x <- scscat(data.frame(date = "2020-07-19", tow.id = "GP001F", tow.number = 1, species = 10, number.caught = 144))
key(x)

# Create 'scsbio' object with specified 'tow.number' and 'sex' fields:
x <- scsbio(data.frame(date = "2020-07-19",
                       tow.id = "GP001F",
                       crab.number = 1:10,
