The linear regression fitted to log length and number of oysters per sack was highly significant (adjusted r 2 = 0.93, F 58 = 809, p < 0.0001), and yielded the following predictive relationship between the number of oysters in a known volume and the mean oyster length: h = 10 (−0.3537 log b + 2.8361) , where h is SH (from umbo to growth edge) in millimetres, and b is the number of oysters in a 52.85 l volume (standard Louisiana sack).
