Harvesting the Sea
“Although it is not a weight, the equivalent of a cran is 28 stone. A barrel of herring would need approximately four baskets of fish to fill it. (2 baskets for a half barrel if it was salted herring)
A full barrel of salted herring required 2 baskets plus an extra full basket and 1 firkin.
A basket of herring was 7 stones. Four baskets made a cran.
In the old days the fish were salted but not now. They work in tons now. There are 3 or 4 crans in a ton.
A scaffie would carry up to 40-odd crans. That is 160 baskets. A trawler would bring in 800 boxes or 200 crans.” (John Patience)
