1. Who determines regula- WorkSafe BC
tions for EF? (*safety*)
2. Who determines stan- agencies like DFO, provincial agencies, NRTG
dards for EF? (*proce-
dures*)
3. What first aid course is re- Any first aid course that covers *CPR*
quired? What important like Occupational Health and Safety
component must be re-
viewed in that course?
4. List 3 levels of EF Certifica- 1. Crew supervisor (>95% on test)
tion 2. Crew Member (>80% on test)
3. Crew supervisor-in-training (>95% on test but can elect if you want
more experience in the field before running a crew)
5. List 4 ideal conditions re- 1. water temp (7-16 degrees C)
quired for effective back- 2. waist-deep water
pack EF 3. moderate velocity
4. complex habitats
6. Why is the ideal tempera- below 7 = higher impacts to fish -> fish is more conductive than water
ture 7-16 degrees C above 16 = water more conductive than fish, electrical current does not
impact fish
7-16 = fish is as conductive as water
7. What are the units for the 1. Volts
following terms: 2. Amps
1. Voltage 3. Ohms
2. Current 4. Siemens per m
3. Resistance
4. Conductivity

8. What is the Ohm's Law I = V/R
equation
9. Define the variables in I = Current (Amps)
Ohm's Law equation. V = Voltage (Volts)
R = Resistance (Ohms)
10. What is Watts Law - The Power (W) = Voltage (V) x Current (I)
Law of Power equation
11. what happens to P when P increases exponentially
V is increased in Watts (P = V x V/R --> P = V^2/R)
Law
12. List two methods to de- 1. Larger anode ring
crease resistance on an 2. Clean anode ring
electrofishing unit
13. List two methods to de- 1. increase sediment quantity and EF downstream
crease resistance in the 2. add electrolytes to water (salt lick, rock lick)
water
14. What charge does the an- anode ring = positive charge
ode ring have? rat-tail = negative charge
what charge does the
"rat-tail" have?
15. define *Galvanotaxis* involuntary muscle movement/contractions due to electricity towards
the anode.
16. How do fish move during The flexing/relaxing due to electrical pulses moves in a "swimming"
Galvanotaxis? fashion and propels the body towards the anode ring
