Ascites is a "quick and dirty" way to make a lot of antibody- if you are
none too concerned about animal welfare. I think we should always consider
alternatives to using animals where possible- and there is certainly no
necessity to use ascites. 
I have no experience with hollow fibre, but a simple approach is to grow
hybridomas to large volume in roller bottles or similar, then purify the
antibody over a protein A column or similar. 

Ascites are very impure: There are plenty of horror stories of "ascites
artifacts" around. You would have to purify them before use anyway, so why
not spare the animals and grow them in plastic bottles?
