Question

Lionfish have become an invasive species since their introduction into the Atlantic Ocean, where they have few natural predators due to their venomous spines and quick reproduction. They feed voraciously on native reef fish and mollusks, negatively impacting coral reef biodiversity. How can scientists further investigate the spread and impact of lionfish in order to develop potential solutions to this issue?
Encourage divers to report sightings of lionfish to update current maps
Introduce more fish and mollusks for the lionfish to feed on
Study maps of lionfish sightings prior to 1995
Use a remotely operated underwater vehicle (ROV) to capture lionfish

Answer 1

The last one sounds like a good idea

Answer 2

Answer:

Option D, Use a remotely operated underwater vehicle (ROV) to capture lionfish

Explanation:

ROV stands for remotely operated vehicle where a person sits at the surface of sea or ocean and operates this device. ROV is basically a maneuverable underwater robot that is used for collecting various types of data under the water.

In order to observe the Lionfish, it would be essential to use ROV because only then exact movement and number of this species could be traced accurately. Instance sights traced by divers will not help in any way. Since it is an invasive species, it would be better to keep a strict check on it and find solution for its eradication.  

Hence, option D is correct
