Long-term Behavioral Tracking of Freely Swimming Weakly Electric Fish
Published on: March 6, 2014
Summary
Electric current offers theoretical efficiency for whale killing, but experiments with electric harpoons yielded inconsistent results due to technical issues, making it an unreliable method.
Area of Science:
- Marine biology
- Wildlife management
- Electrical engineering
Background:
- Whaling practices historically employed methods with varying efficacy and ethical considerations.
- Electric current presents a theoretically humane and efficient mechanism for dispatching large marine mammals due to anatomical factors.
Purpose of the Study:
- To evaluate the efficacy of electric harpoons as a humane and efficient killing method for whales.
- To compare the performance of electric harpoons against traditional detonating grenade harpoons in terms of killing time and consistency.
Main Methods:
- Review of previous experimental trials using electric harpoons for whale capture.
- Analysis of data on killing times and technical challenges encountered during electric harpoon deployment.
Main Results:
- Experiments demonstrated a reduction in killing time compared to detonating grenade harpoons.
- Significant technical problems were encountered, leading to inconsistent and unreliable results.
- The method's uncertainty precluded its adoption as a viable alternative.
Conclusions:
- Despite theoretical advantages, electric harpoons are currently too unreliable for practical whaling applications.
- Further technological development is required to overcome technical hurdles before electric current can be considered a viable killing method for whales.

01:10Electrical Energy
Using electric appliances for a longer period of time consumes more electrical energy and results in a higher electric bill. The energy produced by the transfer of electrons from one point to another is known as electrical energy. If power is delivered at a constant rate, the electrical energy can be defined as the product of power used by the device for a period of time. The energy unit on electric bills is the kilowatt-hour, where one kilowatt-hour is equivalent to 3.6 × 106 joules. The...
01:10Faraday's Law
Faraday's law state that the induced emf is the negative change in the magnetic flux per unit of time. Any change in the magnetic field or change in the orientation of the area of the coil with respect to the magnetic field induces a voltage (emf). The magnetic flux measures the number of magnetic field lines through a given surface area. Magnetic flux is estimated from the integral of the dot product of the magnetic field vector and the area vector. The negative sign describes the direction in...
01:24Back EMF
Generators convert mechanical energy into electrical energy, whereas motors convert electrical energy into mechanical energy. A motor works by sending a current through a loop of wire located in a magnetic field. As a result, the magnetic field exerts a torque on the loop. This rotates a shaft, extracting mechanical work from the electrical current sent in initially. When the coil of a motor is turned, magnetic flux changes through the coil, and an emf (consistent with Faraday's law) is induced.
