TEXT: Paragraph 4
Once the dead or dying bycatch is returned to the ecosystem, it is consumed by predators, detritivores (organisms that eat dead plant and animal matter), and decomposers (organisms that break down dead or decaying organic matter), which could have a positive effect on sport fish, seabird, crab, and even shrimp populations. Available evidence indicates that 40–60 percent of the 30 metric tons of catch discarded annually by commercial fishing vessels, and even more of the noncatch waste (organisms killed but never brought to the surface), does not lie unused on the bottom of the sea. It becomes available to midwater and oceanbottom scavengers, transferring material into their food web and making energy available to foragers (organisms that search for food) that is normally tied up in ocean-bottom, deepocean, midwater, and open-ocean species.
QUESTION 6:
According to paragraph 4, how does bycatch sometimes benefit sport fish, seabird, crab, and even shrimp populations?
-
(A) The discarded fish provide these species with a significant amount of food that would otherwise be unavailable to them.
-
(B) Fishing eliminates up to 40 to 60 percent of the predators of these species, most of which are caught unintentionally.
-
(C) These fish and other animals may be caught unintentionally in overcrowded locations and then released into more favorable environments.
-
(D) Many of the competitors of these species are eliminated by fishing, leaving them with access to more food and other resources.
