Answer:

Approximately 22,000 metric tonnes of fish per year

Explanation:

From the graph,

Rate of decline :

(metric tonnes of fish in 1965 - metric tonnes of fish in 1995) / range of years

(700,000 - 40,000)metric tonnes ÷ (1995 - 1965)

660,000 metric tonnes ÷ 30 years

660,000 / 30

= 22,000 metric tonnes per year

Approximately 22,000 metric tonnes of fish per year
