CONCLUSIONS • % Hatch rates at 34” vs 4” the same • Post hatch mortality higher at shallower 4” depth • Eggs incubated at natural depth produce stronger hatchlings with higher in-water survival?
60 day life support system • Amino acids • Fatty acids • Vitamins • Minerals • Antioxidants
Carotenoid differences Lutein, Zeaxanthin Higher levels of PUFAs
Omega 3 and Omega 6 Fatty Acids – building blocks for important hormones
Mice genetically engineered to lack the ability to produce DHA and EPA have fertility problems – low sperm count and mobility The ratio of Omega 3 to Omega 6 Fas in the diet affects the proportion of inflammatory and non –inflammatory Fas procuced.
What is the N3:N6 ratio in wild diet? Turtle grass - 1:1 What is the N3:N6 ratio in CTF feed? Old diet - 1:5
Natural dietary sources of EPA and DHA include: Fish oil (anchovies) Algae (Spirolina) Where do green sea turles get their EPA and DHA?
Sources of alpha – linolenic acid: Flax (<5% limit) Fish Oil ($$) EPA/DHA commercial procuct ($$$$$) Camelina meal?
CAMELINA MEAL • Up to 45% Omega 3 FA • 35-45% alpha-linolenic acid • Rich in antioxidants such as tocopherols • Resists oxidation and rancidity
