Is the problem low yield or degraded DNA? If the problem is strictly low
yield, you might try a different tissue, gill for example. If it's a
problem of degradation, you might try adding 5 mM EGTA to the digestion
buffer (assuming you are using proteinase K digestion).

Just out of curiosity, what are you using the genomic DNA for?
