Marine biotechnology can be used to produce genetically modified (GM) fish with preferred traits. Some opponents of genetic modification argue that the release of these fish can have a negative impact on natural ecosystems. Is this a valid concern, and can anything be done to minimize the impact on nature

Incomplete question. The options;

a) yes, gm fish could alter biodiversity if they mate with fish in the wild. This impact is best minimized by producing gm fish that are sterile.

b) yes, gm fish can alter biodiversity if they mate with fish in the wild. This impact is best minimized by tracking the released fish and capturing them.

c) no, gm fish cannot impact natural ecosystems because they are likely to die in the wild. There is no need to be concerned about the impact to nature.

d) no, gm fish cannot impact natural ecosystems because they are designed.

e) there is no need to be concerned about the impact to nature.

a) yes, gm fish could alter biodiversity if they mate with fish in the wild. This impact is best minimized by producing gm fish that are sterile.

Explanation:

Indeed, genetically modified (GM) fish basically refers to fish whose natural traits have been edited or adjusted by scientists. For example, they may be modified in such a way that they feed more and grow faster than is usual for wild fish. Biodiversity is altered when these GM fish begin to consume more food and also producing offsprings with similar traits, over time this would make it difficult for natural wild fishes to find food; reducing their population, thereby impacting nature.

However, if GM fish are produced to be sterile (ie cannot reproduce offsprings), it could easily lead to a balance in the population of the natural ecosystem.
