Hi all, I'm having trouble estimating the TL from a couple of cleithra
with depth/height (of the thickest part) of around 32 mm I have in the
past used a formula supplied by the ever useful Leif Jonsson, but it
breaks down with fish of larger than about 70 cm TL (depth about 23 mm),
giving lengths that are too great - on 32 mm it gives monster fish - I
know they are going to be large, but not Jonah sized! Does anyone have
a formula using large specimens or simply a few comparable specimens
with known length please?
