Top 10 Questions for Fish Seiner Interview

1. What is the process of locating a school of fish using sonar equipment?

The process of locating a school of fish using sonar equipment involves transmitting sound waves into the water and analyzing the returning echoes. Sonar equipment typically consists of a transducer that emits sound waves and a receiver that detects the returning echoes. The transducer is usually mounted on the hull of the vessel and emits sound waves in a cone-shaped pattern. The sound waves travel through the water and reflect off of objects in their path, including fish. The returning echoes are then detected by the receiver and processed to create an image of the underwater environment. The image can be used to identify the location and size of schools of fish.

2. How do you determine the best net size for a particular fishing operation?

Factors to consider when choosing a net size:

• Target species: The size of the net should be appropriate for the target species. A net that is too large will allow smaller fish to escape, while a net that is too small will not be able to catch larger fish.
• Fishing area: The size of the net should also be appropriate for the fishing area. A net that is too large may be difficult to maneuver in tight quarters, while a net that is too small may not be able to cover a large enough area.
• Environmental conditions: The size of the net should also be appropriate for the environmental conditions. A net that is too large may be difficult to use in strong currents or high seas, while a net that is too small may not be able to withstand rough conditions.

Procedure for determining the best net size:

• Consider the factors listed above.
• Consult with other fishers in the area.
• Experiment with different net sizes to find the one that works best.

3. What are the different types of fishing nets and their advantages and disadvantages?

• Gill nets: Gill nets are made of a thin, transparent material that is suspended in the water. Fish swim into the net and become entangled in the mesh. Gill nets are relatively inexpensive and easy to use, but they can be indiscriminate and can catch non-target species.
• Trammel nets: Trammel nets are similar to gill nets, but they have three layers of mesh. The outer layers are made of a larger mesh size than the inner layer. Fish swim into the net and become entangled in the inner layer. Trammel nets are more selective than gill nets, but they are also more expensive and difficult to use.
• Seine nets: Seine nets are large, rectangular nets that are used to encircle a school of fish. The nets are then hauled in, trapping the fish inside. Seine nets are very effective, but they can be expensive and difficult to use.
• Trawl nets: Trawl nets are cone-shaped nets that are towed behind a vessel. The nets are designed to catch fish that live near the bottom of the ocean. Trawl nets are very effective, but they can be destructive to the environment.
• Purse seines: Purse seines are large, rectangular nets that are used to encircle a school of fish. The nets are then closed at the bottom, trapping the fish inside. Purse seines are very effective, but they can be expensive and difficult to use.

4. How do you operate a purse seine net?

To operate a purse seine net, the net is first set out in a circle around the school of fish. The net is then closed at the bottom, trapping the fish inside. The net is then hauled in, bringing the fish on board the vessel.

5. What are the different types of fishing vessels used in fish seining?

• Purse seiners: Purse seiners are large vessels that are used to catch fish using purse seine nets.
• Lampara boats: Lampara boats are smaller vessels that are used to catch fish using lampara nets.
• Trawlers: Trawlers are vessels that are used to catch fish using trawl nets.

6. What are the safety hazards associated with fish seining?

• Drowning: Fish seiners work in close proximity to the water, and there is always a risk of falling overboard and drowning.
• Entanglement: Fish seiners work with large, heavy nets, and there is always a risk of becoming entangled in the nets.
• Injuries from fishing gear: Fish seiners use sharp knives and other tools to process fish, and there is always a risk of injury.
• Exposure to the elements: Fish seiners often work in harsh weather conditions, and there is always a risk of exposure to the elements.

7. What are the environmental impacts of fish seining?

• Bycatch: Fish seiners often catch non-target species, which can be a threat to the ecosystem.
• Habitat damage: Fish seiners can damage the ocean floor and other marine habitats.
• Pollution: Fish seiners can release pollutants into the ocean, such as oil and fuel.

8. What are the regulations governing fish seining?

Fish seining is regulated by a variety of laws and regulations. These regulations vary from country to country, but they generally cover the following areas:

• Gear restrictions: The type of fishing gear that can be used for fish seining is often regulated.
• Area closures: There may be certain areas where fish seining is not allowed.
• Seasonal restrictions: There may be certain times of year when fish seining is not allowed.
• Catch limits: There may be limits on the amount of fish that can be caught using fish seining.

9. What are the future prospects for fish seining?

The future prospects for fish seining are uncertain. The industry is facing a number of challenges, including overfishing, climate change, and pollution. However, fish seining is still an important method of fishing, and it is likely to continue to be used in the future.

10. What are your career goals?

My career goals are to become a successful fish seiner. I want to learn as much as I can about the industry and to develop the skills necessary to be a successful operator. I am also interested in becoming involved in the management of the fishery, and I hope to one day be able to contribute to the sustainable development of the industry.
