'The sampling was done at Barbey Packing Corp. unloading dock. The days 

 sampled are denoted by an asterisk. The entire catch was sampled for those 

 days. The number of fish landed at Barbey on the days not sampled was esti- 

 mated by using an average weight of 4.28 kg/fish which was calculated by 

 dividing 23,417 kg sampled by 5,477 fish sampled.
