Question

What are two similarities and two differences between
grouper and bluefin tuna aquaculture.

Answer 1

Similarities:

• Grouper and bluefin tuna are both highly valued meat species that are extensively grown in aquaculture.
• Floating cages or pens are commonly used to farm both species in coastal marine habitats.

Differences:

• Because grouper develop more slowly and require more room, they are often farmed at lower numbers than bluefin tuna.
• Bluefin tuna are often farmed using a process known as "fattening," which involves catching the fish at an early age and raising them in captivity until they reach market size, whereas grouper are typically farmed from juvenile fish until they reach market size.
