Step 1: Understanding the Concept:
Evaluating different fishing gear requires an understanding of their structural designs, operational mechanisms, and regional applications.
Detailed Explanation:
- Analysis of Statement (I): Verandah nets are specialized barrier nets designed to catch fish that jump out of the water when startled (such as grey mullets, Mugil spp.).
The gear consists of a vertical barrier net that blocks the path of the fish, combined with a horizontal floating "verandah" net that catches the fish when they jump over the vertical barrier.
Because they function by intercepting and blocking fish movement, they are classified as barrier traps.
Thus, Statement (I) is true.
- Analysis of Statement (II): Chinese dip nets (locally called "Cheena vala") are large, shore-operated lift nets.
These nets are mounted on large bamboo or teak wooden structures and operated using counterweights.
They are a well-known feature and are widely used in the brackish backwaters of Kerala (particularly around Kochi and Kumbalangi) for catching fish and shrimp.
Thus, Statement (II) is true.
Step 2: Final Answer:
Both Statement (I) and Statement (II) are true, which corresponds to option (1).
