Some food for thought ? ( is about carp but read on)
around 35 years ago I went to a British carp study group conference and among the various lectures was one by a fish biologist and spoke about fish going belly up
(I cant remember the exact name)
but what he said basically when a fish is hooked and trys to escape a chemical similar to Adrenalin in humans is released the longer the fight the higher the stress the more this chemical is released
now if the fish is rested for a short period prior to release it allows the fish to calm down and this chemical to dissipate and it can swim away with little ill effects
if however its released to soon the fish can power away and go into shock and go belly up ! he said the older bigger heavier fish are most at risk of this happening
now fast forward 30 years and a French lake owner with some huge carp started getting a lot of the biggest fish going belly up he had a very strict policy of no fish retention
I told him about the above so he bought 50 fish retaining sacks with floats fitted for a trial
and now the rule now is all fish (carp) must be rested for a minimum of 20 mins the result being fish losses in the last 5 years have by dropped by 75%
interesting ???
