Fish Flashcards
What is a “TAC” in regards to fishing?
Total allowable catch. Established through scientific assessments of the state of fish stocks
How do you define the process of managing fish stocks?
The population or total mass of a fishery resource. Such stocks are usually identified by their location of the resource in the ocean
What is an example of unsustainable fishing?
Bottom trawling
What is an example of sustainable fishing?
- “La Peche Raisonnable” - small scale fishing with boats smaller than 10m
What is the importance of seasonality in terms of fish production?
- Quality
- Protect reproduction period
- E.g. oyster season is september - april, outside these months they reproduce, taste creamy
What aspects do you look at to recognise the quality of fresh fish?
Flesh - firm, no bruising, rebound when pressed
Eyes - Clear, bulging, bright, moist
Gills - Bright maroon/red, moist
Smell - Non-offensive
Humidity - Scales tightly attached, clear mucus coating
How do you tell the freshness of shellfish?
- tightly closed
- heavy for their size
Describe hook, line and troll fishing
- Most selective of techniques
- Dishing rod, controlled by one person
- Can be used for many types of fish
- Can have multiple hooks attached to the one line
Describe long line fishing
- Multiple hooks attached to a line
- Line is dragged from a boat, with boys attached to each hook
- Catches multiple fish at the same time
Describe drift net fishing
- A net is hung off the side of a boat or close to the shore
- Specific sized holes to capture certain sized fish
Describe Purse Seines fishing
- Net is placed around a group of fishing, keeping the fish in a certain area
- Fisherman then captures the fish with a hand-held filet
- this allows fragile species such as anchovies, sardines, bonito to be captured with care
Describe trap fishing
- A bait is set inside of a trap
- Traps are attached to buoys
- Traps are brought to the surface and onto the boat
Describe midwater trawler fishing
- Controversial
- A large cone shaped net is dragged through the ocean, collecting anything in its way
- Used to fish most ocean species
Describe bottom trawler fishing
- Large net is dragged along the ocean floor, destroying and collecting anything in its way
Describe the characteristics of white and round fish
- E.g. cod, bass, pollack
- Overall softer, flakey meat
- Lower fat content
- Less iodine flavour
- Only some can be eaten raw
- Normally roasted, sometimes ceviche
