Dear friends,
It's a good discussion whether the younger ones to be spared or the older
ones to be spared during fishing.
But the ethics/principle is neither there should be any recruitment over
fishing nor the growth over fishing.
To control the growth over fishing: we have to spare the younger ones
To control the recruitment over fishing: we have to spare the older ones
Another principle/ethics in fisheries management is " we should give a
chance to individuals to breed at least once in their life time."
For the stock assessment for fisheries management the calculation of the
Length at maturity (Lm50), generally helps the fisheries scientist to decide
the minimum size of the species to be caught.
No fish less than Lm50 should be caught for the fisheries management
purpose.
Again we should not catch the broods or there should not be any fishing
during the breeding seasons so that there should proper recruitment in the
ecosystem.
Thanking you for these discussions.
Kindly provide your valuable suggestion on my comments.
With best wishes,
--
