Fishing techniques using passive fishing gear

Net

A net is installed on the bottom of the sea bed for a given time, during which fish will mesh.

Caught fish are not usually damaged, have beautiful skin and are of excellent quality. However the most fragile species may be marked by the net (such as pollock, for example). Fish caught using nets during short tides are often of excellent quality. With longer tides or in bad weather, particularly if the nets are submerged for an increased period of time, fish can drown and become damaged.

Advantages

  • Selectivity of the net: mesh size adjusted to the targeted species

Disadvantages

  • Loss of the net which “continues to fish”

Species

  • Angler
  • Sole
  • Hake

Line

  • Pole and line fishing or troll lining bring live fish on board; they are often bled and handled with care to ensure optimum quality.
  • A longline involves leaving a line in the water to which baited hooks are attached. Depending on the time between the fish being caught and brought to surface, the fish can be alive and of optimum quality, or, it may have drowned.

Advantages

  • Good selectivity and no impact on the marine environment

Disadvantages

  • Expensive technique using live bait

Trap

Device used to catch crustaceans, whelks and cuttlefish. Prey is attracted by a bait in the trap in the pot.

The pots are weighted before being put in the water and joined together to be left on the sea bed. Crustaceans and whelks are kept alive on board and can be stored in tanks during long tides.

Advantages

  • Good selectivity and no impact on the marine environment
  • Overly small fish can be thrown back while still alive

Disadvantages

  • A technique which is rarely used for fish

Species

  • Whelk
  • Lobster
  • Spinous spider crab
  • Edible crab
