ANCHOVY EVENTQuick Reaction Checklist

GENERAL RULE # 1:When in doubt, turn on all aerators.

ANCHOVY EVENTQuick Reaction Checklist

GENERAL RULE # 2:There are five criteria for turning on the aerators. If any combination of these leads you to feel there is a fish stress condition occurring, turn on the aerators:

Concentrations of fish inside the harbor. Anytime the fathometer shows that 1/2 or more of the harbor depth has fish, turn on the aerators.

Large concentrations of fish near the harbor entrance. If large fish schools (1/2 mile in width) are at the harbor entrance in the evening, turn on the aerators for the night.

Low oxygen readings. Turn on any time readings are 3.5 PPM or less.

Fish under stress. If fish are jumping in a large area, a kill could be imminent -- turn on aerators.

When in doubt, refer to General Rule #1 (turn on aerators).

ANCHOVIESCLEAN-UP MOBILIZATION

The Port District will mobilize the Crisis Action Team (CAT):

Port Director – (PD)Harbormaster – (HM)Port Engineer – (PM)Facilities Manager – (FM)Administrative Services Manager – (AS)OPS personnel - other – (OPS)FME personnel – other – (FME)

During the regular work week there will be immediate mobilization. If on a weekend, or after hours, the CAT will assemble as soon as everyone can be called back. The mission of the CAT after a kill is clean-up of the water and shore areas as soon as possible by removing anchovy carcasses. Every ton that we remove can save days of anaerobic water conditions and attendant health and safety problems.
