Does fish size/sex have some effects on its shelf-life in ice storage condition?
Thanks in advance for your replies.
Yes.
Size is the important criteria which determines the Shelf life of fish in Ice-Storage.Small fish of the same species spoil very quickly when compared to the larger one, this is due to the rapid penetration of spoilage bacteria in small size fishes with thinner skin and muscle.
In general, flat shaped fish keep longer than round shaped fish; red fleshed fish keep longer than white fleshed fish; low fat fish longer than high fat fish and teleost (bony) fish longer than elasmobranch (cartilaginous) fish.
Hello,
Yes, I think so. fish size may reflect fish age (the larger fish, the older one). Since, whole body biochemical composition (importantly lipid content and lipid classes) and enzymatic activity (importantly lipolitic and proteolitic) change over the life span of the fish, their susceptibility to degradation alter at different age. Also, if the fish are from the wild resources (sea or river), older fish may have higher oxidant (heavy metal for instance) in their body, which alter shelf life. In the case of sex, body biochemical composition and enzymatic activity differ between the sexes, so the shelf life differs, too.

Thank you all for your answers, but could you please recommend me some references?
