Fishing Methods
Look at Monterey Bay Aquarium Site
- Bottom Trawl - type of fishing net that’s pulled along the seafloor. Fishermen commonly use bottom trawls to catch shrimp and bottom-dwelling fish like halibut and sole.
- Dredging - Dredges are large, metal-framed baskets that are dragged across the seafloor to collect shellfish like oysters, clams and scallops. High level of by catch.
- Gillnetting - Gillnetting uses curtains of netting that are suspended by a system of floats and weights; they can be anchored to the seafloor or allowed to float at the surface. 4. Harpooning - used to catch large fish
- Jigging - Jigging is another way of hand-catching fish. A jig is a type of grapnel (or grappling hook) attached to a line, which is manually or mechanically jerked in the water to snag the fish.
- Longlining - (50 miles of line with buoy and line with bait)
- Pole and troll - Pole-and-line fishermen use a fishing pole and bait to target a variety of fish
- Hook and line - Day boats use
- Purse Seine - Purse seining establishes a large wall of netting to encircle schools of fish. Fishermen pull the bottom of the netting closed—like a drawstring purse—to herd fish into the center.
- Seine Net - A seine is a small-meshed net, suspended vertically in the water with floats and weights to enclose and concentrate fish.
- Trolling - This hook-and-line method of fishing tows lines behind or alongside a boat
- Traps and Pots - Traps and pots are submerged wire or wood cages that attract fish with bait and hold them alive until fishermen return to haul in the catch.
Mollusk
Bivalve shellfish - two-part hinged shell Types: 1. Clams 2. Mussels 3. Scallops 4. Oysters
PEI Mussels
Prince Edward Island Mussels
Mussel Liquor
Liquid obtained during the mussel cooking process.
Endangered Fish
- Cod
- Bluefin Tuna
- Orange Roughy
Three largest consumers of fish
- Japan
- China
- Spain
Targeted vs Bycatch
Targeted = Catching what is wanted Bycatch = What is not wanted when fishing (Throwaway)
