Hyperpressurization is not the only problem for smallmouth bass caught in night tournaments.

Enter more science again:-Largemouth/Smallmouth Tournament Bass Kills

Smallmouth bass do die quicker than Largemouth bass, because of hypoxia, sustained low oxygen saturated environments commonly found in aerated tournament boat livewells containing limits of fish during summer tournaments. A reduced tolerance for hypoxia would therefore largely explain why smallmouth bass are less tolerant of summer tournament procedures than largemouth bass.

Bass tournament kills are much worse in summer night tournament than day tournaments. RE: no photosynthesis at night - environmental water becomes hypoxic - livewell water is hypoxic before you put the first fish in the box - a loose, loose deal for the fish kept in aerated bass boat livewells especially at night.

There are sound reasons why tournament mortality is worse in night C&R tournaments.
