Abstract
Fatty acid composition of ovules (ovulated oocytes) from kutum (Rutilus frisii kutum) was investigated to assess their relationship to gonad biological characteristics, larval size, fertilization, and hatching success. Forty-eight kutum were captured in the wild during the spawning season. Results revealed an inverse relationship between linoleic acid (18:2n-6) and ovule weight (P < 0.05). Arachidonic acid (20:4n-6) and eicosapentaenoic acid (20:5n-3) contents showed a direct correlation with the number of ovules per gram (P < 0.05); the latter had an inverse relationship with the ratio of surface to volume (P < 0.01). There was a direct and significant correlation between docosahexaenoic acid (22:6n-3) and ovule weight (P < 0.05). High unsaturated fatty acid levels indicated a direct relationship with egg and yolk diameters and also an inverse correlation with ovule surface to volume ratio (P < 0.l05). Direct relationships were found between polyunsaturated fatty acids and the diameter of egg and yolk as well as the ratio of surface to volume (P < 0.05). There was a direct correlation between saturated fatty acid content and the number of eggs (per gram) (P < 0.01). Total lipid and weight of newly hatched larvae represented a direct relationship (P < 0.05). Despite living in brackish water and migrating to fresh water during the reproductive season, kutum exhibited greater similarity in ovule fatty acid composition to saltwater fish than species in fresh water. Moreover, with respect to biological characteristics, this species shows more significant relationships with n-3 fatty acids than with n-6 fatty acids.
