In birds, egg binding might cause yolk peritonitis, septicaemia or etc. What about in fish? Do they absorb the eggs? Do the eggs accumulate and become solid?
When hormone is injected it is not necessary that all eggs are hatched. Within the ovary the mature eggs are biologically absorbed as in the case of any other animal. this will be followed by next cycle of ovulation process depending on the species.
My experience is that with the injection of hormone (Ex: Ovaprim) as a releasing agent, eggs final maturation occur and if they do not spawn naturally or by striping septicemic condition might occur and brood fish might die in due course. we should ensure water hygienic condition. Most of the time overripe eggs may biologically absorbed and refurbish at the next cycle.
Thank you Mr. Alappat Ramachandran and Mr. Manoshantha Epasinghege Don. There was a case of Dystocia in a Jade Perch, the fish had died 3days post stripping. Accumulated eggs, which were quite solid, were found in both ovaries, so I suppose that poor fish somehow could not absorb the eggs and septicaemia might have killed it. I wonder why the eggs accumulated and couldn't be absorbed.
It will be better if you could inject 10% BW before 24 hrs. of the prime dose. When you performing striping, try to take out all the eggs. You can start striping at the anterior of ovary and gradually come to the end and perform this two three time. Mot of the time, eggs may not remain in the ovaries.
after first stripping you should wait some hours and remove eggs again. Ovulation is a dynamic process and after stripping eggs will continue to ovulate. Obviously, it is a trade off between removing all eggs and handling stress, but a second stripping after some time is recomendable. Keep in mind that you should optimise the interval between first and second stripping yourself...
