Ice baths or chilling of farmed fish on ice or submerged in near-freezing water is used to dampen muscle movements by the fish and to delay the onset of post-death decay. However, it does not necessarily reduce sensibility to pain; indeed, the chilling process has been shown to elevate cortisol. In addition, reduced body temperature extends the ...
"Frozen eggs are just as safe as fresh eggs," Dr. Brian Labus, an assistant professor in the School of Public Health at the University of Nevada Las Vegas, and an infectious disease epidemiologist ...

The surrounding egg white floats perfectly around the yolk, membrane intact. One of the divers was even able to make the egg 'dance' around by manipulating the current of the water around it.
Fish chilling with slurry ice. Slurry ice can boost by up to 200% the cooling efficiency of existing cooling or freezing brine systems without any major changes to the system (i.e. heat exchanger , pipes, valves), and reduce the amount of energy consumption used for pumping.
Extracting the egg sacs from fresh (unfrozen) herring, as done in the past was a delicate operation. According to the description of pre-industrial herring processing at Esashi in Ezo country, it is observed that even the removal of the fish from gillnets without scarring the eggs inside involved recruiting inveterate fishermen.
