The Gender and Development (GAD) principle in aquaculture emphasizes:

• That men are solely responsible for all aquaculture activities.

• Focusing only on the marketing and sales aspects of aquaculture.

• Difficulty in utilizing natural productivity.

The concept of 'carrying capacity' in pond dynamics refers to:

• The total volume of water a pond can hold.

• The number of workers needed to manage the pond.
