5203 |a"Survey results for the 1990 and for the 1991 acoustic herring surveys in Chedabucto Bay are presented. The 1990 surveys showed individual nightly abundance estimates of over 350,000 tonnes and an average abundance of about 220,000 tonnes between Jan. 6 and Jan. 8. The abundance dropped to about 39,000 tonnes on Jan. 10, and stayed low until the end of the survey on Jan. 24. The average abundance from Jan. 10 to Jan. 24 was about 19,000 tonnes. This is very strong evidence that the herring left the area around Jan. 10"--Abstract, page 2.
