Question 1

The difference(s)between fishing and aquaculture is/are:

Accepted Answer

A) Fish populations in aquaculture operations are more genetically homogenous than wild ones that are caught by fishing fleets. 
B) Highly developed nations harvest more fishes from the ocean while developing nations produce much more seafood by aquaculture. 
C) The limit on the size of a catch in fishing is the size of the natural population,whereas the limit on aquacultural production is primarily the size of the area in which organisms can be grown. 
D) All of the above are differences between fishing and aquaculture

B) Coral bleaching. 
C) Nonpoint source pollution. 
D) Habitat destruction. 
A) Loss of ocean biodiversity. 
B) Coral bleaching. 
C) Nonpoint source pollution.

Question 3

Which of the following about coastal development and its impacts on the marine environment is/are FALSE

Accepted Answer

A) Development of resorts,cities,industries,and agriculture along coasts alters or destroys many coastal ecosystems,including mangrove forests,salt marshes,sea grass beds,and coral reefs. 
B) Although only 50 countries have coastal management strategies,their goals are broad as not only do they address issues related to economic development of the thin strips of land that directly border the oceans but they also integrate the management of both land and water. 
C) Currently about 3.8 billion people (some 60% of the world's population)live within 150 km of a coastline and demographers project that perhaps as many as 6.0 billion people (about 75% of all humans)will live in coastal area by 2025 making sheer human numbers the main cause of coastal degradation. 
D) No false statement,all of the above (a,b,& c)are true.

B) Increased salinity from diversion of freshwater for human use. 
C) Increased oxygen concentrations from algal blooms due to nutrient pollution. 
D) Increased predation by parrot fish due to overfishing.
