Case Study: Orange Roughy |
| |
a |
Depending
on the type of specimens you can obtain, this could be
extended to a full dissection exercise, locating the swim
bladder, comparing flesh texture, etc. |
|

The
orange roughy's low productivity and slow growth make
it vulnerable to overfishing. You could also discuss the
importance of scientific research in assessing stock size
and safe fishing levels. Because orange roughy are found
so deep, scientists have special problems in researching.
For example, it is very difficult to take live specimens.
There are still big gaps in knowledge about its biology. |
