Passive fishing gear – is characterized by the absence of gear movements and/or the pursuit of the target species; such as, but not limited to, hook and line, fishpots, traps and gill nets across the path of the fish.
What is the difference between active and passive fishing gears?
With passive gears, the capture of fish is generally based on movement of the target species towards the gear (e.g. traps), while with active gears capture is generally based on an aimed chase of the target species (e.g. trawls, dredges).
What are active gears in fishing?
The term “active” means that the fishing gear is dragged through the water by human, animal or engine power. In most cases the efficiency of active gear is considerably higher than that of “passive” gear, such as gillnets and traps, which rely for their efficiency on the movement of the fish themselves.
What are the advantages of passive fishing gear?
A distinct advantage of many passive gears is that effort is easier to control than it is for most active gears. With passive gears, such as gill nets or trap nets, effort is generally expressed in terms of a “standard set” with a specific kind of gear and time interval.
Is cast net active or passive?
Observation
| E (Hook and line) | F (Cast net) |
|---|---|
| Catches do not include dirt | Catches may include dirt |
| May require use of bait/attractant | Does not require use of bait/ attractant |
| Passive gear | Active gear |
| Catches fish from any part of water (surface, bottom) | Catches fish from water surface |
What are the two most productive municipal fishing gears?
On the other hand, the gillnet and hook and line were the most productive for municipal fishing gear, producing 32.85% and 23.87%, respectively (Table 11).
What is ghost fishing gear?
What is ghost fishing gear? Ghost fishing gear includes any abandoned, lost, or otherwise discarded fishing gear, much of which often goes unseen.
Can active gear be a passive gear and vice versa?
Fishing gears fall under two general categories, active gear and passive gear. Active gears are designed to chase and capture target species, while passive gears generally sit in one place allowing the target species to approach the capture device.
Which net is passive net?
Passive Gears. Gill nets are walls of netting which may be set at or below the surface, on the seabed, or at any depth in between. Gill netting is probably the oldest form of net fishing, having been in use for thousands of years.
What is hook and line?
Hook-and-line means a type of fishing gear consisting of a length of fishing line, to which is attached one or more hooks or other device for capturing marine life. A weight and a pole may also be used to aid in the placement of the fishing line in the water.
What is gill net fishing?
Gillnetting is a fishing method that uses gillnets: vertical panels of netting that hang from a line with regularly spaced floaters that hold the line on the surface of the water.
What is aquaculture and why is it important?
Aquaculture is breeding, raising, and harvesting fish, shellfish, and aquatic plants. Basically, it’s farming in water. U.S. aquaculture is an environmentally responsible source of food and commercial products, helps to create healthier habitats, and is used to rebuild stocks of threatened or endangered species.
What are the most common fishing gears?
Common fishing gear types
- Demersal or bottom trawl. What’s bottom trawling?
- Gillnets. What’s gillnet fishing?
- Longlines. What’s longline fishing?
- Purse seine. What’s purse seine fishing?
- Pole and line. What is pole and line fishing?

Which net is used for active fishing?
Trawls. Trawl net is conical bag nets with two wings and codend where the catch is concentrated, performed by towing from one or two boats. The size of a trawl net may be defined by the length of the foot rope, headline or the number of meshes around the fishing circle, and the mesh size at that point.
What method of fishing is with hooks and baits?
Angling
Angling – refers to using a hook attached to a line to catch fish. Angling is almost always done with some type of bait and sinker on the hook. It can be done on the shore, off a dock, or on a boat.
What is the difference between aquaculture and capture fisheries?
While fisheries are solely related to catching wild fish or raising and harvesting fish, aquaculture is a science that involves all aspects of marine life. 3. While fisheries can be saltwater or freshwater, wild or farmed, an aquaculture can be Mariculture or an integrated multi-trophic aquaculture type.
What are the 3 branches of fishery?
The Philippine fisheries industry comprises marine fisheries, inland fisheries, and aquaculture.
Is the Philippines rich in fish?
The Philippine archipelago is rich in marine and inland water resources that contribute to the country’s fisheries industry. Every day, the country’s thousands of fisherfolk catch fish, engage in gleaning, raise aquatic resources through aquaculture, and sell their catch at markets.
What is the largest fishing ground in the Philippines?

| 2. Iloilo Fish Port Complex | Barangay Tanza, Iloilo City | 21.00 Ha |
| 3. Zamboanga Fish Port Complex | Sangali, Zamboanga City | 12.50 Ha |

Why can’t we use nets to simply scoop up the marine debris?
Cleaning up marine debris is not as easy as it sounds. Many microplastics are the same size as small sea animals, so nets designed to scoop up trash would catch these creatures as well. Even if we could design nets that would just catch garbage, the size of the oceans makes this job far too time-consuming to consider.
Is ghost fishing illegal?
Illegal, unreported and unregulated (IUU) fishing also contributes considerable amounts of ghost gear, as illegal fishers abandon or discard fishing gear to conceal their activities. Sometimes fishing gear is also discarded into the ocean deliberately.
