass mortality are related to \omega-3 HUFA series fatty acids deficiency in larvae food. EPA/DHA ratio in live foods or microencapsuled diets is an important factor in larval development and survival.
