Key result
Post-mortem ageing of carp and rabbit muscles caused rapid disappearance of the connectin band 1 component and an increase in band 2, with a faster rate of disappearance in carp muscle.
Population
Fish (seven species, including carp) and rabbit skeletal muscle

Fish connectin quantification extends myofibrillar data across species; leaves open titin roles in cardiac sarcomere mechanics.
This basic science study demonstrates that post-mortem ageing causes qualitatively similar but kinetically different degradation of connectin in fish versus rabbit muscle.
Seki et al. (1984) studied this question. Post-mortem ageing was evaluated on Connectin content and submolecular composition changes. Post-mortem ageing of carp and rabbit muscles caused rapid disappearance of the connectin band 1 component and an increase in band 2, with a faster rate of disappearance in carp muscle.
