Answer:

longline fishing

Question 2: how far do exclusive economic zones extend

Answer:

extend 200 miles from each nations coastline

Question 3: what are marine reserves

Answer:

where no living organisms can be legally harvested Question 4: rank the three forms of fishing we covered from highest to lowest rates of bycatch

Answer:

trawling is the highest, followed by longline fishing, pole fishing has the least amount of by catch.

Question 5: define the maximum sustainable yield of a fishery

Answer:

the maximum that can be harvested without diminishing the population for future years

Question 6: what are some of the potential problems with aquaculture

Answer:

the high concentrations of fish create huge amounts of manure that flows into the surrounding ecosystem. if the fish are treated with antibiotics or other drugs these will also leake into surrounding ecosystems.

Question 7: individual fisherman use poles lines and baited hooks to catch fish

Answer:

pole fishing Question 8: what kind of animals are vulnerable to becoming bycatch in longline fishing operations?

Answer:

sea turtles, sharks and other fish Question 9: besides bycatch, what ecological damage can be caused by bottom trawling

Answer:

any benthic ecosystems such as coral reefs can be completely destroyed by the weights at the bottom of the trawl net Question 10: explain the difference between territorial waters and exclusive economic zones

Answer:

territorial waters were established first and set boundaries of 12 miles away from shore that only could be fished by the adjoining country. exclusive economic zones extended that area to 200 miles from shore.

Question 11: what does marine trophic index measure

Answer:

measurement of the average trophic level of the total catch from a fishery

Question 12: the position a species occupies on a food chain, e.g. primary consumer.

Answer:

trophic level

Question 13: at what level are annual catch limits established at

Answer:

NOAA

Question 14: MSC Certified

Answer:

MSC Certified- the fish has been sourced from a fishery or facility that pledges to abide by specific standards and practices that promote sustainability

Question 15: aquatic life unintentionally caught alongside a desired species

Answer:

bycatch

Question 16: pole fishing has a low rate of bycatch. what is bycatch?

Answer:

species of fish that are unwanted and accidentally caught

Question 17: explain what these labels placed on fish at the store mean

farmed, wild caught, MSC certified

Answer:

farmed- raised in a mariculture or aquaponics facility. wild caught - caught from a body of water. MSC certification - label attached to any seafood that follows sustainable fishing prices Question 18: there are two ways that trawling and bottom trawling can be damaging to an ecosystem.

• bycatch
• sea floor

Answer:

bycatch: species big enough to be caught in the net will be trapped

sea floor: pulls up coral reefs

Question 19: the practice of raising fish in a confined area in the ocean

Answer:

aquaculture

Question 20: define mariculture

Answer:

the farming of saltwater organisms

Question 21: define aquaculture

Answer:

the process of farming aquatic organisms Question 22: a large net is dragged behind a ship, catching fish larger than the holes of a net

Answer:

trawling

Question 23: Describe the process of pole fishing

Answer:

line is attached to a baited hook which can catch and pull in the fish Question 24: are the US annual catch limits set by NOAA higher or lower than the maximum sustainable yield? why are they set at this level?

Answer:

catch limits in the US are lower than the maximum sustainable yield. this allows for some recovery and increase in the fish stocks from year to year

Question 25: define aquaponics

Answer:

fish farming can be combined with hydroponics Question 26: explain the difference between each of these labels: farmed, wild caught, and MSC Certified

Answer:

Farmed-the fish was raised in aquaculture facility, wild-caught- the fish grew in the wild (ocean, lake, etc), and was caught and harvested by fisherman.
