| Abstract |
The variation in egg quality, i.e. the potential of the egg to produce viable fry, is still a limiting factor in the commercial production of marine fish and crustacean fry. Better knowledge in this field would contribute to improved and especially more consistent hatchery outputs and to the development of more suitable broodstock diets. So far, objective criteria to evaluate egg quality are scarce. However, it is very likely that the nutrient composition of the eggs may be a good indicator for egg viability as it reflects the nutrient demands of the developing embryo and larva. Since (n-3) highly unsaturated fatty acids (HUFAs) have been identified as essential nutrients for the larvae of marine fish, shrimp and prawn a case study has been initiated with the giant freshwater prawn Macrobrachium rosenbergii to verify variations in (n-3) HUFA contents of eggs from wild and pond-reared broodstock. |
