stocks with missing catch data?

For the following stocklongs, the number listed is the number of years for which there are Udiv and/or Bdiv values, but no TCbest values in the same year. There is probably a good explanation for most of these (e.g. catch in numbers, not MT, or else Bdiv time series extend back earlier than recorded catch data), but for some of them, catch should be in MT and it's surprising they have so much missing catch data. I'm only listing the ones with >=5 years of missing TCbest data. I'm only listing the subset of stocks in the SNAPP analysis.

Could you look into these stocks and check that there are good reasons for missing catch data?
